Statement of Work for DCMR Ramp Improvement Project

The U.S. Embassy in Bangui is soliciting bids for a ramp improvement project at the Deputy Chief of Mission Residence, requiring a fixed price lump sum proposal from qualified contractors with at least five years of construction experience and three verifiable references for similar concrete placement work. The scope includes replacing the existing driveway surface with a 15cm thick wire-reinforced concrete slab covering approximately 60 square meters, installing a sloped transition ramp of approximately 15 square meters with integrated stormwater channels, and sealing the roadway shoulder berm to prevent erosion. All concrete must meet a minimum strength of 35 MPa, with a cement content of 320 kg/m³, a maximum aggregate size of 19 mm, and a slump between 50 and 100 mm. Reinforcement requirements include 6x6 W4 or heavier welded wire for the driveway and #6 or heavier rebar for the ramp. Surfaces must be finished with a coarse broom finish aligned parallel to the entry gate, achieving a flatness (FF) and levelness (FL) rating of 12, with control joints spaced every 3 meters. The project must be completed within 60 days of construction start, with a one-year workmanship guarantee required upon final acceptance. Solicitations are available via SAM.gov, the U.S. Embassy Bangui website, and in hard copy at the embassy gate during business hours, and contractors are required to attend a mandatory site visit on June 23, 2026. Proposals must be submitted electronically to Banguiprocurement@state.gov no later than June 26, 2026, before 1:30 PM local time, with late submissions rejected.

All work must comply with U.S. Embassy safety standards, including EM 385-1-1, and daily safety briefings are mandatory. Local insurance payments for all employees must be documented monthly throughout the project. No construction may begin until the Contracting Officer issues a Notice to Proceed and all administrative documents are approved by the Contracting Officer’s Representative.
