Scope of Work:
- The scope of work involves “Ground improvement work involving supply & installation of Pre-fabricated vertical drain (PVD) & other allied works as per approved design from DFC Km 145+524 (IR 112+716) to DFC Km 151+000 (IR 118+360) excluding Stilt Bridge stretches between DFC Km 145+524 and DFC Km 150+530 in connection with construction of Western Dedicated Freight Corridor Phase II Vaitarna Sachin Section- Infra Works Package SS2A in Maharashtra State”.
- The site is located on Eastern side of the Indian Railway track and generally well approachable during the fair weather season for doing the work. The contractor must carefully make their detailed planning so as to ensure uninterrupted working during the monsoon season also.
The broad scope of the work covers:-
- The specification covers the material and constructional requirement using Prefabricated vertical drains (PVD). The extent of work shall be shown on drawing and described in technical specifications. Supplementary requirements of modification to his specification shall be defined in the drawing as per instruction of the Engineer/Employer. The work shall be carried out as per designed in phased manner as directed by the Engineer/Employer in connection with WDFC CTP-12 Project. The work site is located/ proposed at mentioned Chainage along the alignment of Vaitarana- Sachin section of WDFC CTP-12 project.
- The basic design principle for the use of PVD is consolidation/settlement in the natural ground. In absence of PVD, the soil pore water follows the flow path only in vertical direction i.e. one-dimensional consolidation. However, with the use of PVD, pore water in the clay sub- stratum flows horizontally (radially) as well as vertically i.e, three- dimensional consolidation. The consolidation process starts on application of Pre- load (the expected load applied in advance) after the installation of Prefabricated Vertical (band drains). Conventionally the preload is applied by way of the temporary/ permanent embankment over the treatment area. However, due to the lack of the available time, a new method of pre- loading using vacuum loading is proposed. The vacuum loading is the application of the external negative pressure to the soil surface, in the form of vacuum. A higher effective stress is achieved by the negative pore pressure. Each PVD will be connected to the vacuum channel using the tubing systems and drain connectors, piezometers’ and Settlement Markers shall be installed to check the efficacy of the proposed system as per requirements. Construction of drains (if required) along the alignment within ROW as per drawings.
- The work consists of ground improvement using prefabricated vertical drains (PVD) of band drains of specified quality in conjunction with vacuum consolidation up to depth required to stabilize the railway embankment which requires to be constructed over very soft compressible clay. The work is to be carried out in marshy conditions some parts of which may be water- logged. The clay subsoil is very weak and highly compressible and requires to be improved to increase its shear strength as well as to minimize or eliminate post- construction settlement. The CONTRACTOR is well advised to visit the site before making the offer.
