Water Mist Suppression contract

Descriptions

Transport for London (TfL) will be issuing a MSQ for the Design and Installation of Non-compliant Water Mist Systems and Existing Sprinkler Systems on 24 London Underground (LU) sites The primary focus of the MSQ is to obtain market feedback and better understand the supplier market appetite and trend, capability and capacity, as well as perceived risks and how to mitigate these as well as any opportunities. The results from the finds of the MSQ will be analysed and compiled into a market sounding report and used to help shape the Water Mist Systems procurement strategy. The purpose of the contract is for the Replacement of Water Mist Suppression Systems currently installed in thirty-four (34) locations situated within twenty-two (22) different London Underground stations whilst ensuring value for money. The water mist systems have been installed on the TfL infrastructure in the early 1990's following the publication of the Fire Precautions Sub-surface Railway Regulations 1989 (updated 2009). The systems were installed where conventional sprinkler systems were not considered viable due to practical or logistical constraints and designed, installed and maintained in compliance with the American Standard NFPA750. Due to the increasing number, sizes, type of storage and trading activities within the network, further review of risks and tests for these suppression protection systems were undertaken and evaluated. This confirmed a requirement to replace these systems and design modern, compliant equivalent water mist system to replace the ageing non-compliant systems currently installed in the TfL LU estate. The modern systems will be tested by TfL to BS EN 14972-1 Annex A with a deluge time of not less than 60 minutes from the appropriate number of cylinders located locally, to provide reliable fire suppression to specific rooms identified. In the main this new installation will be designed for but not limited to Cleaner's Stores, Bin Stores, Stores and Tenancies.
