A Mobile Elevating Work Platform (MEWP) was brought on to site for a week to allow for some up-close inspections of the higher-level facades of both the North and South Porticos. The MEWP took the team to over 20 meters high!

During the week the architects from DIA, surveyors from GBG conducted Ground Penetrating Radar (GPR) surveys and stone condition surveys. GPR is a non-invasive geophysical method that uses radar pulses to image subsurface. GPR was used to identify embedded metalwork, fabric construction and locations/routes of embedded downpipe, allowing for the identification of potential conflicts enabling effective planning.

Researchers from our Oxford University Heritage Innovation partnership team also took the opportunity to preliminary survey the stone types to give us an understanding of which quarries/beds the various stones have come from.
