Enhancing passenger experience through design

and planning

Focus One:

SCOPE OF OPTIMISATION OF LIGHT FITINGS & AIR CONDITIONING

• Lighting of Metro stations are generally overdesigned and fittings at many locations are kept in switched off condition and this results into passengers’ discomfort and dissatisfaction.

• To address the issue RVNL has taken few measures.

• RVNL is using 3D Lighting Software (DIALUX EVO – 5.2 latest model) to finalise the position, angle, location of the fittings for desired lux level.

• RVNL is selecting the colour of wall, roof, floor, granite etc to have largest possible light reflection factor through this software.

• LED Lights are being provided in Metro stations.• All the LED fitting shall be with intelligence so

that dimming can be done whenever or wherever required. All the required fittings shall be occupancy sensored.

• SOFTWARE (DACCS-HKGSG) is being used for AC tonnage calculation which takes into account of thickness of floor, roof even the presence of main beam, cross beam, pillar etc under the roof to have real time heat load to AC.

• REVIT Architectural Software

3D Model for lighting software (Dialux EVO- 5.2) used for Joka Metro Corridor: optimization of angle, numbers and selection of material

Incorporation of real wall mural being simulated to consider real time reflection factor at a station

Positioning and angling of individual light fittings is decided by using this software - at Joka station

Traction Sub Station/Auxiliary sub station Lighting design has been made after incorporating the equipments in the proposed layout in the said software

Passage for passengers and selection of the building material and color is also simulated and decided using this software.

Optimizing planning and project management

Focus Two:

Never implement a project unless all major resources are available.

Motivation to the complete team.

New approaches and latest technology to help build in challenging environments

Focus Three:

An Engineering challenge was confronted due to the presence of seven EHV and 13 HV overhead lines in the approach of Joka Depot

132 KV Cable termination on narrow base tower erected on Canal itself.

Conventional (Optimal) Gantry System requiring acquisition of Land

JOKA MODEL

This model resulted into a saving of Rs 50 Cr.

• Existing system of 33 KV/11 KV/750 v DC replaced by 33 KV/750 V DC for removing requirement Receiving Sub station (RSS) with a cost saving of Rs 300 Cr for 62 Kms planned.

• Existing system of steel third rail is replaced with Aluminum third rail for energy saving by reducing resistive loss.

POWER SYSTEM

Adoption of new technologies for Metro Rail Built

Focus Four:

Design of Earth mat

IS 2309 not applicableIEC 62305 applicable

All the Metro Stations have been provided with the Lightning Protection as per IS:2309-1989, which is not only old but does not provide adequate safety. RVNL shall be first one to implement safety as per IEC:62305.

The empirical formula as IEEE Standard-80 & IS 2309 is applicable only when the earth mat is symmetrical which is not possible in a typical elevated Metro station.

Earth Mat designed for Joka Metro Station as per IEEE Standard-80, simulated by using E-TAP Software.

RVNL is perhaps the only Metro Builder in India who has used E-TAP Software for calculations of Step Voltage, Touch Voltage and Grid Voltage for earth mat. Our design does not use abnormally thick concrete slab to compensate the inadequacy in using the standard formula which have a limitation. Our design is not only technically correct, it is the most economical and optimal design.

Others

Remote Eye Monitoring System in RVNL is one such initiative.
