600 E. 4th Street Renovation

The Wilmington Housing Authority (WHA) in Delaware is soliciting sealed bids through an Invitation for Bids (IFB No. B26002) for a comprehensive roof renovation project at 600 E. 4th Street in Wilmington. The procurement seeks qualified, licensed, and insured vendors to execute extensive roofing work across two distinct roof sections (Roofs 01-08 and Roofs 09-12), including removal of existing granular surfaced modified bitumen and built-up roofing membranes, assessment and removal of asbestos-containing materials where identified, structural repairs to lightweight insulating concrete slabs and metal deck substrates, and installation of new insulated modified bitumen roofing systems with complete vapor barriers, insulation, tapered crickets, cover boards, and flashings. The scope of work additionally requires removal and replacement of all sheet metal flashings, trim, coping, through-wall scuppers, and roof drains, as well as disconnection, removal, reinstallation, and reconnection of existing rooftop mechanical units on replacement curbs and rails to achieve a minimum 12-inch high base flashing. Bidders must submit proposals via the Bonfire (Euna) online procurement portal with a mandatory pre-bid conference and site visit scheduled for April 9, 2026, at 10:00 AM at 321 E. 11th Street, Wilmington, Delaware 19808; written questions must be submitted by April 14, 2026, at 12:00 PM; Intent to Bid is due April 23, 2026, at 10:00 AM; and final bid submissions are due April 23, 2026, at 12:00 PM. The contract period is anticipated to be 120 days from Notice to Proceed with no renewal option, and all proposed fees must be all-inclusive of labor, materials, equipment, insurance, licensing, tools, and other costs necessary to complete the work in compliance with applicable building codes. Successful bidders must provide proof of workers' compensation insurance, general liability insurance of at least $1,000,000 per claim, automobile insurance of $1,000,000 combined single limit, applicable business licenses, and a bid bond equal to 10 percent of the bid amount.

This procurement does not specify particular set-aside designations or restrictions limiting bid participation to specific enterprise categories, though bidders are required to complete representations and certifications addressing Section 3 business preferences, debarment status, and other compliance requirements as part of the standard HUD Form 5369-A bidding process. No incumbent vendors or current contractors are identified in the solicitation materials. A $19,000 contingency fund will be set aside by the WHA for unforeseen conditions identified during construction, and labor rates may escalate at the end of the first contract year based on increases in Delaware Prevailing Wage Rates, subject to the Contracting Officer's discretion and the contractor's written request submitted at least 60 days before contract expiration. The contractor must comply with HUD Maintenance Wage Rate Determinations and Delaware prevailing wage requirements as established in the applicable wage decision documentation. While no explicit total contract value is stated, the comprehensive nature of the project involving multiple roof sections, hazardous material handling, extensive system replacements, and mechanical unit repositioning indicates a significant capital investment estimated in the mid-to-high six-figure range. The WHA reserves the right to reject any or all bids, award to multiple contractors based on lowest responsive and responsible bids, and terminate contracts for convenience with 10 days' written notice.
