3 1. INTRODUCTION 1.1. Overview In conjunction with its Sustainable Building Program, the Los Angeles Community College District (LACCD) is committed to utilizing the tools of Building Information Modeling (BIM) to execute the design, construction and management of its new High Performance buildings. The LACCD BIM Standards have been developed to define a process and establish requirements, procedures and protocol for the utilization of BIM in the various stages of our projects. These Standards are based upon the National Building Information Standards (NBIMS) and reference the current technology Standards developed by the General Services Administration (GSA), the US Army Corps of Engineers (USACE), Industry Foundation Class (IFC) by the International Alliance for Interoperability (IAI), and OmniClass Construction Classification (OmniClass) as developed by the Construction Specifications Institute (CSI) Main Objectives of It is the intent of LACCD BIM Standards to facilitate the use of BIM technologies and workflow to achieve the following goals: 1. Develop high performance buildings using sustainable design concepts. 2. Facilitate a collaborative project environment between all stakeholders from project inception to completion 3. Execute coordinated project documents using the 3D modeling and parametric features of BIM 4. Improve system coordination and the execution of design intent in the field to streamline construction processes and minimize change orders 5. Utilize 4D Technology and Process to better manage transition from design to construction and virtually simulate construction processes with various trades to avoid conflicts in the field 6. Incorporate as-built BIMs, including infrastructure and building systems, in to Districtwide Geographical Information System (GIS) 7. Collaborate with District-wide Facility Management to incorporate as-built information in to facility management tools and software 8. Incorporate submission of the BIM as a requirement for Division of the State Architect (DSA) electronic review and approval 9. Establish a technology platform and provide continuous support to incorporate future technologies 10. Use BIM as Information and Communication tools for shared governance, students, facility directors and staff, and the community 1

LACCD Revit Template Files 2014 (for teams using Revit 2014) (see APPENDIX - Technical Footnotes & Diagrams, item e) 2.0 BIM PROJECT REQUIREMENTS 2.1. Summary Mandatory BIM Project requirements shall include the modeling, visualization, documentation and analytic processes of the building design, as shall assist in validating the scope and cost of the project. The principal objective of using BIM is to improve the quality of design solutions and the exchange of information between the parties. This requires collaboration between the Design Team, the Design-Bid-Build Contractor, the project management team, campus facilities teams, and LACCD. 2.2 Technology Platform and Software LACCD accepts true 3D solid modeling, object oriented software applications that comply with current industry interoperability standards and are able to be used in a collaborative environment. The models and analyses shall be used in support of the decision making process for high performance building design. All software platforms used for LACCD projects MUST be compliant with: Most current version of Industry Foundation Classes (IFC) file format Commercially available collaboration software that provides interoperability between the different software applications (e.g. NavisWorks or equal) 2

5 Approved BIM Software for LACCD Projects*: Software Authoring Design Team(Architecture, Structural) Authoring - MEPF Equipment (Design Team & Construction Team) Authoring - MEPF Distributions (Design Team & Construction Team) Available Revit Architecture, Bentley BIM, ArchiCAD, Tekla or equal Revit MEP, Bentley BIM, ArchiCAD, or equal Revit MEP, AutoCAD MEP, Bentley BIM, CAD-Duct, CAD-Pipe, AutoSprink, PipeDesigner 3D or equal Authoring - Civil Coordination (Design Team & Construction Team spatial conflict, clash detection) 4D Scheduling** Cost Estimate Energy Analysis Bentley Inroads and Geopak, Autodesk Civil 3D NavisWorks Manage, Bentley Navigator Clash Resolution, Tekla BIMSight Synchro, Vico, NavisWorks Simulate, Primavera, MS Project, Bentley Navigator Innovaya, Vico or equal Green Building Studio, IES, Ecotect, Hevacomp, TAS, or equal E-Specs or equal Solibri or equal Specifications Model Checking Validation, IFC File Optimizer Water Management Bentley WaterGem * Software other than those listed below may be used subject to the above compliance requirements and approval by LACCD Staff. **Software should link a Primavera or MS Project schedule to model 1. MEPF Equipment is defined as model objects used for building performance calculations, such as Title 24 Energy Regulation, and as required in sections and MEPF Equipment (including, but not limited to: Light Fixtures, Air Handling Units, Chillers, VAV boxes, Plumbing Fixtures, etc.) is required to be created by true 3D solid modeling, object oriented software applications, such as Revit MEP. 2. MEPF Distributions is defined as the as-built fabrication runs of plumbing pipes, mechanical pipes, conduit, fire sprinklers and mechanical ducting created in fabrication models. This can be created by (true 3D solid modeling) object oriented software, such as Revit MEP, or by (object enabled 3D surface model) fabrication software, such as AutoCAD MEP, Autodesk CAD-Duct, AutoCAD Developer CAD-Pipe, AutoCAD Developer AutoSprink, Trimble PipeDesigner 3D, or equal. 2.3 Applications of BIM BIM output can be utilized in a variety of ways to provide stakeholders with a greater understanding of how a building is to be used, designed, and constructed. As such, the expectation shall be that the BIM shall serve as a virtual representation of the actual building where traditional 2D documentation (i.e. plans, elevations, sections, schedules, 3D perspectives, isometrics, and details) are extracted and fully coordinated with the concurrent model. 3

