After completing a feasibility study that assessed potential ways to update the Haverhill Public Library for its 21st century needs, OverUnder is designing the first phase of work to transform the 1960 facility. This includes remediation of the renovation that occurred in 1996, replacement of the building envelope with more energy-efficient elements, upgrades to existing geothermal wells, new mechanical systems, and interior renovations to improve patron services and community functions. The multi-pronged engagement with the community included participatory design, benchmarking tours, focus groups, and stakeholder interviews. The feasibility included concept design of three scenarios with associated cost estimates to assist the board of trustees to move forward with the funds raised.
