CASE STUDY Project Summary Organization: CH2M Location: Singapore Project Objective: • Expand Changi WRP water treatment facilities within a limited footprint to meet future demand for NEWater and handle peak flow management without compromising feed quality. • Provide multi-discipline engineering services from detailed facility design through construction supervision and commissioning. • Minimize hazards and risks for safe, reliable plant operations. Products used: AECOsim Building Designer, ConstructSim, MicroStation ®, Bentley Navigator, OpenPlant, ProjectWise ®, and STAAD.Pro ® BIM Strategy Increases Treatment Capacity at One of the World's Most Advanced Water Reclamation Plants CH2M Selects Bentley’s BIM Advancements to Improve Efficiencies and Optimize Water Sustainability on SGD 400 Million Singapore Expansion Project Fast Facts • Using ProjectWise as the common interface and AECOsim Building Designer as the multi-platform design application to deliver information-rich deliverables enhanced information mobility, improving project performance, minimizing risk, and avoiding delays. • The automated publishing of i-models using Navigator accelerated accurate interdisciplinary design reviews for more coordinated modeling. ROI • Leveraging Bentley’s BIM technology, CH2M optimized design efficiencies and streamlined workflows among a multi-discipline project team. This eliminated errors, saved time, and reduced project costs while delivering the SGD 400 million Changi WRP expansion. • CH2M produced high quality models and visualizations that facilitated client engagement and allowed involvement of the end users early in the design process. A Pillar for Water Sustainability Located at the eastern end of Singapore, Changi Water Reclamation Plant (WRP) is one of the world’s largest and most advanced reclamation facilities capable of treating 920 million liters per day (MLD) of used water. The treated used water from Changi WRP is further purified to produce high-grade reclaimed NEWater, supplementing Singapore’s indirect potable and industrial water demands, which currently supplies 30 percent of the country’s demand. A pillar of Singapore’s water sustainability strategy, NEWater is expected to meet up to 60 percent of the country’s water demand. To accommodate future demand for used water treatment and produce a NEWater feed that meets water quality standards for biodegradable materials, suspended matter, and pathogens, which subsequently allows used water to be beneficially reused within the community to improve water sustainability and security, Public Utilities Board Singapore (PUB) initiated a SGD 400 million expansion of the Changi WRP. The expansion will increase the plant’s capacity by 200 MLD with a new liquid treatment facility and membrane bioreactor that produces a high quality filtrate to be used as the feed to a NEWater facility, as well as a new wet weather facility to handle peak flow. "With this expansion, Changi WRP will be one of the world’s largest membrane bioreactor facilities. More importantly, it will produce more treated used water effluent for NEWater production and increase our water recycling rate, which will allow us to ensure a robust and sustainable supply of water for Singapore’s future," said Yahya Abdul Ghani, PUB’s director of water reclamation (plants). PUB retained CH2M to provide multi-discipline engineering services for the Changi WRP expansion, ranging from detailed process and facility design through construction supervision and commissioning. CH2M faced a limited footprint for expansion, which necessitated a compact design to optimize land use and fully integrate the new treatment facilities with existing structures. Given the space limitations and the multidiscipline project team dispersed among three countries, CH2M needed to implement a collaborative BIM strategy to deliver the expansion plan on time and within budget. The automated publishing of i-models using Navigator provided the multi-discipline team real-time access to view the design at key stages in the project. BIM Strategy Accelerates Optioneering With numerous disciplines required to satisfy all technical, operational, and maintainable aspects of the plant expansion within a limited space, CH2M relied on Bentley’s BIM advancements, using AECOsim Building Designer as the multi-platform design application for analysis to provide rich information deliverables. Bentley technology fostered an efficient interdisciplinary approach, streamlining workflows and accelerating decision making. Working in a collaborative BIM environment using ProjectWise as the shared interface facilitated seamless integration of project data and models, which allowed early involvement of the entire team and the end users in developing the design. CH2M used the models during hazard and operability studies, and in access, lifting, and maintenance workshops to analyze the proposed design and discuss options relating to operations and maintenance of the expansion facilities with the existing plant. Bentley’s collaborative modeling and analysis software provided a vendor-neutral, adaptive facility design incorporating all possible equipment options, enabling effective optioneering and decision making to meet the various original equipment manufacturer (OEM) requirements. Furthermore, the ability to work within an evolving, federated design in real time enabled the multi-discipline teams to make decisions quickly and collaboratively within the specif
