PANJIM: The Imagine Panaji Smart City Development Ltd (IPSCDL) achieved a significant milestone with the completion of the construction of a crucial manhole located near the Sheetal Hotel at St Inez “Y” intersection.
This infrastructure project, featuring a depth of four metres and a diametre of three metres, represents a major engineering achievement despite numerous challenges, the IPSCDL said.
According to the IPSCDL, the excavation process was particularly delicate due to the presence of several critical utilities duea to laying of gas pipeline passing through the excavation chamber. It also took precaution to ensure that the existing sewage pumping line, which transports sewage from the Don Bosco School pumping station to the Sewage Treatment Plant (SWTP), was carefully preserved and also protecting electrical cables and internet cables. To protect these utilities, manual excavation was conducted, ensuring the safety and integrity of existing services, it said.
Narrating technical a, the IPSCDL stated that the manhole’s location at a busy junction required the connection of three pipes i.e. one from the Vivanta By Taj, one from the Madhuban junction side and the third going towards Caculo Mall.
The overhead existing pumping line posed challenges for tying reinforcement and conducting concreting work. Special strategies were employed to manoeuver around these obstacles.
The three-metre diametre of the manhole, larger than the typical two-metre diametre, required special form work. This was sourced and implemented to facilitate the concreting process.
Despite all these complexities, the project was completed without damaging any utilities, showcasing the team’s expertise and commitment to excellence.
A top IPSCDL official said that the completion of this manhole was a testament to its commitment to enhancing the city’s infrastructure with precision and care.The completion of this manhole improves the a and reliability of the local infrastructure, contributing significantly to the city’s overall development, he said.
