The structurally intrusive investigations will be undertaken to obtain information on the geometry, physical properties, performance and condition of masonry elements, reinforced concrete structures, precast concrete elements, core and material (dust) sampling and testing, brick/stone and paint specimens; the presence of hidden voids; the geometry, physical properties and condition of steel and iron elements, timber elements, 19th century ceilings and raised floors; the condition of flat roofs, buildups and materials for room finishes; services distribution routes; the Contractor will undertake NDT, coring, radar scanning, GRP and GRS. These surveys will provide data on the structure of the building, compartmentation and the loading of floors. Intrusive structural surveys will also be undertaken to determine the physical property and condition of boundary and internal fencing including foundations. Intrusive surveys will be undertaken to establish properties and conditions of hatches, ceiling types, hidden voids, chimney pieces, fire places, cast iron and cast iron protection surrounds; fixings, glazing and weatherings of windows. The Contractor may also be required to undertake a survey of the façade; curtain walling, external doors, lead spandrel panels, insulated glazing units, brise soleils, balustrade and guardrails, entrance canopy, roof plant enclosures, louvres; fire compartmentation; junction of the slab edge with the external wall / façade, junction of the floor slab with any protected shaft / riser, life shafts, fire stopping of any openings in the floor slab, integrity of the protected staircase, integrity of protected shaft / risers and fire stopping of any service penetrations, integrity of protected lobbies to staircases and lifts, fire door condition survey, integrity of compartment walls and fire stopping of service penetrations, provision and condition of cavity barriers in concealed voids including ceiling and floor voids, investigation of basement natural smoke vent. The Contractor will undertake similar intrusive structural surveys in other locations outside the Palace of Westminster, including but not limited to the QEII conference centre. Surveys will also include waterproofing and movement joint surveying, minor external excavations below ground level; core and material (dust) sampling and testing; lead paint survey; hanger casing removal and testing; fire hydrants and routes surveys.

The Contractor will minimize any disruption or disturbance to the protected historic fabric, or personnel working within the Palace of Westminster; will limit the requirements for on-site interventions; provide a flexible approach to reconfiguration / adjustment; minimize the project's environmental impact; acquire, store and present data utilising secure data transmission protocols and methodologies; allow for adoption by parties in the future. The Contractor will provide instrumentation and monitoring in other locations, including the QEII conference centre, to establish a baseline for future construction activities. The Contractor should be able to propose monitoring configurations that can be adapted if the structure is covered by a scaffold during the monitoring period. The Contractor will install the instrumentation using fixings and brackets, with bespoke design if required, which are fully removable causing minimal damage to the ashlar stonework façades. The Contractor shall provide a software platform for the Delivery Authority to plot and view the monitoring data on a continuous basis. The Contractor will ensure that the methodologies for installation, maintenance an decommissioning follow the hierarchy of controls in the Working at Height Regulations.
