D.C. FEDERAL COURT REJECTS DIFFERING
SITE CONDITIONS CLAIM BECAUSE CONTRACT
EXTENSIVELY DETAILED EXPECTED AND POTENTIAL SITE PROBLEMS

Often contractors seek to recover costs resulting from site conditions which differ from what was anticipated in the contract documents. However, as indicated in Guy F. Atkinson Construction Co. v. Washington Metro. Area Transportation Auth., 2006 U.S. Dist. Lexis 53468 (D.D.C. 2006), if the contract documents extensively detail expected and potential site problems, the contractor may have a difficult time recovering for the differing conditions which it encounters.

In Atkinson, the contract for a tunneling project consisted of general provisions and standard specifications, as well as special provisions. The special provisions included a geo-technical design report (Appendix G) which detailed anticipated subsurface conditions and commented extensively on methods of tunneling, soil types, and water control for the project. Of particular interest, Appendix G addressed subsurface conditions in the area later in dispute in detail, advising bidders that the particular area would require dewatering of the sand and possibly chemical stabilization. To combat potential water problems on the project, the contract required installation of a dewatering system to facilitate tunnel excavation, as well as devices to monitor water control, and required procedures for the control of groundwater to be performed under the supervision of a specialist. Responsibility for the design, installation, and monitoring of the dewatering system rested solely with the contractor. Moreover, the contract mandated that the contractor collect and submit water monitoring data, detailed dewatering plans, and the qualifications of its specialist to the owner for approval, and emphasized that dewatering criteria would be rigidly enforced.

Despite high water readings and the potential for water inflows as described in Appendix G, the contractor’s tunneling work did not encounter any difficulties at first. Hence, the contractor continued tunneling until it first observed water flowing into the tunnel. Due to continued water inflows thereafter, the contractor’s tunneling progress eventually slowed almost to a stop. The contractor then informed the owner that the water entering the tunnel constituted a differing site condition—the amount of water inflows far exceeded the amounts originally indicated in the contract. The owner denied this claim. The contractor made two other claims, but the owner rejected both. After the owner rejected the third claim (reaffirming its position that the water was indicated in the contract documents), the contractor completed the tunneling without encountering any further difficulties.

Pursuant to the contract, the contractor submitted a claim to the owner for additional compensation as a result of the differing site conditions and additional wells. When the owner denied the claim, the contractor appealed to the board of contract appeals. The board unanimously denied the contractor’s claim, and the contractor filed suit to overturn the board’s decision.

The court determined that in order to recover on its differing site conditions claim, the contractor had to show the following: the contract documents represented conditions which formed the basis of the contractor’s claim; the contractor acted as a reasonably prudent contractor in interpreting the documents; the contractor reasonably relied on the contract’s representations; the conditions actually encountered differed materially from those represented in the contract; and the contractor’s claimed excess costs were attributable to the materially different conditions. However, the court concluded that the contractor could not show that the tunnel conditions actually encountered differed materially from those represented in the contract. The contract documents were found to be replete with indications warning the contractor of the precise conditions actually encountered. The court found that Appendix G described in great detail, the locations, the expected tunneling problems, and specifically addressed in extensive detail the subsurface conditions of the areas in dispute. In addition, the court determined that there was no evidence supporting the contractor’s contention that the water encountered did not come from the water table expressly indicated in Appendix G. Accordingly, the court held that substantial evidence supported the board’s conclusion that the water inflows came from a source indicated in the contract, and therefore, were not conditions differing materially from the contract.

As Atkinson demonstrates, the success of a differing site conditions claim typically depends on how well the contract documents describe the potential for such conditions. Contractors that are provided with extensive details of expected site problems in their contracts should be aware that they will be hard-pressed to prove that they were surprised by any difficult conditions encountered in their work.
