HIGHWAY BRIDGES AND GRADE SEPARATION STRUCTURES
|
|
Scouten & Associates Engineering Ltd. provides
conceptual, preliminary and detailed design of
highway bridges and grade separation structures
in accordance with CAN/CSA-S6 Design of Highway
Bridges or other governing design codes. Design
services are available for all substructure and
superstructure components, and ancillary features
such as approach roadworks, guardrailing, sidewalks,
etc.
|
 |
|
Scouten & Associates Engineering Ltd. has
direct experience in the design and construction
of precast concrete structures, with both conventional
and pre-stressed reinforcement systems. We designed
a grade separation structure for the BC Ministry
of Transportation that utilized precast, post-tensioned
'tub girder' segments, acting compositely with
a high strength, cast-in-place concrete deck.
Other structural systems for bridges and grade
separation structures, including trapezoidal
steel box girder and conventional plate girder
arrangements, have been designed by Scouten & Associates
Engineering Ltd. In all cases, the design drawings
are produced to the highest level of standard
specified by the relevant approval agencies.

BRIDGE ABUTMENT AND SUBSTRUCTURE DESIGN
|
|
All requirements of the regulating authorities
(Department of Fisheries and Oceans, Land and
Water British Columbia Inc., the Navigable Waters
Protection Act etc.) are clearly identified at
the design stage, and incorporated into the construction
specifications. Particular attention is paid
to erosion protection and sediment control in
fish bearing streams and rivers.
|
 |
|
Bridge abutment designs are always site specific
and are finalized only after watershed hydrology
is complete and an accurate site plan has been
developed.
Bridge abutment solutions include driven pipe
piles, precast concrete spread footings, galvanized
binwall systems and cast-in-place concrete alternatives.
Scouten & Associates Engineering Ltd. works
closely with road design, survey, river hydrology
and geotechnical sub-consultants to provide complete
and accurate foundation system design.

RESOURCE ROAD BRIDGE DESIGN, TENDERING AND
CONSTRUCTION SUPERVISION
|
|
Scouten & Associates Engineering Ltd. offers
complete design, drafting, tender documents and
construction management services for resource
road bridges throughout British Columbia and
northwestern Alberta.
All bridge designs are in accordance with CAN/CSA-S6-00
Design of Highway Bridges, modified for the specific
requirements of the resource sector client. Design
loads often exceed 100 tons gross vehicular weight
and spans vary from 15 metres to over 100 metres.
|
 |
|
Resource road bridges are often constructed
in remote areas, under conditions of extreme
topography and adverse climatic conditions. The
design of bridges for the resource sector must
be sensitive to the short construction seasons
available in the north and restrictive backcountry
environmental regulations.
Superstructure configurations include simple
and continuous spans, supported by a variety
of foundation options. Construction materials
include structural steel, precast, pre-stressed
concrete, cast-in-place concrete and structural
timber.
Scouten & Associates Engineering Ltd. provides
complete tender and construction period services,
including contract preparation and administration,
field inspection and final certification.
