This webinar
will discuss cost-estimating for the 10 major building systems and the 4 design
phases of a project. Pre-construction
estimating uses historical data, knowledge of foundation and structure systems,
experience, “rules-of-thumb” and the ability to fill the missing pieces as
tools for preparing estimates to maintain continuity during the various phases.
- 1.The cost of a building can be broken down into 10 major building systems i.e. Foundations, Structural Frame, Building Envelope, Interior Finishes, Vertical transportation, Fire Protection, Plumbing, HVAC, Electrical and Site Work. The Foundations and Structural Frame can amount to 30% - 40% of the Building Cost.
- 2.The establishing of a reasonably accurate estimate for the Foundations and Structural Frame early in the project is important for the following reasons: 1) as stated above the Foundations &Frame account for +/- 1/3 of the building cost, 2) creating a benchmark for comparison of future estimates, 3) The probability of wholesale design change is very small.
- 3.Each design phase (Conceptual, Schematic, Design Development, 50% / 100% Construction Documents) has a corresponding estimate prepared.
- 4.As each design phase progresses to the next, the level of documentation and information increases, the benchmark estimate should remain unchanged. The initial estimate, prepared in the early stages of the project, should equal the final bids.
- 5.Pre-Construction estimating uses historical data, knowledge of foundation and structure systems, experience, “rules of thumb” and the ability to fill the missing pieces as tools for preparing estimates to maintain continuity during the various design phases.
