Douglas Crampton



Since joining WJE in 2000, Douglas Crampton has participated on numerous projects involving the investigation, analysis, and repair of existing structures. He has performed numerous computer analyses to model the behavior of existing structures, the failure mode of collapsed structures, and the performance of applied repairs/retrofits. Mr. Crampton routinely evaluates structural distress and provides remedial recommendations for residential and commercial structures.

Mr. Crampton has also participated in a wide range of projects involving the design, inspection, evaluation, rehabilitation, analysis, and construction observation of bridge structures, including peer reviews of bridges, tunnels, and other ancillary transportation structures. Following a partial ceiling collapse of a tunnel structure constructed during Central Artery/Tunnel project, WJE was retained to perform a “Stem to Stern” Safety Review of all transportation structures included as part of Boston’s “Big Dig” project. Mr. Crampton served as deputy project manager for this project, which involved a peer review of approximately two hundred steel and concrete bridge structures, twenty-two miles of tunnel structures, and 3,500 ancillary signage/luminare structures.
