Throughout the conceptual and detai led des ign phases the team made use of Revi t Model l ing / Draught ing as the primar y sof tware to ensure detai led cons i stency was maintained. Addi t ional ly, a Bui lding Informat ion Model l ing (BIM) plat form was used for the des ign and analys i s of al l civi l and structural engineering components , preparat ion of construct ion documentat ion and quant i ty take-of fs . The team also worked closely wi th the cl ient to ensure successful project construct ion execut ion. Al l project del iverables have been in l ine wi th cl ient ’s expectat ions and in accordance wi th coordinated archi tect and bui lding ser vice consul tants’ drawings and speci ficat ions . Some of the innovat ive des ign features of thi s project are in relat ion to the l ink bridge between Bui lding A+B.

The ACSA Western Precinct Of fices (AWPO) i s a new turn-key commercial development s i tuated adjacent to OR Tambo Internat ional Ai rport . AWPO forms part of ACSA’s strategy to expand the ai rport ’s of fering and to drive new sources of growth for the ent i re region. Construct ion started in May 2019 wi th pract ical complet ion achieved in June 2021. The bui lding compri ses a 5 storey parkade for use by both the publ ic and AWPO tenants . The parkade also forms the base of a landscaped podium level , upon which three sculptural bui lding forms are located. These bui lding forms provide whi te-box of fice space for ACSA, the South Af rican Civi l Aviat ion Authori ty (CAA) and a future tenant . The object ive of the bui ldings forming separate mul t i -tenant spaces i s to turn the precinct into the neighbourhood's new landmark whi le maintaining vi sual harmony wi th the surrounding envi ronment .

Some of the chal lenges posed during thi s project included that the s i te i s located on a previously shaded carport parking area pos i t ioned between main entrance roads to the ai rport , and the construct ion planning needed to factor in cont inuous traf fic to and f rom the ai rport . The s i te also presented chal lenging ground condi t ions wi th a high-water table that requi red the use of dump- rock and cont inuous fl ight auger pi les for the foundat ion construct ion. Whi lst the bulk earthworks was in progress a sewer main l ine was di scovered, the relocat ion of thi s exi st ing ‘ l ive’ sewer l ine ser vicing the ai rport precinct requi red careful planning to ensure uninterrupted ser vice to the ai rport .
