Description

The Coastal Bend Bays & Estuaries Program (CBBEP) is seeking sealed bids for the reconstruction of berms on Matagorda Island, part of the Aransas National Wildlife Refuge. The work includes: • Restoring two breached berm sections and removing damaged material. • Installing new 36‑inch HDPE culverts and related components. • Placing riprap for shoreline protection. • Improving access roads. Owner‑furnished sand, graded riprap, and other construction materials will be provided on‑site. Bids are to be submitted via U.S. Postal Service or hand/express mail to HDR Engineering by 2:00 p.m. on 18 Sep 2026. A non‑mandatory virtual pre‑bid conference is scheduled for 27 Aug 2026, and a site visit is offered on 28 Aug 2026 at the refuge headquarters. Questions must be emailed to HDR’s Julie Morris by 5:00 p.m. on 11 Sep 2026. Digital bid packages are free; printed copies incur a $75 fee (additional $25 for full‑size plans).

Budget estimate

$1,200,000 – $1,600,000

The solicitation lists a contract value of $1,500,000. Based on typical civil‑engineering construction costs for berm reconstruction, HDPE culvert installation, and riprap work, the final award could reasonably range from roughly $1.2 M (if scope is minimized) to $1.6 M (if additional site‑specific challenges arise). Factors influencing the final amount include material mobilization costs, subcontractor rates, and any unforeseen environmental mitigation requirements.
