Afghanistan's Ghulam Khan Road Project: Construction of the Road and Bridge Generally Met Contract Requirements, but Deficiencies Have Created Safety Hazards for Users
This report discusses the results of SIGARs inspection of the Ghulam Khan Road project. In September 2015,the U.S. Army Corps of Engineers (USACE) awarded a $4.5 million firm-fixed-price contract to Batoor Design and Construction Incorporated (BDCI), an Afghan company, to design and construct a 4.3-mile paved asphalt road from the Gurbuz district to Khost City in Khost Province. The contract also required BDCI to construct 21culverts under the roadway, a 13.1-foot-wide, one-lane bridge, and a 4.9-foot-wide sidewalk on both sides of the bridge. The project was completed in July 2017, and the construction warranty expired in July 2018.During our July and November 2018 site visits, we found that BDCI generally built the Ghulam Khan road and bridge according to contract requirements and technical specifications. For example, BDCI constructed an asphalt road to the required 4.3 miles in length and about 4 inches in depth. However, we identified five construction deficiencies, four of which involved the bridge spanning the Kaitu River. Specifically, the bridges concrete support beams had honeycombing, and BDCI did not build the bridges stone foundation barriers, retaining walls, and protective railings to required heights. Three of these deficiencies could impact the bridges structural integrity. For example, if the support beams are not repaired, moisture will enter the concrete and cause the reinforcing steel rods to rust and the concrete to disintegrate. This damage could cause the concrete beam to fail.
