Paya Lebar Quarter(PLQ) Digital Twin, Singapore – A Smart Precinct Case Study
Paya Lebar Quarter (PLQ) is a Green Mark Platinum rated mixed development by Lend Lease, comprising 3 Commercial Towers, a Retail Mall and 3 Residential Blocks. The project is being completed in stages with the 335,819 sq. ft. Tower 1 completed in August 2018; the 547,658 sq. ft. Twin Commercial Towers (Towers 2 and 3) in February 2019; and the 310,000 sq. ft. Retail Mall was completed in August 2019.
PLQ Smart Building Solution
PLQ will be operated as a Smart Precinct through a single technology platform called the Open Building System Integration (OBSI) platform based on Eutech’s iviva software. The OBSI platform connects all building systems and equipment across the commercial towers, retail mall and precinct infrastructure including air-conditioning and mechanical ventilation, electrical, fire, car park, CCTV, lift, access control and people counting. These systems are integrated with the 3D BIM models to create a “Digital Twin” of each building and the precinct.
The Digital Twin is a working digital replica of each building’s physical spaces, equipment, systems and infrastructure processes (the Physical Twin) and serves as an intelligent interface to the Physical Twin for smart operations and maintenance. Dynamically assembled operational dashboards and 3D BIM visualization enhance the management of critical alarms and the effectiveness of exception-based management and predictive, condition-based maintenance of systems and processes
A unique feature of the PLQ Smart Precinct project is the use of the iviva Commission to Operate (C2O) process to simplify the delivery of the Physical and Digital Twins. C2O automates the connection, integration and commissioning of the building equipment, systems and spaces, ensuring that they are operationally ready for handover. Post handover, C2O ensures continued operational efficiency through the continuous commissioning of equipment, systems, operational processes and spaces.
OBSI serves multiple stakeholders including tenants, building and facility management teams, engineering and commissioning teams and contractors. Building and facility management teams will use OBSI for their day to day operations.
