Contractors warn electrical and network delays could push temporary occupancy beyond July
Summary
Project managers told the Town of Cheshire building committee that electrical supply problems and district-supplied network switches are the main risks to the North End substantial-completion timeline; the committee heard that transformer energizing is scheduled and staff are pursuing a recovery plan but a TCO could slip into early August without earlier switch delivery.
Project managers told the Town of Cheshire school building committee that electrical and low-voltage network delays are the chief threats to meeting the North End school's substantial-completion milestones.
"Eversource is setting the transformer on Monday and is energizing the building on Tuesday," Ryan said, noting weather could shift that work by a day. Still, contractors said a months-long set of phase-one supplier issues and mis-delivered electrical components had kept lights and ceiling work from progressing earlier in the schedule.
Dave, the on-site schedule lead, walked the committee through revised milestone dates for buildings D, C, B and A and flagged the gymnasium as a critical path item. "We don't want to take the risk of ruining that floor by installing it too early," he said, describing the need to control humidity with HVAC startup before wood flooring installation.
An additional constraint is district-provided network switches. "My integration contractor needs about 2 weeks or so of integration and programming after those network switches are installed before you can have a fully running fire alarm system, elevator," Ryan said. That dependency means, he explained, that if switches arrive on the currently scheduled mid-July date, the earliest realistic window to seek a temporary certificate of occupancy (TCO) is the first week of August.
Committee members asked what the town will do to accelerate elements under local control. The construction manager described plans to add an extra flooring crew, run six-day schedules and move final cleaning earlier in some areas so teachers can begin staged move-ins even while signage and decorative murals await completion.
Why it matters: A TCO is the life-safety milestone that enables teachers and some staff or furnishings into a building ahead of full occupancy. Delays tied to third-party network equipment and a subcontractor supply chain can push that milestone into a later window, complicating move-in and the start of warranty and commissioning schedules.
Next steps: Project staff said they will continue daily scheduling updates, advise the committee if the network-switch dates improve, and pursue any workable workarounds that do not compromise life-safety system integration.
