Professional Third Party Estimating Services
Construction estimates can vary because of differences in scope interpretation, quantities, labor assumptions, material pricing, equipment requirements, and project conditions.
Depending on your requirements, we can provide:
- Independent cost estimates
- Estimate reviews
- Quantity verification
- Material takeoff reviews
- Cost comparisons
- Scope comparisons
- Labor quantity reviews
- Bid comparison support
- Budget reviews
- Trade-level cost reviews
- Change-order reviews
- Drawing-based cost verification
- CSI division reviews
- Second-opinion estimates
The scope of the review can be tailored to an individual trade, selected project components, or a broader construction estimate.
Independent Estimating Review
An independent estimating review provides a separate assessment of an existing estimate using available project drawings, specifications, schedules, and supporting documents.
The review can help identify differences involving:
- Material quantities
- Scope coverage
- Unit costs
- Labor assumptions
- Equipment allowances
- Missing scope items
- Duplicate items
- Trade classifications
- Allowances
- Bid inclusions
- Bid exclusions
- Construction divisions

Third Party Cost Verification
Our third party cost verification services can help project stakeholders evaluate whether construction costs are reasonably aligned with the scope and information provided.
Cost verification may include reviewing:
- Material pricing
- Labor costs
- Equipment costs
- Installation costs
- Quantity calculations
- Trade breakdowns
- Allowances
- Unit pricing
- Vendor pricing, when provided
- Subcontractor pricing, when provided
- Change-order costs
- Overall construction budget
The level of verification depends on the documents, estimate detail, pricing information, and project scope available for review.
Second Opinion Construction Estimate
If you already have a construction estimate but want another perspective, a second opinion construction estimate can provide an independent comparison.
A second estimate may be useful when:
- Two contractor estimates differ significantly
- A project budget has increased
- You want to verify quantities
- You need another view of anticipated costs
- A bid appears unusually high or low
- The project scope has changed
- You are evaluating a major renovation
- You need additional information before making a construction decision
- A change order requires review
- You want to compare an existing estimate with an independently prepared estimate
Our team can develop an estimate from the available construction documents and compare relevant findings with the information you provide.
External Estimating Services
Our external estimating services provide an additional estimating resource outside your existing project team.
External estimating can be useful for:
- Project owners reviewing contractor pricing
- General contractors reviewing subcontractor bids
- Developers validating project budgets
- Construction managers reviewing trade costs
- Contractors checking internal estimates
- Design teams evaluating project costs
- Project teams reviewing change orders
- Stakeholders comparing multiple bids
The purpose is to provide organized estimating information that can support your internal review and decision-making process.
Third-Party Quantity Takeoff Verification
Cost differences often begin with quantity differences. Before evaluating pricing, it can be useful to verify the underlying takeoff.
Our quantity verification services can review or independently calculate:
- Square footage
- Linear footage
- Cubic quantities
- Material counts
- Assembly quantities
- Equipment counts
- Fixture counts
- Structural quantities
- MEP quantities
- Sitework quantities
We can compare independently developed quantities with an existing takeoff to identify significant differences requiring further review.
