Catholic Education Office (CEO) Building
This project consisted of the design and construction of a new office building for the Catholic Education Office, and refurbishment of an existing heritage facility that is integrated into the new extension. JHA was engaged for mechanical and electrical (including dry fire, communications & security) services, and delivered the project from master planning stage through to construction stage. Working within the heritage building presented a number of challenges, with presence of asbestos and numerous architectural feature elements with high heritage value. The JHA team worked with the architect to provide new mechanical and electrical systems that were concealed in non-heritage locations, and achieved cost efficient outcomes for exposed services that blended in with the architectural intent. JHA also undertook site infrastructure analysis, and delivered infrastructure upgrades to electrical power and communications systems, as well as master planning the site for future stages of upgrades for the client.
