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.
