Engineers urge soil testing and water‑flow tests; committee floats net‑zero goals

Project engineers told the committee that Phase I environmental review for the entire site is complete and found no major red flags, although it identified an area with a former oil tank that may require deeper testing if deep excavation is proposed. A Gilbane representative and other engineers recommended soil characterization (test pits/borings) this summer to determine whether excavated soils would need export and to reduce the risk of unanticipated remediation costs during construction.

The engineers recommended a water flow test to establish street pressure and the likelihood of needing a fire pump if the building is sited atop the upper hill. The group discussed the cost implications of adding a fire pump and the operational sequence while the existing building remains occupied. Committee members repeatedly asked for confirmation of where the existing septic/leach field and reserve are located and were told the design team will share existing condition drawings and older borings to inform decisions.

Separately, committee members spoke in favor of exploring ambitious sustainability targets. One committee member suggested a net‑zero aspirational goal and asked the architecture and engineering team to identify options (geothermal, heat pumps, hybrid systems, solar and envelope improvements) and associated costs. The committee proposed forming a small sustainability subcommittee to review options and to feed recommendations into schematics and cost estimates.

Next steps: project team to coordinate flow testing and soil characterization this summer, share existing borings and site drawings, and scope sustainability measures for cost review in schematic design.
