SECTION B – SUPPLIES OR SERVICES AND PRICE/COST

B.1 OBJECTIVE:

The District of Columbia Courts (the Courts) Procurement and Contracts Branch on behalf

of the Capital Projects and Facilities Management Division (CPFMD) is seeking a qualified

contractor to perform roof destructive testing services of the flat roofs located at Building A

(BLDA) and Building B (BLDB) of the Courts Judiciary Square Campus.

BLDA, which houses the DC Superior Courts Probate Division is located at 515 5th St NW,

Washington DC 20001. BLDB, which houses the DC Courts Landlord and Tenant Branch

is located at 510 4th St NW, Washington DC 20001.

The Courts estimates both the low slope single-ply PVC portions of the roof to now be

approximately 20 years old, and at the end of their lifespans. Several band-aids have had to

be done over the past few years, involving patch repairs to the membrane, flashing, and

drains. There is also significant leaking in the skylights for BLDA. The low slope “flat”

single-ply PVC roofing has deteriorated significantly for both buildings, compared to the

sloped copper standing seam roof.

An Architect/Engineer (A/E) firm is currently performing the design to develop 100%

construction documents to replace the flat roof portions of both roofs.

The purpose of this work is to provide controlled access to the roof assembly and concrete

roof structure to support evaluation activities performed by the A/E. Work will include roof

test openings, ground penetrating radar (GPR) scanning of the exposed concrete roof slab,

take roof cores, review of the flashing assembly where the flat roof meets the copper roof,

and restoration of roof openings.

B.2 CONTRACT TYPE:

The Courts contemplates award of a single Firm Fixed Contract.

B.3 PERIOD OF PERFORMACE:

The period of performance (POP) shall be sixty (60) calendar days from the Notice to

Proceed (NTP).

by CSI division as specified in Attachment C - Schedule K.
