The computer may be used to assist in cost estimates, financial models, and scheduling for the construction.
Scheduling. Most builders agree that ‘as the building schedule goes, so goes the whole operation.’ When scheduling is bad, everything else suffers, especially quality, efficiency, employee relations, and customer satisfaction. The two techniques that are widely used in the field to aid in better scheduling are the PERT and Gantt charts. A Project Evaluation and Review Technique (PERT) chart provides step-by-step guidance in the construction of a project. The PERT chart provides both a plan to complete the project and checkpoints to monitor programs on the project. The Gantt chart is a graphic representation that compares estimated timetables for progress with actual progress performance. It helps the contractor keep the project on schedule.
Cost Estimates and Financial Models. Estimating is one of the most important aspects of a building contractor’s business. An accurate and up-to-date database of unit prices is a must. Most estimators use standard databases which are regularly updated for each section of the country. Financial models are needed for larger, complex projects where millions of dollars are involved. Keeping track of financing, cash flow, and payment schedules can directly affect the project schedule as well as the profit margin. A financial model provides a road map for the project that ensures a smooth, uninterrupted construction schedule.
