The Clemson University Site Design Guidelines outlines the design principles and design guidelines that must be followed regarding the exterior appearance qualities of facilities at Clemson, and how these qualities reinforce the unity and identity of individual districts and nodes of the campus.Exceptions to these guidelines must be approved by the Director of University Planning and the Chief Facilities Officer.
For renovations and additions to historic structures, mortar materials, colors, and joint profiles are critical and careful attention must be given to their effects on the construction and renovation of these facilities. Hence, for repairs to the existing masonry on some historic structures, it is important to pay special attention to the selection of mortar materials, since the use of some mortars presently available may result in the strength of the mortar exceeding the strength of the brick.
Brick Selection and Sample Panels In order to assure the best possible selection of brick, mortar, and proposed jointing for the project, specify that the Contractor shall prepare sample panels (from samples recommended by the A/E) of all proposed exterior materials from which a selection can be made. Coordinate the size, form and location of these sample panels with the Project Manager. Coordinate the selection of masonry with the selection of other exterior materials at the same time, i.e., roofing, metal work, other building trim.
After the selection has been made, coordinate the construction of an additional sample panel of the approved material to show in detail the variety of shapes, coursing, etc. that will be used in the facility. Maintain this enhanced sample panel until completion of the facility for comparison and standard of quality for the building.
For most projects, specify a cash allowance for the purchase of brick for the project. Coordinate any exception to this requirement with the Project Manager. Specify that all exterior face brick is to be purchased at one time and delivered in sufficient quantity to complete the installation, so as to assure a uniform color throughout the building. Indicate a brick storage area on the documents after coordination with the Project Manager.
The University prefers that masonry joints be of the type that will inhibit the entrance of water into the building. This makes “tooled” joints the joint of preference. Some design conditions may dictate departure from this preference, i.e., additions to existing buildings and project location. Any departure from the use of “tooled” joints shall have prior approval, in writing, from the Project Manager. The use of colored mortar is strongly discouraged on the campus and its use also requires approval, in writing, from the Project Manager.
Adequately specify methods for cleaning the various types of masonry used in the facility and any extraordinary conditions that may affect the use of masonry cleaning materials and equipment. Prohibit the use of sandblasting as a method for cleaning masonry.
Because of long term maintenance requirements, the widespread use of water-repellent masonry coatings is generally discouraged. The effective use of design detail must be utilized to minimize and/or inhibit the entrance of water into the structure.
Walkways and pedestrian circulation is discussed in the Clemson University Site Design Guidelines and must be reviewed when selecting paving material for walkways on the campus. The brick that is in general use for brick paved areas on the campus is solid paver in the red-brown range. Consult with the Project Manager concerning the selection and use of brick pavers on the project.
All masonry design shall comply in entirety to the most restrictive interpretation of applicable codes. Special attention must be given to all seismic requirements for construction in this seismic zone.<
Selection of coursing of exposed concrete masonry unit walls must be coordinated with the Project Manager.
The use of stone masonry may be acceptable as a construction material on some exterior walls or other site installations. Its use is generally discouraged as a building material on the facility proper. Consult with the Project Manager for the possible use of stone masonry on campus.
