quebec precast concrete Manufacturers Béton Préfabriqué du Lac (BPDL) and Schokbeton became part of a Montreal milestone when they played a critical role in the development of the province's Autoroute 30, a record-setting infrastructure project designed to ease commuting times for the city's travellers.

Originally conceived in the 1960s as Route 3, the Autoroute 30 initiative was launched to link the towns of Valleyfield and Bécancour with the industrial municipalities located south of the St. Lawrence River. Throughout the decades, however, the project grew in scope, gaining the “Autoroute de l'acier” moniker. It became a highly desired bypass route, alleviating

Les fabrIcants québécoIs de béton préfabriqué Béton Préfabriqué du Lac (BPDL) et Schokbeton font maintenant partie de l’histoire montréal-aise : ils ont tenu un rôle crucial dans le développe-ment de la nouvelle autoroute 30, un projet record d’infrastructures visant à réduire la durée des trajets des automobilistes. D’abord conçue dans les années 1960 sous le nom de route 3, la nouvelle autoroute 30 a pris naissance afin de relier Valleyfield et Bécancour aux municipalités industrielles de la rive sud du Saint-Laurent. Or, au fil des décennies, ce projet a pris de l’ampleur et s’est mérité le surnom « d’autoroute de l’acier ». La NA30 est devenue une voie de contournement

You can’t recall a bridge, or a sewer, or a watermain. That’s why we’ve built a team of more than 30 in-house engineers and technologists. They work with you to examine functionality, durability and lifecycle cost, and to design the products you need to optimize your infrastructure project.

congestion on Montreal's busy highways and consolidating a number of other highways into a more effective transportation network.

As part of this ongoing public-private project (PPP), the Nouvelle Autoroute 30 CJV (NA30 CJV) concession was formed to design, develop, build, finance and maintain a 35-kilometre western section of Autoroute 30 and develop an additional seven-kilometre section – the last two sections of the highway to be completed. The NA30 CJV was made up of Acciona Infrastructures Canada, part of the Spanish-owned Acciona, and Iridium, while key strategic partners included Dragados Canada, Aecon, Verreault Construction, Arup, and S.I.C.E.

NA30 CJV selected precast concrete for 20 of the highway’s major struc-tures, including 18 overpasses and two bridges spanning the St. Lawrence River. One of these, at the Beauharnois Canal, was a 2,550-metre-long structure deemed the longest incrementally launched bridge in North America and the second-longest of its kind in the world. All totalled, the projects saw the installation of over 120,000 square metres (1.3 million square feet) of precast deck slabs and 940 girder beams.

Canadian milestonesNA30 CJV and its partners also succeeded in achieving a few more Canadian and international milestones. For one, the project involved the use of precast girder beams measuring 45 metres in length – the longest beams of their type ever produced in Quebec. This was also the first project in Quebec to have precast deck panels used for the bridge deck. The slabs were produced by BPDL and the girder beams by Schokbeton. The installa-tion of all precast concrete elements was done by Schokbeton.

très prisée qui allège la congestion sur les autoroutes de Montréal et assure le lien avec d’autres autoroutes pour former un réseau routier plus efficace.

Dans le cadre de ce projet en PPP, on a formé la concession Nouvelle Autoroute 30 CJV (NA30 CJV) pour concevoir, développer, bâtir, financer et entretenir le tronçon ouest de 35 km de la 30 et développer un tronçon additionnel de sept kilomètres, soit les deux derniers tron-çons de cette autoroute à compléter. NA30 CJV se compose d’Acciona Infrastructures Canada (une filiale de l’Espagnole Acciona) et d’Iridium. Ses principaux partenaires stratégiques sont Dragados Canada, Aecon, Verreault, Arup et S.I.C.E.

NA30 CJM a choisi le béton préfabriqué pour vingt structures principales, dont dix-huit viaducs et deux ponts au-dessus de la voie maritime du Saint-Laurent. L’un de ces ponts, au canal de Beauharnois est le plus long pont ouvert graduellement en Amérique du Nord et le deuxième plus long au monde dans sa catégorie, avec 2 550 mètres. Dans l’ensemble du projet, on a installé pour plus de 120 000 mètres carrés (1,3 million de pieds carrés) de dalles de tablier en béton préfabriqué et 940 poutres maîtresses.

De nouvelles marques canadiennesNA30 CJV et ses partenaires ont établi quelques marques canadiennes et internationales de plus. Premièrement, le projet a fait appel à des poutres préfabriquées de 45 mètres de long, soit les plus longues du genre produites au Québec. C’est aussi la première fois qu’on utilisait, au Québec, des panneaux de béton préfabriqué pour un tablier de pont. BPDL a fait les dalles et Schokbeton s’est chargé des poutres et de l’installation de tous les éléments en béton préfabriqué.

Precast concrete HigH PerformingBuilding enclosures

Precast concrete has been used successfully to provide durable building enclosures for many decades. Asrequirements for thermal performance, air leakage and rain penetration control increase in modern buildings, precast concrete provides low maintenance, durable long life building enclosures. Precast concrete enclosure walls stand apart from most “rainscreen” walls in several key respects: how they control rain penetration, how they provide air tightness, and their sequence of construction.

tablier des deux principaux ponts, représentait une solution idéale. Les poutres et les dalles se sont installées facilement et rapidement, ce qui a permis de couler la chape peu de temps après. Ainsi, on a pu construire ces ponts en beau-coup moins de temps que ce que permettent les méthodes traditionnelles.

Même si les partenaires de NA30 CJV sont passés à de nouveaux projets, leur contribution à l’autoroute 30 fera partie de la vie des Montréalais pendant longtemps. Grâce à la collaboration de tous, le Québec est maintenant l’hôte de l’un des plus ambitieux projets d’infrastructure au pays, et l’industrie du béton préfabriqué peut s’en enorgueillir sur la scène internationale.

the two main bridges, was an optimal solution to building these two structures. The beams and slabs were erected easily and quickly, allowing for the concrete topping to be poured shortly after the precast concrete bridge deck was installed. As a result, the construction of the bridges was handled much more effi-ciently than would have been the case had traditional methods been followed.

NA30 CJV's partners may have moved on to new endeavours, but their contributions to Montreal's Autoroute 30 will remain part of local residents’ lives for years to come. Thanks to the collaborative efforts of all those involved, Quebec is now home to one of the country's most ambitious infrastructure projects, and the precast concrete industry has laid claim to an internationally recognized success.
