In construction, quality assurance goes far beyond visual checks. Every phase, from excavation to finishing, must meet design, safety, and regulatory requirements. That’s where a work inspection request (WIR) comes in.
A WIR is a formal checkpoint in the construction process. It ensures that completed work is inspected, verified, and approved before the project moves forward. Whether you're building a commercial high-rise, an industrial facility, or a transportation hub, the WIR process ensures accountability at every critical milestone.
In this guide, we’ll break down everything you need to know about Work Inspection Requests in construction—what they are, why they matter, who’s involved, and how to manage them efficiently.
A WIR is a formal document submitted by the contractor to the supervising consultant or engineer to verify that specific portions of the completed work comply with project specifications, drawings, and approved materials.
It serves as a mandatory checkpoint for quality verification before moving to the next phase of construction or before including completed work in an interim payment certificate (IPC).
Each WIR references:
Once submitted, the supervising consultant or engineer performs a visual and technical review. If the work meets all requirements, formal approval is issued. Only then can the contractor proceed to the next phase or claim the completed scope for billing.
Construction requires coordination between multiple trades, vendors, and timelines. Missing a key inspection can lead to:
A work inspection request formalizes the contractor’s readiness for inspection. The outcome, whether it’s approval or rejection, is documented, which protects everyone involved and builds traceability into the project.
Here’s how a WIR in construction supports several critical areas:
Lifecycle project management tools like PMWEB streamline the WIR process by enabling centralized tracking, standardized forms, real-time status updates, and secure document control—all within a single integrated platform.
The WIR process plays a vital role in controlling quality and progress on-site. It structures how inspections occur at critical stages, such as Hold Points, which require stopping work for approval, and Witness Points, where the engineer observes but work may continue without their presence.
At its core, a WIR is a formal mechanism that initiates quality verification at critical stages of the construction process. It introduces a pause in the workflow, prompting an inspection before moving forward to subsequent tasks. This ensures that each stage is built upon verified, compliant work, reducing the likelihood of rework or cascading errors.
Specifically, a WIR confirms that:
Several parties play an active role in the WIR process. Let’s break them down:
A complete and well-structured WIR in construction includes the following essential components:
Basic details like project name, contractor name, WIR number, and location of the work to be inspected.
A concise description of what work is being presented for inspection. e.g., “Formwork and steel reinforcement for ground floor slab, Zone A.”
Includes all relevant drawings, specifications, method statements, or approved shop drawings. These references help the inspector verify if the work is compliant.
This defines the type of inspection:
The proposed date and time for the inspection should be confirmed, allowing the consultant to schedule and prepare accordingly.
The WIR process follows a clear sequence of actions to keep inspections organized and effective. Each step involves specific tasks and responsibilities that move the project forward without surprises.
As soon as a portion of the work is completed, the contractor or QA/QC personnel prepares the WIR. This involves:
Verify the inspection date with all stakeholders to ensure no delay.
The consultant reviews the submission thoroughly, comparing the work against project standards and codes. They conduct a site inspection when required and assess whether the work meets contractual requirements.
The consultant then provides formal feedback, either approving the work or requesting corrections.
The engineer will then review the WIR and compare it to:
They can request clarification, reject it, or accept it with comments in case of minor corrections. In case of rejection, the contractor will have to reply to all comments, make corrections, and resubmit the WIR. This step prevents substandard work from progressing and maintains quality control.
Based on findings, the WIR is:
If rejected, the contractor must address all comments, correct issues, and resubmit the WIR. This step prevents substandard work from progressing and maintains quality control.
Each result is dated and signed either digitally or in person.
Every WIR becomes part of the project record. These entries help with:
Keeping a WIR log provides managers with insight into inspection patterns and areas that require attention.
With the right tools and practices in place, you don’t just catch errors, but also build confidence into the project from the ground up. As a lifecycle project management software, PMWEB provides your team with complete control over the WIR process, from initiation to closeout. Here are some of its key features:
PMWEB inspection checklist for exterior insulation and finish systems
The visual form builder lets you create project-specific WIR templates tailored to each trade, discipline, or system. You define checklist items based on contract requirements, codes, and approved drawings, down to individual inspection items for systems like electrical, mechanical, or structural.
Each template includes fields for specification references, inspection status, and remarks, ensuring there is no ambiguity about what was inspected or why.
PMWEB safety checklist for electrical inspections with hazard analysis and PPE review
All WIRs can be accessed directly from mobile devices on-site. This allows your team to capture photos, videos, and field data in real-time and attach them to the inspection request. The assigned workflow routes the WIR to the consultant, who either approves it or sends it back for correction.
PMWEB WIR dashboard showing performance metrics by inspection type and contractor
You also get a full performance dashboard built from WIR data. It logs every inspection by division, location, or contractor and presents trends visually. You can modify the layout to meet your reporting standards or client requirements without needing separate tools.

Beyond WIRs, PMWEB also supports Material Inspection Requests (MIRs). You can create separate forms to track material deliveries, storage conditions, manufacturer details, and compliance with technical specifications. All inspections, approvals, and related documents are stored in one system, providing a central source of truth for quality control.

Project owners also use PMWEB’s Scoring Tool to evaluate inspection outcomes or decide whether to advance projects through stage gates. You can build weighted scoring models, define criteria, and apply them across your portfolio. For BIM-enabled workflows, PMWEB integrates with Autodesk Revit, where you can link customized scoring to model elements and track completeness.

Once the work inspection request is approved, the contractor proceeds to the next activity. The signed WIR is archived as an official record confirming that the inspected work meets project requirements.
The contractor or the designated QA/QC (Quality Assurance/Quality Control) personnel is responsible for raising the work inspection request after completing a defined scope of work. They prepare the form, attach the required documents, and submit it for review by the supervising consultant or engineer.
A work inspection request is required for all activities identified in the project’s Inspection and Test Plan. These typically include critical tasks tied to structural, mechanical, electrical, and code-related work.
