DELIVERY, STORAGE, AND HANDLING
1.5.1
Delivery
**************************************************************************
NOTE: Include bracketed requirement when hot-mopped
membranes are used or base sheets are hot-mopped to
non-nailable substrates.
**************************************************************************
Deliver materials in manufacturers' original unopened containers and rolls
with labels intact and legible. Mark and remove wet or damaged materials
from the site. Where materials are covered by a referenced specification,
the container shall bear the specification number, type, and class, as
applicable. [Labels or bill of lading for roofing asphalt shall indicate
asphalt type, FP, FBT, and EVT, that is, the temperature at which the
viscosity is either 125 centistokes when tested in accordance with ASTM D
2170 or 75 centipoise when tested in accordance with ASTM D 4402.] Deliver
materials in sufficient quantity to allow work to proceed without
interruption.
1.5.2
Storage
Protect materials against moisture absorption and contamination or other
damage. Avoid crushing or crinkling of roll materials. Store roll
materials on end on clean raised platforms or pallets one level high in dry
locations with adequate ventilation, such as an enclosed building or closed
trailer. Do not store roll materials in buildings under construction until
concrete, mortar, and plaster work is finished and dry. Maintain roll
materials at temperatures above 10 degrees C (50 degrees F) for 24 hours
immediately before application. Do not store materials outdoors unless
approved by the Contracting Officer. Completely cover felts stored
outdoors, on and off roof, with waterproof canvas protective covering. Do
not use polyethylene sheet as a covering. Tie covering securely to pallets
to make completely weatherproof and yet provide sufficient ventilation to
prevent condensation. Do not store more materials on roof than can be
installed the same day and remove unused materials at end of each days
work. Distribute materials temporarily stored on roof to stay within live
load limits of the roof construction. Immediately remove wet, contaminated
or otherwise damaged or unsuitable materials from the site. Damaged
materials may be marked by the Contracting Officer.
