Onsite Testing Services

Onsite Testing & Inspection

Independent, in-situ verification of materials, coatings, and components to support safe installation, commissioning, and compliance decisions.

Why Onsite Testing & Inspection Matters

Site Decisions Require Site-Level Verification

Site acceptance without verification exposes projects to rework, delays, and escalating costs. Once materials are installed, errors become significantly more expensive to identify and correct.

Onsite testing eliminates this uncertainty. Portable verification at the point of installation confirms that delivered materials match specifications, that coatings meet requirements, and that installed components are fit for purpose—before commissioning proceeds.

When decisions must be made on site, testing must happen on site.

Testing Scope Overview

Onsite Testing & Inspection

This service group covers the full scope of portable testing and independent inspection activities conducted at your site:

In-situ material identification

Mechanical property verification

Coating inspection

Independent third-party inspection

PMI & Portable OES Testing

Portable material identification conducted at your site confirms that delivered materials match the specified grade—before installation proceeds. Using handheld XRF and portable OES instruments, we verify chemical composition directly on components, piping, and structural elements.
