Beaverbrook Art Gallery Pavilion Expansion

The main addition is a 1,300 m², three storey structure featuring a contemporary design and housing new gallery spaces along with a large outdoor terrace. The building is steel framed with seismic forces resisted by steel cross bracing. The steel framing accommodated the contemporary design in which the upper floors overhang the lower level. The project is located on a flood plain and required an elaborate system of steel sheeting piling and reinforced concrete work to prevent flood waters from entering the building. Due to poor soil conditions, a piled foundation was required.

The project also included significant renovations to the existing gallery space to accommodate the new Harriet Irving Gallery.

Campbellton Memorial Civic Centre

This new complex consisted of a new 15,000± m² multi-purpose facility containing 2 ice surfaces with a seating capacity of 2400, a 25 m, 8 lane Olympic swimming pool, racquet ball and squash ball courts, community rooms and a convention center. The building was constructed using structural steel framing with compositely designed floors used for economy, fire resistance and vibration resistance. The building featured several unique architectural designs requiring innovative structural design. As structural consultants, Eastern Designers were able to meet the intent of the Architect’s design by utilizing unique and sophisticated structural analysis and design while still keeping the structural costs $0.5±M under budget.

Food Processing Plants(Cavendish Farms Expansion No. 2)

This project consists of a major new 279.5 m (17,000± m²) long food processing plant. This large industrial project (incorporating a large office section) was framed with structural steel framing using gerber girder construction and steel roof beams to create large column free areas, economize application of required protective coatings and permitted fast track design and construction of the structure prior to the final selection of roof top equipment. Seismic forces were resisted by cross bracing. Included in the design were extensive mezzanines, equipment platforms, catwalks, concrete pits and reservoirs, extensive dock levelers and overhead doors.

Little Tracadie River Bridge

This 12 span continuous, 2 lane, 342.5 m precast girder bridge crosses the Little Tracadie River estuary and was constructed in 2001.

Geotechnical considerations required the removal of unsuitable material and the construction of a new approach fill at the north end of the structure. The material to be excavated was below the fluctuating tidal water level. Shot rock was used to raise the approach fill above the tidal water level to the underside of the north abutment. The excavation of the unsuitable material was completed in a silt boom enclosure to conform with the environmental control requirements for the site.

The bridge superstructure consists of a concrete deck supported by NBDOT Type 1 precast, prestressed concrete reinforced girders. The superstructure was supported on economical pipe pile bents in an aggressive marine environment. At pier 1 and 11, H-pile leads were required to ensure anchorage into the bedrock. A cathodic protection system was developed to extend the life of the steel pipe piles considering the harsh marine environment.

Bathurst Village Bridge

This 8 span continuous, 4 lane, 226 m long precast concrete girder bridge crosses Bathurst Harbour and was constructed in 1997 to replace an existing bridge. The 28± m span configurations avoided interference with the existing piers. The bridge girders were constructed using precast prestressed concrete NBDOT Type 1 beams.

The prestressed concrete girder structure was supported on economical pipe piled bents in an aggressive marine environment. A cathodic protection system was developed to extend the life of the steel pipe piles considering the harsh marine environment.

In order to reduce the substructure costs, pile load testing was performed early in the design.

The bridge has a 2 m wide pedestrian sidewalk on the west side with a custom aluminum pedestrian railing and light standards.

Aroostook River Bridge

This $18.5±M, 5 span continuous, 4 lane, 365 m long steel girder bridge was part of the Longs Creek – Grand Falls Trans Canada Highway project constructed by Brunway Group in 2005 – 07. The 4 lane structure was constructed with 80 m spans over the water along with 65 m and 60 m back spans over land.

The Aroostook River at the crossing site is a wide, shallow, boulder strewn, rapidly flowing stream, bounded by high steeply sloping wooded river banks. By using long span steel plate girders and combining the east bound and west bound lanes on a common foundation, only one pier was required to be constructed within the environmentally sensitive water course.

The bridge girders were constructed using unpainted, weathering steel protected from spray and bridge deck run off by a waterproof membrane and concrete deck slab cantilevering well beyond the bridge’s steel spandrel girders.

The use of expansion joints was minimized with only two finger plate expansion joints located at the bridge abutments. Pot bearing assemblies were used to support the bridge superstructure.

Substantial quantities of large riprap and heavy geotechnical fabric were used to prevent erosion in the vicinity of pier foundations. Above the maximum river flood level, geotextile fabric and rock fill slope protection were used to control erosion of bridge approach fills.
