Kiely Family of Companies

What Kiely Family of Companies does

Kiely Family of Companies is a privately held, family-owned design-build construction and engineering enterprise founded in 1952 by John F. Kiely Sr. and headquartered in Tinton Falls, New Jersey. Organized into three reporting lines — Civil, Development, and Equipment — it delivers integrated infrastructure services through wholly owned operating companies including J.F. Kiely Construction Co., J.F. Kiely Construction Co. of PA, Kiely Engineering, Kiely Pipeline Integrity, Kiely Industrial Technologies, Kiely Development Co., K+T Materials, and Wheelwash, supplemented by acquired brands such as Barton Construction Corp. (water resources), Industrial Treatment Technologies (wastewater), All Bright Electric and Sodon Electric (electrical and renewable energy), and M. O'Herron Company (natural gas and water infrastructure).

The company's core capability is single-point-of-accountability design-build delivery for natural gas, petroleum, water resources, electrical, and renewable energy infrastructure, executed across engineering, construction, inspection, maintenance, HDD (trenchless) drilling, and project management service lines. Underlying technical components include horizontal directional drilling for minimally disruptive underground utility installation, pipeline integrity inspection and management for midstream operators, hot-mix asphalt production and recycling, and design-build integration spanning civil, structural, utility infrastructure, mechanical, and energy disciplines. It maintains a fleet of more than 1,200 active vehicles and equipment pieces and operates from 11 U.S. locations plus an India office, with strategic concentration across New Jersey, Pennsylvania, and Delaware and growing presence in Florida and West Virginia.

The business model is B2B and project-based: revenue is generated through negotiated, quote-driven contracts awarded via competitive bidding, RFP responses, and long-term partnership relationships with publicly traded utility companies (including South Jersey Gas and New Jersey Natural Gas), municipal governments, energy companies, and private enterprises. Revenue streams include engineering and construction services (professional services), equipment sales and leasing, hot-mix asphalt manufacturing, and real estate development. As of 2025 the company employs more than 1,800 team members, is consistently ranked on Engineering News-Record Top 400 General Contractors and Top 600 Specialty Contractors lists, and has executed five acquisitions since 2018 with no external institutional shareholders disclosed.
