GOC375653, Roof Replacement - West 1993 Roof:
Replacement of the west roof section over the addition constructed in 1993.  This is a built up roof - pea gravel over 4-ply BUR over insulation, vapor retarder and metal deck and comprises approximately 3,178 Sq. Ft.  See the attached Roofing Assessment Report completed in July 2014.  Repair all flashings.  It will be necessary to lift HVAC equipment so an allowance for a mechanical contractor will be required of the building as it is at the end of its effective service life.  Roofing dates from 1993 and given its age, current condition and previous leakage is considered to have exceeded its effective service and requires replacement.  Plans and specs year one and implement in year two.  Complete the construction work in fair weather, preferably in the Spring.
