Advanced technologies, mechanisation of equipment with heightened safety features, and timely service and technical support to end-users can help the construction industry deal with construction complexities and pre-empt risks in different geologies and in hostile project sites. P.P. Basistha traces the latest developments and strategies of leading equipment manufacturers in meeting tunnel construction requirements of the contractors.
There is a series of metro, road and rail tunnels, water and sewerage projects lined up for development across the country, with close to 2,750 km of tunnel projects at various construction stages. Each project must contend with its own set of challenges posed by the geological terrain, some of which can be complex and critical in nature.
Since tunnelling is a highly cost intensive job, it requires timely progress, which is monitored by the project developers. For construction companies, the challenge lies in adopting various construction methodologies that achieve faster and better productivity, with very high levels of safety, while keeping operation costs low, and attaining the total lifecycle cost of the equipment.
