King George staff flag urgent Dahlgren wastewater repairs; Bowman proposal to return for vote
Summary
County staff introduced a late Bowman Engineering proposal of roughly $312,345 for immediate structural repairs and prioritization work at the Dahlgren Wastewater Treatment Plant tied to a $4 million bond; no vote was taken — staff will refine the proposal and return to the board, aiming for the Dec. 3 meeting.
County general manager (Mr. Hamilton) told the board the Dahlgren Wastewater Treatment Plant has an identified leak into a wet well that is threatening a concrete structure and requires near-term structural and short-term repairs. He said the county sold a $4 million bond for upgrades and needs to begin spending on high-priority work.
Hamilton told the board he asked Bowman Engineering to prepare a final-design proposal for immediate priority repairs and described the submission as a not-to-exceed proposal of about $312,345 with a roughly 32-week term. "This is basically the initial... final design proposal for what they're calling the immediate needs priority," he said, and noted he had received the proposal late in the week and was not prepared to recommend approval that night.
Hamilton described the leak as appearing in a recycled-wastewater line and leaking through concrete into a wet well “in a state of imminent failure,” and explained Bowman will deploy cameras and structural engineers to recommend a short-term fix. He said some short-term actions have already been taken within his delegated authority and that Bowman will provide structural engineering services and recommendations to allow safe maintenance and to enable longer-term upgrades.
Hamilton and other board members discussed the need to budget for engineering services during construction, saying the county lacks in-house staff to review requests for information and inspection tasks. Hamilton said he will refine the proposal together with Byrne/Bowman representatives and return the item to the board for a vote, targeting the Dec. 3 meeting.
What happens next: staff will work with Bowman to refine scope, compare it to the July report on plant needs and return the proposal to the board for formal consideration and a vote. The board also discussed preparing a legislative agenda to seek additional state funding support.
Context and costs: the Bowman proposal is described as not-to-exceed $312,345 and tied to earlier recommendations for Dahlgren plant upgrades funded by a $4 million bond sale; staff stressed urgency but did not seek immediate authorization that night.
