The final phase in the construction of the new R1,2-billion integrated terminal and R350-million new multistorey parkade at Cape Town International Airport is under way and joint venture (JV) contractors Grinaker-LTA and Stefanutti Stocks report that the project is on track for completion in April.
The construction of the striking new terminal was phased in to provide for the continued operation of the airport. “The completion and handing over of a project of this magnitude on time takes a major commitment from everyone involved. Each individual working on the final touches and cleanup of the building, from the client and their consultants to labour on site, has been dedicated to ensuring a problem-free opening. This has included working day and night shifts when necessary,” says JV representative Johan Brink.
The first phase of the new terminal was completed and the main terminal building was handed over to Airports Company South Africa (Acsa) in November, last year. Before the handover of the terminal, a number of dry runs were carried out to ensure that all systems were in place and ready to function when the first passengers came through to board their flights.
Further, a new multistorey parkade has also been constructed at Cape Town International Airport by the Grinaker-LTA/Stefanutti Stocks JV. This facility provides parking for 4 500 vehicles, which is close to double the parking capacity available in the original multi- storey parkade. Most of the parking area is now operational, reports Brink.
“Since the terminal opening, there has only been positive feedback from the general public using the facility,” he adds.
The construction of the vast 74 500-m2 new integrated terminal provided the JV contractors with a number of challenges. The decanting of various facilities, where the new building was to be built without impacting on the ongoing operations of the airport, was a challenge for the JV and for Acsa.
Subsequent challenges included working close to the public in an operational airport, the substantial growth in the scope of the contract as it progressed, the skills shortage, and the scale of the undertaking in the limited timeframe. Almost all underground services in the facility and the full length of the existing airport terminals from No 1 to No 5 on the land and airside had to be upgraded and relocated to make space for the new departure terminal.
The new building comprises piled foundations and a concrete framed structure ranging in height from three floors to five floors. The slabs are mainly post-tensioned, coffered and troughed, with about 12 000 m2 of slabs at high levels exceeding 8 m.
The roof structure is 22 420 m2 in size and the structural steel roof weights a total of 1 360 t. A total of 32 000 m3 of concrete has been used, along with 3 000 t of steel and more than 800 t of formwork.
The new integrated terminal will offer an additional eight new passenger loading bridges and a new elevated roadway along the front façade. It features an attractive, modern structural steel roof and concrete columns in an unusual ‘Y’ design. External civil works for the project comprised the elevated road for access to the check-in on the second floor, and 30 384 m2 of premix roads, as well as 32 000 m2 of brick-paved areas.
The integrated control systems are modern and specialised to ensure that Acsa’s two main aims of passenger safety and convenience are met.
“These systems were custom-designed and manage all the services provided, from air traffic control and flight monitoring to the new automated baggage handling system,” explains Brink.
Safety has been a priority throughout the contract, and the site team has maintained an impressive safety record. Achievements in this area have included winning first place in the Master Builders Association’s Regional Safety Competition for two consecutive years.
