Why do Revit and BIM make installation execution easier?

Installation designs for contractors — Revit, BIM, and the model as an installation tool

The execution of building services on site requires documentation that is not only technically correct, but also practical for the contractor. That is why we prepare MEP installation designs in Autodesk Revit, using BIM capabilities not only for 3D modelling, but also for providing the contractor with specific information needed during installation, material ordering, prefabrication, and work coordination.

We create installation models that can include additional parameters tailored to the contractor’s needs — for example, information about the system, floor, building zone, room, element type, diameter, dimensions, insulation, material, device number, installation stage, procurement package, or prefabrication area.

As a result, the project is not just a set of 2D drawings. It can become a digital database of installation information used by designers, coordinators, site managers, procurement teams, and installers.

3D model available to the contractor

Upon request, we export the model to IFC or another agreed BIM format, which can be shared in the cloud or viewed in a model viewer. This allows people involved in the project execution to view the installation in 3D on an ongoing basis — without the need to work directly in Revit.

In practice, this means that the contractor can open the model, review the installation routes, zoom in on difficult areas, create sections, check relationships between disciplines, and click on a selected element to view its parameters. Autodesk Construction Cloud allows users to view 3D models, take measurements, analyse sections, and access element metadata, while independent IFC viewers make it possible to open IFC models exported, among others, from Revit without needing a commercial design software licence.

For installation teams, this is especially useful in areas where a 2D drawing does not show the full context: shafts, service corridors, plant rooms, above suspended ceilings, technical rooms, boiler rooms, heat exchanger rooms, and other complex technical spaces.

Documentation adapted to installation

A 3D model makes it much easier to understand where installations are routed, how they interact with the structure, architecture, and other disciplines, and in what sequence individual elements should be installed.

Based on the model, we can prepare additional views, sections, details, and studies for areas that are particularly difficult from an installation perspective. We are not limited to a few standard sections — if needed, we can generate a larger number of sections through specific parts of the building, technical rooms, collision-prone installation routes, or areas requiring a precise explanation of the installation method.

We can also prepare 3D views for specific building areas, for example separately for a floor, zone, shaft, technical room, or the scope of work assigned to a particular installation team.

Advanced material schedules

One of the greatest advantages of working in Revit is the ability to generate schedules directly from the model. These schedules can be filtered, sorted, and grouped according to parameters stored in the model elements. Revit allows the creation of quantity schedules and the addition of custom parameters, which makes it possible to build schedules tailored to the contractor’s actual workflow.

Thanks to this, we can prepare material schedules broken down not only by discipline or installation type, but also by:

• floor,
• part of the building,
• installation zone,
• room,
• installation system,
• execution stage,
• procurement package,
• prefabrication scope,
• selected contractor or subcontractor,
• specific part of the investment.

This approach significantly simplifies ongoing material ordering, delivery planning, quantity control, division of work between teams, and prefabrication preparation. Instead of one general schedule for the entire building, the contractor can receive schedules that reflect the real organisation of the construction site.

Fewer clashes and fewer uncertainties on site

Working in a BIM environment allows clashes between installations, structure, and architecture to be identified earlier. Clash detection in the model helps reduce costly corrections, delays, and changes made only at the construction stage.

For the contractor, this means greater predictability during installation. Installation routes can be analysed, coordinated, and presented in a way that is clear for the people responsible for execution.

Information stored in model elements

Each installation element in the model can carry additional information. Depending on the project’s needs, we can enrich the model with parameters useful for the contractor, such as:

• system name,
• circuit or installation number,
• floor and installation zone,
• room,
• type of equipment or fitting,
• diameter, dimensions, material,
• insulation,
• flow rate, power, capacity, or other technical data,
• schedule number,
• installation package number,
• execution stage,
• prefabrication information,
• installation notes,
• markings for inspections and as-built documentation.

This allows the model to be adapted to the way a specific contracting company works. The procurement department needs different information, the site manager needs something else, and the installer on site needs yet another type of data. In Revit, we can structure the data so that it supports each of these processes.

Possibility of preparing installation packages

For larger or more complex projects, we can divide the documentation into logical installation packages. For example: installations for one floor, one zone, one shaft, one technical room, or one part of the building.

Such a package may include:

• plan drawing,
• sections,
• 3D view,
• material schedule,
• list of equipment and fittings,
• installation notes,
• exported model fragment.

These packages are more convenient for the contractor than one large set of documentation covering the entire building. They make it easier to organise work, order materials in stages, and provide specific teams only with the scope they actually need to execute.

Prefabrication support

A BIM model can also be prepared with prefabrication in mind. This is especially useful for repetitive installation sections, routes in corridors, installation modules, shafts, technical rooms, and modular construction.

We can mark elements according to prefabrication sections, prepare schedules for specific modules or installation fragments, and develop views showing how prefabricated elements should connect with installations executed on site.

More up-to-date and consistent documentation

Working with a model helps reduce the risk of inconsistencies between plans, sections, schedules, and 3D views. If the project is managed correctly, changes in the model can be reflected in the documentation and schedules, which reduces the risk of working with outdated information.

For the contractor, this means better control over changes and easier comparison between successive versions of the documentation.

What can the contractor receive?

Depending on the scope of cooperation, we can prepare:

• MEP execution design,
• Revit/BIM model,
• IFC model for viewing in the cloud or in a BIM viewer,
• installation plans and sections,
• additional sections through difficult areas,
• 3D views for installation teams,
• material schedules broken down by floors, zones, rooms, or stages,
• schedules of equipment, fittings, ducts, cables, pipes, and fittings,
• installation packages for specific parts of the building,
• documentation for prefabrication,
• as-built model,
• design support during construction.

Who is this for?

We support installation companies, general contractors, specialist subcontractors, and companies involved in prefabrication and modular construction.

We can join the project at the tendering stage, coordination stage, execution design stage, workshop documentation stage, or already during construction, when technical issues need to be solved quickly.

A project that works together with the contractor

Our goal is to prepare documentation that does not end with a set of printed drawings. We design so that the model and documentation can genuinely support the contractor — in coordination, procurement, prefabrication, installation, change control, and handover.

A well-prepared BIM model helps contractors better understand the installation, make decisions faster, and reduce the number of questions and uncertainties on site.
