Planning a major initiative to improve the road conditions and come up with elevated corridors and flyovers in the city, the GHMC has decided to rope in consultancy services for geo-technical investigations along major corridors.
Under the Strategic Road Development Plan for Hyderabad, the civic body has invited technical and financial proposals from consultancy services for a series of activities aimed at understanding the soil, rock and groundwater tables at crossing of railway lines, national highways and power lines along major corridors.
The detailed geo-technical investigation sought for roads include trench pit analysis to be carried out at the interface of earthen shoulder and bituminous road, thickness and type of sub-base while identifying thickness and type of sub-base and bituminous courses at every one km interval. For locations being considered for flyovers, interchanges, elevated corridors and skyways, the civic body wishes for trial bore of different depths to generate detailed analysis for soil and rock samples at different depth intervals. This is to result in recommendations for suitable foundations for the project components such as flyover and elevated corridors. Also, for classification and to design transmission line towers rationally, geo-technical investigations are to be taken up at specified tower locations for inputs on substrata profile and relevant soil and rock parameters at the given site.
The GHMC is also keen on the appointed consultants obtaining information and reviewing existing local knowledge on streams in the neighbourhood, water resources, abandoned underground works, quarries located close by, wells that are unlined, landslides and recent land fills.
Recently, the Chief Minister, K. Chandrasekhar Rao asked for strategic road development of eight corridors in the city including Uppal-Sangeet Junction, Gachibowli-JNTU junction, Tank Bund-Afzalgunj, Abids-Chaderghat via Koti, Habsiguda-Mallapur, Hayathnagar-Nalgonda Crossroads, Chaderghat-Putlibowli-Jambagh-Nampally and Puranapul-Aramgarh.
