Pattullo Bridge Replacement Project – Underhill Geomatics

The Pattullo Bridge Replacement Project is currently undergoing a detailed design process and as you can see from the artist’s rendering the new bridge will have two in-river piers, reduced from the six piers the current bridge has in the river.  

Northwest Hydraulic Consultants (NHC) was contracted to build a 1/80 scale model of the existing Skytrain, Pattullo and CN Rail bridge pilings, on the river bed so that hydraulic impacts can be tested and evaluated on the new bridge pilings, as well as the upgrades to the CN railway pilings for earthquake preparedness. 

The model is representative of what water in the Fraser River will do in relation to the new bridge structures and tests various construction and environment scenarios. 

A summary of the process: 

  • NHC built the original model 
  • Underhill performed the initial 3D laser scan to determine the current state of the river bed to ensure it was accurate to as is data 
  • Then NHC added the new proposed structures and performs tests by flooding the model with varying water levels, current speeds etc.  
  • Our team at Underhill is brought in each time a test has been completed to scan the resulting changes to the river bed after the flow has been drained. The new data are transformed as a digital surface which is overlapped on the reference river bed to reveal the changes.  

Underhill has been scanning this model regularly for NHC after each test for 4 years now. You can see in the images the targets we place on the facility walls in order to precisely match each scan overlay to the previous scenarios and the baseline. As the bridge is currently undergoing design refinements, we cannot show the model in full detail, however it’s very interesting to see the effects each test has on the river bed and how our 3D scanning technology is being used to provide accurate data to NHC for their testing.

Underhill Remembers – The Inuvialuit Final Agreement (IFA) Survey

Our first historical survey feature for National Indigenous History Month is “The Western Arctic Claim – The Inuvialuit Final Agreement” Survey. The land claim is also referred to as the COPE (Committee for Original Peoples’ Entitlement) Claim. In 1984, it represented the first northern comprehensive land claim agreement between the Federal Government, the Government of the Northwest Territories, and the Inuvialuit and was only the second in Canada at the time. The Inuvialuit are the Western Canadian Inuit. 

Chris Cryderman remembers; “The camp pictured was the Horton River camp.  It was situated on a hill above “Underhill” Lake (we called it that because it was “U”-shaped).  The crew who were set up here were, William Robinson, Carl Friesen, myself, and pilot Steve Jaksie of Sunrise Helicopters in Inuvik.  The two tent trailers had been modified by Sunrise to be slung there by helicopter.  The pilot had to go light on fuel load, and strip down, just to get one off the ground.  The canvas work tent (dubbed the “Underhilton”) was brought in by a Twin Otter on floats, along with plywood, 2×4’s, fuel, and other camp supplies.  Fortunately the grizzlies stayed away from camp. It was warm during the day but so cold at night that I used to sleep with just my nose sticking out of my mummy bag. ”  

Initially, there was little involvement in the surveying process from the Inuvialuit people; lessons had not been learned at this time. The lack of participation was definitely an issue with the Indigenous people and that was heard. For future projects Natural Resources Canada demanded more participation from local people and businesses through the proposal process. As time passed and more contracts were let, local Indigenous involvement grew significantly providing the majority of the work done including surveying, guiding, helicopter support and maintenance, vehicle supply, hotel, food, camps, cooks, etc. As well it became a wonderful experience for some of our staff to work with, train and learn about the land and more about the Indigenous peoples themselves and their cultures.

International Women’s Day: Remembering Anne Barbara Underhill

The first International Women’s Day occurred in 1911, supported by over one million people. Today, IWD belongs to all groups collectively everywhere.

Anne Barbara Underhill

This year, the IWD theme is #EachforEqual: An equal world is an enabled world.

To celebrate women’s day we are looking back in Underhill’s 107 year history, and highlighting the daughter of one of Underhill’s founding partners:

Anne Barbara Underhill
Pioneering Woman Astrophysicist
June 12, 1920 – July 3, 2003

Anne Barbara Underhill was a Canadian astrophysicist. She was the daughter of one of Underhill’s founders Frederic Clare Underhill.

  • Anne was the only girl in a family of 5 children
  • She was awarded the Lieutenant Governors medal in high school for outstanding achievement
  • Her mother Anna (nee Creery) Underhill passed away when she was 18, and she assisted in raising her brothers while attending the University of British Columbia
  • Anne lost her twin brother Ronald in WWII in 1944
  • Ronald Island was named after Ronald Underhill. Next to Ronald Island is the Anne Islands which are named after Anne. These islands were part of the “Underhilll Island” survey done by JT Underhill and others in 1921
  • She graduated from UBC with a BA Hons in chemistry in 1942 and received her masters in physics and mathematics in 1944
  • Anne was one of 4 female researchers involved in Canada’s contribution to developing the atomic bomb (The Manhattan Project ) in Montreal
  • Anne continued study at the University of Chicago, receiving her Ph.D in 1948. Her thesis topic was multi-layered stellar atmospheres
  • She received two fellowships from the University Women of Canada
  • Anne specialized in the study of ‘early-type stars’ or ‘OB stars’, that is very hot blue stars
  • In 1970, she became the director of the new optical astronomy laboratory at the NASA Goddard Space Flight Center in Greenbelt, Maryland and worked for NASA in both the United States and Paris until 1977
  • Her career included work at the Copenhagen Observatory, Dominion Astrophysical Observatory, Harvard, Princeton and University of Utrecht (Netherlands)
  • She was awarded honorary degrees from York University in 1969 and UBC in 1992

Anne is an amazing example for women of all ages as she rose to overcome many of the female stereotypes in her industry and of the times.

Remembering William (Bill) Robinson

Bill Robinson

William (Bill) Grigor Robinson
August 23, 1928 – October 19, 2019

William Grigor Robinson P.Eng., CLS, and BCLS, age 91, of Vancouver, passed away peacefully at home in his sleep on Saturday, October 19, 2019. Bill, along with his twin sister Helen were born in Victoria to Henry and Helen Robinson on August 23, 1928.

Bill is survived by his sons Bill (Robyn), Patrick (Leigh), and Warren (Kerry); the grandchildren: Katita, Jacqueline, Sterling, Alexander, Matthew, Hunter, Isabelle, Keira, and Jamie; as well as his great-grandson Harvey. He also leaves behind numerous loving relatives, friends, and business colleagues. In 1954, Bill met and married the love of his life Barnie McAllister.

Bill attended Oak Bay High School and UBC, eventually graduating — after becoming a Bridge Champion — with his degree in Civil Engineering. He worked on many known landmarks such as the Patullo Bridge and the Deas Island Tunnel, but his love of the great outdoors pulled him to follow his real passion, Land Surveying. Bill started working for Underhill & Underhill in 1950. Over his career he cut a swath across Western Canada laying out the boundaries of Provinces and Territories, the Trans Canada Highway, as well as private lands and mine sites. Pretty much anywhere one lays a foot in this province, Bill was there first. He particularly enjoyed his business colleague Tim Koepke with whom he would stomp around the wilderness chiding each other about anything and everything. It started as mentor/mentee and evolved to professional equals and lifelong friends.

Bill worked tirelessly for his family, his business, and the professional associations in which he took pride in being a member. He was a gentleman through and through who always maintained his dignity — a wonderful, very special man.
