OXFORD – Keiser Homes has announced it has signed a $4.5 million agreement with CTA Construction of Boston to build a 95-unit senior living center in Somerville, Mass.

The company will partner with New England Homes of Portsmouth, N.H., another modular manufacturer, to ensure it meets the schedule requested by CTA for the project, according to a statement issued by Keiser on Monday.

The project consists of 157 modules that total more than 85,000 square feet. The project, which will cost close to $20 million in total, is being funded by the Somerville Housing Authority and will be connected to a recently completed Visiting Nurses Association assisted-living center that was also funded by the housing authority.

“Keiser is excited about the Capen Court project,” said its president, David Cuttler. “It will showcase our strengths in engineering design and modular building to provide a beautiful and much needed building to the citizens of Somerville.”

Cuttler, who is a director of the Modular Home Builders Association of Maine, said he believes the project will expose people to modular construction.

“When people see the quality of today’s modular buildings and understand the process, including the controlled production environment and the ability to schedule a completion date, they realize that modular building is an attractive alternative to site-built construction,” Cuttler said.

CTA, the general contractor, will take delivery of the 157 individual modules being built by Keiser and supervise the setting and joining of the modules into one seamless building, Cuttler said. Delivery is expected in June.

Keiser, located on Route 121, will first build a production model of the unit design for Capen Court to be reviewed by CTA and the housing authority before beginning full production.

The project is expected to be completed by April 2010.
