RFI Question Answer

17 Is the sallyport garage ceiling solid concrete? Are there any drawings, details, or sections of this area?

The existing structure consists of a steel framing system with a concrete slab.

Details are shown on Sheet AE502. As-built drawing S5.1 (included in Amendment 0002) includes Garage Plan Sections and Details.

As per specification 011000-1.2-A-a, removal of existing metal roofing and existing plywood substrate down to existing steel purlins as required by structural calculations shown on the contract drawings as indicated on drawings. Design team structural calculations could not be found in the drawings.

Please advise.

Based on the structural wind calculations it was determined during design that additional purlins are required to be installed at 1’-0” on center between the existing purlins. The areas where this is required are shown as light gray shading on detail B / sheet S100. At the high roof there is a region designated by a crosshatch pattern where the new purlins are to be doubled members at 1’ -0” on center due to the long span. These areas represent all the sloped portions of the roof.

To install the new purlins, it is required to remove 100% of the metal roofing and plywood sheathing from these areas. Installation of the new purlins and sheathing shall be in accordance with the details on sheet S-100.

The flat portions of the roof are not shaded or hatched on B / sheet S100 and are understood to be concrete and/or metal deck that does not require structural work other than incidental infill of old openings as described in the bid options.

Please provide the information of the existing mechanical / electrical / communications equipment and conduits located in the existing roof.
