Keeley Crane Service, a South Portland-based heavy equipment provider, hoisted a new HVAC system to the roof of Meetinghouse Arts and the First Parish Church, where the arts center is a tenant. The Arts and Cultural Alliance of Freeport is making changes at the sanctuary level of the church, which is at 40 Main St., to create space for performances, a gallery, classes and meetings. Plans call for preserving the historic character of the interior, while allowing the church to continue to hold services. Warren Construction of Freeport is the contractor. Elsewhere in Freeport, Shaw Bros. Construction is handling earthwork at the Residences at Crosstree, an apartment complex underway on Desert Road.
