3 DESIGN GUIDELINES I. Introduction A. Design Intent 1. Miami University has over the years developed a vocabulary of building and landscape which has come to be strongly identified with this educational experience. Brick structures, predominately of a Georgian style, organized into quadrangles, has been the image of the school from its early history. It is intended that this be continued. In keeping with the Americans with Disabilities Act of 1990, all buildings, spaces and parking shall be designed to meet or exceed these Federal Standards. The inventory of mature trees, that canopy walks and green areas, are strongly associated with the Miami campus. It is anticipated that each new structure added to the setting will include a landscape plan which will complement the structure as well as the existing campus pattern. II. III. Concurrently, as new technologies are tested and available, particularly those dealing with energy conservation and recycling, they should be considered for implementation into the campus environment. The design intent extends also to the budget of the project. It is expected and required that the project be designed and delivered within the funds available. Architecture A. Each new structure must be a worthy contribution to the inventory of buildings on the campus of Miami University. Buildings are expected to a modified Georgian style where possible. Belden Berwick Blend brick with vine mortar joint, has been selected as the masonry and joint of choice, with caps, lintels, and other ornament in limestone. Within this palette, it is expected that the design will respected the pedestrian scale of the campus, acknowledge existing circulation patterns and massing, and to complement the existing campus fabric. Functionally, it must address and accommodate the given program in a satisfying and intellectually stimulating manner. B. Maintenance 1. All systems, spaces, materials, shall be designed for proper, efficient, and economical maintenance. Materials and finishes are selected to withstand University activities over the life of the building. Miami University believes that in most cases, initial investment in quality material, construction, and installation will prove economical over the life of the project. All systems are to be accessible, serviceable, and maintainable. Durability and ease of maintenance is a major consideration in the design of additional building stock. C. Design Process 1. The Associate is required to involve the University in the development of building exteriors and adjacent appurtenances by conferring with the University Architect/Engineer during development of preliminary plans. Furnish a number of elevation studies for review. The submission of detailed elevations without prior review may result in rejection of the entire preliminary submittal and require complete redesign. Site Planning and the Landscape A. The selection and planning of the site including the building orientation, layout, and parking are of prime importance in the integration of the building into the campus fabric. Trees,

4 especially healthy and mature specimen are highly valued on the campus, and should be carefully protected and celebrated. The alignment of drives, facades, and continuity of spaces are some factors in creating continuity of the campus. B. Maintenance 1. Exterior space must be designed with concern for maintenance. Snow removal, lawn mowing and leaf removal should be accommodated when specifying paved areas, materials, slopes, and widths of lawn areas. C. Design Process 1. The Architect/Engineer shall visit the site and evaluate proposed locations of the project and shall discuss problems related to siting with University officials before beginning design. The employment of a professional Landscape Architect is expected, particularly where the structure affects open space or there exists a complex set of site issues. The Architect/Engineer is encouraged to generate alternative design concepts from those based strictly on the Program of Requirements, if site conditions indicated that other arrangements are merited. Consultation and final determination with University personnel is required. Integration with the campus master plans through field surveys and measurements must occur. The Associate is responsible for the accuracy of information shown on the contract drawings. Note: The associate responsible for Electrical Design shall, as part of the design, incorporate an ARC Fault Study and labeling of electrical equipment with Arc Flash Hazard Warning & Maximum Available Fault Current labels as mandated in the National Electric Code, Article and IV. Structural Systems A. Structural systems must be designed to provide ease, economy and structural integrity. Any non-conventional structural system should be approved by the University Architect/Engineer early in the schematic design phase. Technical innovation and the inevitable modifications in curriculum requires flexibility in building spaces. Interior floors and wall systems should be designed to accommodate change. B.

Preferred Systems i. Wet systems generally used- dry pipe systems should be used in areas subject to freezing ii. Alternate systems: in areas where water damage to furnishing and equipment necessitate alternate systems, one of the following should be considered, potentially requiring code variances: a) Pre-action suppression system b) Carbon dioxide based system c) Halon substitutes (Intergen FM-200) d) More restrictive fire separation iii.

Circuits from the primary switching station to feed multiple buildings through pad mounted and manhole mounted high voltage systems. Some circuits are looped for reliability 3. Substations are generally located inside in their own room. For buildings having major motor loads, a 460 volt 3 phase system will be installed together with a 208 volt, 3 phase 4-wire system for lighting and power distribution 4. In buildings with smaller loads, a single 208 volt, 3 phased, 4-wire system may be installed 5. A consumption meter together with a demand meter shall be installed in each substation. In substations with two transformers, means will be provided within the station so that one transformer can be worked on while the other remains in operation 6.
