Bridge launch | Northern Saskatchewan

Arch responded to an urgent request for engineering assistance on a bridge launch project in Northern Saskatchewan.

After review of the bridge design details, Arch designed a “push beam” for the excavator and a simple system of hillman rollers and cribbing to slide 4-girder lines across the creek in winter conditions.

The crane was available for assisting the launch, which removed the need for counterweight on the bridge – allowing for a faster launch.

Bridge de-launch | Remote British Columbia

As part of a BC pipeline project, these decommissioned bridges needed to be removed – Arch was selected to design the removal methodology.

With the crane and excavators already in the area, this simple counterweighted de-launch was designed. The crane assists two excavators to pull the bridge across the abutment and onto the excavated embankment.

Ingenious solutions were provided to optimize the sliding of the bottom flanges on the retained bearing points.

Basing a design on a similar project, Arch included value engineering (lessons learned) from other projects to deliver this engineering formwork and drafting solution to the general contractor in less than 4 days.

Design requirements included using the formwork specs provided by the general contractor, and solving for the issues specific to this site’s challenges.

Recreational bridge substructure design & details – Alberta

As part of a complicated Joint Venture between a Designer, Fabricator, and General Contractor, Arch supplied engineering and drafting services to this complicated project.

This structure required being designed to be connected on top of an existing 100-year old decommissioned railway bridge.

Adequate assessment of the existing structure included metallurgical coupon testing, and high-definition drone survey, before designing a structure to meet AT and CSA codes. Welding methodologies and constructability were key to the success of the project.

Very tight timelines were met in order to achieve the manufacturing and fabrication schedule, with several just-in-time drawing packages made available to the workshops involved.

Gas Pipeline Crossing Truss Bridge – British Columbia

This Design-Build project included construction methodology, crane lift planning, engineered lift plans, truss bridge design, bearing designs, pipe connections, bearing design, as well as interfacing with the fabrication shop for delivery of native .dxf shop drawing files.

Working closely with the owner regarding two uncertified piers used for previous crossings, the new design required significant upgrades to the two main abutments, elevations and sag support for the (much) larger diameter pipe being installed.

 The ultimate goal was to make this installation as cheap as possible for the Owner, simple for the fabricator, easy for the construction contractor, and feasible for the pipe installer – managing multiple stakeholders, and satisfying everyone’s needs.

Provided severe right-of-way constraints, a flexible installation methodology was required to leverage the adjustible shoring design (by ARCH) and make the difficult pipe installation as easy as possible.

Pipeline construction drawings  |  Alberta and British Columbia

Major energy infrastructure projects most often operate under severe delay penalties, or speed incentives.  Either way, production velocity is key to the General Contractor’s success or failure on a particular project.

ARCH’s drafting team can deliver high-quality drawings on fast turnarounds.

Bridge Launch Design Needs Creative Connection Design  |  North West Territories

Asked to use an existing launch nose, and create a connection to an existing bridge design for a bridge launch scheduled to start in two weeks.

Requiring an extremely fast turnaround of design, engineering and drafting (general arrangement, shop drawings and construction drawings) with limited materials available.

Precast Reinforced Concrete Design, incl shipping & handling  |  British Columbia

It’s not just the design of the precast shop drwaings for the intended use, it’s also considering how you load, transport and unload the structures.

Fit-for-Purpose includes the handling for transport and installation, not just the intended functional use-case.

Construction Management Services – Northwest Territories

Technical specialist consultants are delivered to projects and project management teams around North America. This project required a Construction Manager with experience building a pioneer winter road to a very remote mining operation in the Northwest Territories.
