Outsourced estimating can help contractors maintain bid activity while internal teams focus on commercial review and project execution.
- Increase capacity during busy tender periods
- Obtain trade-specific measurement support
- Reduce repetitive takeoff workload
- Receive structured and reviewable deliverables
- Support preliminary budgeting and tender preparation
- Scale estimating support according to project demand
How It Works
A clear route from drawings to estimating deliverables
Project fees and delivery timing are confirmed only after the documents, scope and deadline have been reviewed.
Submit Documents
Upload drawings, specifications, schedules, addenda, site location and required deadline.
Scope Review
We identify the required trades, measurement detail, report format and project constraints.
Estimate Preparation
Our team measures quantities and prepares the agreed cost or takeoff deliverables.
Delivery & Clarification
You receive the completed reports and can raise questions about scope, assumptions or quantities.
Estimating Methods
The method should match the design stage and decision required
Spiron Engineering selects an appropriate estimating approach according to document maturity, scope definition and the intended use of the estimate.
Bottom-Up
Individual quantities and work items are measured and assembled into the overall estimate.
Top-Down
High-level benchmarks or comparable project information support preliminary budget decisions.
Three-Point
Optimistic, expected and pessimistic values can be used where uncertainty needs to be considered.
Parametric
Rates per area, unit or system can support early budgets where detailed design is unavailable.
