1516-897 – Boiler replacement and other mechanical works at two primary schools in Islington

Islington Council invites suitable expressions of interest from suppliers for boiler replacement at Highbury Quadrant Primary School; and for boiler and hot water storage tanks replacement and National Grid district heating connections at Montem Primary School, Hornsey Road.

Current status / Background

Islington Council’s Children’s Services has prioritised existing school heating plant which requires replacement. This is reflected in condition reports for the two schools. The heating system plant at Highbury Quadrant Primary School contains existing commercial gas boilers installed approximately 20 years ago and at the end of their usable life. The commercial gas boilers at Montem Primary School were also installed approximately 20 years ago and are at the end of their usable life. Annual servicing and maintenance has highlighted obsolete serviceable parts which means that future boiler maintenance tasks will be expensive and/or involve prolonged boiler plant down-time.

In addition, the National Grid is developing a site adjacent to Montem Primary School to upgrade its infrastructure, including a major electrical sub-station. As part of the Section 106 works the National Grid is providing a district heating system which will include Montem Primary School. The works required here will also include creating an interface between the district heating system and Montem Primary School heating system.

The requirement

Islington Council requires the replacement of existing boilers at Highbury Quadrant Primary School and the replacement of existing boilers, hot water storage tanks and connection of National Grid District Heating System at Montem Primary School. The new works will include:

More efficient boilers

More efficient hot water storage tanks

More efficient heating controls

Connection of National Grid district heating system

School boiler replacement/upgrade works are best conducted outside the heating season and within periods of prolonged school non-operational times. The task involves works in a small boiler room space, therefore limiting the number of operatives at the same time. The successful contractor shall be ready to mobilise resources from 7 - 21 July 2016 with the commencement of works 21 July and the completion of works no later than 24 October 2016; although return visits to Montem Primary School are required for seasonal re-commissioning of the district heating system: April 2017, July 2017, October 2017 and January 2018.
