[https://www.mottmac.com/ Mott MacDonald] and [http://www.fairhurst.co.uk Fairhurst] were commissioned by Cheshire Police to design its new 2800m<sup>2</sup> headquarters in Blacon. Sustainability and energy efficiency were key objectives for this project along with cost and the need for a quick delivery. 

The team opted for a steel framed solution, rather than concrete, due to the relative cost and time savings the material offered. The steel framed building was designed to achieve [[Thermal_mass|thermal mass]], providing ‘inertia’ against temperature fluctuations.

Edward Murphy, Mott MacDonald Technical Director says: ''[[Thermal_mass|Thermal mass]] can, if designed correctly, be just as effective within an exposed [[Floor_systems#Precast_units|precast floor]] with a steel frame as it can within a concrete frame. In this instance we chose to use steel with precast because of the cost and time efficiencies that it offered''. 

As a result of using a steel frame to achieve [[Thermal_mass|thermal mass]], approximately 5% was saved on the cost over a concrete solution and the job was completed four weeks earlier than would otherwise have been expected.
