Frequently Asked Questions

Q: What is the largest Project Culy Construction & Power Services has ever completed?

A: In 2010, Culy Construction & Power Services undertook a $12.0M project with AEP and was able to successfully complete it on-time and on-budget. Whether the project is $500 or $5.0M, Culy Construction & Power Services has the expertise and experience to SAFELY complete the project "On-Time and On-Budget" (read the case study)

Q: What is directional drilling?

A: Directional drilling is a trenchless process whereby a series of rods are ‘piloted’ into the ground and guided along abore path with electronic tracking equipment providing real time roll, pitch, depth and azimuth information. The rods can be directed left, right, up and down to insure line and grade accuracy. At the conclusion of the pilot bore, the bore path is enlarged by a reaming process. The carrier pipe is then pulled back once the reams have prepared the soil to accept the carrier pipe.

Q: What considerations should be accounted for when designing a directional drill job:

A:Key considerations for a successful design include:
- a good geo-techincal report, (cobbles, sand, and dense gravels are not ideal soils)
- sufficient righ-of-way for staging the equipment and carrier pipe
- access to potable water for drilling fluid development

Q: What is auger boring?

A: Auger boring, often referred to as 'jack and bore', is a method of installation that simultaneously ‘jacks’ casing while rotating helical augers within the casing removes spoil. A cutting head is attached to the 'lead' auger and can protrude just ahead, sit flush, or sit within the casing depending on the job requirements.  Hydraulic jacks located on the bore machine in the sending shaft provide the thrust that push the casing thought the ground. The rotating augers carry the spoil to the back of the casing pipe for removal by excavator or conveyor. 

Q: What is hydro excavation?

A: Hydro excavation is a safe, non-destructive and cost-effective process that utilizes pressurized water to break up soil. The soil is then removed through an industrial strength vacuum into a debris tank. This process allows for safe and precise excavation, which requires less backfill and restoration, less labor and less environmental impact than traditional digging methods. Most importantly, hydro-excavation virtually eliminates the risk of damaging underground pipelines or utilities. Hydro-excavation is also commonly referred to as hydro-vac excavation, vacuum excavation, daylighting, water excavation, slot-trenching and potholing.

Q: How many hydro excavation trucks does Culy Construction and Power Services have?

A: Culy Construction & Power Services has five hydro excavation vaccum trucks for dispatch to our customers located in the greater Midwest.
