StructureScan by GSSI

StructureScan is used daily on job sites to provide the critical answers you need.

Project: Locate Conduit in College Library Floor
Di-Tech International, Winnipeg, Manitoba, Canada

Project:
1.	Locate conduit.
2.	Trace and mark it out over an 80-foot long curve approximately 4' to 6" from the edge of the slab to prevent damage to the conduit when drilling holes for anchors for a railing to be placed along the edge.
3.	Job to be performed while library is in operation, without disrupting normal operation.

2.	2.5 inches topping
3.	Wire mesh at 6" on center in topping
4.	Last minute conduit placed in topping
5.	Carpet over topping

Results:
	Time to complete investigation - 3 hours without inconveniencing customer.

Project: Westin Hotel, Detroit Metro Airport
GPRS, Sylvania, Michigan USA

One of the largest construction projects in the Midwest is the new $1.2 billion, recently completed McNamara terminal at the Detroit Metro Airport. For passenger convenience, a Westin Hotel was incorporated into the main terminal building.

Pace Mechanical, the mechanical contractor for the hotel, decided to use the new StructureScan technology to locate the post-tensioned cables prior to drilling.

The concrete structure utilizes post-tension cables for reinforcing. It was critical that these cables were not cut when making the penetrations in the floor for the various mechanical systems.

Matt Aston, of GPRS (Ohio Concrete Cutting) was called in to help locate the cables.

While scanning the area where a penetration is needed, the operator marks the locations of the post tensioned cables.		The mechanical contractor is able to drill the hole by staying away from marks, which represent cables.

"GPRS really took a heavy burden off of our shoulders and allowed us to drill these holes with ease. Without this service, we could not have drilled 125 holes without hitting any of these cables."

"I have looked at other radar systems," said Aston of GPRS. "Our StructureScan system from GSSI is clearly the best system on the market."
