World Demolition Awards 2023 - Civils Demolition shortlist

Delsan-AIM, Canada
PROJECT: Champlain Bridge
CLIENT: Jacques Cartier and Champlain Bridges Incorporated

The Champlain Bridge spans the St Lawrence River in Montreal and is 3,441 m (11,289 ft) long from abutment to abutment.

After a replacement bridge was opened in 2019, Jacques Cartier and Champlain Bridges Incorporated (JCCBI), contracted the “Nouvel Horizon Saint-Laurent (NHSL)” joint venture - for which Delsan-AIM Environmental Services was the main partner - to undertake the planning, engineering, and deconstruction of the original Champlain Bridge.

A three-and-a-half-year project, the most recent phase of the project saw Delsan-AIM demolish Section 7 of the bridge. The section measured over 0.5 km long and comprised spans of 53.7 m long and 24.1 m wide, support by concrete piers ranging from 10 m to 20 m in height.

Despe, Italy
PROJECT: SPIN Torviscosa
CLIENT: SPIN spa

Despe was engaged to carry out the deconstruction and dismantling of an abandoned industrial complex in Italy. The project comprised the removal of reinforced concrete warehouses that measured up to 40 m high, and which were previously used for the production of raw materials for the chemical and pharmaceutical industries.

Situated in an industrial centre, the site was flanked by roads and other active industrial businesses, requiring Despe to perform targeted dismantling using a zero impact approach that adhered to Seveso regulations.

Grupo Mitre, Argentina
PROJECT: Alberdi Ceramics Demolition
CLIENT: Ceramica Alberdi

Grupo Mitre completed the demolition of 10 separate buildings located at Ceramica Alberdi’s production plant in the province of Buenos Aires.

The works were carried out without hindering the function and operation of the factory facility, and involved the demolition of structures with cement sheet roofing. The roofing contained significant levels of asbestos, which Grupo Mitre removed in a controlled and safe manner with the help of a specialist team.

Max Wild, Germany
PROJECT: “Via6West” Neckartal Crossing
CLINET: BiGe Bunte - HochTief

Max Wild undertook the demolition of the 1.33 km long Neckartal Crossing, which carries the A6 motorway over Germany’s Neckar River and its adjacent flood plains, as well as other roads and railway lines in Germany.

Described as an extraordinarily complex project, the entire crossing consisted of four statically different substructures, each of which required its own dismantling procedure with specific challenges. In total, around 85,000 t of concrete was demolished and processed, and 6,500 t of steel was dismantled and recycled.

QM Environmental, Canada
PROJECT Stack Infrastructure
CLIENT Ellis Don Corporation

QM Environmental carried out interior and exterior demolition works at a 90,000 sq ft pharmaceutical manufacturing building in Toronto, Canada. The contractor removed the structure’s concrete panel roof to expose the existing structural steel framing that would be modified to accept new roofing.

The entirety of the plant’s second storey was also demolished. QM sawcut around the columns of the main building slab to minimize vibration and to tie-in new structural slab that was due to be installed. Working in a confined basement, the contractor also removed 7,000 linear feet of piping infrastructure.
