From Concept to Creation

Your project isn’t final until the construction is completed.  It sounds straight forward but rarely do all construction projects get completed on time and within budget. H2M’s division of Construction Services can help you reach your goals for bringing your project to a successful conclusion. Whether it’s paving a parking lot or the ground up construction of a new building, our team of construction inspectors are available to assist with the monitoring for compliance with your plans and specifications to ensure quality control is maintained throughout the project construction. We can assist with material sampling and testing, quantity measurements, manufacturer specifications and compliance with regulatory permits. Our inspectors are certified from various nationally recognized organizations including OSHA, NICET, ACEC, and ACI.
