Cayman International School (CIS) major expansion was completed in 2019. APEC was the engineer of record on the original school campus, completed in 2006. The original school incorporated a multi-block classroom / laboratory wing with open-air circulation, an administrative block and a large multi-purpose hall. The wider campus included several sports facilities, including a swimming pool, sports field and tennis / basketball courts. The existing school was expanded in several phases in 2015, 2016 & 2017.
The major expansion included the construction of a single-storey early learning centre and a three-storey high school. APEC is the engineer of record for this and the associated civil works. The high school incorporates a central clear-storey atrium area flanked by classrooms / laboratories. There is a large gym encompassed in the high school also.
The clear storey design challenge was overcome utilising lightweight steel structure with a composite roof deck capable of withstanding the significant hurricane wind loads required by the local design codes. The overall structure incorporated a system of lateral bracing walls to resist the expected seismic / earthquake forces.
