HATO Drainage and Roof Replacement

Harris Academy Tottenham is an academy school providing education for pupils between Reception and Sixth Form. The existing above ground rainwater drainage at HATO is routed internal to the building envelope, and encased within the main columns. This drainage has been subject to severe defects throughout the building. In addition to the poor state of the rainwater goods, the profiled steel roof sheets are approaching 30 years old and are showing signs of their age.

The current proposal is for a new roof to be installed with new accompanying rainwater goods being designed and constructed external to the building. An access system for maintenance will be built into the design to enable the school to maintain the system going forward. The size of the roof to be replaced is ~3500m2.

The school is fully occupied with no spare teaching space and limited external play space. It is currently proposed that all works be undertaken during holiday periods, with limited works undertaken during term time.

This scheme is best suited to SMEs and roofing specialists with a demonstrated ability to undertake schemes within live environments, notably within the education sector.

The Contractor will be responsible for developing, agreeing and finalising the design following CEMs. Contractors will be required to: - Undertake D&B of new roofing system - Undertake D&B of above ground drainage and below ground drainage connections - Lead the scheme through planning applications and approvals from Local Authorities (Thames Water, Haringey Council Local Planning Authority etc.) - Manage temporary/enabling works within an operational school - Have a demonstrated capability of replacing roofs within operational environments - Have a demonstrated history of managing HS&W - Have a demonstrated capability for managing client expectations and meeting deadlines

The works will be contracted out via a single stage D&B contract. An appropriate Principal Contractor will be appointed under a PCSA to develop the design, manage any planning applications and inform a fixed price for the works. The scheme is to use JCT Design and Build Contract 2016 Edition with PCSA.

Responses to the ITT will be judged against the evaluation criteria set out within the ITT documentation. The contract will be awarded on the basis of a Qualitative 60% & Quantitative assessment 40%. Should a bid score less than 40% for Quality, this will be grounds for exclusion.

The target programme is to have all works concluded by the start of Sept 2023. Contractors are to develop their programmes to undertake the works within holiday shut down periods.

A completed PQQ (attached) is to be emailed to Chris Bullough from all those interested in the scheme by no later than 14th May 2021.