6 The various applications in which BIM shall be utilized for all LACCD BIM projects shall be as follows: Pre-Design and Programming For each campus, The District shall develop Programming Requirements which shall define space and adjacency requirements to be adhered for individual projects. These requirements shall be based upon the campus Education Master Plan and Facility Master Plan, and shall reference the Owner s Basis of Design and Sustainable Design Guideline Documents. As-Built Records of Existing Facilities, and, BIM /GIS mapping of campus shall be included in this documentation and provided to project teams for their use during the RFP phase. Where possible, all programming and as built data provided by the campus shall be in a format that is fully translatable to an IFC Compliant BIM Authoring Tool and shall be expected to be incorporated by the Design Build Teams in to their design processes for reference and verification purposes As-Built Asset Data Teams should begin with the end in mind in relation to parameter metadata within model objects. As defined in sections 2.3.4, 2.3.5, , and e, model objects must contain asset data encompassing three categories: Description Metadata Populated by the Design Team; completed by 100%DD Performance Metadata - Populated by both the Design Team and Construction Team; completed at 100%DD, Installation and Construction Substantial Completion M&O Metadata - Populated by the Construction Team; completed at Installation or Construction Substantial Completion The full list of the required Asset Data for each BIM object in a project can be found within the following spreadsheet: DES-0002-D BIM Asset Data for Design and As-Built Documentation - New Construction and Renovation A full description of the specific metadata used by LACCD - including parameter naming, parameter units and parameter examples for the Asset Data defined in form DES D can be found in the following spreadsheet: DES-0002-E Parameter ID Definitions for the BIM Asset Data Matrix DES-0002-D Spreadsheet It is suggested that the teams utilizing Revit organize and code the Asset Data using the objects keynote parameter. It is also suggested that the teams utilize the Revit template file titled LACCD Revit Template File V1 to organize model objects and schedule asset data using the template s pre-made Revit schedules. See APPENDIX - Technical Footnotes & Diagrams, item e for additional explanation and information COBie Team will be required to utilize the COBie data format for adding some of the description and performance metadata in the model objects as defined in DES-002-D and DES-002-E. 4

7 The Construction Team will be required to utilize the COBie data format for adding M&O metadata of MEPF equipment utilized by the LACCD Facilities Group as defined in DES-002-D and DES-002-E. The Design Team will also be responsible for the export of the description, performance, and M&O metadata of MEPF equipment from the model to a COBie-compliant excel file Site Conditions - Existing Conditions and New Construction For new construction and renovation projects, the modeling of the project site and massing of adjacent existing structures is required. Depending upon the project site, a BIM sit model of the site may be obtained from LACCD. If no existing site models are available, the Design Team shall develop this model as a part of the scope of work. For renovation projects, the modeling of project buildings shall be performed based upon District provided as-built information, with field verification or electronic measurements conducted by Project team to validate the level of accuracy. For all existing conditions to be directly impacted, altered, or to be demolished by a proposed renovation, the Design Team shall model those conditions to the appropriate level of detail that will clearly demonstrate the design intent to building stakeholders, other Project Team Members, and construction trades directly involved with executing this scope of work. Proposed site conditions shall reference campus benchmarks, and reference existing surveys and GIS mapping systems for accuracy. New site and utility conditions shall be modeled in 3D, and shall coordinate system and spatial models three dimensionally. In cases where landscape features may directly impact utility and structural systems, those features (i.e. vegetation, irrigation) shall be modeled with accurate size and clearance zones Architectural Model - Spatial and Material Design Models The Architectural Spatial model evolves during the design process, and the information modeled by the Design Team in BIM shall be further refined as a project progresses toward construction. In the early phases of design, an Architectural BIM Model may be as simple as a massing model validating program requirements, basic geometries, building orientation to climate and site conditions, and adjacency to the surrounding building s for contextual impact. As the design progresses, design solutions shall be clearly documented and delineated by the Design Team in the building information model. Likewise, as materials and components are selected, generic assemblies shall be assigned material properties, sizes, track LEED values, and other specific component information to clearly define various building features such as walls, floors, roofs, doors and windows. Program space requirements shall be modeled in the spatial model and validated using schedules and other validation tools designated by the District for the specific project. 5

8 2.3.5 System Models - Structural and MEPF design Each building system shall be organized as a separate model linked to a common origin point or campus benchmark for efficient and accurate coordination purposes. Similar to the spatial models, the level of detail in these models shall evolve as design progresses such that these systems are accurately modeled, and include sufficient quantity, location, performance, clearance, asset data, and LEED requirements as part of the BIM. Design Team consultants responsible for multiple systems may include those systems in a single file with each system clearly identified, as long as each system is able to be extracted independently for systems coordination. For building performance calculations, systems must be further broken down in respect to their locations by the Design Team - specifically individual rooms, spaces, or zones associated with a system or systems. The architectural model and drawing sheets assign rooms for both schedule and areas. The mechanical, electrical and plumbing model assigns spaces to the corresponding room areas. The assigning of spaces creates a volume to track the location of equipment and fixtures. In the case of a mechanical System (ex. defined by an Air Handing Unit), the associated mechanical equipment (to include VAV, reheat, and diffusers) are assigned to a System through metadata properties. Once a System is defined, the Zone defining elements (ex. VAV, sensors, and thermostats) are assigned to a specific Zone through metadata properties. Finally, mechanical equipment (ex. diffusers, return) which occupies a specific space coincides with the metadata properties that assign both System and Zone Cost estimation LACCD may use the model to generate Cost Estimates at project milestones designated by the contract. At the completion of Construction Documentation Phase, the Design Team shall also provide to potential bidders a copy of the fully assembled and coordinated BIM in a non-editable format. (i.e. Navisworks.nwd,.dwf, 3d.pdf). See section for additional cost-related requirements for quantity takeoff D Scheduling and Sequencing - Schedule-Based Model Views The construction planning process mandates the sequencing of activities in space and time and accounting for constraints such as procurement lead time/logistics, resources, and spatial constraints, among others. Having the ability to watch the elements of a design come together visually gives the design and construction team improved accuracy in construction sequencing. Creating Schedule-Based Model Views offers an effective tool to gauge and visualize a team s actual work progress in relation to the submitted schedule. Sequencing may also be used for visualizing the installation of a complicated assembly that may require coordination of multiple contractors. 6

