TM ROCO

What TM ROCO does

TM ROCO is a temporary consortium (tijdelijke maatschap) of ten Belgian construction companies — BESIX, BESIX Infra, DEME Infra, Dredging International, Jan De Nul, Cordeel, Denys, Franki Construct, Willemen Infra, Van Laere and, as expanded, BAM Contractors — established in 2017 to execute Perceel 3B (the right-bank works) of the Oosterweelverbinding project in Antwerp. The consortium's single client is Lantis (Beheersmaatschappij Antwerpen Mobiel NV), the Flemish government-controlled contracting authority for what is described as the largest infrastructure and liveability project in Belgium and Europe. The scope covers building the Kanaalzonetunnels (Canal Zone tunnels), demolishing the iconic Merksem Viaduct and constructing a depressed ring road across seven sub-project areas (KZT, VRK, R1N, R1O, OKA, TR1, SK), with approximately 792 personnel deployed across 26 active sites over a 10-year execution period.

The consortium's technology backbone is full-lifecycle Building Information Modelling (BIM) to ISO 19650 standards, combined with Systems Engineering and digital project platforms (Relatics, Aconex, SharePoint, Oracle Primavera P6) for information, requirement and asset management. TM ROCO is operating Belgium's first NEC4 (New Engineering Contract) form, an integrated and collaborative contract structure with Lantis that replaces traditional adversarial procurement. The consortium also deploys on-site concrete and bentonite plants, waterway transport logistics, circular-construction recovery systems, and real-time environmental monitoring of water and energy consumption.

TM ROCO generates revenue through a single prime contract with Lantis for Perceel 3B, executed on a multi-year, fixed-price and reimbursable basis under NEC4 terms. Pricing is project-specific and not publicly disclosed; the commercial model is enterprise/government field sales via competitive tender. The consortium markets itself primarily for employer branding and talent attraction through LinkedIn and Instagram, while earned media coverage from one of Europe's highest-profile infrastructure projects provides reputational reach. Beyond Perceel 3B, the temporary consortium has no disclosed follow-on projects, additional customers, or geographic diversification beyond Flanders.
