CV: Putrajaya Lot 4G9

4G9 Tower (abbreviation for Precinct 4, Government Building, Parcel 9) designed for The Ministry of Information, Malaysia, is located on a strip of crescent shaped development site facing the Dataran Gemilang, a circular landscaped open space situated at the southernmost tip of the Core Island, Putrajaya. In the urban context, this 39 storey office building is part of a group of 4 towers earmarked to become the tallest structures to be built within the Core Island development.

In November 2003 a competition was organized by Putrajaya Holdings Sdn Bhd in which 10 Malaysian architectural firms were invited to participate. 3 firms obtained the commission for lots 4G9, 4G10 and 4G11; Jafri Merican Architect, Aqidea Architects and Hijjas Kasturi and Associates Sdn, respectively. The commission for Lot 4G8 was awarded to Juhari & Hashim Chartered Architects based on an earlier competition. Lot 4G9 was tendered as a design and build contract and was awarded to WCT Berhad. Completion date is targeted in late 2010.
The visual metaphor for the tower is based on traditional Malay artifacts and crafts, the curved side elevations recalling the shapes of ancient stone artifacts, and the diagonal shaped central façade pattern symbolizing a traditional form of textile craft, the ’songket’.

In order to translate these metaphors into buildable forms of specific measurable dimensions, a concept based on the Fibonacci Series is conceived as a form-giver to be used for shaping the tower. The series is a mathematical progression of numbers where the following number is the sum of two previous numbers; 1,1,2,3,5,8,13…. From this concept, a series of segmented façade surfaces is formed beginning from the roof, 1 storey, 1 storey, 2 storey, 3 and so forth to 13 storey for the lowest façade surface. These surfaces, formed of diagonal elements are then set in at different planes, and detailed by façade engineering consultants based on the unitized curtain wall concept. The sides of the tower, designed of precast RC fins with punctuated windows, serve as a counterpoint to the visually lighter Fibonacci façade.

The 4G9 tower building enclosure utilizes passive solar shading devices to achieve an Overall Thermal Transmission Value of lower than 45 w/m2.

4G9 Tower: Progress as at 16/2/2011

Regular monthly progress photographs. Tower cranes have been dismantled and works on the roof and skylight structure in progress. Interior works and tile laying still in progress but spray painting works hardly progressed since the previous progress photographs were taken on 17/1/2011. The Government offices in Putrajaya developed by Putrajaya Holdings Sdn Bhd is part of privatisation plan by the Government, implemented by UKAS (Unit Kerjasama Awam Swasta) based on a build, lease and transfer arrangement. Chapter 10 of the Ninth Malaysia Plan 2006-2010 under the heading 'Benefits of privatisation' stated that : 'Privatization also led to speedy delivery of facilities, such as in the development of the Federal Government offices in Putrajaya through the build-lease-transfer mode'.

Works proceeding with roof structure and external wall spray paint as the project nears completion. Culmination of the Fibonacci concept of the facade is taking shape as patterns formed by the external aluminium rods are progressively installed at the topmost floors.

4G9 Tower: Progress as at 8/12/2010

Work started on roof level canopy structure. Painting works on the external wall is still in progress.

4G9 Tower: Progress as at 5/10/2010

The fibonacci facade has by now progressed 5 floors since 6/9/2010. At this rate, completion of all facade works can be anticipated by end of December 2010. With fibonacci 3 segments being installed, the geometrical progression has become more apparent in the facade. WCT and Avos had done a commendable job in fabricating the facade, and we hope to see fibonacci 2 segment at levels 36 and 37, the highest two office floors, to be completed by next month, leaving the skylight structure of fibonacci 1+1 at the mechanical levels to be installed come December 2010.

4G9 Tower: Progress as at 6/9/2010

The Fibonacci curtain wall facades have progressed 5 floors since 10/8/2010 (Fibonacci 8 completed and 3 floors of Fibonacci 5 facade). With only 7 floors to go (2 floors remainder of Fibonacci 5, 3 floors Fibonacci 3 and 2 floors Fibonacci 2), and if WCT maintains the current rate of progress the facade may be completed by the 3rd week of October 2010. In November and December they could work on the skylight (Fibonacci 1 + 1 of the equation) and the roof covering for the maintennance gondola.
