3 1. Introduction CALS/EC has been promoted for 17 years since 1996 by MLIT and JACIC. Electronic delivery couldn t catch up with ICT and social environment. And systems were tied up in many strict standards, and each phase became independent, and an information sharing was not possible. CIM was aimed at IPD and IFC model of the thought of BIM as innovation of a new construction production system in 2011 by MLIT. Pilot implementation began as kickoff by JACIC seminar in MLIT had 11 trials of the design projects in In 2013, seven cases are going to be tried as a construction project. 3

4 Recommendation of CIM For the innovation of the construction production system. November 11, April 13, A) In construction site, we mobilize all the ICT such as 3D models and carry out model construction. B) we circulate by data for the idea from maintenance. C) Each engineer reforms consciousness and uses the ICT forward. Sato, Vice-Minister for Engineering Affairs, MLIT (At the time of 2012). 4

5 2. Method of Concurrently shared product model Conditions and resource, environment 1) Conditions a. Utilization scene is clarified, and it is a main premise to be the useful model. b. Not a model to make in the short term, but in the long term is necessary. 2) Viewpoint We must pay attention to PM, QCDSE, PDQ, SCM/DCM, risk and finance. Work flow a. BIM related information collection b. IPD, understanding of BIM, inspection c. IPD, quotation We are divided into two of the next specifically in the long term. 5

6 2. Method of Concurrently shared product model Point of view In conformity with IPD, project management need a communication tool supporting knowledge management. In addition, it is important to cooperate keeping the relations and take load for a previous phase. Therefore, we would perform the risk management of the project appropriately. It is possible to prevent rework because actual operation contractor makes a construction plan with a designer from the early time. Based on these factors, we can shorten term of works and reduce cost and improve quality, and accomplish improvement of the productivity. Here is that CIM learns from BIM. However, BIM is only a tool of 6 IPD.

7 2. Method of Concurrently shared product model I. Short term correspondence (Trial construction) It s important to make 3D model early, and also make useful educational system. At first approach from seeds-oriented is realistic. Proof procedure is as follows. 1 For the first phase, making a compatibility map every business processes 2 The plural presentation by the same process 3 Trial, and proof 4 Effect inspection 5 Optimization of the process 6 Compatibility confirmation between processes 7 Extraction, rearranging of effect inspection and the problem 8Sophistication 9Phase optimization Making of the model making procedure book Confirmation of the conventional modeling technique. Extraction of the point promoting efficiency of 3-D modeling Rebuilding of the modeling procedure The template of the units and parts. Model construction technique /CAD use rule Skill up education, training Result confirmation and market activation Examination of the simplification program 7

8 2. Method of Concurrently shared product model II. Medium-and-long term correspondence We plan a three-dimensional shape model, unified DB based on an international standardization, the CIM base model corresponding to the compatibility of the common ground concerned every medium-and-long term for domain. examination procedure is as follows. 1 Rearranging, examination of data models such as BIM 2 Construction sector (Kind of construction; Domain) 3 Setting of the profit utilization scene, effect assumption 4 PM element about each model are risk, process, multiplication, simulation 5 Development of a concept, the outside, and the internal schema 6 Development of each data model, and unification 7 Construction (unification of each base) of the general country base 8 Examination and maintenance of the light and shade model What we plan teaming including orderer designer, actual contractor and supplier in an early stage, we can disperse the risk of the defects by learning IPD of AIA. 8

10 2. Method of Concurrently shared product model Method by being structured of collection, accumulation, analysis, utilization On the common infrastructure, platform, concurrent processing and parallel processing which exchange of plural work shares largecapacity (Volume) (Variety) of Big Data by high-speed processing in real-time (Velocity). A. Unified Modeling CIM DB We suggest information service about CIM in JACIC. B. CIM Integrated Database The CIM server which will be the platform of the CIM model assumes non-structure data a basic database, and the non-structure data include structure data. About LCC (life-cycle Cost) of data, we consider TCO (Total Cost Ownership) from outbreak to the disposal. Figure is a plan of the images of the CIM unification database. 10

12 2. Method of Concurrently shared product model 2.2 CIM model structure The technical problem rearranging in the CIM model In the case of integration and the visualization of the 3D structure, we unify each part model with the 3D model adding unification with the attribute information. As an image of based on knowledge management and show structural figure that place" holding information sharing and a multidimensional model a nucleus Figure.

13 2. Method of Concurrently shared product model Fusion with existing data and new data, structure of being structured and nonstructured model We let various forms and old and new data fuse as Big Data on a precision and particle size. Properties of matter, an attribute: Multiplication (amount calculation), simulation A process model, difference in construction plan amount calculation technique, quantity of soil coordinates method average section method voccel model, surface model The use in various scenes where a design leads to construction, maintenance, a plan (newly), update Geometry shape information (x, y, z:) Three-dimensional) + time (Time, delivery:) The concurrent use of process, five dimensions of procurement speed) + cost (multiplication, the volume) = models, attribute information (materials), process, process, geography space, role information, mutual related information structure information aggregate PDM for the purpose of the steel materials placement management and digital image superimpose; use of the elemental technology, VR, AR, TUI (Tangible 13 User Interface)

14 2. Method of Concurrently shared product model 2.3 Each domain model, common resource Unification on the three-dimensional platform Effectiveness and the problem of Infrastructure Modeler soft on the three-dimensional platform Cooperation We unified models from plural data sources and perform confirmation and a plan of the application procedure Maintenance Using an intelligent industry model, we maintain more reliable attribute information. 14

15 3. RESULTS We investigated element data and attribute item on specification of both model and software to confirm validity of the precision of model. From these findings we found out that software with double precision of the input and output and calculation columns was most. We show rearranging of the data precision in Table.

16 3. RESULTS LOD plan in civil Based on these results, we arranged the indication to road crosssection data and alignment data exchange standard, and examined item of specifications and guidelines, and arranged it as LOD. Depending on a use, it is necessary to raise data precision than LOD3. In addition, it is necessary to display precision quality about the LOD of three-dimensional data. As LOD for CIM in lifecycle infrastructure model, Figure is shown. 16
