This procurement process pertains to the services industry category and requires suppliers capable of providing the necessary equipment, labour, and supervision. The tender, which was published on 13th March 2026, is currently in the active stage with a deadline for submissions set on 27th March 2026. The contract is scheduled to commence on 15th November 2026 and conclude on 9th December 2030, covering regions including the United Kingdom, British Oversea Territories, Channel Islands, Isle of Man, and other global locations. This tender offers significant opportunities for companies experienced in geophysical surveys and instrumentation related to surface observing and tension measuring. Businesses with expertise in MASW and CSW methods, or those specialising in the analysis and interpretation of seismic data, could benefit greatly from this procurement opportunity. The project offers considerable value, with an estimated service contract worth up to £2,500,000. Although the opportunity is not aimed at SMEs or VCSEs, it provides substantial growth potential for firms that can deliver comprehensive testing solutions and report on subcontractor management effectively. ## Notice 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.
