Henry Lewis was just doing his job when, as senior project manager of Alexandria’s $81 million police headquarters project on Wheeler Avenue, he refused to authorize payments on invoices submitted by contractor Whiting-Turner that were insufficiently documented, including one for a million dollars that was post-dated a week in the future. Other invoices were for materials stored off-site — with no proof they had been purchased. The Howard-educated architect also refused to sign off on moldy, warped, wooden trusses that the contractor tried to install in a related project on Quaker Lane.
