KITTERY, Maine (NNS) -- Naval Facilities Engineering Command (NAVFAC) Mid-Atlantic's Northeast Integrated Product Team (IPT) awarded the second of two modernization contracts for work on buildings 174 and 178 at Portsmouth Naval Shipyard to Environmental Chemical Corp., of Marlborough, Mass., March 19.

The projects, funded through the Navy's Restoration and Modernization, Energy budget have been designed to save the shipyard millions of dollars in energy costs over the continued lifetimes of the buildings. The two projects are related in nature, but will see different types of work performed on the buildings.

The building 178 project consists of structural repairs and modernization of the former naval shipways, while the building 174 project will consist of a whole building renovation to 157,000 square feet of the West End Waterfront Support Facility.

Public Works Department (PWD) Maine was responsible for the design effort for each of these projects, each worth more than $35 million. Cmdr. Brian Weinstein, Maine public works officer, said that local interaction was helpful in a successful design of this project.

"We were able to quickly overcome any design challenges, thanks in part to the daily interaction with the shipyard staff," said Weinstein. "Our staff of professional engineers has intimate knowledge of the shipyard facilities and mission, which is vital to a successful renovation project in mission critical facilities."

Weinstein added that PWD Maine engineers worked with the Maine State Historical Preservation Office to keep the existing building facades' historic look, while adding energy-efficient materials that will improve the buildings' energy usage performance. The shipyard, established in 1800, is part of the local historical district.

The work on building 174, which supports waterfront shops and 1,700 personnel for their work on the Virginia and Los Angeles-class submarines, will include major energy efficiency repairs to both the exterior and interior building systems. This will include replacement of older inefficient heating, ventilation, and air conditioning systems, electrical and plumbing systems, the installation of a solar hot water system and a 16 kilowatt photovoltaic panel system for power generation.

The building's energy usage will be managed by an internal metering system that will help control the use of electricity and water.

The building 178 project will see similar upgrades, to include smart-skin technology on the exterior of the building that uses its large surface area for solar power generation and solar thermal heating. The renovation will also replace a critical shipyard steam line, increasing the long-term reliability of all ship servicing.
