Project Experience: Design Engineering

 

The consultant team at Arch Engineers have been very busy delivering high-quality design engineering, drafting and consulting services to a variety of industries – civil, residential, construction, mining, energy and oil & gas.

When quality is a given, speed is our differentiator!

DPI THRUSTER EXCAVATION SUPPORT SHORING (URGENT)

With severe delay penalties on the line for contractors, Arch responded to this failed shoring box system with urgency and pragmatism.

Pipeline expansion through Rocky Mountains  |  British Columbia

Initial designs of the shoring were appropriate for the geotech and bore-hole data analysis, but unusual cobbles and boulders resulted in severe difficulty for the contractor while installing the sheets.

Analysis of the failed shoring caused significant panic and concern from the Owner and General Contractor – relieved by urgent and pragmatic ideas.

Final design was flexible, easy to install, and accommodating of the known unknowns.

CRANE ASSISTED BRIDGE LAUNCH

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.

CRANE ASSISTED BRIDGE DE-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.

CAST-IN-PLACE WINGWALLS AND ABUTMENT

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.

 

STEEL SUBSTRUCTURE FOR RECREATIONAL / PEDESTRIAN BRIDGE

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.

 

TRUSS BRIDGE PIPE RACK

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.

STRUCTURAL DESIGN FOR PIPELINE INSTALLATION

Structural engineering and design for crane-assisted pipeline installation - Arch Engineers

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.

URGENT DRAFTING SUPPORT FOR ENERGY INFRASTRUCTURE

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.

CREATIVE STEEL CONNECTIONS

Creative Steel Connections Design Engineering - Arch Engineers

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 CONCRETE DESIGN AND DRAFTING

Precast concrete design, intended use and handling - Arch Engineers

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.

Project Experience: Program Management

 

Owners risk capex projects hoping for confidence and certainty from their program managers. This provides them with opportunities to press for better schedules and optimized budgets from their General Contractors.

Arch provides Owners with that confidence and certainty.

PROGRAM MANAGER - Las Vegas Venue Construction

Program Management - Construction - arch engineersEntertainment Venue Construction Project – Las Vegas

Technical specialists currently provide a valuable role in QAQC and validation of materials and manpower, both on and off-site. This being a T&M Contract, the scope burden for Arch Engineers is the monitoring and inspection of almost every aspect of the project; from dealing with engineers and designers performing conflict and clash detection, to interfacing with general contractors and subcontractors resolving schedule and operational conflicts – all the while supporting the Owner by reviewing and validating pay-applications.

 Agility in operations and ability to scale up and down without interruption of quality service has positively impacted the schedule, cost-controls, and certainty for the Owner.
