Wisconsin Special Inspections: Ensuring Code Compliance and Structural Integrity

• The Regulatory Standard: Special Inspections are required to ensure compliance with the IBC Chapter 17 and approved construction documents. This involves both inspection (observation and engineering judgment) and testing (material analysis).
• Why It Matters: These inspections provide verification that the structural system conforms to approved construction documents at significant stages. Failure to properly coordinate these inspections can result in delays in Certificate of Occupancy issuance.
• Independent Compliance: To avoid conflicts of interest, the Special Inspector must be independent of the general contractor. Furthermore, a design professional in charge of the project cannot act as the special inspector for their own design. Intertek provides this necessary third-party independence.

We maintain the necessary accreditations to perform inspections across the following categories in accordance with Wisconsin Department of Safety and Professional Services (DSPS) guidelines:

• Structural Steel: Including high-strength bolting, welding, and nondestructive testing (NDT).
• Concrete Construction: Reinforced, pre-stressed/precast, and post-installed structural anchors.
• Masonry & Wood: Comprehensive inspection services for structural integrity.
• Fire-Resistance: Sprayed fire-resistant materials, intumescent coatings, and fire-resistant penetrations.
• Soils & Foundations: Including deep foundation integrity.

Navigating the administrative requirements for your project begins with the accurate completion of the Special Inspections form SBD-8102. This document is a mandatory element of your construction documents; once issued, it becomes a formal part of the Department-approved plans and specifications. To secure conditional approval, the Owner or Owner’s Representative must submit this form, which requires comprehensive project and personnel data. You will need to detail project identification, contact information for all responsible parties—including the Designer of Record and the Supervising Professional—and the specific credentials and contact details for your designated Special Inspectors. Furthermore, the form mandates a precise description of the items requiring observation and testing, as well as the defined inspection type and reporting frequency. Because this form requires signatures from all responsible parties prior to the submission of plans, Intertek acts as your partner in ensuring these details are accurate, complete, and ready for timely filing to keep your project schedule on track.

Success begins before the first shovel hits the ground. Our team facilitates and attends vital pre-construction meetings to thoroughly review the scope of Special Structural Testing and Inspection requirements. These meetings are essential for coordinating the participation of all stakeholders—including the Contractor, Building Official, Supervising Professional, Owner, and testing agencies—ensuring that every party is fully aligned with their responsibilities. By providing adequate notification and clarifying expectations early, we help you prepare effectively, streamline communication, and schedule services with precision to prevent costly project delays.
