Digital project management helps save $18 million to Maha Metro
Project delays, time and cost overrun in infrastructure projects, delays in regulatory approvals, contractual disputes, etc., are some of the challenges faced while implementing a project in India. However, this is not the case with Nagpur Metro. The Nagpur Metro project—with the help of digital project management—has delivered huge benefits to the project. Here, Nagpur Metro’s main focus was on asset lifecycle rather than project management.
Speaking during the recently-concluded The Year in Infrastructure 2017 event, organized by Bentley Systems in Singapore, Dr Brijesh Dixit, Managing Director of the Maha Metro Rail Corporation (MMRC), said, “We have achieved around 12% cost savings w.r.t logistics, travel and many days, and it is expected to rise to 15%.” He added: “Around 8% savings in time has been achieved so far and it is expected to touch 11%.”
That said, the Nagpur Metro is likely to achieve the reduction in overhead costs from 5% to 3.5% by the end of the project. While other metro projects are going ahead with a 10.5-m (meter) viaduct, Nagpur Metro opted for an 8.5-m viaduct, which helped them save around $18 million. In addition, MMRC saved around 8.5 per cent on DPR of the project cost and around $60,000 on Metro Bhavan HQ because of early detection of quantity overrun through BIM mode and clash detection.
What’s more! Due to the optimal design of sheds, stabling lines, inspection bay lines and repair bay lines, MMRC has saved around $15 million avoiding delays through BIM mode planning. Dixit added, “The digital project management in planning has benefited an effective utility shifting, optimal ROW planning and importantly, effective land acquisition.”
