Amendment 02 REVISED SOW - REPAIR ROOFS 29 MAR 23.pdf

STATEMENT OF WORK - Revised Project Number VBDZ232100

Repair Roofs

DESCRIPTION:

Roofs on seven facilities are to be repaired per UFC 3-110-03 Roofing. The UFC can be obtained on the following website: https://www.wbdg.org. The EPDM roofs require reattachment of the membrane and patching of holes. Bitumen roofs need patching and sealing. Metal roofs need fastener replacement and elastomeric coating. All roof area measurements are approximate and shall be field verified by the contractor during the site visit, prior to offering a price estimate.

Contractor may propose alternative solutions to the below scope prior to the award. Please provide the pricing for each of the Option items separately. Not all options may be awarded. With exception of Building 20, none of the buildings are leaking. After the discoveries during the site visit, the scope has been adjusted by removing the Bldg1 and Bldg 26 from the project.
