Overview

Walton Construction was an American privately owned construction company founded by Greg Walton in Kansas City, Missouri, in 1985. It developed from a regional contractor into a large general-construction business with work spanning commercial, mixed-use, public, federal, military, and other complex building projects. Its early landmark assignment in Kansas City was the Bartle Hall Convention Center, completed in 1994 at a reported total construction cost of $91.7 million. That project helped establish the company’s local profile and provided a platform for broader expansion. Over the following two decades, Walton Construction built a substantial project portfolio in the central and southern United States. Notable developments associated with the company included the Legends at Village West in Wyandotte County, Kansas, and the Zona Rosa mixed-use development. The company also operated divisional offices in Dallas, New Orleans, Shreveport, Springfield, and St. Louis, reflecting a network designed to support projects across multiple U.S. regions. During its expansion, Engineering News-Record reportedly ranked Walton among the 100 largest general contractors in the United States, and the company’s annual revenue exceeded $800 million at its peak. These figures describe a historical period of scale rather than a current operating profile. After Walton passed its 25th anniversary, its leadership and corporate structure changed. William G. Petty, commonly referred to as Bill Petty, became chief executive officer and moved the headquarters from Kansas City to New Orleans in mid-2010. The New Orleans division placed particular emphasis on large federal and military construction projects throughout the United States. The business subsequently changed its name from Walton Construction Company to WCC Companies after Petty sold certain assets to CORE Construction, an Arizona-based contractor. The reorganization marked the end of Walton Construction as the principal operating name described in the company’s earlier history. In August 2012, Petty formed The WGP Companies, consisting of WGP Associates, LLC, a management-consulting firm, and WGP Construction, LLC, a general contractor. The WGP businesses focused on federal construction contracting, complex surety-default projects, and disaster-recovery work. Their stated geographic scope included the continental United States and overseas locations outside the continental United States, including Christchurch, New Zealand; Manila, Philippines; and Guantanamo Bay, Cuba. Walton Construction is therefore best understood as a historical construction-company brand whose operations and assets evolved into successor businesses rather than as a currently independent major contractor.

History

Walton Construction was established in 1985 by Greg Walton in Kansas City, Missouri. It began as a privately owned construction company and secured a significant early Kansas City assignment with the Bartle Hall Convention Center. The convention center was completed in 1994, with a reported total construction cost of $91.7 million. The project became an important reference point in the company’s development from a local contractor into a larger regional and national general-construction business. During the next two decades, Walton expanded its project activity and office network. Its work included the Legends at Village West development in Wyandotte County, Kansas, and the Zona Rosa mixed-use development. The company maintained divisional offices in Dallas, New Orleans, Shreveport, Springfield, and St. Louis, allowing it to pursue work in several U.S. markets. Its portfolio and scale led Engineering News-Record to place Walton among the 100 largest general contractors in the United States. The cited account also states that annual revenue exceeded $800 million during the company’s peak period, although no financial reporting source or specific year is provided here. A corporate transition followed Walton Construction’s 25th anniversary. William G. Petty became chief executive officer and relocated the headquarters from Kansas City to New Orleans in mid-2010. Petty retained a New Orleans divisional operation specializing in large federal and military construction projects across the United States. The company later changed its corporate name to WCC Companies after Petty sold certain assets to CORE Construction, based in Phoenix, Arizona. This transaction and rebranding ended the company’s operation under the Walton Construction name as described in the available reference material. In August 2012, Petty established The WGP Companies. The group included WGP Associates, LLC, a management-consulting business, and WGP Construction, LLC, a general contractor. The new businesses concentrated on federal construction contracting, complex surety-default projects, and disaster-recovery projects. Their stated activity covered both the continental United States and overseas locations, including Christchurch in New Zealand, Manila in the Philippines, and Guantanamo Bay in Cuba. The available material does not establish a separate continuing corporate identity for Walton Construction after the WCC Companies reorganization, so the historical brand is treated as defunct.
