A Brief History

The project entails repairing the building at 335 Maplewood Ave in a manner that meets both preservation and sustainability goals. The building is the new location for Petersen Engineering, a firm that has been located in Portsmouth since 1992, and specializes in sustainable building engineering. We intend for this project to showcase techniques & materials that promote both preservation and sustainability and intend to share all aspects of the project locally and regionally through open houses, presentations, industry tradeshows, case studies and publications. We foresee this project being a valuable educational tool to demonstrate that preservation goals need not be compromised by sustainability goals. We have teamed with Bruss Construction who we know from past collaborations has exceptional experience and expertise on projects with the dual goal of preservation and sustainability.

The project received approval by the Historic District Commission on January 6, 2010 with construction scheduled to begin early February 2010.

The projected peak heat loss reduction is 85%.

Floor sanding

It has been a relatively quiet week with exception for the Blue Angels circling the office and the constant screaming of a 220 volt floor sander the last 2 days.

Heritage Hardwood Flooring from Lebanon, ME has been on site the last couple of days sanding down the floors in the office being refinished.

Once they are done sanding, they are going to hit the floor with 3 coats of varnish. We can't wait to see what it looks like!

This is the sander they are using for most of the floor. It is a the tank of belt sanders. They also brought a couple of smaller sanders for edges and hard to reach places.


Back and forth...

This is one of the smaller sanders used for the edges.

The sanders are also hooked upto a dust collection system in the truck. By law the room needs to be taped off with plastic bags and everybody in the room must wear a mask because the risk of sanding lead paint. The dust collection system did a pretty good job at keeping the room comfortable to be in.
