Projects to build and expand broadband networks often bring construction to established neighborhoods, challenging project owners and contractors to build underground networks with minimal disruption of routine activities and limited surface damage.
Extending broadband services to more customers is a priority for telecommunications and cable television companies who are locked in a fierce battle to consolidate and expand their shares of the high-speed Internet market and, with it, other bundled services; fiber optic technology is a key element
Horizontal directional drilling (HDD) is an innovative “trenchless” construction procedure. It has been in use for a dozen years to make trenchless installations of cable, conduit and duct in areas where surface improvements or crowded utility easements make excavation impractical or impossible.
Earlier this year, routine activities came to an abrupt halt at San Bernardino Valley (Calif.) College when a construction crew excavating with a backhoe struck a power cable, causing a small explosion that knocked out a campus transformer.
If you’re reading this, chances are you have enjoyed the sense of accomplishment that comes from driving an 8-foot long, mostly steel rod into the earth and connecting a ground wire to it. It’s tough work.
Utility providers routinely bury electrical and communications cable and the conduit in which cable is placed for protection. And for years, trenching and vibratory plowing were the primary methods contractors used for underground construction.
