Commercial construction inspections are more complex than residential draw inspections, and the gaps in a monitoring program become more expensive when the project is a medical office building, a mixed-use retail podium, or a ground-up warehouse than when it is a wood-frame apartment building. The complexity isn’t just in the building itself, though commercial projects do involve more sophisticated MEP systems, more specialty subcontractors, and more regulatory compliance layers than residential. The complexity extends to the draw documentation, the schedule of values structure, and the cost-to-complete methodology that a competent commercial inspection program must apply.
What Makes Commercial Inspections Different
Commercial construction involves a broader range of building systems than residential multifamily, systems whose installation quality and completion percentage are harder to verify visually than wood-frame progress. A concrete podium that is 60% complete looks different to an experienced commercial inspector than to one whose primary background is residential. Curtain wall installation progress, MEP rough-in status on a commercial floor plate, and the completion percentage of a commercial kitchen buildout each require trade-specific knowledge to assess accurately.
The schedule of values for a commercial project is also typically more complex than multifamily. Commercial schedules often include tenant improvement allowances, shell completion milestones, and systems completion benchmarks that are structured differently from the standard residential trade categories. An inspector reviewing a commercial schedule of values needs to understand the distinction between shell completion and tenant improvement completion, because the percentage claimed against the shell contract tells lenders something very different from the percentage claimed against the TI allowance.
Key Commercial Scopes That Require Specific Inspection Attention
Structural steel and concrete. Commercial buildings frequently use structural steel frames or concrete structures that require specific inspection knowledge. Post-tensioned concrete floor systems, common in parking structures and high-rise commercial, have specific strand layout, tensioning sequence, and pour requirements that an inspector without post-tension experience cannot effectively evaluate. The special inspections required for these structural systems must be coordinated with the monitoring program so that the monitoring inspector and the special inspector are both tracking completion of structural milestones.
Curtain wall and exterior envelope. Commercial buildings with glass curtain wall systems are being inspected on a progress metric, what percentage of the curtain wall is installed, that is meaningless without understanding the curtain wall’s installation sequence. Curtain wall installation proceeds in phases: structural attachment, framing, glazing, and sealant. Each phase has its own completion metric. An inspector who reports “curtain wall 60% complete” without breaking down what phase is complete is not providing the information lenders need to evaluate draw accuracy.
Building management and control systems. Commercial buildings include building management systems (BMS) that control HVAC, lighting, access control, and fire alarm functions from a central platform. BMS installation is typically one of the later MEP scopes to complete, and its completion often cannot be verified until the systems it manages are themselves complete. Lenders should understand that BMS percentage of completion claims are inherently harder to verify than rough-in MEP progress.
Tenant improvement coordination. For commercial projects with multiple tenants, TI buildout proceeds on different timelines for different tenants. An office building where the base shell is complete but only two of six tenant suites are built out is a project whose occupancy, and therefore whose ability to service its permanent loan, depends on the TI program completing on schedule. Monitoring programs for commercial projects with tenant improvement components should track TI progress by tenant, not just as an aggregate percentage.
Documentation Requirements for Commercial Draws
Commercial construction draws typically involve more complex documentation than residential. The draw package for a commercial project commonly includes contractor pay applications on AIA G702/G703 forms, subcontractor pay applications that must be reviewed against the GC’s schedule of values, stored materials claims with delivery documentation, and lien waivers from the GC and each major subcontractor.
The AIA G702/G703 format, widely used for commercial construction payment applications, provides a standardized structure for the schedule of values and completion percentage claims. Lenders financing commercial projects should require that draw packages use this format, because the G702/G703 structure makes it easier to verify that claimed percentages are consistent with the inspector’s field observations.
Stored materials claims are more common in commercial construction than residential, because commercial projects often procure major equipment items, HVAC units, electrical switchgear, elevator equipment, well in advance of their installation. Stored materials claims require documentation confirming that the materials are actually on site (or at an approved off-site storage location), that they are insured, and that they are segregated for this project. Monitoring programs that accept stored materials claims without this documentation are creating draw fraud exposure.
Cost-to-Complete for Commercial Projects
Cost-to-complete analysis for commercial projects requires trade-specific knowledge of what the remaining work actually costs. A commercial MEP system that is 70% complete by the contractor’s claim may have more or less than 30% of its total cost remaining, depending on which phases of the installation are complete. MEP rough-in (the in-wall phase) typically represents 40% to 50% of the total MEP contract; trim-out and commissioning represent the balance. An inspector who doesn’t understand this distribution will produce a cost-to-complete estimate that is systematically wrong.
Commercial construction inspection requires inspectors who understand the specific project type being built, because office, industrial, retail, healthcare, and data center construction each have different MEP density, different commissioning requirements, and different certificate of occupancy complexity that a generalist inspector is not equipped to assess accurately.
Commercial construction lenders who engage inspection firms with product-type-specific experience, rather than general commercial inspection capacity, receive reports that reflect genuine understanding of what correct progress looks like for the specific project type being monitored. The difference between a well-prepared commercial construction inspection report and a generic one is the difference between useful intelligence for draw decisions and documentation that confirms the site visit happened.
