cascoopbouw

Cascoopbouw, often written casco bouw or casco-constructie, is a construction approach used in the Dutch-speaking building sector. It refers to delivering a building in cascoready or cascoshell: the structure, exterior envelope, roof, and essential building services are completed to a point where the property is weatherproof and structurally sound, while interior finishing and often final mechanical, electrical, and plumbing work are left to the client or a separate contractor.

In a cascoopbouw project, the contractor is typically responsible for the shell, including foundations, framing, walls, roof, windows, doors, and basic utilities routed to the interior. The client or a dedicated interior contractor then handles interior walls, flooring, ceilings, fixtures, and fit-out details. This separation can also include rough-in installations for electrical and plumbing that allow later customization without delaying the shell.

The method is used to offer flexibility for owners who want to tailor interiors while achieving early occupancy or controlled shell costs. It is common in office buildings, housing projects, and commercial spaces where buyers or tenants intend to customize layouts or finishes.

Advantages of cascoopbouw include potential cost savings, faster overall project timelines for the shell, and greater customization for interior spaces. Disadvantages can include coordination challenges, potential for higher total cost due to fragmented responsibilities, and extended project duration for interior completion.

Related concepts include shell-and-core, shell delivery, and turnkey construction, which differ mainly in the scope of interior work and responsibility allocation.
