We were appointed by the Government of Antigua to study the physical and financial feasibility of upgrading airport facilities by adding parallel taxiways, strengthening, and extending the runway, and implementing rehabilitation works to aircraft aprons, airfield lighting and the terminal building. Upon completion of the studies, we produced detailed designs and supervised construction of the works.The Grenada Airports Authority recognized our capability to control construction works on operational international airports and appointed us as Design Approval Engineers and Construction Supervisors on their Turnkey project to upgrade and extend the Point Salines International Airport terminal building and aircraft aprons and to carry out rehabilitation works to the runway pavement and threshold sea defenses.
