OUR SERVICES

 

HDD Design

Feasible HDD designs for underground utility crossings. We develop HDD designs that combine geometry, ground conditions, utility constraints, pipe stresses and construction methodology into one clear engineering solution. Our design process includes feasibility assessment, bore path geometry, depth of cover, minimum radius, pipe stress and pullback checks, drilling fluid considerations, risk identification and construction recommendations. The result is a technically sound and feasible HDD design, ready to support safe execution.

Steps involved in HDD designing

The first step in designing an HDD profile is to clearly define the goals and objectives of the project, including the type and size of the pipe or conduit being installed and the desired drilling path.
A site assessment is conducted to gather information about the subsurface conditions and any potential challenges or risks that may be encountered during the HDD process. This may include collecting soil and geologic data, performing subsurface testing, and identifying any potential hazards or obstacles that may impact the drilling process.
The drilling path is carefully planned to minimize any potential impacts on surface structures, landscapes, and ecosystems, and to ensure that the drill can be effectively navigated through the subsurface. The drilling path should also be designed to avoid any underground utilities or other obstacles.
The type and size of the drilling equipment and materials required will depend on the size and complexity of the project and the subsurface conditions. It is important to carefully select the drilling equipment and materials to ensure that they are suitable for the project and capable of meeting the project's requirements.

HDD Execution Support

Field technical support for HDD execution and critical project phases. We provide specialized technical support during HDD construction to help clients and contractors manage technical challenges, reduce execution risk and improve drilling performance. Our support may include drilling fluid evaluation and optimization, HDD tracking support, drilling data review, equipment and methodology recommendations, troubleshooting during pilot bore or reaming, and technical guidance during critical construction stages. Services can be provided on-site or remotely, with the objective of improving penetration rates, reducing downtime and supporting successful HDD execution.
 
GYRO_MAPPING_SERVICES
 

Mapping & Verification of Underground Utilities

Independent services for locating, mapping and verifying underground networks and constructed HDD crossings, aiming to confirm the actual location and geometry of the facilities. The services provide 3D geographic information that includes verification of the depth and position of the HDD borehole or existing utilities, as-mapped design, assessment of deviations from the initial design, and technical investigation of problematic or disputed facilities.
