Understand the Scope Before You Commit the Budget.
A construction estimate is only as useful as the information behind it. Drawings, specifications, measurable quantities, site conditions, material choices, labour requirements and exclusions all influence the budget. Premark Group can discuss estimate and BOQ-related support where it fits the agreed project scope.
An early-stage estimate is not the same as a measured tender BOQ or a final contractor quotation. The level of detail should be stated clearly, along with assumptions, provisional quantities, taxes, exclusions and the basis of rates used.
In scope
What estimation and BOQ support may include
- Reviewing project drawings, specifications and available site information.
- Preparing or coordinating a scope-based preliminary estimate, where agreed.
- Organizing quantity take-off or BOQ information based on the documents available.
- Making assumptions, exclusions and provisional items visible.
- Comparing contractor or supplier quotations against the specified scope.
- Coordinating clarification questions and tracking variations to the original scope.
Detail
What affects construction cost?
Project size and configuration, structural requirements, soil and site conditions, material specifications, accessibility, labour, equipment, external works, building services, taxes, location and timing can all affect cost. Market prices and hidden site conditions may change the final amount.
