With a list of 90 itemized faults in the construction of Chilmark’s first affordable housing development, frustrated town officials this week demanded that Seaver Construction president Scott Seaver take personal control of the project.

The list of flaws, which the site superintendent says have been corrected, occurred during the past nine months of work by the Woburn-based firm on the Middle Line housing development. They included improper insulation, a botched firewall, crooked shingles, shallow floor levels, cracked bathtubs and possible mold on sheetrock that was installed at the wrong stage of the building process.

“We’re really losing faith in the way things are going,” selectman Frank Fenner said at a special meeting on Wednesday where Seaver was granted an additional 30 days — until mid-August — to complete the project. The firm also agreed to weekly town inspections of work. “We want to do it right, and we want to do it once,” Mr. Fenner said.

Construction was scheduled for completion by mid-July with families to move in by September. Residents will be selected through a lottery in the next few months for the 12 affordable housing units – six houses and three duplexes, each containing two affordable rental units.

Voters approved the 21-acre project off Tabor House Road in 2005. Seaver was awarded the bid last summer for $1.9 million and broke ground in the fall. It was the only bidder for the project after the lower bidder was disqualified.

Seaver Construction already is under fire in Tisbury, where its work on the town’s new $7.4 million emergency services building has been plagued by delays and poor workmanship. A year after construction began, town selectmen this month complained that the structure still is not weather tight and expressed concerns that leaks have caused damage to building materials inside the structure. It is also behind schedule.

According to Chilmark’s owner project manager, Michael Josefek, and lead architect for the Middle Line project, David Handlin, the faults are due to speedy but insufficient craftsmanship, completing tasks out of sequence, and not submitting materials for approval by the architect in a timely matter, if at all.

Zoning board of appeals administrator Chuck Hodgkinson said work was being performed before it was thoroughly considered or approved. “I hope the extra month would give you time to say, ‘Here’s our schedule going to the end of August.’

“We’ve proceeded for urgency’s sake and that’s why we’re here today,” Mr. Hodgkinson added.

Clerk of the works Mr. Josefek said to Mr. Seaver: “I have to hear from you that you’re going take control of your project, that you are going to be overseeing the day-to-day operations.

“I need a commitment that Mr. Scott Seaver is going to take control of his company. Whatever assistance you need to help you achieve that goal, you need to sit down and make this happen.”

“My name is on it so ultimately it comes to me,” Mr. Seaver conceded after two hours of heated discussion. “The buck stops here. Obviously, yes, I’m going to take control.”

Mr. Josefek said it’s been a constant struggle communicating with Seaver. Even two weeks ago, he said, he had requested a recovery schedule that would incorporate the extra month extension, but Seaver had not provided him with one as of Wednesday’s meeting.

“I gave you explicit instructions I wanted to see a recovery schedule,” Mr. Josefek said. “Someone determined that’s not important to you. We have 20 people here and are unable to discuss a realistic schedule.”

Mr. Seaver said he was shorthanded both in the office and at the site, but that starting Monday there would be a second supervisor at the construction site.

“This has nothing to do with money,” Mr. Seaver said. “It’s frankly obvious we had personnel problems and that’s what started this whole thing in a negative fashion.”

Despite harsh criticism for the overall management of the project, Mr. Fenner, Mr. Josefek and Mr. Seaver praised superintendent Rick Senna for managing the site. As for the 90 item corrective log, Mr. Senna said all of the issues have been addressed and corrected.

“You guys are hopping in there three steps before it’s even finished,” superintendent Rick Senna said.

But Mr. Fenner said the town wanted work done right the first time around, citing shingling that could have been fixed at the beginning rather than taken down completely.

Zoning board of appeals member Frank LoRusso added, “The plumber had to rip out the insulation to put in the pipes and then the insulation was not put back properly.

“It doesn’t appear you guys are reading the spec when you start a new project. Something’s wrong – the workmanship is horrendous and that’s got to stop.”

For the architect, Mr. Handlin, safety has been his top concern. He pointed to finding sheetrock and insulation not installed properly for at least one building, adding it would not meet the necessary fire codes. Mr. Handlin said he was seriously considering having all of the sheetrock taken down so he could inspect the insulation.

“It’s untenable, it just can’t happen this way,” he said. “We have to get this project from this remedial mentality to one of mastery, where we’re all in control and not wasting time, but not dashing through things.”

In the end, both parties agreed to weekly inspections by Mr. Handlin every Wednesday before proceeding with the next phase of the project.

“You need to convince yourself that you can pull this off, and convince us you can pull it off,” Mr. Josefek said to Mr. Seaver. “It’s not hurting us to give [the extra month] to you. We want you to use it wisely, not shoving stuff through the door.”
