Manufacturing plant for wind turbine blades

LM Glasfiber Canada, Gaspé

CIMA+ was assigned the task of producing the construction documents for a 9,700 m² plant, 8,200 of which would be used for the manufacture of wind turbine blades. This project was subjected to very tight deadlines.

These wind turbine blades are fabricated using a special lamination process combining fibreglass and other composite materials. This process required special air collection and supply systems.

Fire protection for this process is also quite specific.

Rebuilding the roof of a train hangar

AbitibiBowater, Gatineau

The train hangar at the AbitibiBowater plant in Gatineau forms part of the building heritage of the city. It was built in the 1920s, according to the standards of that time.

Today, the hangar serves a variety of uses, in addition to its original vocation as a train hangar. It is used in particular as a garage, chemical products depot, battery charging room and electrical room.

CIMA+ was asked to evaluate existing conditions, prepare drawings and plans and to supervise the rebuilding work. The structure was designed to comply with current standards. In addition, the work was completed without any budget over-runs, without interrupting operations at the plant and fully within the established timeframe.

The project posed several challenges, with the greatest being the requirement that the impact on daily work of the plant be kept to a minimum. Furthermore, the building work had to be respectful of the architecture of the building heritage represented.

Structural rehabilitation of chests

AbitibiBowater, Gatineau

For the purposes of this project, CIMA+ conducted an in-depth examination of the chests to identify the causes of the premature deterioration of the walls and ceilings. Once the deficiencies were identified, we proceeded with structural analyses and prepared drawings and plans to reinforce the chests.

The technical solutions chosen consisted of repairing the concrete walls, protecting the reinforcing steel with a cathodic protection system and insulating the exterior walls to reduce the thermal gradient in the concrete mass.

About 20% of the walls were repaired in 2001 and the remaining portion of the rehabilitation work was completed in 2002.

Structure for gas collection equipment

Smurfit-Stone, Portage-du-Fort

The CIMA+ team demonstrated their capacity for innovation in this project, requiring the installation of a system for the capture and incineration of waste collected at the vents of the storage facility, separating the solid ash from gas.

Initially the project would have required the expensive construction of a new building. To reduce costs, CIMA+ successfully adapted and reinforced the existing structure, allowing it to support the significant loads applied by the new equipment.

Our expertise allowed us to develop a design for equipment access that was suited to the client's needs. We also provided coordination and supervision of all structural work designed to support the equipment and we developed the operational logistics for the installation and layout.