9 Models and their Elements must be in concert with the Activity IDs within the Project Schedule. However, LACCD does not require a 4D animation. Instead, LACCD requires the creation of Schedule-Based Model Views: isolated 3D views representing a specific snapshot point of the schedule. Views which break down the site and basic system assemblies per-trade and per-floor linked to a resource-loaded construction sequence schedule, shall be adequate. See Table 1 - Schedule-Based Model Views Assemblies and Activities Matrix - for a description of system assemblies and activities. The intent of the creation of these views is for Design Teams and Construction Teams to better visualize the baseline construction schedule and analyze the sequencing for any projected constructability impacts during the project. During Design: The Design Team shall create views within the BIM to break down (by floor and by trade) the MEPF systems. During Construction: The Contractor shall provide adequate time in their submittal schedule prior to the start of construction to complete a pre-construction coordination process using BIM for CPT/PMO review and approval which shall include the following: 1. Constructability review of Contract Documents Design BIM. 2. Construction VDC Kickoff Meeting to review BIM requirements and BIM Execution Plan with District. 3. Provisions and timeline for development, submission and review of Fabrication 3D Files and continued Schedule-Based Model Views. 4. Coordination and modeling of proposed underground utilities with existing and updated for any unforeseen conditions uncovered during construction, as discovered. 5. Identification and review of potential design Changes for approved Substitutions prior to their installation in the Project. 6. Identification and resolution of potential changes for constructability issues prior to their installation in the project Contractor shall provide Schedule-Based Model Views to visualize snapshots of construction activities on site per requirements of the BIM Standards. Additionally, Contractor shall prepare Schedule-Based Model Views to account for work breakdown structure (WBS), phases, levels and/or zones, as specifically noted in the Contract Documents. The CPT/PMO team may request use of the Schedule Based Model Views as a means for reviewing construction progress, and submitted Applications for Payment. As such, it shall be the responsibility of the Contractor to update the Model (and hence Model Views) regularly for review at construction progress meetings. 7

11 D Estimation / Model-based Quantity Take-off Quantities shall be directly derivable from the model by LACCD at 50%DD and be represented in model schedules such that the following take off can be extracted: Square feet (rooms, GFA, walls, glazing, slab penetrations, etc) Linear feet (columns, walls, framing, etc) Counts (MEP equipment, air terminals, etc) Energy Consumption Simulation and Life-Cycle Cost Analysis All new construction needs to be designed in a way that energy and material use can be greatly reduced and then measured and verified by facilities management teams once it is occupied. As such, energy simulation shall be based upon information extracted directly from BIM technology and validated by energy modeling, whole building commissioning requirements and LEED Certification. Exporting to gbxml - Project Design Teams and Construction Teams shall utilize energy modeling and sustainable design software that extracts BIM data to gbxml format for analysis. Reference section 2.2 for approved BIM Authoring Tools Design Visualization Design Visualization tools refer to animations, fly-throughs, static 3D renderings, 4D, and 3D Physical Models exported directly from a BIM Authoring Tool. Design Teams shall provide a model which will support the creation of quality design that illustrate building spaces, their use and organization, to assist stakeholders in making decisions throughout the design duration. During Construction, visualization models may be developed by the Contractor to help simulate and sequence construction of a room before it is built. 2.4 Modeling Requirements General 1. The BIM shall be used for all site and building systems design, development, and analysis, including but not limited to architectural, structural, mechanical, electrical, plumbing, and fire suppression. 2. During SD and DD Phases, BIM Technology shall be used by the Design Teams to develop and establish building performance, and the Basis of Design in accordance with Owner Project Requirements (OPR). This model shall be interoperable with analytic tools including but not limited to building envelope, orientation, daylighting, energy consumption, building management system (BMS), building automation systems (BAS), renewable energy strategies, life cycle cost analysis, and spatial requirements. 3. Use BIM authoring software element libraries when creating model objects. Model objects shall contain parts and components assigned to appropriate Families and Categories as opposed to simple 3D Geometry (i.e. walls, doors, windows, railings, stairs, furniture) 9

12 4. Model objects/elements shall contain object parameters and associated description and performance asset data (Description Metadata and Performance Metadata) applicable to building system requirements. These elements shall contain data at a level such to support the analytic process - including size, material, location, mounting heights, performance parameters and system information where applicable. As an example, a light fixture may contain parameters such as energy output requirements, user illumination levels, description, floor level, space name, bulb life, ID tag, etc. See Section for additional asset data information and DES-002-D for a full list of BIM asset data for design and as-built documentation. 5. Some model objects/elements shall also contain object parameters and associated asset data applicable to Maintenance and Operations by facilities (M&O Metadata). These elements shall contain data at a level to support the maintenance of facilities including manufacturer, model number, installation date, warranty start and warranty duration.

