Asset trust and building plant, one contract

ADOS B.V. holds commercial and industrial property in trust and installs the ventilation, power, automation, and security that keep those buildings running.

Asset value and engineering

Stewardship and installation sit in the same file

Owners usually hire a manager, then a separate installer for every rebuild. ADOS keeps care of the asset next to the crew that designs, mounts, and commissions the plant.

Trust side

Holding the asset

  • Day-to-day operation of commercial and industrial buildings
  • Decisions that protect capital value, not only this year’s rent
  • One contact for owners who do not want a stack of vendors

Plant side

Fitting the building

  • Specification, mounting, and commissioning of engineering equipment
  • Ventilation, air conditioning, power supply, automation, and security
  • Rebuilds done by the same company that already runs the property

The aim of this pairing is lower running cost — up to 30 percent — by dropping the extra vendors between management and the plant room.

What we take on

Four lines of work, written for the building you already own

Each line is scoped on site, then carried through to a signed handover.

  1. Trust management

    ADOS takes operational care of commercial and industrial assets: occupancy questions, vendor coordination, and the capital plan. The brief stays with the owner; the daily file stays with us.

    A replacement air handler or switchboard is priced against the asset, because the same office specifies the plant.

  2. Ventilation and air conditioning

    We design, mount, and commission supply and extract air, plus cooling for offices, halls, and process rooms. Duct routes and plant location are drawn before anyone opens a ceiling.

    Commissioning includes measured airflow and a written record of setpoints for the next service visit.

  3. Power supply

    Distribution boards, feeders, and the electrical side of mechanical plant go live under the same contract as the air systems they serve. Loads are listed before cable is pulled.

    If a rebuild changes demand, the power drawing is updated with the mechanical drawing, not months later.

  4. Automation and security

    Building controls, alarms, and access sit on the same schedule as the equipment they watch. We mount the devices, prove the points, and leave a list of what each point does.

    Security and automation are commissioned with the ventilation and power, so opening day is one visit.

What you receive

A commissioning file, not a handshake

When installation finishes, the owner gets a set that matches the plant in the room. That file is the baseline for trust management afterward.

  1. Survey notes

    Room sizes, existing plant, and structural limits, written before equipment is ordered.

  2. Install drawings

    Duct, pipe, cable, and device locations, marked up if the site forces a change.

  3. Test sheets

    Airflow, electrical checks, and control-point proofs, dated and tied to equipment tags.

  4. As-built and setpoints

    The record the trust desk uses when a tenant calls or a later rebuild has to match what is already there.

The company

A Groningen desk that also owns the spanners

ADOS B.V. opened in 2025 at Romerostraat 16, 9746 BA Groningen. The work is trust management of commercial and industrial assets, plus the engineering fit-out those assets depend on.

Most managers phone an installer when roof plant fails. We already hold the drawings, because we mounted the equipment or surveyed it. Rebuilds stay inside one contract.

Albert Doornbos takes new instructions at [email protected] or +31 6 3478 0823. Name the building, the city, and whether you need stewardship, a plant install, or both.

Where we work

Based in Groningen, on Dutch commercial plant

The office is in Groningen. Site visits start from Romerostraat. Commercial offices, industrial halls, and mixed buildings are the assets we take; houses are outside the brief.

If the property sits elsewhere in the Netherlands, say so in the first note. We confirm the survey date before anyone is booked onto site.

Questions

Before you send the building address

Can you manage the asset without installing plant?

Yes. Trust management can stand alone. Later ventilation, power, automation, or security work stays with ADOS.

Can you install plant without taking the management?

Yes. Specification, mounting, and commissioning can be a single job. Many owners then ask us to keep the file, because the test sheets are already on our desk.

Where does the “up to 30 percent” figure come from?

It is the running-cost cut ADOS aims for when management and installation are one contract. It is a target of the model, not a promise on every building.

What should the first message include?

Building type, city, trust management or an installation, and a phone number. We reply from [email protected] and propose a survey before quoting equipment.
