COVID-19 Response

Dear P.W. Trenchless Community,

P.W. Trenchless is committed to providing its staff, clients, and greater community a safe working environment.

As British Columbia continues to reopen, we are committed to staying attentive to our core focus while adding additional procedures that will enable the following:

  • A return to the office – Our office in Surrey has reopened with the following safety measures taking place to ensure the safety of all:
    • partial occupancy limits,
    • implementation of policies for cleaning and disinfecting,
    • the training and supply of proper usage of PPE equipment.
  • On-site Work – As of April 14th the onsite crews will be adhering to new procedures to limit the risks of COVID-19, these procedures include:
    • Staying Home if you are ill or if you suspect you might become ill
    • Employers and workers will follow personal hygiene practices like frequent hand washing (hand sanitizing/wipes), avoid touching your face (including ears), coughing/sneezing into your elbow as well as removing yourself from the immediate area, and avoiding direct contact with others. Wear rubber gloves whenever possible
    • Practice physical distancing as much as possible (2 meters/6 feet). This includes toolbox talks or other daily meetings
    • If you must work within 2 meters (6 feet) of a person, wear your respirator. If you do not have one, work with someone who does, and you can wear a paper mask or other cloth covering to protect you from spreading the virus to others.
    • Do not sign the tablet after attending a meeting where you are required to sign (i.e. Daily Everything, safety meeting, other). The person with the tablet (Foreman/Designate) will include your name and mark an “X” or other symbol to confirm your attendance
    • Remove your coveralls at work. Do not wear them home. If you do, do not enter your home with them. It is best to remove your work clothes before entering your home to avoid possible contamination. It us suggested by hazmat professionals that you wipe down your keys, wallet, etc., and anything that you bring into your home from the outside.

These changes above are a result of many hours of work between management, due to the nature of the situation these changes will be fluid and can be expected to change based off the guidelines that the provincial health officials deliver.

During this time, I wish to acknowledge our Core Values of Company Commitment, Innovation, Pride in Work, Positive Attitude, and a Team Player. We will continue to display these values as we continue to put the community first.

Please do not hesitate to reach out to your contact at P.W. Trenchless or to David O’Sullivan if you have questions regarding these changes.

Design - Build

An alternate tendering process where the contract is awarded to one entity which comprises both engineering and contracting.

Because PW Trenchless Construction offers such innovative solutions for underground utilities, it is often beneficial for the owner to request solutions based on a performance specification. This allows PW Trenchess to offer unique solutions while working with equally innovative engineering companies. Learn more about design - build here!

Pipe Replacement & Rehabilitation

In this day & age of pipe systems reaching the end of their projected lifespan, pipe replacement and pipe rehabilitation have become major fields of engineering.

PW Trenchless Construction provides viable options such as pipe bursting, loose fit lining and internal pipe re-construction whether partial & fully circumferential. Learn more about pipe replacement & rehabilitation here!

More Info

Culvert Rehabilitation

The aging culverts under roads and highways in many case have reached the end of their engineered life-span. We consider the rehabilitation or replacement of these culverts to be vital to our built environment.

PW Trenchless has been a pioneer in working with MOTH, railway companies and municipalities in developing rehabilitation methodologies for the hundreds of thousands of culverts that currently exist in BC. We have offered solutions in both procurement and construction from design-build to sliplining, invert rehabilitation and full circumferential relining. Learn more about culvert rehabilitation here!

Point Repairs

Often pipe failure can be concentrated to one section, for various reason, leaving the rest of the pipe in good condition. The repair of these localized failures are know as external point repairs (EPR's).

EPR's demonstrate PW's ability to work as both a trenchless and civil contractor, completing EPR contracts using our civil contracting skills and assisting other pure trenchless contractors who only have the capacity to work in an existing pipe. Learn more about point repairs here!

Pipe Upsizing

Pipe upsizing is the fundamental concept of pipe bursting.

The vast majority of pipes are less than or equal to 200mm in diameter, but with today's densification practices of urban design, there is a major demand to increase current capacity to handle extra flow. Pipe bursting provides the ideal solution to this issue, particularly in an urban setting. Learn more about pipe upsizing here!

More Info

Horizontal Directional Drilling

Horizontal Directional Drilling is a low impact Trenchless construction service where pipe is installed in a shallow arc along a bore path which has been created by a drilling rig. Often the terms Horizontal Directional Drilling (HDD) and Directional Boring are used interchangeably, but in our industry we use the word “boring” when we utilize smaller sized drilling rigs with small diameters for short crossings in the hundreds of feet, and we use the word “drilling” when we utilize larger rigs with large diameters for long crossings in the thousands of feet. Learn more about horizontal directional drilling here!

More Info

Primus Lining

Primus Line® is a flexible sliplining solution for the trenchless rehabilitation of pressure pipes. The system consists of a flexible Kevlar® reinforced liner and specially developed end fittings. Primus Line® is not bonded to the host pipe and is self-supporting. An annulus remains between Primus Line® and the host pipe.

Developed by experienced engineers, the system is suitable for different media as well as various application needs and has already proven itself in numerous projects.Learn more about primus lining here!

Join Our Team

When you join PWT, you become part of a community of people who are engaged in the most innovative practices in the Trenchless Industry. We have been instrumental in setting up a scientific method for cities to gain carbon offsets/credits from their use of trenchless construction. This system has been reviewed by the BC Government and has been approved as of December 2018. We expect to see it in common use shortly.
