quality assurance / quality control

Our QA/QC program safeguards that proper procedures are used on every project. We observe and document that construction is being performed in accordance with the project plans, specifications. We collect and evaluate data to verify that materials and techniques being used meet the standards required for the project, that proper methods are used for testing and analysis, and that we present our reports clearly, accurately and consistently. Special methods developed or modified to meet unique field conditions are properly documented in specific field procedures for reference and retrieval. 


Our record reflects a combination of a safety-oriented culture and practice such as tailgate meetings, site hazard analyses, and appropriate training.  We continually assess that projects are constructed in a safe and efficient manner, adhering to agencies, federal policies, procedures and requirements.