Other critical spaces as required e) Access panels 2.5 Drawing Requirements (CAD Files) Drawing Requirements pertain to standards for output of models such as file naming, line work, font styles, title blocks, symbols, text styles, printing requirements, and other LACCD standard content. In addition to these BIM Standards, all LACCD Projects shall refer to sections 2.0 through 20.0, and the referenced appendices of LACCD CAD Standards 3.0 for drawing requirements. 2.6 Project Folder Structure and ProjectWise General Design Teams and Construction Teams on Projects requiring use of LACCD BIM Standards and/or LACCD CADD Standards shall be required to utilize LACCD s ProjectWise System for file exchange, data management, and submission milestones. All projects requiring the use of ProjectWise shall adhere to the requirements outlined within the BIM Standards. However, at the discretion of each college, additional requirements may be identified within Contract Documents pertaining to ProjectWise use on the project ProjectWise Use Design Teams and Construction Teams awarded contracts with the LACCD BIM Standards and/or LACCD CADD Standards are each also required to acquire a minimum of one ProjectWise Passport for access to the LACCD ProjectWise Server. Proof of purchase of ProjectWise Explorer licenses must be provided to LACCD within 30 days of their Notice to Proceed. 13

16 2.6.3 ProjectWise Folder Structure \Design Construction\30 BIM-CAD\ For teams choosing to collaborate in ProjectWise, the current version of the live models and drawings shall be located in the BIM-CAD section at all times. \Design Construction\Milestone Submittals\ Milestone submission models shall be copied to the Milestone Submittals folder. Files placed in the Milestone Submittal Folders are snapshots of the project at a given point in time based upon requirements of the project schedule. Milestones are organized by Year-Month-Date, and then the name of the submittal (i.e. 100% Construction Documents). A sample Submittal file structure is shown in Section BIM Submission Folder Structure and Naming Maintaining consistent file naming and structure is critical for referenced (linked) files to function properly across project teams and for end users such as facilities directors, to be able to retrieve files quickly once the project is complete. For this reason, LACCD has developed a filing structure to organize BIM Files and other deliverables for the duration of the project. This folder structure has been integrated in to LACCD s ProjectWise Folder Structure and supersedes our previous BIM Folder Structure. All documentation pertaining to Milestone Submittals shall be archived and stored within the project file structure with a heading corresponding to the submittal type (i.e. 100% Construction Documents). A sample file structure is shown below: 14

17 1. Sample Folder Structure Milestone Submittals See Section for additional discipline designations. The root location (drive letter) of the Project folders may differ from office to office. However, all LACCD project data should be independent of the root drive letter to allow sharing between differing office server structures. The Root project Directory (LACCD) must reside directly below the Drive letter: 2.

Folders consist of the 3 character Campus code, and shall be placed directly below the LACCD Project Directory as shown above. 4. Project Number Prior to commencing work, project teams shall be assigned an LACCD Project Number by the College Project Manager. This number shall be used for organizing the project files, and should include the common name on the file name project. (Example: Mission College CPM assigns the East Complex project a project number of 04M-418. Therefore project folder shall be named 04M-418 East Complex) 5. Discipline Folders Each discipline shall be assigned a folder corresponding to a Discipline Designator as listed in Table 2. All project files received and referenced from each discipline shall be organized in this folder. As a project progresses, the contents within these discipline folders will expand, and each deliverable should be clearly organized in its own folder. Discipline Designators Table 2 Discipline (in alphabetical order) Architectural Geotechnical Civil Process Electrical Fire Protection General Hazardous Materials Interiors Landscape Mechanical Facilities / Operations Plumbing Equipment/Specialty Design Structural Telecommunication Security Survey Civil Works Other Disciplines Contractor/ Shop Drawings Designator A B C D E F G H I L M O P Q S T TY V W X Z 16

20 2.7 Information Delivery Manual (IDM) The Information Delivery Manual is a methodology to document a team s intended process of exchanging information using BIM tools to develop sustainable design solutions, the process maps shall be used to validate the design intent, and document the process for future projects. As part of a BIM Execution Plan, Design Teams shall provide: IDM Process Maps documenting the teams strategy for executing energy analyses, verification of geospatial requirements, project water management, and daylight harvesting analysis. These process maps shall be tied to specific requirements and performance goals of the project. It is the intent that these process maps be in compliance with the Information Delivery Manual (IDM) published by the Building Smart Alliance. (IDM link: ) Sample IDM Process Map Source AEC3 18

21 2.8 Data Security The Design Team or Construction Team shall establish a data security protocol as part of the Design BIM Execution Plan or Construction BIM Execution Plan. The intent of the data security plan is to establish user permission levels and prevent any possible data corruption, virus infections, data misuse or deliberate damage by his/her own employees. Design Teams and/or Construction Teams shall establish usernames and passwords for each individual accessing LACCD s ProjectWise system. Conversely, if there is a need to access any non-laccd provided file exchange servers, it shall be the responsibility of the Design Team and/or Construction Team to provide the necessary access rights for LACCD s users/stakeholders as needed. 2.9 Model and Electronic File Ownership 1. Construction VDC and Fabrication 3D Files shall become the property of District and transmitted along with the As-Built Drawings upon Final Completion. 2. Any electronic files provided by Architect or District on the Project may not be used wholly or in part for any purpose other than the preparation of Shop Drawings or construction coordination for the Project. 3. Copying or distribution of any electronic media file in whole or in part to parties other than a party to the Project is not allowed. 19

