Using AI at Halsen School: Reduced Construction Costs by 20 Million NOK
Optimising the plant rooms and technical ceiling grid, and assessing the programmed area compared to the designed area.
Consigli's optimisation products were used towards the last part of the collaboration phase in the construction of a school, before shifting to a D&B contract. Consigli's delivery consisted of optimising the location and extent of plant rooms on the roof, and the technical system in the ceiling, as well as assessing the programmed area compared to the designed area.
Consigli generated solutions for one centralised plant room on the roof, whereas the initial proposal consisted of two separate rooms. The optimised design merged the plant rooms while also reducing the required area by 90 m2. Additionally, O&M was improved by having streamlined access to technical components, enabling all service to be carried out within the same room.
There was no ceiling grid, nor technical components in the ceiling plan at the time of Consigli’s optimisation. Consigli proposed a cross-disciplinary coordinated ceiling grid for ventilation and sprinklers for all floors, in addition to an optimised pathway for the duct network above the ceiling. This solution reduces future engineering hours required for cross-disciplinary designing of ceiling plans.
The designing group for the school had made several attempts in reducing the footprint of the building, targeting potential cost reductions. Consigli made a comparative analysis of the programmed area and the designed area, revealing all discrepancies between the two. The results were presented to the client, providing insight into which areas could be optimised for potential space reduction. Based on the client’s preferences, Consigli generated an optimised floor plan with a reduction of the excess gross area of 180 m2. The proposed floor plan provided valuable insight enabling the contractor and client to make qualified decisions for the potential area and cost reductions.
