Highway Engineering

In Quebec and elsewhere in the world, CIMA+ has built hundreds of kilometers of highway and freeway. Our highway engineering experts work with owners and their staff to design transportation infrastructure properly suited to their specified requirements, within allocated budgets and according to agreed-upon schedules.

 

The team members carefully plan the various phases of work so that accessibility to services and residential areas is maintained during construction.

 

The following is an overview of the services we offer: 

  • planning (opportunity and pre-project studies, including environmental assessment studies)
  • design (plans, preliminary and final specifications)
    • highway design (plan and profile)
    • design of simple and complex interchanges
    • design of at-grade intersections and roundabouts
  • highway drainage
  • development of traffic control and management plans for the various stages of construction
  • cost estimates for highway projects
  • project supervision

On the subject of project management, we also offer guidance services to transportation authorities, particularly with regard to public-private partnership (PPP) projects. For example, the Ministère des Transports du Québec (MTQ, Department of Transportation in the Province of Quebec) is one of our major clients for this type of service, as are many municipalities across Quebec.

 

As regards highway construction, the real challenge consists of meeting clients' expectations in terms of sustainable development, road safety and traffic circulation. To achieve this, we focus on: 

  • proper traffic management
  • proper relocation of utilities
  • obtaining required environmental approvals and properly integrating mitigation measures in our design
  • solving drainage issues for long-term structural lifespan
  • compliance with the clients' standards and guidelines

On the technical level, roadway geometry must ensure the free flow of traffic, and user safety. Finally, it is important that project costs be estimated correctly in order to allow owners to prepare their budgets.

 

 

Complementary expertise in railway transportation

 

Over the last few years our highway engineering department has developed expertise in the field of railway transportation.

 

CIMA+ became involved in this field in order to meet needs identified during performance of highway interchange design projects sited in close proximity to railways, requiring displacement of the railbed.

 

This new expertise has allowed us to work on significant projects including the construction of 44 km of railway in the Wabush region of Labrador.

 

 

Projects completed on behalf of the Ministère des Transports du Québec

PUBLIC-PRIVATE PARTNERSHIP (PPP) GUIDANCE

Autoroute 25

In the context of choosing a PPP concession holder for the completion of a segment of the A-25 in Montreal and Laval over 7.2 km, including the construction of a 1.2 km bridge over Rivière des Prairies, CIMA+ provided assistance to the MTQ to define the design from a technical standpoint.

 

During this project, CIMA+ completed or participated in the completion of the following tasks:

 

  • technical evaluation of scenarios and complementary studies
  • development of the reference project
  • services associated with engineering (design, cost estimates)
  • development of design, construction and maintenance requirements
  • development of technical compliance grids to be used by the selection committees to assess bids
  • participation with legal and financial specialists, to prepare the technical specifications of the PPP Agreement
  • at the beginning of, and during the process, providing information to the candidates regarding the meaning of technical requirements, and answering their questions
  • assistance for installation of an electronic documentation room
  • application of the partnership agreement during infrastructure construction.

CONSTRUCTION OF THE CONCORDE INTERCHANGE

Autoroute 15

To facilitate movement along Autoroute 15 in Laval within the area bounded by Cartier Blvd and Du Souvenir Blvd, one interchange and two collector roads were built to improve traffic flow between the freeway and the municipal network.

 

CIMA+ completed the pre-project study, plans and specifications and provided site supervision.

 

FULL RECONSTRUCTION

Dorval Interchange (Autoroutes 20 and 520)

For CIMA+, the first stage of the project consisted of producing the opportunity study and the environmental impact study associated with the improvement of overland access to the airport.

 

Next, CIMA+ completed the preliminary and final pre-project studies, which allowed us to fine-tune the chosen solution, to establish project costs with greater precision and to define construction work phases such that the impact on neighbours and highway users was kept to the minimum. Maintaining permanent access to the airport and the train station represented a significant challenge.

 

CIMA+ then prepared the plans and specifications and participated in coordinating the work with the various stakeholders involved, specifically Aéroports de Montreal (ADM is responsible for the management, operation and development of Montréal-Trudeau and Montréal-Mirabel international airports.), CN and CP, the City of Dorval, Hydro-Québec, Bell Canada and Vidéotron.

 

CIMA+ was also asked to provide construction site supervision.

PAVEMENT REHABILITATION

Autoroute 13

The project consisted of the rehabilitation of 3 km of pavement between Autoroute 640 and the Rivière-des-Mille-Iles, with construction of a new concrete slab.

 

The works included earthmoving, roadway foundations, placement of a new cement concrete slab with short non-reinforced slabs and prefabricated slabs. Access ramps were rebuilt and a bituminous surface was applied.

 

CIMA+ completed the design (plans and specifications) and provided site supervision.

RECONSTRUCTION

Turcot Complex

CIMA+ conducted the feasibility study, the solutions study and the preliminary pre-project study for the reconstruction of the Turcot Complex. The design team is currently working on the final pre-project studies and preparation of the plans and specifications required for the various phases of construction.

 

The work was planned in such a way as to minimize the impact on the 280,000 users of this large traffic interchange within Montreal's road network.

 

To accomplish this, CIMA+ developed a solution that allowed the new infrastructure to be built beneath or parallel to the existing one, in such a way that highway connections will remain operational and accessible at all times.

PAVEMENT CONSTRUCTION

Autoroute 50

For CIMA+, this project consisted of the preparation of plans and specifications and monitoring of the work involved in the construction of an 11 km pavement segment of the new Autoroute 50, between Thurso and Plaisance.

 

This new access is located in an area with low-bearing capacity clay soils, requiring the application of special features such as lightweight fill, vertical drains and discharge wells.

CONSTRUCTION OF AN ARTERIAL ROAD

Des allumettières Boulevard

This project involved the construction of a four-lane boulevard, 3 km in length, which was required to cross a densely populated urban area and Gatineau Park.

 

This project highlighted two innovations in Quebec, namely the complete traffic operations management of the urban intersections by roundabouts, and construction on an abandoned landfill in order to upgrade the site and reduce the impact on the natural environment.

 

CIMA+'s role consisted of preparing the plans and specifications and monitoring the work within the park area.

 

This project, which was completed in partnership with other firms, was awarded a Léonard at the Grand Prix du Génie-conseil québécois (Quebec Consulting Engineering Award) in 2009.

MAJOR RECONSTRUCTION

Autoroute 85

Rivière-du-Loup / Saint-Antonin Area

 

This project involved the reconstruction of a section of Highway 185 to create a freeway over a distance of 6.35 km, the construction of secondary pavements (ramps, service road, etc.) as well as the construction and development of three overpasses.

 

The project consisted of various tasks such as earthmoving, rebuilding the median strip, lightweight fill, drainage, roadway structure, paving, retaining wall, lighting, overhead signage, water systems, run off and wastewater drainage, and landscaping.

 

CIMA+ performed the final pre-project study and design, and monitored the work.

 

Cabano / Saint-Louis-du-Ha! Ha! Area

 

For CIMA+, this project consisted of conducting the final pre-project study, preparing the plans and specifications, and providing construction site supervision for the reconstruction of Highway 185 to make it a four-lane divided freeway over a distance of 6.8 km between Cabano and Saint-Louis-du-Ha! Ha!, located in the Témiscouata MRC (An MRC is the regional assembly of several municipalities within the same territory which provides services to its constituting members.).

 

The reconstruction work included the design of roadways, service roads, structures, connections to existing roads and streets, highway lighting, retaining devices, overhead signage and roadside signage.
