The contractor is seeking a Supplier to undertake the detailed design based on the drawings provided by the designer, manufacture, storage (if necessary) and transport to the different locations Routewide of the access staircase that will be used to access the different embankments and structures along the Sublots. The subcontractor is to provide all necessary permanent design information, materials and equipment to construct the staircases across the project. This advert is to engage the market for a potential of 1 of 3 avenues; 1) Glass Reinforced Plastic (GRP) 2) Precast 3) Cast-in-situ Additional information: 1 of 3 options to be chosen, not all 3

This requirement is related to the construction of piles for the HS2 Phase 1 Main Works Civils Contracts. These works are integral to the structural stability of noise barriers and other infrastructure elements, ensuring compliance with HS2's engineering and environmental standards. Key aspects of this package include: > Collaborative review of Contractor designs to incorporate constructability considerations. > Provision of labour, materials, and equipment required for piling construction. > Implementation of quality assurance measures and adherence to technical specifications. > Coordination with other sub-lot activities to ensure seamless integration and progress. The package is segmented by geographical sub-lots (N1 and N2), with detailed requirements provided for each location in accordance with site-specific constraints. Additional information: -

The supplier of this package should be able to service, transport and maintain Tower Lights.

BBV has developed its delivery strategy around several sub-lots across the Area North route, which encompasses both Sectors N1 and N2. We require a Contractor who can offer a comprehensive 24 hour available emergency spill response. Including containment, collection and clearance of all contaminated materials, both hazardous and non hazardous spills. Additionally, an electronic waste management system is required to support our delivery strategy. The complex nature of Area North in terms of geography, scope and scale has informed our packaging strategy for these works. We have divided Area North into 6 distinct geographical packages which align with sub-lot delivery strategies and approximately 86 compounds (subject to change) plus operational works areas requiring emergency response services Additional information: N/A

The contractor will provide BBV with Gritting services, Salt grit box replenishment & snow clearance. We require the contractor to visit various locations covering Area North, at agreed trigger temperatures, provide services to mapped roads as required. The provider needs to be able to offer a comprehensive 24-hour available emergency gritting services.

A review of video conferencing (VC) equipment currently deployed across BBV office locations has identified that several units are approaching the end of their manufacturer support lifecycle. To ensure ongoing operational effectiveness and maintain compliance with BBV's technology standards, a replacement programme is required. The following devices have been selected as the approved replacement models: Poly Studio Video Bar X52 Poly TC10 Touch Screen Tablet

Noise barrier consumables include all small components required for the installation and fixing of the noise barrier system along the project alignment. These items typically include bolts, nuts, washers, nord locks, joint materials such as EPDM strips used during installation. Their purpose is to ensure the correct assembly, alignment, and secure fixing of the precast acoustic panels and associated elements to the supporting structure. These consumables are essential to achieve the required structural stability, durability, and acoustic performance of the noise barrier system.

BBV intends to appoint their preferred bidders on the basis that risks are owned by those best able to manage the risk. Successful tenderers will be required to provide the equipment, labour and supervision to carry out the measurement of the shear waves velocity and ensure delivery of their package of works with the interpretation of the results via a report included. Each offer is required to identify the areas where shared responsibility or a change in responsibility would offer value to the project. Rates to include reports, staff, preliminary visits, site inductions, testing, equipment's, calibration of equipment to enable contractor to carry out the measure of the shear waves velocity. The measure of shear waves velocity would be happening during the hold period on the weather protection layer to limit the interaction with other parties and affect the collection of data. The depth of measuring should be up to 7m depth and on 1 lane of measurement. All reports are to be supplied in an agreed format, such as PDF/Word/Excel. Any agreed format and colours mapping is not to be changed without agreement. Reports are to be emailed to agreed email addresses within 2 weeks after completion of the site measures. Where client specification is supplied this is to be included on report. No external agencies can be subcontracted to without the approval from BBV. Method of testing Two (2) method of testing might be proposed in the tender, but it should be clearly defined. The tenderer should justify of using this method previously and provide suitable references. MASW method (Multichannel Analysis of Surface Waves) The geophysical survey used MASW to generate and record surface wave energy. The recorded energy was analysed to produce modelled S-wave velocity profiles. The MASW method relies on surface wave seismic energy (specifically Rayleigh waves) which can be generated by an active source (usually an impact event). The propagating surface wave energy was recorded with a linear array of geophones. The captured dataset from a single source event is referred to as a 'shot gather.' The shot gathers are analysed to measure the Rayleigh wave 'dispersion' (velocity as a function of frequency). Dispersion of Rayleigh waves occurs because their depth penetration is dependent on wavelength. Higher frequency (shorter wavelength) Rayleigh waves will typically propagate at a relatively low velocity, representing shallow materials, while lower frequency (longer wavelength) Rayleigh waves will typically propagate at a higher velocity, representing deeper materials. CSW method (Continuous surfaces Wave) The CSW testing system uses a vibrating source with an operating range of 5 to 100 Hz to produce surface or Rayleigh waves that propagate across the ground. These waves are detected by a system of geophones and analysed using software to provide a stiffness versus depth profile. If required, office-based post-processing can provide

The provision of technical Soil Scientist support, both on site and via desktop delivery, for the delivery of soil surveys and assessments, reinstatement plans and post reinstatement surveys and advice on soil handling, management and reconditioning requirements.
