2. HORIZONTAL DIRECTIONAL
DRILLING
HDD IS A TRENCHLESS METHOD FOR INSTALLING A
PRODUCT THAT SERVES AS A CONDUIT FOR LIQUIDS,
GASSES OR AS A DUCT FOR PIPE, CABLE OR WIRE LINE
PRODUCTS. IT IS A MULTI-STAGE PROCESS CONSISTING
OF SITE PREPARATION AND RESTORATION, EQUIPMENT
SETUP AND DRILLING A PILOT BORE ALONG A
PREDETERMINED PATH AND THEN PULLING THE PRODUCT
BACK THROUGH THE DRILLED SPACE. WHEN NECESSARY,
ENLARGEMENT OF THE PILOT BORE HOLE MAY BE
NECESSARY TO ACCOMMODATE A PRODUCT LARGER

REFERRED TO AS BACK REAMING AND IS DONE AT THE
SAME TIME THE PRODUCT IS BEING PULLED BACK

3. Horizontal Rock Directionally Drilling has proven itself over the last few
years to be a very effective technique for the installation of pipelines and
other utilities in sensitive or congested areas. This document provides best
practices and recommended procedures for the investigation, planning and
execution of an HDD installation for pipeline construction. It provides
guidance on the regulatory, environmental, geotechnical, risk, economics,
engineering, contractual and construction considerations that must be
evaluated prior to any final decisions to proceed with an HDD installation.
4. Increased use of HDD technology has resulted in associated equipment and labour costs being
spread over multiple projects, making individual projects more affordable.
