Locating Buck Outs and Cores with Ground Penetrating Sonar

Scope:

Graham Residential
McKinstry
CECO
DW Close

This project was a unique challenge, as it provided numerous opportunities for our skills to be put to the test. SRI was an intregal part in relocating 104 buck-outs, and 100+ cores. Many cores and buck-outs were in close proximity to columns.

This picture has two 4" cores cutting through rebar avoiding the post-tension cable in red

With some critical areas being placed next to a column, we were presented with unique set of difficulties to overcome.

In this image is the stud rails, top steel (black), banded and distributed cables (red), with two 4" and one 2" core in the midst.

SRI pays great attention to details, accurately displaying what is in the slab.

Cables are in red and plastic conduit along with j-boxes are in orange

This is the underside of the same floor, with the j-boxes reveled slightly in the concrete

These pictures show the benefit of using SRI and ground penetrating radar (GPR). Their accuracy and mobility are unbeatable.
