Heavy Rigs

How long has The Crossing Company been in business?

The Crossing Company was established in 1997 and set out to become the industry leader in Horizontal Directional Drilling. We have combined industry leading personnel with equipment specifically designed for the Canadian climate to complete some of the most challenging projects in Canada.

How many rigs are in The Crossing Company's heavy rig fleet?

Please refer to the Heavy Rig Inventory by clicking here.

How many loads are required to mobilize a heavy rig?

Our rigs range from 7 - 20 standard oil field loads depending on the size of the rig and the project specific equipment requirements.

What size of pad is required for a Crossing Company heavy rig?

The average pad size required for a Crossing Company rig is 40m x 60m with the rig located near the centre of the pad. This pad size is actual work space and does not include the spoils.

What is the success rate for HDD projects?

Our success rate across all of our divisions is 98.75%

What is an "intersect"?

An "Intersect" is a technique in which two rigs, positioned at each end of a crossing, drill towards each other. One rig drills into, or intersects, the pilot hole created by the opposite rig. After the intersect, one rig withdraws from the pilot hole, while the drill string from the opposite rig chases it to other end of the hole. Reaming operations can then be conducted with both rigs working in tandem, or the ream can be conducted in a conventional fashion using one rig only. The product line is pulled in using one rig.

Do the heavy rigs work 24 hour shifts?

Yes, all heavy rigs work 24 hours a day, seven days a week. There are 5 men per shift and there are two twelve hour shifts per day.

How does The Crossing Company steer a job? How accurate are the steering tools?

The Crossing Company uses Tensor Steering Tools and Vector Magnetic Steering Tools positioned behind the drill bit in conjunction with Direct Current and Alternating Current electromagnetic coils on surface. The Tensor tool has a stated accuracy of 0.1° Inclination and 0.25° Azimuth. The Vector Steering Tool has a stated accuracy of 0.1° Inclination and 0.4° Azimuth. The stated accuracy of the electromagnetic coils is 2% of the coil to bit vertical distance.

How far can you drill?

Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for horizontal directional drilling is 3,000 m.

What type of drilling fluid (mud) do you use?

Each drilling fluid program is project specific and is designed by a mud engineer. Most systems consist of a bentonite base and have a variety of polymers and additives added to the base system depending on the geotechnical conditions and the desired outcomes.

Light Rigs

How many light rigs are in The Crossing Company’s light rig fleet?

Please refer to the Light Rig Inventory by clicking here.

How many loads are required to mobilize a light rig?

Depending on the light rig size the number of loads ranges from 3 to 7.

What size of pad is required for a light rig?

The typical spread sets up on a footprint of 10m wide by 30m long. This includes the drilling rig, support truck, drill stem trailer, and water truck.

How long does the rig take to get setup and ready to drill?

With adequate access for large trucks, the rig can be set up and ready to drill in under an hour.

What is your production rate?

Production rates vary based on the geological formation and size of the product line. It is reasonable to setup, drill and pull in 400m of pipe in one 12 hour shift.

What is the largest project LRD has completed with respect to hole diameter and total length?

The Crossing Company LRD has successfully completed reams as large as 1067 mm (42") in diameter and lengths up to 900m.

Does The Crossing Company LRD work 24 hour shifts?

We typically work 12 hours a day, seven days a week.

How does The Crossing Company LRD steer a job?

We have two different types of steering systems, "walkover" and "wire line".

What type of drilling fluid do the light rigs use?

The light rigs use a bentonite based mud system.

Auger Boring

What size casing or pipe can you install?

Kamloops Augering & Boring Ltd. has equipment and techniques to install casing/pipe from 25 mm (1”) to 3,658 mm (144”).

How long of a crossing can be completed using Auger Boring and Pipe Ramming techniques?

Crossing lengths are determined by pipe diameter, total crossing length and geotechnical conditions. Typically crossing lengths for these methods are between 10m to 140m.

What type of ground conditions can you ‘Bore’ through?

There is a trenchless construction method for all ground conditions. A comprehensive geotechnical investigation is critical to selecting the right method and managing the associated risks.

Can a crossing be completed if the project site has high water table?

Yes a crossing can be completed if the project site has a high water table. Our group of companies has extensive experience constructing shafts, dewatering and managing artesian wells. The dewatering techniques are specific to the trenchless construction method. Water tight shaft construction using steel or concrete, pressurized TBM systems and rotating heads are just a few of the methods employed to manage water.

How accurate can the crossing be in terms of line and grade?

Using the Guided Boring Machine, we are able complete a crossing up to 120m within 25mm of accuracy at a specific % grade.

When crossing a road or railway, do I need a traffic management plan?

Typically, we are able to complete a crossing under an active railway or major highway without any traffic disturbance. Because our techniques never leave a void in the ground there is no safety risk to motorist, railcars, or our crew. Our techniques are only displacing up to 2” of material around the leading edge of the casing, there is little risk of settlement or heaving.

How long does it take to complete a crossing?

A crossings completion depends on a number of factors including but not limited to: ground conditions, casing size, crossing length, weather, working conditions, line and grade requirements and any unforeseen obstructions encountered. Typically, when planning a project we use a production rate of 12-18 meters per day.

How much room do you need auger boring set up?

Most trenchless installations require a minimum jacking pit of 11m x 3m plus room for excavators and equipment lay down, however, if a site allows for it, a longer set up site does allow us to install longer sections of pipe which means less welding and a quicker completion of your project.

How much does it cost?

The cost of a project is all dependent on the crossing length, casing diameter, ground conditions, site location and complexity of the project.

Tunneling

How much time is required to mobilize a tunneling unit?

Approximately 2-3 weeks is required to prepare and mobilize a tunneling unit. Each tunneling unit is specifically modified for each project.

How much time is required to complete shaft construction?

The schedule of shaft construction varies based on the size of the project. The shortest amount of time would be 1 week and on larger projects could be 6 weeks.

How is tunneling impacted by sub surface obstacles? (i.e. boulders, buried debris, etc.)

Tunneling allows for access to the tunneling face itself. Obstacles that can’t be processed by the machine can be dismantled and removed by hand.

How do you manage groundwater?

Water tight shafts, pressurized tunneling systems and dewatering programs are all different methods of managing groundwater.

What is an achievable length for pipejacking and micro tunneling?

Up to a 1,000m is achievable using pipejacking and micro tunneling.

Are tunneling systems steerable?

Yes tunneling systems are steerable on the X,Y,Z axis. Steering is impacted by geotechnical conditions and pipe size.

How accurate is tunneling?

Tunneling accuracy is within +/- 5 cm

What is the necessary ground covering?

A rule of thumb for determining the necessary cover for tunneling is 1.5 times the diameter of the tunnel. For example if the tunnel is 1.2 m in diameter than the recommended amount of cover would be 1.8 m.

What is estimated production for tunneling?

Tunneling production rates can be up to 50 m per 24 hours.

What diameters are possible using pipejacking or micro tunneling methods?

Up to 3000 mm is common.
