Like many countries around the globe, Indonesia faced soaring COVID-19 cases towards the start of the pandemic that exceeded hospital bed capacity. To address this shortage, the Indonesian Government initiated plans to construct 14 new hospitals. PT. Wijaya Karya (WIKA) was tasked with building one of them on a 22,700-square-meter former soccer field in South Jakarta. The USD 4 million hospital is a one-story building with a capacity of 300 beds, 35 intensive care unit rooms, and 10 emergency rooms.
The state-of-the-art facility is equipped with a negative pressure isolation (NPI) system to prevent the flow of virus-contaminated air, eliminating the spread of infectious pathogens to the surrounding environment, and includes a robotic nurse and an integrated command center to connect it to 65 other hospitals. Given the critical pandemic situation, the government tasked WIKA to complete design and construction works, as well as have the hospital fully operating, in less than a month (Figure 1). Delivery also needed to be cost-effective and environmentally sustainable. The project was completed in May 2020.
WIKA established a connected data environment using ProjectWise and adopted Bentley’s reality modeling and BIM methodology to carry out their modular approach. They used a quadcopter drone to capture images of the two-hectare project site and used ContextCapture to process them, creating a reality model of the topographic area. With OpenBuildings Designer, they generated a model of the entire hospital building, including structural, architectural, and MEP elements, and used OpenRoads to incorporate landscape and roadway design (Figures 2 and 3).
To optimize the design of the indoor airflow system to support patient recovery and prevent viral transmission, WIKA used Hevacomp to perform airflow analysis and simulation within the building model, designing an HVAC system that complies with proper standards (Figure 4). They integrated the 3D models with the construction schedule and costs using SYNCHRO 4D and animated the model with LumenRT, improving construction visualization and design verification (Figure 5).
As a pioneer in modular construction in Indonesia, WIKA strived to push the boundaries of design and construction through their innovative use of engineering, architecture, and construction applications. Modular design and construction not only accelerated construction time, but also increased quality, safety, and sustainability by using offsite, factory-controlled processes and lightweight, mostly recycled materials. Since Bentley’s engineering, architecture, and construction applications can be used for a wide array of infrastructure types, WIKA easily adapted them for the design and construction of all modular components.
Yes, because WIKA was able to develop and build the modular hospital in a very short amount of time at a low cost and a high level of quality. By developing and implementing digital BIM workflows, WIKA completed 95 design revisions and resolved 62 clashes in three days, delivering the modular design in only 10 days and saving USD 400,000. With digital simulation, they were able to streamline the process and reduce construction time by four days to complete the project within 16 days – 20% faster than targeted.
Working in a unified BIM platform, WIKA provided complete insight into planning, costs, scheduling, and construction, improving cost efficiency by 18% while optimizing quality. Integrating their modular approach using a BIM methodology, WIKA increased its return on investment by 24% and accelerated hospital operations by two months. The ability to extract accurate material quantities from the 3D models — combined with the sustainability of the modular construction process — contributed to saving up to 3,000 cubic meters of material waste and 10% of project costs.
With lives at stake, time was of the essence. As a multidiscipline engineering project with a socially distanced team, WIKA needed to quickly coordinate engineering, structural, architectural, mechanical, and plumbing works to facilitate simultaneous design and construction, and to meet the tight delivery schedule. Additionally, WIKA’s modular system is challenging to execute, requiring streamlined processes and complex decision-making to meet project deliverables.
No, WIKA was able to overcome all challenges and meet all project requirements by using a variety of Bentley’s specialized AEC applications.
Because WIKA’s development and construction of the South Jakarta modular hospital with engineering, architecture, and construction technology was such a success, the company subsequently used the same methodology to construct additional modular hospitals as quickly as possible to help save lives during the pandemic.

In the wake of the current coronavirus pandemic, this article highlights the impact of the crisis on the AEC industry so far, the response to it from AEC technology, and how it might change the nature of our industry in terms of what gets built, how it will be designed and constructed, and the technology that will be required to support it.
This article describes the research that was conducted by a team at the Technical University of Denmark to study the impact of COVID-19 on the passenger flow in the Copenhagen Metro, using passenger flow data and station floorplan drawings as well as Bentley Legion software for simulation of pedestrian flow.
Now that the AEC industry has had several months to settle in a COVID-19 reality, Stephen B. Jacobs, the founder of the SBJ Group, discusses where we currently stand and what proactive measures designers can implement as we build and adapt in a new abnormal.
In this article, Kenny Ingram, Vice President of Engineering, Construction & Infrastructure at IFS summarizes some key trends that he believes will color 2021 and beyond, including lifecycle management, offsite construction, and 5D BIM.
