Project Profile: Little Gunpowder Bridge

New Office: CCGI has recently moved to new facilities giving us better

resources to meet our clients needs. These facilities include 5 acres of yard,

15,000 SF of warehouse and 6,000 SF of shop space.

Solar Projects: CCGI has expanded its equipment re-

sources for installation of ground mount solar systems in all geo-

technical conditions while maintaining the high level or produc-

tion required.

System: Grouted Cased Micro Piles Owner: Baltimore County, MD

Foundation Issue: In order to reconstruct the bridge for US 1 over Little Gunpow-

der Falls, 225, 8 3/4”micro piles, with a capacity of 70 tons were needed to support

the structure.

Special Conditions: Close proximity to protected waterway and access to abutments

created difficulties for size and location of drilling equipment. In addition, an abun-

dance nested boulders presented challenges to the drilling process.

Solution: CCGI provided a design build solution utilizing micro piling. The system

was proven through an extensive test pile program. CCGI used a specialty over-

burden system to manage the drilling process through the nested boulders. This sys-

tem allowed CCGI to advance casing to the required embedment into the bedrock

below the boulder layer. In order to overcome the tight access conditions CCGI im-

plemented a Cassagrande

M6A-1 to drill the test

and production piles.

CCGI considered many

systems for the installa-

tion of these piles, but the

maneuverability and capa-

bility to drill through the

nested boulders with the

micro pile system held the

advantage over any alter-

native method.
