Retail center, Mount Laurel NJ

The job

Three rooftop units at 7.5 tons each — 22.5 tons of cooling in total — came off and three new ones went on. Straightforward work, of the kind that makes up most of a commercial replacement schedule.

The part that needed planning was the crane. Any rooftop changeout at a retail center means staging a crane in a parking lot that customers and tenants are using, picking the old units off and the new ones up over the building, and doing it without closing the center.

What we did

• Removed three existing rooftop units
• Set three new 7.5-ton units — 22.5 tons total
• Crane coordination and lot staging around an operating retail center
• Electrical, controls and startup on each unit

Why routine is the point

Not every job is thirteen units in a day. Most commercial replacement work looks like this one: a handful of units, a crane, a morning of lifts and an afternoon of connections. It is worth showing, because the ordinary version is what most buildings actually need and the thing a facility manager is usually trying to price.
