Rockland — The Lyman-Morse mixed-use building site, located on 250 Main St., is tentatively scheduled to resume construction this fall contingent on the sale of units, according to a company spokesperson.

The proposed five-story building was planned by Lyman-Morse Boatbuilding of Thomaston to provide work for employees during the economic downturn.

According to the original plans for the building, the first floor would serve as retail space for either a store or restaurant. The second floor would provide office space for business use and the remaining top floors of the building would be available to purchase as condominiums.

Lyman-Morse employee Ron Defoe, who is overseeing the project, said there has been high interest in the residential units.

He said construction will not begin this summer to avoid congesting seasonal traffic. He added that construction stagnated earlier this year due to illness of the general contractor of the project.

In a statement from January, Defoe said the exterior of the building was expected to be completed by July 2012.

If construction begins this fall, the building will be finished by spring 2013, said Defoe.

The project plans include green technology and an energy-efficient design.

Between 10 and 15 Lyman-Morse employees are expected to complete the interior work on the building including any woodwork and cabinetry. The exterior work is being completed by outside subcontractors.

The Rockland Planning Board voted unanimously in December 2010 to approve the five-story, 65-foot long building. The former Hollydachs Pet Center, located at the same address, was torn down prior to the beginning of construction.

The project is expected to cost $2.4 million.
