The Wilmington project is a clear signal that for McCarty the construction downturn sparked by COVID-19 was short-lived.
“COVID slowed us down during the second quarter of 2020, but work has rebounded since then,” said Patrick McCarty, P.E., President of the Leominster, Massachusetts, company. The family-owned McCarty Companies consist of two separate operations – McCarty Engineering Inc. and McCarty Associates Inc. – that together can provide project management, general contracting, civil engineering, and site development and construction.
“Virtually 100 percent of our business comes from referrals,” he explained. “Our projects vary in size and type from small residential septic design and landscaping to medium and large commercial and industrial site work and building construction.”
Wilmington is a typical medium sized project for McCarty involving both civil and building construction. There were a number of existing buildings with occupants and commercial operations at the site when Gerrity Stone purchased it. Gerrity then leased all but two existing buildings back to the seller. Those two structures were demolished by subcontractor ADEP Group of Lawrence, Massachusetts, to make room for a new pre-engineered metal building manufactured by Star Building Systems. McCarty, an authorized Star Builder, will erect the structure.
McCarty began site work in February 2021, according to Matty Arya, the contractor’s Project Manager. Arya is relying on a fleet of Caterpillar machines to excavate and grade the site. Among these are a D5 dozer, a 725 articulated off-highway rock truck, a 938K front-end loader, 330 and 330D excavators, a 303 mini-excavator and a 319 excavator with a hydraulic bucket thumb attachment that facilitates handling boulders. Utilizing this equipment, McCarty has performed general excavation with cuts up to 12 feet, placed about 1,200 cubic yards of imported stone, and carried out general grading. The contractor is also responsible for foundation excavation, underground utility installation including SDR 35 PVC sewer pipe, electrical conduit, and ductile iron and copper water pipe. An estimated 50,000 square yards of paving with two courses of bituminous concrete will be performed by subcontractor A F Amorello & Sons of Worcester.
Arya said the earthwork did not present any unusual challenges. “The site is relatively dry, even though the water table was pretty high. We were able to control the water with a sump and some pumps. We also ran into a lot of boulders at the site, which we took care of with a rented crusher. That machine crushed boulders down to between a half-inch to an inch. We will be reusing all of the crushed stone on the site in areas requiring backfill, including the Star building when we erect it.”
Substantial, meticulous excavation and concrete form work is required for the new building’s reinforced concrete walls, footings, and piers. The single-story pre-engineered metal building has an overall length of about 372 feet and a width of about 123 feet, with 60 concrete piers, a 6-inch slab on grade, and an 8-inch-thick concrete perimeter wall. The wall varies from about 9 feet to 11 feet tall and rests on a 1-foot-thick by 4-foot-wide footing.
Started in 1982 as McCarty Associates, a construction management and consulting firm, the McCarty establishment developed into The McCarty Companies, which offers services ranging from design, site acquisition, permitting, and construction to a completed building, ready for occupation. The civil engineering design and permitting part of the business was established in 2004.
President Patrick McCarty has a Bachelor of Science degree in civil engineering from the University of New Hampshire and is a Registered Professional Engineer.
