Davy Sukamta & Partners is making history as the first Indonesian structural and foundation engineering firm to fully design a super-tall building Writer: Matthew Staff Project Manager: Tom Cullum

he first super-tall structure and foundation designed by a Jakarta-based consulting engineering firm is currently under construction in the capital city of Indonesia. The design of this 303 metre building with seven-level basement structure was being pushed to new heights by applying the right balance between advanced innovations and local considerations including material availability and construction practice. Customary to most super-tall developments, almost all key players including developers, architects, MEP

consultants and general contractors - are international-based firms; with a unique exception to the Jakarta-based engineering firm, Davy Sukamta & Partners (DS&P). The international developer has commissioned the design and supervision of this 63-story Indonesia-1 Building to DS&P. The Company utilises top-down construction for Jakartaâ€™s deepest basement with RC core-wall and outriggers as the lateral resisting system. Using various innovations from post-grout bored-pile to the design of super-structure with a performancebased approach, DS&P demonstrates a full commitment in responding to

A high-performance organisation

P A R T N E R S

In 1996, DS&P became the first structural engineering firm to receive ISO 9001 certification in Indonesia; emanating from the business’s vision to build a better future for every stakeholders; from the society as the users of the buildings, to the client as the developer, to the contractors who use the design, and to the employees of DS&P. The mission is to always advance in designing better structures. Being a small firm with 24 people in the design department and 10 in supervision, it is interesting to understand how DS&P can handle big scale prominent developments with evident success throughout the

decades. However, the key to the Company’s success derives from its establishment of a high-performance organisation concept within the Company. DS&P believes that key to being a high-performing Company is the quality of the people. Therefore, it highly values the people within their organisation. The firm encourages a growth mindset to staff by providing a work environment that can allow employees to grow and flourish in becoming innovative and experienced engineers with high job satisfaction. This is achieved through continuous education programmes, effective management of workload and

Lessons learnt are well-documented for continuous improvement. This is the reason why DS&P is capable of producing design to high-quality standards and detailing that can comply with stringent seismic detailing; stipulated by codes while maintaining practicality in construction. The use of dialogue with architects further results in a better structural configuration while keeping the architect’s design intent at the same time.

The following narrative highlights the list of innovations and achievements they have made.

Set the trend

Topdown constrcution in progress

WWW.ASIAOUTLOOKMAG.COM

In 1993, DS&P used high capacity bored-pile up to 550 tonnes allowable load while the normal practice at that time was around 350 tonnes. In 1994, DS&P designed the first RC core-wall and outriggers structure. In 1995, DS&P designed the Gran Mahakam hotel with top-down method, excavating 11-meter deep just 1.5 metres away from two-tothree-story neighbouring buildings. DS&P also designed the first building in Indonesia beyond 50 levels in 1994, the 52-story Amartapura Residential towers. At that time DS&P pushed the concrete grade to 60 MPa for that development when the common grade was just 25-35 MPa, and then recently to 70 MPa for Indonesia-1. In order to obtain reliable quality, DS&P worked closely - and still does - with ready mix suppliers in an experimental programme to obtain valuable on-site data. The role of business partners in advancing new technology is indispensable as such.

Pakubuwono Development

With such mutual collaboration, DS&P is able to set the trend in the construction industry in Indonesia including higher grade concrete, the use of post-installed anchors to transfer forces, crystalline barrier waterproofing for white tanking of basement structure, and the use of chemical admixtures and minerals to obtain the required concrete properties. Throughout its practice, DS&P has promoted numerous first-time design and construction applications in Indonesia. Examples include the

use of the sacrificial cell method to load-test bored-piles for Pakubuwono Residence in 2003; the use of post-grout techniques to increase the allowable capacity of the bored-pile for the Plaza Indonesia Extension (PIE) project in 2006; the use of micro piles with soilsupported mat to resist tensile force from hydrostatic pressure for the Trans Luxury hotel in Bandung in 2009; the design of the first high-rise building with seismic isolation in Southeast Asia in 2010, the use of Performance-Based Seismic Design; and the design of the

super-tall 63-story Indonesia-1 with the deepest basement structure in Indonesia in 2014.

