Built on trust since 1985, ALLCO delivers specialized construction expertise, self-performance, and relationship-first project delivery for public and private work.
Founded in 1985 by Thomas W. Harrison and Eugene R. Allen, ALLCO was built on trust, practical construction solutions, and employee development. Today, the company operates through four specialized divisions: Heavy/Civil Construction, Utility & Public Works, Disaster Recovery, and Commercial Construction. This structure allows each team to maintain focused expertise while drawing on the resources and capabilities of the broader organization.
ALLCO has completed more than $3.5 billion in construction projects for public and private clients. The company combines experienced leadership, skilled field teams, modern delivery systems, collaborative program management, and sustainability-focused building performance. Across every division, ALLCO remains committed to safety, quality, accountability, and dependable project execution.
ALLCO makes safety an integral part of daily operations. The company follows federal, state, and local regulations and applies practical jobsite judgment based on the conditions and circumstances of each project.
Every jobsite is required to maintain and reference the ALLCO safety manual. Superintendents serve as daily on-site safety managers, and every employee is empowered to identify, report, and help prevent potential injury.

ALLCO is a comprehensive construction company serving public and private clients across a wide range of project types. The company self-performs earthwork, site clearing, water and sewer installation, drainage systems, foundation work, wastewater treatment plant construction, and other specialized construction scopes. This in-house capability provides greater control over safety, quality, scheduling, and field coordination throughout each project.
Supporting that work requires an experienced and diverse workforce. ALLCO is an equal opportunity employer with professionals across estimating, engineering, project management, quality control, safety, field supervision, skilled trades, administration, and operations. These teams work together to solve project challenges, maintain accountability, and deliver dependable results from preconstruction through completion.
ALLCO has completed major construction work across Texas and Louisiana and gives back to the communities that helped make that success possible.
The company participates in community-supported educational programs, mentors small businesses through the State of Texas Mentor/Protege Program and Minority Business Councils, and supports the personal development of team members as they create a positive ripple effect in their communities.