22 3 BIM PROCESS AND IMPLEMENTATION 3.1 General The project BIM Implementation Plan, defined below in Section 3.2, is intended to be used as a guideline to incorporate BIM as an integral part of LACCD's design, construction and facilities management processes. These standards shall be considered Project BIM requirements for implementation of BIM processes. Any deviations to the guidelines outlined herein must be documented by the applicable Project Team, and then reviewed and approved by LACCD in writing prior to commencement. As technology progresses, LACCD will work with project teams to update these requirements accordingly. Additional BIM requirements may be included in the Service Agreements, General Conditions, or Supplementary Conditions, at the discretion and approval of LACCD Program Manager. 3.2 BIM WORKFLOW PROCESS BIM Workflow Summary a. Design Phase 1. Design Team shall assign a Lead BIM Facilitator to coordinate BIM workflow per section 3.4 of LACCD BIM Standards. 2. Designers shall use trade specific analytic and authoring tools to create 3D models to meet predefined project requirements. 3. For Spatial Coordination, BIM Facilitator will integrate the design discipline and trade specific models into a consolidated 3D-model using coordination software (i.e. Navisworks, Bentley Navigator). The consolidated model will be used for assembling the various design models and providing a report and view list of design coordination issues. 4. Resolution of Spatial Conflicts: During coordination meetings, the Design Team will electronically identify, track and publish interference reports between all trades. All interferences will be resolved interactively by the Design Team facilitated with the use of coordination software. 5. Prior to each scheduled coordination meeting, an updated clash report will be issued by Project Team BIM Facilitator to track the progress of coordination, analyze conflicts and help facilitate issue resolution prior to construction. 6. Spatial Coordination Sign-off Drawings: Once all spatial conflicts have been resolved by the Design Team and the structural, architectural, MEPF, and Civil systems have been fully coordinated, each consultant shall provide fully annotated drawings of their respective systems in PDF format for submission to the Architect / Engineer of Record for review and approval. The fully coordinated model shall be used as reference model for the construction team to coordinate compliance of fabrication models with design intent, and shall be updated in a timely manner to reflect design changes in the field. 7. Building Performance and Energy Modeling Design Team shall regularly update energy models using BIM Data as reference. Information generated from Design Energy models shall be integrated into design models as appropriate to achieve building performance and energy efficiency goals of the project. 20

23 8. DSA Review and use of digital models for approval will be developed in collaboration with DSA by LACCD as technology progresses. b. Bidding Phase (if applicable) 1. As part of documents delivered to potential bidders, Design Team shall provide non-editable version of the coordinated BIM for reference and visualization of the building. 2. After Contract is awarded, the coordinated Design BIM and all native BIM files will be provided to the General Contractor for basis of construction. c. Construction Phase 1. Prior to the start of construction, Contractor shall assign a Team VDC Manager to coordinate fabrication models with the coordinated design model. 2. Construction Trades noted in Section c shall generate fabrication models using Design BIMs that have been issued for construction. 3. Contractor s Fabrication models shall be coordinated with the design BIM that is based on DSA approved design. Prior to fabrication and construction Contractor shall report any potential discrepancies to the design model to Design Team in the form of a RFI. Clash reports may also be issued by the Contractor as background information for RFIs and submittals. 4. As part of the requirement for as-built deliverables, the Contractor shall continually update the Construction BIMs with as-built conditions, including changes to MEPF systems Project Team Collaboration Procedures The success of a BIM enabled project delivery process is highly dependent upon the level at which the entire project team can communicate and work collaboratively for the duration of the project. This section documents the recommended collaboration procedures for effectively managing this process. a. Shared File Server - Prior to start of design, it is required that the Design Team establish their own single shared project server (or ProjectWise 30 BIM- CAD folder as defined in Section 2.6.3) for the upload and exchange of digital models, and the collection of project deliverables at pre-determined milestones. The same shared server shall continue to be used for the same purposes during Construction. Models on this shared server will be fully accessible webbased to all team members via assigned site user names and passwords. When a LACCD provided shared file server (ProjectWise 30 BIM-CAD folder) is used, Project Teams shall coordinate with the District to establish access. 1. Upload Models to Shared Project Server - During the Design Phases, design engineers and architects will upload their trade specific authoring and analysis models to the shared Project Server for scheduled coordination meetings and milestone submittals. 2. Design Models uploaded for clash detection and systems coordination should be saved in an optimal interoperable format agreed upon by project team. (i.e. Navisworks accepts several file types but.dwg,.nwd/.nwc, and.ifc are file formats that are operable across multiple software platforms) 21

24 b. Coordinated Insertion Point Prior to the start of design in BIMs, BIM Facilitator shall work with project teams to establish a geospatially coordinated insertion point for all disciplines to begin their models. See Section of BIMS and Section 8.0 of CAD Standards for additional information on how to establish insertion points. c. Points of Reference BIM facilitator will provide a 3D grid for incorporation into the spatial coordination model. This will provide the viewer with a quick point of reference when navigating through the model. If room information is easily translatable to the coordination model, this should also be incorporated. d. Project BIM Kickoff and Standards Orientation Upon award of a project, LACCD shall facilitate a Design BIM Standards Kickoff Orientation with the Design Team to review the following: 1. LACCD BIM Standards and Workflow process 2. Statement of Owner s Project Requirements 3. All data developed during the project validation phase 4. Asset Data requirements BIM Standards will also be reviewed with selected General Contractor prior to the start of construction as part of the Construction BIM Standards Kickoff. e. Third party involvement - Project Teams are encouraged to seek involvement of selected third parties, such as DSA reviewers, local utility companies and other stakeholders that may benefit from a visual review of the coordination model BIM Collaboration Room ( BIM Theater ) During the Design Phases, the Design Team Prime Consultant should provide a room (BIM Theater) for facilitating BIM Collaboration. The BIM Theater shall serve as a collaborative work environment for design review and coordination. Alternately, collaboration using web conference (i.e. WebEx, GoToMeeting) is acceptable for facilitating these meetings. During Construction, Contractor should provide and set up a BIM Collaboration room located at the construction site to coordinate fabrication models with respective trades and design team to review the submittals. 22

