Fort Meade, MD
Aaron Enterprises, Inc. was contracted to install 23,000 LF of 30” diameter HDPE conduit bundles for 230kV electric lines by HDD. The crossings were installed as three separate parallel installations ranging from 1,100 LF to 2,600 LF. Several environmentally sensitive features with a fixed inadvertent return (IR’s) disturbance area were crossed. AEI employed a comprehensive instrumentation program that successfully reduced the risk and impact of IR’s while drilling. See attached paper presented at the ASCE Pipelines 2017 Conference below for more details.
