23 Page 2, Para 1.3 The GC will prepare Technical Specifications for thevehicles for both the Corridors and will scrutinise thedesign / drawing submissions of the successful Tendererfor the vehicles and clear the designs after taking approvalof BMRCL. The GC will supervise the designdevelopment of the vehicles and their various systems,through a process of design submissions, and a welldocumenteddesign approval process acceptable toBMRCL. The ……………..PQ Questionnaire.4 Page 3, Para 1.8 The coaches should be modern, lightweight, made ofstainless steel or aluminium with 3 phase AC drive havingVVVF control, regenerative braking, and modern controldevices such as ATP, ATC, etc. Coach bogies should be ofproven design and modern technology. The coaches shallbe required to operate at 750V d.c. Third Rail system onSTANDARD GAUGE (1435 mm).5 Page 5, Para 3.3 The safety worthiness of the rolling stock to be procuredwill be evaluated by an independent agency and sanctionof competent authority will have to be obtained. Safetyworthiness would be to ensure that the various componentsof the rolling stock are within the prescribed limits ofstress, temperature rise etc. and also to ascertain theoscillation behaviour of the rolling stock. Detailed design,calculations and “oscillation trials” will be done in thisconnection.The contractor should be in a position to provide necessarysupport (have experts with adequate qualification,knowledge and experience) to assist BMRCL for effectiveinteraction with concerned authorities.The GC will prepare Technical Specifications for thevehicles for both the Corridors and will scrutinise thedesign / drawing submissions of the successful Tendererfor the vehicles and clear the designs after taking approvalof BMRCL.
