project Details
Expedited service to solve emergent problems
Due to the emergency nature of the force main failures, Sebago Technics implemented an expedited design and bidding process to fast-track the replacement project. The firm provided civil engineering services including surveying, permitting, construction documents and bidding assistance, and construction administration. The project required careful coordination of temporary bypass piping to maintain sewer service during construction while the new force main was installed.
Working directly with the City of South Portland as the client, Sebago Technics helped structure contractor incentives for early construction completion to minimize the risk of additional environmental impacts. This project demonstrates Sebago Technics’ ability to respond quickly to infrastructure emergencies while maintaining high engineering standards and environmental protection measures for critical municipal utility systems.
