Each design project has a different set of requirements. Prior to any design development, interviews with the client determine what results are expected and what the design constraints are. We encourage our clients to work closely with us, particularly in the early stages of a project. This promotes efficient decision-making and a ‘team’ relationship. Through associate professional firms, D. Hittle & Associates is able to provide all of the resources necessary to match a client’s needs.


Within each discipline, Quality Assurance begins with internal reviews for document clarity, accuracy and technical correctness. Regularly scheduled team meetings coordinate elements provided by each discipline and compare the overall design to client expectations and objectives. Intermittent reviews with the client allow for modifications that will improve the final product. The result of achieving Total Quality Assurance has been to enhance our service strengths, continuously improve our value and bring clients back for repeat projects.
