The Hale Wharf scheme is being delivered by Waterside Places – a strategic joint venture between Canal & River Trust and Muse Developments, in partnership with the Mayor of London and London Borough of Haringey.
Lock 17 has been designated as one of the Mayor of London’s Housing Zones, meaning the site will make an important contribution to the Mayor’s and the Council’s aspiration for 2,000 new homes in Tottenham Hale.
Key points
Value Engineering
During the tender period it was evident that the external wall design had been over designed and, as a result, it was not meeting the client’s target budget.
Applying our collective technical knowledge in façade engineering our team worked in collaboration with the client’s consultants and manufacturers to develop and procure a revised design. This included reworking the thermal performance to meet the energy model more efficiently and reduce cost and added significant improvements to the building envelope and removed combustible materials with minimal impact to programme and budget. Agreement with the client to extend the scope of works was required, e.g. including preliminary piling works.
This offered an additional benefit of reducing the overall programme with minimal impact to programme and budget.
Programme Management
To minimise negative impacts on residents and local stakeholders, programme management was critical throughout the scheme.
We therefore decided to base a planner on site in Haringey. They supported the team by establishing master programme and milestone targets, as well as providing fully detailed programmes to establish critical paths. Progress recording and monitoring was undertaken on a weekly basis, giving up to date status of the project in terms of design, procurement and construction.
This also enabled accurate decant programmes and up to date advice throughout delivery and ensured safe routes and parking, clean infrastructure and mitigation of nuisances.
Quality Assurance
During the delivery of Lock 17, Snag-R was developed from a-snagging based software and advanced into a tool to capture quality information and data relating to the project’s key inspections, this information formed part of the projects ‘Golden Thread’ of information and operational information.
The main challenges were implementing a change in culture with the users of the software, changing and implementing the analytical algorithms to suit site inspections and ensuring the records were maintained during the project’s construction.
The team overcome these challenges using methods such as materials installation/compliance with manufacturers specification; quality hold points; digital thread; and collaboration.
Design Management
McLaren was appointed on a PCSA with RIBA Stage 4 design requirements. Led by our Design team, we reviewed the design information, identifying gaps and making amendments to update the design in line with emerging building safety regulation. We collaborated with the manufacturer to develop a solution and offered contractor’s proposals of materials and products to enable the RIBA Stage 5 design to be completed.
Building Safety
All products/materials selected were Building Regulations compliant demonstrated by collecting data sheets and recording the performance of the products in tested fire conditions. This information was submitted to the fire engineer, Building Control and the building’s insurer for their approval in accordance with Building Regulations ahead of installation.
Fundamental to our approach was the introduction of a quality test and inspection regime, linked to the electronic system. This guided the team through a structured approach to inspecting, recording and signing off key hold points on the installation to verify critical fire safety installations.
