Construction Project Summary
Upon recent inspection of the Very High Frequency (VHF) radio site, it was evident that the roof requires repairs in order to extend the life span of the building. The roof structure is built from steel beams with a roof framing slope of 2:12. A total of 240 90mm x 610mm x 610mm (weigh approximately 90lbs each) concrete blocks are placed on the roof membrane to avoid damage from high winds.
Work for this project consists of replacing the existing roof membrane. This will be done in sections by relocating the current concrete blocks to another section of the roof to expose the existing torch on membrane. The existing membrane will be removed, as well as the fiberboard underneath. New fiberboard will then be installed as required. The roof eve is to be built out an additional 75mm all around the perimeter of the roof. New 0.64mm pre-finished metal flashing to be installed.
170N geotextile will be installed on top of the new ethylene propylene diene terpolymer (EPDM) membrane. Once secured, the concrete blocks will be placed back on top of the geotextile. Note: Concrete blocks will not be replaced as the proper equipment to remove and replace new concrete blocks is not able to access the site. The road has become inaccessible to trucks and larger equipment.
The work included in this contract is specified in the format of general specification document with specific works identified on drawings. The contractor remains responsible for the appropriation of the work between the trade, contractors, his own forces and suppliers. The Engineer will not be responsible for determination of or for providing opinion on the scope of work split between sub-contractors and trade jurisdictions.
