PROFESSIONAL BACKGROUND
Alv Dyregrov is a geotechnical engineer with broad based experience in soil mechanics, foundation engineering
and project management. He has been in consulting geotechnical engineering practice in Manitoba since 1960.
Extensive work has been undertaken on stability analyses of river banks for both minor and major projects,
foundation studies for major and minor buildings as well as inspection of foundation and shoring installation, geotechnical
investigations for a variety of municipal engineering projects, geotechnical studies for various bridge projects,
geotechnical input to siting studies and geotechnical monitoring of performance of various structures.
River bank stability analyses projects have included those associated with the St. Boniface Hospital Energy Centre,
Osborne on The Red, Pembina on The Red, a variety of storm sewer outfalls for the City of Winnipeg and those associated
with major and minor bridge projects, such as the Provencher Vehicular and Pedestrian Bridges.
Foundation engineering studies and subsequent inspection of foundation installations have been carried out for the
Portage Place Development, Morden Research Station, Manitoba Sports Federation Building, Health Sciences Dentistry
Building, Misericordia Hospital and Health Sciences Centre major renovations, Concordia Hospital Addition, St. Boniface
Hospital and Health Sciences Centre Parking Structures, MTS Centre and high rise structures such as 200 Graham Avenue,
Woodsworth, Imperial Broadway, Union Centre, Provincial Remand Centre, Law Courts, Inter City Gas, Wawanesa,
the UGG, One Canada Centre, Bank of Montreal, Cargill, Great West Life, Downtown Manitoba Hydro Office Building and
Air Canada Buildings. Work on other major structures includes the Winnipeg Mint, Winnipeg Library, Winnipeg Arena
Expansion, Boeing of Canada, Hudson Bay Company Distribution Centre, McCain's Foods in Portage la Prairie, Winnipeg
Taxation Data Centre, Simplot Potato Processing Facility in Portage la Prairie, Olymel Hog Processing Facility in
Winnipeg, and hangars and maintenance facilities for Air Canada.
Most recently, studies for the new Winnipeg Airport Authority air terminal, parking structure and air and land
side facilities have been completed.
Studies for shopping centres include Kildonan Place, the St. Vital, Portage La Prairie, The Pas, Kildonan Crossing
and many strip malls. Geotechnical studies were also performed for over 30 grain elevators for Manitoba Pool, Pioneer
Grain and the Cargill Inland Grain Terminals at Elm Creek, Manitoba and Rosetown, Saskatchewan. Several terminals at
Thunder Bay, Ontario which have been undergoing lateral movements were also studied.
Geotechnical studies for municipal works include the additions to the West End, North End and South End Water
Pollution Control Centres in the City of Winnipeg, sewage lagoons for The Pas Indian Reserve, Town of Beausejour,
Town of Steinbach, Roseau River Indian Reserve, the McPhillips St. Water Reservoir and Deacon Reservoir Lagoon C, sewer
and water distribution systems at Nelson House and Norway House and the Munro Roland Hart District in Winnipeg.
Geotechnical studies for rail and road transportation including bridge sites were performed for the Chief Peguis Bridge,
Provencher Vehicular and Pedestrian Bridges, the Netnak Bridge near Cross Lake, the University
Transit Corridor, the Charleswood Corridor, the PR240 Overpass at the Trans Canada Highway at Portage La Prairie,
the East Access Overpass of Trans Canada Highway at Brandon, the Kildonan Corridor, the CN spur line serving the
Sylvite Potash Mine, and the CN Double Tracking program in the Assiniboine and Qu'Appelle Valleys.
The geological and geotechnical aspects of the studies to locate a preferred site for a possible Nuclear Generating
Station in Manitoba were a part of a major study which included environmental and other engineering disciplines. Similar
studies were also done for the siting of the proposed Alcoa Aluminum Smelter in Manitoba and the Akjuit Aerospece Centre
in Churchill, Manitoba.
At the time of leaving Hardy Associates, Mr. Dyregrov had been acting as project manager for the design and
construction of the open pit mine for Inco Limited in Thompson. The project included the design of pit slopes some 45
metres in height and the removal and disposal by hydraulic dredging of some 20,000,000 cubic metres of overburden.
Prior to joining Hardy Associates, Mr. Dyregrov was Director of Engineering for the Winnipeg office of
Underwood McLellan and Associates. In addition to the responsibilities for the production of work from this
multidisciplinary group he directed the studies relative to soil mechanics and foundation engineering. Such studies were
associated with bridges, overpasses, dams, buildings, railways, recreational facilities, landslides, municipal utilities and
communication facilities.
Previous experience was with the Canadian Government in Banff, Alberta where he was involved with the design
and construction of highways in the Western National Parks. Earlier work with the St. Lawrence Seaway Authority in
Montreal included the design and construction of dykes, coffer dams, bridge and lock foundations and stability of major
cuts and fills along the Seaway route.
