Addicks Servs., Inc. v. GGP-Bridgeland, LP, 2010 WL 4250054 (5th Cir. Feb. 8, 2010)
This case shows the effectiveness that explicit waivers and progress payments can have on precluding contractors from obtaining further pay for alleged extra work. A contractor sought damages for extra work and delay costs incurred in performing excavation and grading work for a developer. The Fifth Circuit, applying Texas law, granted summary judgment in favor of a developer because the interim waivers and accompanying progress payments unambiguously released any outstanding claims for payment of extra work performed before the date of each interim waiver.
