Evaluating Concrete Volumes

Overview

Our client, a real estate developer managing a commercial project, was presented with a change order related to site improvements. This triggered a series of additional change requests from multiple subcontractors, many of whom had valid entitlement. One request in particular stood out due to its scale and potential cost impact.

The Problem: The Elephant in The Room

The site concrete subcontractor submitted a change order requesting nearly 100 cubic yards of additional concrete. This volume, equivalent to 10 to 13 truckloads, immediately raised concerns. After reviewing the revised drawings, this request did not align with our understanding of the scope. A change of this magnitude would typically involve the addition of major structural elements, not minor design adjustments.

Our Solution: Detailed Review, Quantity Verification, and Clear Documentation

We approached the issue with a structured and objective process:

Scope Clarification

We reviewed the original and revised drawings to understand the intended changes and how they affected the concrete scope.

Quantitative Analysis

We performed a detailed takeoff to compare the subcontractor’s claimed increase with the entitled and verifiable quantity.

Entitlement Review

We confirmed that while entitlement existed, it did not justify the claimed volume.

Position Documentation

We compiled a clear and concise position paper with side-by-side quantity comparisons, annotated drawings, and a logical explanation of the discrepancy.

The Result: Fair Resolutions and Cost Savings

Our analysis revealed that the actual increase in concrete volume was far less than the 100 cubic yards claimed. The discrepancy stemmed from a misinterpretation of the revised drawings and an overstatement of the affected areas. As a result:

• The change order was significantly reduced

• The subcontractor accepted the revised scope after reviewing our findings

• Our client avoided unnecessary costs while maintaining a transparent relationship with project stakeholders

Key Takeaway: Entitlement Must Be Supported by Accurate, Verifiable Quantities

Even when entitlement is valid, quantity claims must be carefully reviewed and substantiated. A disciplined, data-driven approach can protect project budgets and ensure fair outcomes for all parties involved.
