Philosophy of DeCarlo & Doll, Inc.

DeCarlo & Doll prides itself in its ability to produce quality projects, within budget, and on schedule. Our approach to this paradigm is based on Cost and Quality Control parameters implemented throughout our firm.

Cost control at DeCarlo & Doll is a continuous operation. Our Construction Management department continuously offers estimating support to our design staff. Project construction costs are typically estimated at the conceptual phase of each project, and subsequently at the schematic, design development, and construction document phases. Our Construction Management staff, because of their day-to-day involvement with construction trades and materials, is intimately familiar with the Connecticut construction micro-environment and its implications for project costs. As a result, DeCarlo & Doll has been very successful in its delivery of complex multi-disciplined construction projects within the allocated budgets.

In parallel with our cost control measures, DeCarlo & Doll has been successful at implementing aggressive peer-review quality control measures. As a multi-discipline firm, we thrive on cross-exchange of design information. As a multi-layered professional firm, each discipline has the ability to have a second professional periodically review the work of the design team. This quality control feature is typically exercised at the conceptual phase of each project, and subsequently at the schematic, design development, and construction document phases.

DeCarlo & Doll's project management philosophy is to assign a Team Leader to each project. The Team Leader is responsible for client contact and resource allocations. Team Leaders shepherd the project through client and regulatory reviews, cost and quality control measures, bidding, construction administration, and delivery of the constructed project.

As a full service firm, DeCarlo & Doll's only mission is to assist our clients and together, through personal commitment, provide the better solution.
