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%.

Window Selection & Pre-Roof Construction Meeting



Today we had a meeting with Peter Swislosky & Dave King from Bruss Construction, Tom McElreavy from Selectwood (local building supplier), Ryan Burke from AW Hastings (Northeast Marvin distributor), James Petersen and myself (Petersen Engineering). The first half of the meeting we dialed in our window selections, the second half we went over some short term construction logistics.

Window decisions:
-Use standard size windows to minimize costs. Reason: Buss is already going to be repairing and building out the window rough openings. Altering the opening dimensions + or - a 1/2" here or there is easy to do for them and will save us from having to go with custom sizes. Custom sized windows run 25% (ballpark) more than standard "off-the-shelf" sized windows.
-Field install all exterior trim. Reason: It is a factory option to have it pre-attached to the window casement. Standard factory thickness is 7/8" we need 3/4" in order for our furthest most edge of our siding to be flush with the trim. 5/8” is too thick. Having 3/4" costs more to have done from the factory. We decided it would be more economical to have Bruss Construction install the 3/4" on the field.


The second half of the meeting we dialed in some short term logistics for roof construction.

Highlights:
-staging may begin being erected as early as Friday of this week
-Bruss will have carpenters on the roof shortly after staging is erected
-temporary repairs need to be made to sill before doing roof work (about a hour or work)
-30 yard dumpster to be placed in driveway close to building
-strategies for controlling interior dust (Sheet of plastic in attic, negatively pressure rooms when interior work is done. We are about to shake this building and make dust fly out of cracks we didn’t even know existed!)
-discussed material storage strategies
-planed to have carpenter come out to remove some window trim to learn about the existing window rough openings better before ordering any windows
-received a general warning that the job site is going to "look like a job site at times" and not to worry about it because it is going to be cleaned up at the end of day everyday
-decided to go with Spruce siding because it is less expensive, indigenous to this area and historically accurate to what would have been used 100+ years ago
