ULC Installatiegroep: Offices Hoog-Catharijne

Project presentation

    • Experimental site
    • Utrecht (The Netherlands)
    • Office building
    • Size: 107.000 m2
    • Renovation

 Predicted energy performance: 88kWh / m2year 


The project consists of retrofitting a building (offices and a shopping mall) for a real estate inves-tor. The building is located in the city centre of Utrecht, The Netherlands and is directly connected to the main train station (285.000 visitors per day). The mall and offices must remain operational during retrofitting and measure 107.000 m2. The building will ultimately be used by 30 million visitors per year.
The project is being executed by three main co-contractors: one for installations (ULC) and two for construction (AKOR and Boele Van Eesteren).

Training sessions

In two training sessions the main obstructions in information flow (from engineering to construc-tion) were identified. These results were used to setup ULC’s Pilot Field Lab. The trainees were all very familiar with using model viewers and working with information from the IFC-model. The workplace coach used the model (provided by the contractor and improved for installation use by ULC’s engineering department) to determine how the model and the information it contained could fit the needs of the blue collar worker better. The workplace coach also focused on integrat-ing quality control beforehand instead of afterwards (as is normally done).