The first

PIE was designed for up-down construction in 2006, where upon the completion of the fifth and last basement level, the super-structure work was progressing at level 11. This method saved 11 months construction time. The two residential and office towers, 48 and 42 stories high, with sixlevel podium and five-level basement

were able to be completed in 36 months because of this method. This is the first successful application of the up-down method in Indonesia. Up to the present day, DS&P has designed nine deep basement structures with top-down or up-down methods, the deepest being the seven-level 25-metre deep excavation for Indonesia-1. This method of construction requires careful planning on the sequence of work and detailing of plunged king-posts. DS&P uses highend analysis technique for this type

of job and the frequent observations and recordings from various projects bring advancement to the state-of-theart designing top-down method for Indonesian conditions. Collaboration with piling and general contractors once again results in continuous improvement of this method. DS&P has helped some general contractors in solving the deep basement design, including one value-engineering job for the six-level basement structure of Sequis Tower project previously designed by a US-

PT PP (PERSERO) TBK

T PP (Persero) Tbk (IDX: PTPP) is the oldest and one of the largest construction and investment SOE companies in Indonesia, established in 1953. For more than six decades, PTPP has successfully completed various projects across Indonesia, including monumental buildings and infrastructures. In 2010, PTPP listed its shares for the first time on the Indonesian Stock Exchange (BEI). Since then, PTPP has diversified its activity through seven business pillars grouped into three categories. Upstream business includes property, infrastructure investment, and energy investment. Midstream business includes construction services and EPC (power plant, resources). Downstream business includes precast and equipment.

based engineering firm. The experience in design and construction of these projects has been presented as technical paper in international forums including the Council on Tall Buildings and Urban Habitat (CTBUH). The use of seismic isolation systems is another novelty in Indonesia, especially for high-rise buildings. One client requested DS&P to design their new 22-story Gudang Garam office tower using this system in 2010, after

a series of earthquake events shaking Jakarta. The first high-rise with seismic isolation in Southeast Asia was then borne, followed by the 27-story Puri Matahari in 2012. Both buildings were designed using high-damping rubber bearings by DS&P. While the use of steel or composite construction for high-rise buildings in Indonesia is not popular, DS&P recognises its advantage and has become the leader in promoting its use.

The stocks of the property subsidiaries of PTPP have grown significantly above the industry average, indicating public trust over the companies’ performances. Both companies’ stocks have been included in the Morgan Stanley Composite Index. Since January 2014, PTPP stock has also been included in the LQ45 index. Aligned with the Indonesian Government’s commitment to boost infrastructure and SOE companies’ role in the development, PTPP has strong opportunities to expand its business. Equipped with experience and capability in construction and investment, allied with strong public interest in PTPP’s stocks and a vital role as a nation development agent, PTPP now looks further afield to expand with the aim to be the largest construction Company in the ASEAN region in terms of equity by 2018. PTPP is building a strong presence in ASEAN, as shown by numerous regional and international accolades received in 2016 and since has set its vison to become a sustainable ASEAN-class construction and investment Company.

MR SAFETY GROUP Composite construction for the City Tower

The Company has designed a number of projects with concrete and steel as the structural material. The City Tower, a 30-story office building with RC corewall and steel gravity framing, set the record for speed of construction by completing 30 stories in four months. Gudang Garam and Puri Matahari are two other high-rises with the same structural framing material. The details used in these steel structures meet the seismic requirement of AISC. Currently, DS&P is designing a theatre and convention building with a three-tier theatre comprising 2,400 seats and two ballrooms at 2,850 and 950 square metres each. The design of the complex structure with longspan transfer trusses is an engineering feat in its own, not to mention the seismic design strategy adopted in accommodating the intricate layout.

In order to maintain highperformance services, a limit is provided to the number of projects taken on, with careful planning and consideration on available resources. Contrary to a conventional business way of thinking, the Company would not hesitate to turn down projects if its resources have already been absorbed in other ongoing projects. With limited projects in-hand, DS&P is able to provide a first-class personalized service to the clients, giving full commitment with passion. No time limit is set to finish a job; it must simply be performed to optimum satisfaction. This explains that despite the high fee, the business has managed to become the â€™destinationâ€™ consultant of smart developers who value high quality service and end results rather than the cost of the design fee. Almost all projects are awarded through direct appointment from a host of loyal clients.
