PENNASK CREEK - KELOWNA, BC
Owner: BC MOTI
Consultant: Associated Engineering
Contractor: PW Trenchless
Location: Pennask Tributary Creek, 50km outside
of Kelowna, BC along Highway 97C
Existing Culvert:
2440mm Span x 1739mm Rise Galvanized Multi-
Plate pipe arch
Rehabilitated Culvert:
• 2046 mm x 1538 mm rise x 97m length
• 4.0mm crown plates x 6mm bottom plates
• Strata-CAT® polymer-coated

49
Challenges & Constraints
• Restore structural capacity of the culvert
• Approximately 30m surcharge
• 75+ year service life
• Timeline – difficult winter conditions
• Major highway
• Max. water velocity  3.0 m/sec with sand
and gravel bedloads
• Acidic drain rock
• Water inside conduit:
• Leachate from acidic surcharge
around conduit/grout

DICK BOOTH CROSSING - HWY 4 PORT HARDY,
BC
Owner: BC MOTI & MFLNRO
Consultants:
• Onsite Engineering (Engineers of Record)
• Terratech Consulting (GRS)
• Pacificus Biological Services Ltd.
(Environmental Monitoring)
• Levelton Consultants Ltd (Quality Control)
Contractors:
• PW Trenchless
• Newcastle Structures (SPCPS and Concrete)
• West Bridge Corp. (Removal of Acrow Bridge)
• LC Stoneworks Ltd. (Installation Lock + Load)
Project Description:
• Access to the community of Holberg, BC was cut during a rain event in which 300mm
of rain fell in a 24 hour period and washed away a 2.0m CSP
• BC MoTI quickly installed a temporary single lane bridge to re-open the road and
maintain essential services.

52
BC
Issues:
• Water infiltration through
the embankment was a
concern
• Bedrock was relatively
close to the surface
• Implied subsurface erosion
was likely, due to piping
(percolation of water along
the bedrock surface).
Resolution:
• Impervious cast-in-place concrete cut-off wall was anchored into the bedrock.
• Cut-off wall ensured the water takes the path of least resistance – through the Multi-
Plate structure

53
BC
Multi-Plate used:
• Multi Plate® c/w Strata-Cat® polymer
coating
• Corrugation = 152mm x 51mm
• 4.920m dia x 4.0mm width x 25.28m length
Project Materials Supplied by Armtec
• Multi Plate® c/w Strata-Cat® polymer
coating
• Lock + Load retaining wall
• GRS Basket
• Geotextile
• W-Beam Guardrail

54
PARKDALE CREEK – LANGFORD, BC
Project description:
• Parkdale Creek is an environmentally sensitive fish-bearing stream that meanders
through the heart of the Westhills subdivision.
• In order to join the two halves of the neighborhood it required a structure that would
span the creek in an aesthetic and environmentally friendly way.

55
Structure description:
• Bridge-Plate® arch structure
• 12.0m span x 5.948m rise x 36.0m long
• Entire assembly only required eight
days.
• Assembly crew preassembled
complete rings of the arch in a
staging area while the skew collar &
footing designs were completed.

56
• This project incorporated a green wall system that used Mirafi 5XT uniaxial geogrid
reinforcement.

57
THOMPSON’S CREEK - HOUSTON BC
Existing structure:
• 2 x 900mm dia. CSP
• 1 x 600mm dia. CSP
• Constricting a 4.2m creek channel
Replacement structure:
• 7.0m span x 24m long open bottom
arch.

58
THOMPSON’S CREEK - HOUSTON BC
Project success:
• Project has restored fish access to over five kilometers of high value spawning and
rearing habitat in the Thompson Creek mainstream
• A further estimated two kilometers of habitat in four smaller tributary streams located
upstream of the Yellowhead Highway 16 also have restored fish access.

59
KLUSKUS ROAD - VANDERHOOF, BC
• Road re-alignment project. Structure needed to be outside the wetted perimeter of the
creek as this is a fish bearing stream.

60
KLUSKUS ROAD - VANDERHOOF, BC
Solution:
• 15 metre span, 7.4m rise Bridge-Plate®
• Single Radius Arch
• 5mm thick throughout
• Concrete footing/headwall – Designed
by McElhanney
• Bin-wall – Design A,B,C

62
Solution Specifications:
• The Bridge-Plate two-radius arch design parameters were:
Span = 15.0 m, Rise = 6.7 m, Length = 58.9 m
• 8.0 mm thick corrugated plate
• Minimum Cover = 3.0 m
• Maximum Cover = 9.1 m

63
Solution Characteristics:
• Mine haul truck overpass
• 1,400,000-lb. loaded CAT 797
• Structurally efficient design

64
BENEFITS OF CORRUGATED STRUCTURAL STEEL
PLATE PRODUCTS
• Customized shapes to fit the application
• Cost efficient
• Low life cycle cost
• Economically shipped to remote
locations
• Ease of installation w/o large cranes
• Less design & construction time is required
• Can be designed for a wide range of loading
conditions
a) Deep bury
b) Heavy Live Loads (haul trucks, track
vehicles)
c) Typically have reserve capacity for
overload conditions
d) Seismic forces

65
• Eliminates bridge decks & icy
deck problems
• Eliminates maintenance of
bridge approaches
• Permits the use of a constant
roadway section in the vicinity of
the structure
• Roadway extension can be
easily accommodated
• Cost Effective
