For over 20 years, Thielsch Engineering has been performing construction testing and inspections throughout New England. Along with the nondestructive examinations involved in our testing of buildings and bridges, our knowledgeable professionals are distinguished by their expertise in “Special Inspections” of critical structural material.

We perform pre- and post-assessment evaluations of buildings, weld repairs of various deficiencies, and vibratory testing of bridges and buildings utilizing specific vibratory equipment and strain gauges. In addition, we have the capability to extract concrete and steel samples for various types of laboratory testing. Our construction testing is performed both in the field and at our A2LA-accredited in-house laboratory. Our expert personnel ensure that all work is performed in accordance with the applicable ASTM and/or DOT specifications.
