A 900mm Jaspur trunk line discovered during pile cap work for Pillar No. 24 near Prahladnagar Junction has forced the corporation to spend ₹31.78 lakh on relocation.
Trunk Line Found During Pile Cap Work
Another coordination issue has surfaced during construction of the overbridge on SG Highway, raising questions over the planning of underground utilities before major infrastructure work begins.
During installation of the pile cap for Pillar No. 24 near Prahladnagar Junction, workers found that the 900mm Jaspur trunk line was obstructing the construction.
The line will now have to be shifted to another location, with the Ahmedabad Municipal Corporation set to spend ₹31.78 lakh on the work.
Why Was The Line Not Accounted For?
The discovery has raised questions about whether details of the existing water, drainage and storm-water networks were properly shared before the bridge design and pillar locations were finalised.
Before construction of a flyover or overbridge begins, maps showing underground utilities are generally made available to the agencies concerned. Pillar locations and structural designs can then be planned around existing lines.
In this case, however, the trunk line was identified only after work on the pillar had begun.
If the map showing the 900mm Jaspur line was available, questions arise over why the pillar location was not adjusted at the design stage. If the information was not shared, the incident points to a gap in coordination between the departments and agencies involved.
Corporation To Bear Additional Cost
The need to relocate the trunk line after construction has started means an additional ₹31.78 lakh will have to be spent.
The issue also highlights the financial impact of incomplete coordination in large infrastructure projects. A utility line that could potentially have been accounted for during the planning stage now requires separate shifting work after the bridge construction has progressed.
Similar Problems In Earlier Bridge Projects
This is not the first time underground utility lines have created complications during bridge construction in Ahmedabad.
Similar problems have emerged during work on the Makarba and Vejalpur railway overbridges, where inadequate information about underground water and drainage networks resulted in disruptions, design-related issues and the need to shift existing lines.
With bridge projects involving expenditure running into several crores of rupees, such utility-related obstacles can add both cost and delays.
The latest incident on SG Highway has once again brought the need for better coordination between civic departments and construction agencies into focus, particularly before pillar locations and structural designs are finalised.
