Special Inspection

We have staff qualified to provide the inspections required by the International Building Code.

Our special inspectors work under the direct supervision of the professional engineers within our materials testing department. Our testing and reporting protocols are tailored to the requirements of each local building official and the needs of the client. Our primary concern is to provide clear communication so that any deviations from the plans are addressed by the appropriate design professional and the project is completed in accordance with the project plans and specifications.
