A legacy from over 50 years.
Our History
Founded in 1974 by Glen Sandwith, GS Construction has a proven track record of success and growth, and continues to look ahead without forgetting the robust past.
Pre GS Construction – A History of Glen
In 1963 Glen was working for the New Brunswick telephone company as a field inspector for the installation of utilities by contractors. It is there that he learned the details of contract management, payment clauses and scope of work in contracts. On one project he realized that the contractor was doing extra work outside of the contract scope and went to bat for them in getting paid for their extra work. The contractor was EW Farris who he would later go to work for. He then started doing design work on subdivisions for shallow utilities. He didn’t know it at the time but the seeds were laid for being in construction and being a contractor.
GS Holdings is Founded
Glen started GS Holdings June 4th, 1974. The reason he named the company G.S. Holdings was that he wanted to keep it a secret that he was going out on his own. He had been working for Poole Engineering at the time as a Superintendent. His brother-in-law, John Oxner, was also working at Poole and helped start GS with Glen as an estimator.
The first crew consisted of Leon Banhiuk as Pipelayer, his younger brother Matt Bahniuk (who later went on to start Streamline Construction with Ken Allen. Glen helped them get bonding on their first project), Gerry Thurd, and Glen's younger brother Stan
First Project, GS1
The first job Glen bid on was for the Town of Hinton. It was advertised in the paper at that time. Glen had $1500 in savings.
In order to bid on the project he needed bonding which he couldn’t get on his own. His older brother Gordon knew Ivan Gwynn who was the founder of Northern American Construction (still in operation as a public company), from working on the South Saskatchewan dam where Glen had worked back in 1964. Ivan did not know Glen but Glen phoned him up and asked him ‘if he would like to make some money’. To which Ivan replied, ‘Sonny that is what it is all about.’ For 10% of the contract value Ivan agreed to bond GS as long as it was approved by his estimator. Reid Carruthers looked it over and added $100k. The bid was $420K with the second bidder being at $485k. When the job was finished GS had made $120k in six months.
A Second Crew
After making money from the first job Glen decided to start a second crew in 1975.
Storm Pond & Lift Station
GS undertook a storm pond in Acheson GS2 and a lift station in Camrose GS3.
Camrose
First truck. The lift station. There were two 8 inch submersible pumps that pumped into one force main that went down across the creek and into another manhole. And also along with that was an eight inch siphon line so that if the pumps couldn't keep up, the siphon line may come in and it could move as much water as one of the one of the pumps.
Nisku Industrial Park, SW of Beaumont
Here's a waterline going across the from Nisku industrial park over to a residential area on crossed the creek that line.
The Notorious Competitor
A notorious competitor tried to mess up GS’s bonding. Glen bid a job in Whitehorse (1976-77) and this competitor kept telling his bonding company that GS was going broke on the job. Both crews were up there and Glen bought a 245 CAT excavator (equivalent to 670 today) and shipped it up there to do the job.

Hard Times & a Lucky Win
In 1980, GS had no work to start the season but then got a job in Slave Lake. As soon as the first payment came in the Bank seized the payment which would force Glen to declare bankruptcy. He had not breached any covenants of the banking agreement and so if had been put into bankruptcy he could have sued for future lost profits. His lawyer wanted to sue for $20 million. The bank finally relented, and Glen only asked that his vendors were paid and an apology letter sent to them. His name and reputation was more important than declaring bankruptcy. He continued at the bank until he paid off the loan he owed and left the bank in 1982.
During the tough 1980s, Glen did the estimating, paid bills, ran the main excavator and even laid pipe as needed during those lean years. All the while working in remote towns and hamlets in Northern and Central Alberta.

The pipe was laid with the help of a helicopter, as it went down in the river bank. Glen used a helicopter to drop and install all the pipe down the edge of the Pembina River. Glen was always trying to figure out how to construct projects in unique and more efficient ways. He always loved the risky and unique projects.

A Better Future
The 1990s started to get better. With John returning as the estimator after a 10 stint working in Calgary, and Jules Bertrand coming to work for Glen as a Foreman around 1996 after spending 33 years with Standard General. This slowly allowed Glen to take more of a management role and take some of the burden off of him.
The Home Office
In 1990 Glen finally completed his house on the acreage and was able to put his office in the house. He had purchased the acreage in 1979 with plans to build his dream home. Those plans had to wait 10 years.

Running the Crews
From 1998 to 2004, GS had one main underground crew under Jules and a second crew run by Wilf Hartfelder, a good friend of Glen’s who had retired from CN. Wilf who could do underground but also earthworks, landscaping and other special projects.

A Second Underground Crew
In 2005, GS started a second underground crew with Terran running one and Mark Wright running the second. Wilf Hartfelder was running a third crew doing earthworks and special projects. Again, at that time Mark and Terran would both be wearing different hats at times by also going and laying pipe or running a piece of backfill equipment while also playing our role as Foreman.

Wilf Exits the Company
In 2006, Wilf Hartfelder left the company after the 2006 construction season to start his own landscaping business.
New Blood
Steve Brittain was soon hired to run the second crew. Steve had been an engineering inspector with UMA. He later returned to a group of engineers who started Select Engineering. Terran was able to become more of a project manager. Again at that time everyone was wearing different hats.
First Meeting
In 2006, Ryan Thompson met Glen, Terran and Mark for the first time as an inspector for Associated Engineering on GS 208 – 2006 Sewer Bypass Project. Ryan would work with GS on several projects as the consulting engineer over the next few years in Onoway, Slave Lake, and Hinton.
Unprecedented Economic Growth
From 2006 tp 2008, Alberta saw unprecedented economic growth. It was a crazy boom with oil prices reaching the $150/barrel. It was like the ‘wild west’ and it was hard to find people to fill jobs with all the work that was available. During those years GS was able to do very well in their niche of municipal rehab because no one wanted to do these difficult and high risk projects when there was ‘easier’ work to be had.
A Large, Unique & Risky Project
The Sucker Creek Water Intake project, started in 2007, was one of the most unique, riskiest and biggest projects GS had done to that time. The key to its success was Glen… he designed the techniques and tools and strategies that were used to put a water line 1.4km out into Lesser Slave Lake. It was a very successful job financially because of the construction methods that were used and it enabled GS to ‘weather the storm’ of the later financial crisis of 2009 and 2010.

2 Underground Crews
In 2008 GS continued to run 2 underground crews.
Mike’s First Project
Mike ran his first project as a Foreman running his own crew in Onoway and under the tutelage of Glen as well.
A Loss in Revenue
Revenues were cut by 60% due to the Global Financial Crisis and revenues didn’t recover to 2008 levels until 2012. However, GS maintained two crews, stayed profitable and didn’t have to let go any of its permanent or key employees.
A Contract with EPCOR
In 2012, Ryan Thompson and Terran spoke about potential opportunities with Ryan coming on board with GS. At that time GS was looking to get a long term contract with EPCOR Water so the timing was perfect. Ryan was hired and spearheaded the proposal to EPCOR Water and secured the contract. He then proceeded to build out the team and infrastructure needed to service such a large contract. This was a catalyst for GS in providing it with steady revenue and allowing it to grow.
5 Underground Crews
2015 GS was running 5 main underground crews and 3 mini or support crews.
The Collapse in Oil Prices
In 2016 revenues were cut in half from 2015 due to the collapse in oil prices and did not recover to 2015 levels until 2018. Again, GS stayed profitable and didn’t have to let go any of its permanent or key employees.
7 Underground Crews
In 2017, GS began running 7 main underground crews.
