Sectional elevation of the typical elevated viaduct drawing enclosed with the tender/bid documents shall be referred for the same. The Contractor shall verify the Road level/Ground level provided in the GAD with the actual levels at Site.
  • 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. Some spans will have to be designed to accommodate the crossover’s with Deck continuity. (Approximate locations if any are shown in the GAD for reference).

Superstructure spans to be constructed by segmental construction methods. It may be noted that alignment may contain certain special spans. No extra shall be paid for the construction of these spans.

Alignment is crossing Mother Teresa Flyover, Bhakti Shakti chowk (GAD may be referred) also the Alignment is passing along the Bhagwan Mahavir chowk, Chhatrapati Shivaji Maharaj chowk, Khandoba chowk, New proposed PCMC pedestrian pathway and Nigdi Flyover, where there are necessity of Obligatory Spans.

Bidder is requested to quote the price against lump sum Schedule considering the necessary/requisite arrangement as per the site conditions. Nothing extra shall be paid in the construction of foundation, substructure and superstructure of the obligatory spans.

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 Maha Metro. 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 locations 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 Maha Metro. 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 (Crossover’s) I – Girder with deck slab may be 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-Girders may be resorted to with Maha Metro’s approval 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. However, in case of any unforeseen circumstances resulting in change of rail level, variation in the range of ±500mm from rail level provided in the GAD enclosed with the bid/tender drawings is deemed to be included in the lump sum portion of 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 Maha Metro.
