PENNASK CULVERT REHABILITATION

7


PROJECT BACKGROUND

Owner: BC MOTI

Consultant: Associated Engineering

Contractor: PW Trenchless

Location: Pennask Tributary Creek, 50km outside of Kelowna, BC along Highway 97C

Existing Culvert Condition: 2440mm Span x 1739mm Rise Galvanized Multi-Plate


8


PROJECT BACKGROUND

Project Requirements• Restore structural capacity of the culvert• 75+ year service life


9


PROJECT BACKGROUND

Challenges & Project Conditions

• Approximately 30ft. surcharge

• Timeline – difficult winter conditions

• Max. water velocity 3.0 m/sec with sand and gravel bedloads

• Acidic drain rock• Water inside conduit: 4 ≤ pH ≤ 9• Leachate from acidic surcharge

(3 ≤ pH ≤ 9) around conduit/grout

YVR DETENTION SYSTEM

19


PROJECT BACKGROUND

Owner: Vancouver Airport Authority

Consultant: Urban Systems Ltd.

Contractor: Hexcel Construction Ltd.

Location: Vancouver International Airport


20


PROJECT BACKGROUND

Project Requirements• Design for 200m3 storage volume• Minimum 75 year service life• Minimal infiltration/exfiltration


21


PROJECT BACKGROUND

Challenges & Constraints

Geometric• Needed to fit the system in a trench

width of 4.5m• Maximum depth of the system was

1.9m due to a high water table• Total available footprint was 60m x

4.8m

Time-dependent• Needed the system onsite within 4

weeks of order placement


22




Solution

2 x 55m runs of 1400mm Hel-Cor CSP• Trenchcoat Polymer Laminated• H-500 Hugger-Band Couplers

24


STORMWATER DETENTION


CSP Detention Systems

• Hel-Cor & Ultra-Flo CSP• Pre-fabricated bulkheads & fittings

Hel-Cor CSP Detention System Bulkheads & Risers

25




CSP Detention Systems

• Aluminized & Trenchcoat Polymer-Laminated for superior durability• Smooth interior of Ultra-Flo simplifies maintenance

Polymer-Laminated CSP Detention Tanks Ultra-Flo Tank w/ Bulkheads, Risers, & Flow-Restricting Outlet Stub

26




Design Considerations for CSP Detention Systems

1. Required storage volume

2. Geometry / footprint

3. Required lifespan

4. Pre-treatment

5. Infiltration / exfiltration

6. Outflow / release structure

7. Maintenance

27




Advantages of CSP Detention

• Customizable shape, size, layout• Cost effective• Familiar installation methods• Easy maintenance• Can perforate to create a retention / infiltration system

28




HDPE Detention Systems

• Steel-reinforced HDPE for superior durability• Up to 3000mm dia. for storage of large volumes• Pre-fabricated bulkheads & fittings• Watertight system

DuroMaxx Detention System DuroMaxx Detention Tank w/ Bulkhead & Access Riser

NOISY RIVER BRIDGE

30


NOISY RIVER BRIDGE

• Owner: County of Dufferin• Consultant: R. J. Burnside & Associates• Project: Replacing Cast in Place Box Culvert

31


NOISY RIVER BRIDGE

Major Site Constraints:• Couldn’t close road • Couldn’t enter or contaminate stream• Contract limits = County Right of Way

32


NOISY RIVER BRIDGE

Stage 1 - Construction

Temporary Geotextile Wall

33


Temporary Wall Construction

1. Pull geotextile tight, keep tension applied until backfill is placed.

Compacted fill

Native Soil

Depression for geotextile wrap

Removable form

2. Place backfill in specified lifts and compact to 95% Standard Proctor.

34


Temporary Wall Construction

1. Place second removable form by repeating step 2.

Native Soil

2. Place second layer of geotextile and reinforced fill by repeating steps 3 through 4.

3. After completion of second lift, jump the first form.