25 3.2.4 Spatial Model Coordination and Clash Detection Figure 2 Illustrates the BIM based coordination process during design and construction phases D-Models, Formats and Model Structures of Coordination Models The 3D models shall consist of 3D objects and solids (not lines or wire frames) that closely represent the actual dimensions of the building elements and the equipment that will be installed on the project. In the Design Model, reasonable abstractions can be made (i.e. pipe fittings do not need to be modeled), and shall be coordinated with the Builder to ensure meaningful coordination and clash detection. Before coordination modeling begins, the construction Virtual Design and Construction (VDC) Manager will work with team to develop a structure and features of the files that are to be submitted (Documents: File Structure, Modeling Scope Matrix). Typically, BIM Coordination requires the following model structure and features: 1. Project teams shall follow LACCD File Naming requirements as documented in Section For buildings with a larger footprint or multiple floors, team may wish to create a single coordination. One file for each floor (or zone) of one floor and trade (e.g. 4 floors, 2 wings per floor, and 5 trades => 40 files) 3. For trades, the 3D representations of each floor may be relative to a 0-0 FFEL as long as all trades agree on the same protocol. The BIM facilitator will adjust the elevations of the architectural and structural elements to All other trades will be modeled at the correct elevation (not all floors modeled at the same elevation). 5. All elements of the building must be represented in only one file and should be modeled by their specific trade. For example, the Architectural model provided for 3D coordination should not include any of the structural elements contained in the structural model. Lights should be modeled by the electrical engineer, not the architect. 6. The Architectural ceilings should contain openings for lights, registers, fire sprinkler heads, smoke detectors, exit signs, etc. as required. 7. All models should include separate 3D representations of required clearances and/or access requirements for equipment access, light clearances, overhead cable tray access, etc. These clearance/access 23

26 models should be in a separate layer(s) for each trade clearly labeled as such. 8. The granularity of elements in the model has to correspond with the sequence of the installation at the site (e.g. not one wall element for the entire floor). 9. All 3D model files submitted for clash detection must be clean with any extraneous 2D references and/or 3d elements stripped from the models. 10. Once a conflict or discrepancy has been sufficiently resolved, the Construction VDC Manager (and Design BIM Facilitator, as required) will update all related models, model views, and clash reports to reflect these changes. Contractor may be required to implement revisions / solutions in a revised model and re-submit. 11. When ing notification of file uploads or for any other correspondence pertaining to this project, all subject line headings must be prefaced with the acronym for the Project Name. 12. For ease of identification during the 3D Coordination process, the following trades will be represented in these assigned colors: Trade colors for Coordination Software Fire Protection: red - RGB: 255, 0, 0 Plumbing: magenta - RGB: 255, 0, 255 HVAC Duct: blue - RGB: 0, 0, 255 HVAC Pipe: lime green - RGB: 0, 255, 0 Electrical: cyan - RGB: 0, 255, 255 Pneumatic Tube: dark green - RGB: 0, 76, 0 Concrete: gray - RGB: 128, 128, 128 Structural Steel: maroon - RGB: 127, 0, 0 Architectural: white - RGB: 255, 255, 255 Security: pink - RGB: 255, 127, 255 AV: orange - RGB: 255, 62, 0 Low Voltage: brown - RGB: 127, 63, 0 Fire Alarm: purple - RGB: 102, 0, 204 Specialty: User Defined (provide RGB settings for approval) * Additional trades or systems that may be required shall be identified in the BIM Execution Plan(s) and designated a color to be used for coordination for the duration of the project. 24

27 3.2.6 Collaboration in the Installation Planning Process During shop drawing preparation phase. To optimize field installation, the Construction VDC Manager will coordinate with affected trade sub-contractors to coordinate locations for proposed installation of systems within the coordinated spatial model. Subcontractors will be expected to have individuals attend who can actively engage in the planning process, and be capable of addressing and resolving conflicts and the cost/schedule implications they may have. Prior to installation, the Construction VDC Manager will conduct installation meetings with affected trade sub-contractors using the coordinated spatial model. Contractor shall be required to participate in regular coordination meetings with all other parties participating in the BIM efforts to review conflicts and clash reports, and to jointly develop solutions for spatial conflicts. Contractor shall include the CPT/PMO team at coordination meetings, as needed or at the request of the CPT/PMO team. Necessary rerouting shall be agreed to by the CPT/PMO team and the Design Team Digital Fabrication Digital Fabrication allows for more accurate and efficient installation in the field, but requires a more collaborative effort between designer, builder, and tradesmen to ensure that the deep knowledge and associated efficiencies of the fabricator are embedded into the construction model. See Section and for additional fabrication definition. As part of the contractor s submittal for each, the following construction trades shall provide 3D fabrication models with 3D model objects: 1. Mechanical System Ducting 2. Plumbing Systems and Piping (excluding Plumbing Fixtures) 3. Electrical Conduits 4. Curtain Wall systems 5. Building Envelope Systems (i.e. rain screens, pre-cast panels) 6. Casework and furniture systems (furniture vendor models must be used when available) 7. Fire Sprinklers (excluding FP equipment) 8. Any additional fabrication models generated by subcontractor Coordination of entire building The Contractor s VDC Manager will assemble a composite model from all of the model parts of each design discipline for the purpose of performing a visual check of the building design for spatial and system coordination. Vertical shafts should also be reviewed to ensure that adequate space has been allocated for all of the vertical mechanical systems and that all of the shafts line up floor to floor. 1. Coordination, floor by floor On larger multistory project, the models may be split on a level by level basis for trade coordination. If a floor is particularly large, it may also be split by 25

