Abbot Hall Exterior Renovations and HVAC Improvements (Marblehead, MA) - The project scope included the complete historic preservation of the masonry exterior envelope of Abbot Hall (1876), the town hall of Marblehead, MA, and upgrades to building HVAC systems, including 13 new geothermal wells. Role: during construction documentation, I produced the bid specifications and developed preservation details. During construction administration, I acted as Project Manager and performed all duties from public bidding (M.G.L. c 149) through project close-out.

Fort Sewall Phase II - Fort Restoration (Marblehead, MA) - The project scope featured the final preservation and repairs at the Revolutionary-era Fort Sewall (in Fort Sewall Park), including selective masonry restoration, replication of historic wood doors and frames, and addition of stone dust floors within the Redoubt rooms. (This project received a matching grant from the Massachusetts Preservation Project Fund, and the project team collaborated with the Massachusetts Historical Commission throughout the process.) Role: I acted as project manager from existing conditions documentation through design, public bidding (M.G.L. c. 149), construction administration, and close-out.

Fort Sewall Phase IIB - Site and Accessibility Improvements (Marblehead, MA) - Fort Sewall is located in a park on the shores of Marblehead Harbor. This project, to be completed Spring 2021, includes regrading the 2.2 acres for accessibility and general site improvements, and replication of historic cannon platform through interpretive hardscaping. The preservation architect, landscape architect, and the Fort Sewall Oversight Committee collaborated on the site design to develop a solution that recalled historic layouts of the grounds. Pictured above is the 1820 Poussin Plan depicting the fort's plan circa the War of 1812. This era is significant for the fort because it protected the U.S.S. Constitution from two pursuing British warships in 1814.

Fort Sewall Phase IIB - Site and Accessibility Improvements (Marblehead, MA) - plan for site improvements. The historic cannon platform will be reinterpreted in stone dust to show its location circa 1814 (on the upper parade grounds, right side of the plan above). Granite cannon silhouettes, showing typical cannons used at the fort, will be embedded in the stone dust paving. Other project features include fully accessible walkways throughout the site, resetting of historic granite site stairs, new granite site stairs with custom metal handrails, and new trees and other plantings. Role: I acted as project manager from existing conditions documentation through design, public bidding (M.G.L. c. 30), and construction administration.

Insulet Clean Assembly & Corporate Office Facility - The project scope included renovation of an existing 200,000 square foot office building, and new construction of a 100,000 square foot addition for Insulet Corporation’s global headquarters and medical device manufacturing operations. The 300,000 square foot facility was constructed in three phases concluding in Fall 2018. Role: I acted as Project Manager for Owner Support Services prior to Construction Administration. Located in-house at Insulet’s Billerica, MA site, I worked directly with the Owner and reviewed pre-purchase documents, prepared the Owner for the construction process, participated in Value Engineering, and conducted additional pre-construction studies. I acted as the co-Project Manager for Construction Administration during the second phase of construction.
