ROCKLAND, Maine — Construction of what would be Rockland’s tallest building appears to be ready to start in the spring.

The city’s code enforcement officer reported last week that he met with the new general contractor for the proposed 65-foot building that would be constructed at 250 Main St. The code officer reported that general contractor Fred Griego had returned from another project at Lyman Morse’s boatyard in Panama. Lyman Morse is the owner of the Rockland project.

“Work toward completion of the project will begin again this spring,” the code officer stated in the weekly report.

The first floor of the proposed building would be for retail stores and the second floor for offices. The third and fourth floors each would contain two residential condominiums, while the top floor would be reserved for a single residential condo.

The project received original approval from the Rockland Planning Board in October 2010. The foundation was constructed in October 2011, but then the project — estimated to cost $2.4 million — encountered delays.

The company has marketed the residential condos — referred to as The Lofts at 250 Main. The site is at the intersection with Pleasant Street where Hollydachs Pet Center and Aquarium had been located.

Lyman Morse is a boat-building company in Thomaston that planned the Rockland development to help keep its workers employed. The boatyard employs welders, plumbers and electricians. The company said it will use green technology in the mixed-use building.