28 zones to reduce file size. In such cases, each floor shall be created as a separate level in the coordination software, and all trades shall reference a shared and documented insertion point and methodology for developing these files. Typically, 3D coordination starts at one floor until building systems are fully coordinated on the floor, and then continues on to the next floor up Clash detection and reporting 1. Coordination software will be used for assembling the various design models and for providing a report and view list of design coordination issues. The Design Team, including Design BIM Facilitator and Discipline BIM Lead Modelers, will review the model and the Clash Reports in coordination meetings on a regular (weekly) basis. 2. The report will be reviewed by the team members and agreed upon solutions will be implemented per an agreed upon schedule. This process will be repeated throughout the design phases until all spatial and system coordination issues have been resolved. 3. During the construction phase, the Contractor shall utilize the fully coordinated and consolidated design BIM to verify the accuracy of certain fabrication models (ref. Sec 3.2.7). Prior to each fabrication submittal for approval, fabrication contractors shall submit their models to the Contractor s VDC Manager for integration with the Design Model. 4. Internal Clash Resolution Design Consultants and Subcontractors who are responsible for multiple scopes of work are expected to coordinate the clashes between those scopes prior to providing those model to the VDC Manager for spatial and system coordination. 3.3 Project BIM Work Plans (BIM Execution Plans) Design and Construction teams shall be required to submit to LACCD for approval, a Design BIM Execution Plan and Construction BIM Execution Plan demonstrating a strategy for using Building Information Modeling to execute project deliverables. 26

INTRODUCTION The purpose of the Quality Assurance and Validation process is to ensure project teams are using Best Practices in the development and file exchange of building information models. Quality Assurance is an ongoing process to be conducted by the Project Team and validated by the College Project Manager at both project milestones and random intervals of the project to ensure that each BIM is being constructed in conformance with LACCD BIM Standards and is suitably modeled for its intended use. The goal is to detect and correct, any errors and deficiencies in the models early in the process such that these discrepancies to not result in unresolved issues during construction or any significant loss of data upon transfer of as-built models and record documents to the District for Operations and Maintenance use QUALITY ASSURANCE CHECKLISTS LACCD has developed a series of checklists to assist project teams and College Project Managers with the quality assurance and validation of project building information models. During Design, it shall be the Design Team s responsibility to submit completed copies of the DES-002 B ProjectWise Upload / Validation Report and BIM Standards Validation Report at each project milestone in conjunction with project deliverables. DES-002 B is a Report deliverable based upon the BIM Quality Assurance and Validation Checklist. During Construction, the DES-002 B ProjectWise Upload / Validation Report and BIM Standards Validation Report will be maintained and updated by the Design Team and Construction Team and submitted to LACCD in concert with Construction update submission checks. It shall be the responsibility of the College Project Team to validate the quality of the models submitted to ensure they are in compliance with Best Practices and LACCD BIM Standards referenced on the completed checklists as follows: 1. Develop and maintain a detailed BIM Work Plan for LACCD approval prior to Notice to Proceed 30

33 2. Develop and Maintain Information Delivery Manual during design and construction phase with final IDM submitted per Document Submission Standards 3. Verification and updates of assigned roles and responsibilities as documented in RFP and maintained throughout Design and Construction Process 4. BIM Quality Assurance and Validation Checklist - The BIM Quality Assurance and Validation Checklist is a step-by-step checklist to ensure Projects are conforming to LACCD BIM Standards and use best practices in the development and exchange of building information models. The checklist references specific sections of the LACCD BIMS, and shall be used as a tool to understand the requirements of the models at each project milestone. For each trade, the trade s Lead BIM Technician shall coordinate with the Design BIM Facilitator and/or Construction VDC Manager to verify their respective section of the checklist at each project milestone. Any major discrepancies or conflicts should be resolved prior to submission to LACCD. 4.3 Model Based Reviews At each project Design milestone defined in the Document Submission Standards, the Design Team shall prepare and make available to LACCD a coordinated model to be used for model based reviews. During Design Development, Project Teams may be asked to utilize perspective and walkthrough capabilities of the model with user groups, Facilities Directors, and other campus stakeholders to track design issues visible in the model. Prior to submittal to DSA Submittal, Project Teams may be asked to schedule a virtual building walkthrough with CPTs, Facilities Managers, and LACCD BIM Technical Staff using the coordinated design model to demonstrate design, coordination, and equipment access issues have been fully resolved and meet Owner Program Requirements and Basis of Design. 31

