Deerns

In the field of electrical, mechanical and energy engineering solutions and building physics, Deerns is one of the largest independent consultancy firms in the Netherlands.

With eleven offices in the Netherlands, Germany, Dubai, Spain and the United States, Deerns is internationally a trend setting company.

Deerns’ work in a project may start consulting the client regarding his schedule of requirements. From this we develop the primary technical concept of the building, generally in cooperation with an architect; this is then detailed into the actual design – from concept design via provisional design to detailed design plus cost estimates – and on to the preparation of contracting documents: a set of specifications and specs drawings, and bills of quantities.

Subsequently, Deerns assists the client in the process of contracting: it invites bidders, performs the selection process and prepares the contract. The final step for Deerns is the oversight and direction of the contractors who carry out the building process.  In many assignments Deerns does not carry out all of these activities; we are often asked to provide services in only part of these stages.
Deerns is also involved in many renovation and refurbishment projects that differ in certain aspects from new construction projects.
