Scope of Works:

Design and Construction of elevated Metro Viaduct including viaduct in station portion from Chainages (-)7577.056m to (-)13457.046m in Reach 2b of Nagpur Metro Rail Project Phase II. The total length of the viaduct is 5879.99 metres. GAD enclosed with the bid/tender documents may be referred. Salient details of GAD are given below:

  • The elevated Section of (Reach-2B) starts from Chainage (-)7577.056m and ends at (-)13457.046m. However, Pier and Pier Cap at the beginning of the section will not be a part of scope of works defined in this contract.
  • The Design and Build Contractor has to design the Viaduct ensuring a minimum statutory vertical clearance of 5.5 metres to the Metro structure above the existing road level. Sectional elevation of the typical elevated viaduct drawing enclosed with the tender/bid documents shall be referred for the same.
  • Whole length of the viaduct has to be designed for double line standard gauge track as shown in the GAD. System is planned with end evacuation and 25 KV AC OHE traction. The tenderer/bidder will have to use a Segmental Box girder integrated with the parapet (Segmental box girder is Maha-Metro’s preferred choice).
  • Some spans will have to be designed to accommodate the emergency track crossover, special track layouts (e.g. pocket track) (Approximate locations if any are shown in the GAD for reference).

For Viaduct:

Detailed Survey of the alignment for viaduct (including station locations), soil investigation at every pier location, utility checking, fixing an optimised span configuration as per contractor’s design subject to the obligatory requirements as shown in the GAD.

Design & Construction of Open/Raft/Footing/Pile foundations including pile cap, pier, portal pier (wherever applicable), pier protection crash barrier, pier cap (normal, cantilever, extended as applicable), portal beam, bearing pedestals, bearings, shear keys, seismic restrainers, hold down devices if required etc. complete.

Design & Construction of Pile foundations including pile cap, pier, pier cap, pier arm (platform level/track level), superstructure (same as that followed in viaduct), bearing pedestals, bearings, shear keys, seismic restrainers (if required), hold down devices if required etc. complete in the station limits along the viaduct portion.

A typical Elevation Drawing at station locations is enclosed with the tender/bid documents. The span configuration may vary slightly based on site constraints. Typical elevated station shall have pier arms only at track/platform level (Except Cantonment and dragon palace station as Cantonment Station is having portal pier arrangement in the station’s central viaduct portion and dragon palace station is having pier arm at both concourse and platform level). 

The pier arms shall be RCC/PSC members as shown in the tender drawings. These pier arms shall accommodate the platform level girders with deck slab (platform including circulating area, station roof, connecting bridges with roof, etc.) and other subsequent finishes. The platform level girders with deck slab and the subsequent finishing is not included in the scope of works under this contract.

Hence, does not constitute a part of the Lump Sum contract. The arrangement of central viaduct portion cantonment station may be referred to as per attached drawings. Kanhan Metro Station is having off road station construction and the arrangement shown for central viaduct portion in the attached drawing may be referred and the same is in scope of contractor.

Design & Construction of superstructure of standard spans, non-standard spans/(obligatory) spans, spans supporting special track layouts if required. Superstructure spans to be constructed by segmental construction methods. (Segmental box girder is Maha Metro’s preferred choice).

However, contractors can propose alternate sections keeping the overall dimension of the superstructure as indicated in the tender drawing. It may be noted that alignment may contain certain special spans. Nothing extra shall be paid for the complexities involved in the construction of these special spans.

Alignment is crossing Nallah and portal piers are to be provided at few locations and the same is included in the scope of works under this contract and nothing extra shall be paid for the complexities involved in the construction of these spans.

Alignment is having one 48m steel girder approach span to Cantonment Station as shown in the attached GAD at Chainage Ch. (-) 8665.346 to Ch. (-) 8713.346 m is included in the scope of works under this contract and nothing extra shall be paid for the complexities involved in the construction.

GAD furnished to the contractor as a part of the tender/bid documents contains tentative span configuration proposed by the Employer. However, the contractor shall put forward his proposed span configuration. Engineers shall review and approve the same in consultation with Employer. Indicative spans are 19m, 22m, 25m, 28m, 31m.

Standard span configuration of 28m or 31m shall be adopted where the alignment is either straight or radius of horizontal curvature is 700m and above Suitable span configuration of 19m, 22m, 25m shall be adopted if the radius of horizontal curvature in alignment is sharper than 700m. At obligatory locations or where there are site constraints, the span length can be 34m.

Segmental box girder construction for a span length beyond 34m shall be permitted only in exceptional cases by the Engineer duly in consultation with Employer. If the radius of horizontal curvature in the alignment is 150 m or sharper, then top width of deck slab in superstructure of viaduct shall be ensured as per the guidelines issued with tender documents at Appendix 20.

For spans supporting special track layout if any (e.g.: pocket track, elevated stabling lines) PSC I-Girder with deck slab may be permitted at no extra cost. Steel Spans/Steel Columns/Steel Piers are not permitted. Indicative spans may be followed for standard units as far as possible. However, in case of obligatory span and sharper curves, Steel Composite I-Girder may be resorted to, with Employer’s permission at no extra cost.

Bidders have to make sure that while submitting their proposal and superstructure design, the rail levels as envisaged in GAD shall be final. Variation in the range of ±200mm from rail level provided in the GAD enclosed with the bid/tender drawings is deemed to be included in the lump sum portion of the contract.

Variation beyond this range shall be paid or deducted as the case may be. Only the increase/decrease in height of pier(s) (i.e. concrete and steel quantity) will be considered for either payment or rebate in this case. Difference between actual executed Rail levels and Rail levels as furnished in the GAD at each Pier location shall be considered to evaluate any variation arising on account of change in Rail level.

  • Purely Steel Structures shall not be allowed. However, in obligatory locations, composite structures may be permitted with prior approval of the employer.
  • GAD enclosed with this RFP shall also contain the tentative span configuration. Contractor is permitted to make amends to the span configuration based on site constraints or utilities subject to the approval of the Engineer.
