Cost Estimating and Management

Bob recognizes the importance of having accurate cost estimates before a shovel even goes in the ground. Accurate estimates are needed for budgeting, to verify or modify design decisions at the various stages of the project development and to analyze the accuracy and fairness of contractor bids. Estimating for contractor hard bidding is also something that Bob specializes in. Estimates will utilize the latest wage data with our own material and labor productivity costs database. We follow CSI formatting when required by general contractors or engineers’ clients. Estimates that require different Levels of detail follow AACE requirements.

Looking Over Architectural Plans

CPM Scheduling

Bob provides his clients with Critical Path Method (CPM) scheduling services, an essential requirement for effective construction project management. This includes the preparation, analysis, and updating of baseline schedules based on actual project progress.

Deliverables are prepared using the latest versions of the industry’s scheduling software, including Primavera, Sure Track, and MS Project.
