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%.

Basement Slab Test Holes

We are trying to establish how far down our foundation walls go. This will impact how far down we can excavate near the walls. We intend on insulating under the slab, installing a interior perimeter drain and would like to maximize head height as much as possible throughout without undermining the foundation walls. Todays digs did not go quite as planned. We need to come back with some heavy artillery (sledge hammer) to break through the slab. The big pry bar just could not chip its way through effectively.

We just purchased a "flip" video camera to help document the little day to day events that make up this big renovation. This is the first of many videos.
