HS2 N1/N2 - Noise Insulation

Tender description

BBV JV is seeking to appoint a specialist glazing contractor to support its obligations to provide noise insulation at eligible properties and to protect occupants from the effects of construction noise and the operational railway. The Environmental Statement identifies 295 eligible properties for noise insulation. BBV JV is currently reviewing the construction and operational assessments to determine whether any additional quantities of noise insulation will be required. This information will be available by the time the ITT is issued for this opportunity. The package will be competitively tendered and assessed against a split between commercial (price) and non-commercial/technical criteria. Balfour Beatty VINCI (BBV) is a long established Joint Venture between two global leaders in the delivery of critical infrastructure and highways projects. Following the decision to proceed with HS2 earlier this year, the BBV Joint Venture can now commence full detailed design and construction of the HS2 N1/N2 railway. The scope of works will comprise: • Support BBV JV in engaging with the owners and occupants of eligible properties to arrange access for surveys; • Carry out surveys to inform designs and requirements of the noise insulation package for eligible windows on eligible facades; • Design and production of the noise insulation package; and • Installation of the noise insulation package on the eligible facades. The Noise Insulation Package comprises: • secondary glazing for eligible windows on eligible facades, plus supplementary ventilation if required; • blinds on facades where there is a need to control solar gain; and • insulation treatment for external doors on eligible facades. As well as providing services to support the advance installation of noise insulation to eligible dwellings, the contractor will also be required to support BBV JV in the surveying, design, installation and commissioning of noise insulation to any special case properties identified both before and during the construction works, as necessary.
