Construction Period

2010 Q3 - 2011 Q2

The Ayala Centre Redevelopment was set to reinvigorate Manila’s Makati Commercial Business District. Acknowledged as a landmark development for the capital, Makati Development Corporation (MDC) turned to Gammon for industry expertise and management service capabilities to support their efforts in the pre-construction and construction process.

In 2009, Gammon was contacted by Philippines developer, Ayala Land to provide preconstruction services in collaboration with the Ayala Centre Redevelopment team. A team of four fulltime Gammon staff was subsequently assigned to work alongside the MDC team.

The redevelopment project comprised demolition of part of the existing Glorietta shopping complex and re-construction of a new shopping centre which was also connected to the existing adjacent operational shopping mall in phases. Rising above the new three-level retail spaces were two 7-storey office buildings and a 15-storey, 300-room hotel served by a district cooling system constructed as part of the development.

Opposite the new mixed use commercial development were three 50-storey high end residential towers serviced by four level basement car parks.

Construction Methods/ Temporary Works

Some of the most challenging aspects of the project related to the interfacing works between the existing and new shopping centre. One of the key interfaces was the development of the work sequence, construction methods and safe systems for the dismantling of an atrium roof structure connected to the existing building, cut and cover tunnel construction sequencing, steel structure erection methodology and the core climb forming system to the residential tower, plus, work sequence options for construction of the District Cooling System plantroom structures.

Design, Buildability and BIM

For the critical redevelopment of the EDSA Mall, Gammon’s BIM team assisted MDC with the production of a time simulated construction model for presentation to the owner and merchants to give them a better understanding of how the construction works would be carried out and the impact of the construction works on the adjacent operating mall.

Innovation

Innovative ideas were presented to MDC, including building services, bathroom modularisation, sustainable designs, time scaled 3D modelling/ BIM, and the application of ‘jump lifts’ on high rise buildings.

Procurement/Works Packaging

Large amounts of materials and products had to be procured from overseas, the majority through local agents. Gammon was working closely with MDC to identify China manufacturers who were able to supply similar quality products to those specified.

Building Services Engineering and Coordination

Gammon had assisted MDC with building services coordination relating the District Cooling System  plantroom, CSD/BIM reviews, Infrastructure services, modularisation, access and delivery routings, together with cross-checking of equipment schedules against the design drawings, sourcing and quotations for major equipment items.

Heath, Safety & Environment and Sustainability

The Gammon team worked closely with MDC through weekly inspections to identify hazards and develop safe working practices.

The Gammon sustainability team also made several presentations on ‘sustainable green construction’, providing examples of good practices being implemented on our projects in Hong Kong. Workshops were also held to brainstorm ‘green’ ideas and Gammon has assisted MDC to test an ‘acoustic blanket’ from China to reduce noise generated during demolition works.