36 APPENDIX - Technical Footnotes & Diagrams a. Finding the Revit Origin Finding the Revit Origin and Guidelines for Sharing Coordinates of an existing site file in Autodesk Revit Revit does have an origin but it is hidden by default. LACCD can provide Campus Survey Civil CAD files to the teams. The files contain the Campus property line, as well as survey points representing Campus Monuments. The survey s specific coordinate points should be linked Origin to Origin to the main Architecture Revit file. To do this: Link the Civil CAD file provided by LACCD into the Architecture Revit file. In the Architecture Revit file, unclip the Project Base point and the Survey Point. Move the Survey Point in the Architecture Revit file to match Survey Point located in the linked Civil file. Set the Building Project Base point to 0,0,0 Pin both points (survey point and Project Base point) into the Architecture Revit file, and always use the command Collaboration to monitor the survey point located in the Civil file. When setting the project base point (once a few walls are in place), make sure to modify the True North view to be the Project North view. The LACCD Campus Survey Civil CAD files are located in the Campus Information folder (for each campus) in ProjectWise in the Campus Siteplans, Site Utilities, Site Surveys, etc sub-folder: b. Not used c. Suggested File Setup - for Construction As-Built and Record As-Built BIM Submissions For As-Built submissions, LACCD recommends creating 2 separate Revit files for the Architectural Model, and possibly (depending on size and complexity of the project) creating 2 separate Revit files for each of the Trade s files: BIM Asset file: Contains the true solid 3D model and all M&O Asset data BIM Plot file: Contains all annotations, Dims, general notes, detailed views and title sheets. Is used as a tool to plot sheets and create Construction documents and deliverables. These files can be built off of the template files defined in: APPENDIX - Technical Footnotes & Diagrams, item e: The BIM Asset file should be created from the LACCD_ASSET template The BIM Plot file should be created from LACCD_PLOT template The benefits of working with two files (BIM Asset & BIM Plot) file vs. one single file: Reduced file size of Revit files Reduction of work sets More flexibility to have more than one BIM user to produce documents Clean, light, user-friendly files that include only the true model(s) while all information Sheets and notes are not interfering with the constructability of the model 34

37 d. Link Management Strategy - for Construction As-Built and Record As-Built BIM Submissions This Diagram represents the suggested strategy of linking BIM files if two Architectural Revit files are used as described in item c of this Appendix. Note: the only file linked to the Arch Plot file is the Arch. BIM Asset file. Arch. BIM Plot MEP BIM AV BIM Fire Protection BIM Arch. BIM Asset Security BIM Structure BIM Fire Alarm BIM e. LACCD Revit template files LACCD provides two Revit project template files for teams: LACCD_PLOT: This template file includes all LACCD Annotation Standards, Dim Styles, Fonts, Legends, Object Style, Title Blocks, Tags and all other Aesthetical Standards. Use of this template ensures functionality and aesthetical consistency among all projects and campuses. LACCD_ASSET: This template file ensures consistency in Family Parameters to satisfy Metadata requirements per LACCD BIM Standards and Form DES-0002D: BIM Asset Data for Design and As-Built Documentation.Use of this template helps teams to more easily define the Asset Data which is required for model objects. It also contains more than 60 schedules linked to those model objects to help teams (and reviewers) more easily identify if asset data is in compliance or is missing within their model. The LACCD Revit template files are available at any time during the design or construction of the project, but it is suggested that the teams use the templates early in design. The LACCD_ASSET template will also greatly aid in the verification of the tagging of model objects (using the keynote parameter). A list of the keynotes associated with each model object is found in form DES-0002-D BIM Asset Data for Design and As-Built Documentation - New Construction and Renovation. The Template files come in two versions: LACCD Revit Template Files R16 (for teams using Revit 2016) LACCD Revit Template Files R14 (for teams using Revit 2014) Why two templates? As Stated above, each template is created for a specific task. Although it is simple to combine both templates and create a single BIM template file, LACCD recommends keeping them separate. As noted in APPENDIX - Technical Footnotes & Diagrams, item c: a BIM Asset file should be created from the LACCD_ASSET template and a BIM Plot file should be created from LACCD_PLOT template. 35

38 f. Keynote Assignments for Elements The addition object keynotes (following the LACCD structure) is strongly encouraged to enable automatic filtering of objects when using the LACCD_ASSET Template. This is done by the assignment of a code into an object s keynote parameter (found in an object s Type Properties). A list of keynote codes to assign to each object type is found in form DES-0002-D BIM Asset Data for Design and As-Built Documentation - New Construction and Renovation. Once the keynotes are added, the pre-made schedules in the LACCD_ASSET Template will automatically populate with any user-entered object data specific to the LACCD requirement. This will greatly aid in the verification of the data required within those model objects. An example of why this should be used Mechanical Equipment In a Mechanical Revit Model, the majority of HVAC equipment is scheduled in the Mechanical Equipment Schedule. However, based on the LACCD Standards, the asset data required for this equipment (defined in form DES-0002-D) varies element-by-element. Creating just one schedule for all mechanical equipment elements would make verification of the asset data extremely difficult. The better way is to break up the mechanical equipment elements based on their asset requirements. Adding keynotes and using the LACCD_ASSET Template automates this process. How to setup Keynotes and assign them to object types: 1. Specify the correct Category for the element. Never use generic models. If you are unsure of the correct category for an element, refer to form DES-0002-D. Look in the column titled Category. 2. Locate the correct Keynote code for the element. Keynote codes can be found: a. In the Schedule Properties of the corresponding pre-made schedule found in the BIM template - look in the Filter Tab within the Schedule Properties. b. In the form DES-0002-D BIM Asset Data for Design and As-Built Documentation - New Construction and Renovation - look in the column titled Keynote. 3. Once the code is found, enter that code into the Keynote Parameter field found in the Type Properties of your element. See the example of the Keynote Code for a Door (ARDOR) below: 36
