Excavating the Holy Grail, a new north, and the ceiling-mounted loo: 1 April’s top stories

The new 5D Ground Intelligence system (with Archaeo Assist) from Xwatch is being used by archaeologists trained to use excavators. The system extends machine safety beyond traditional height, slew and rated capacity indicator controls to real-time subsurface awareness.

Using onboard sensing combined with telematics, the system monitors ground interaction during excavation, logging and geo-tagging detections in real time. Operators receive live in-cab alerts when metallic objects, utilities or unknown obstructions are identified, with one early detection reportedly classified as a possible ceremonial object with a secondary classification of cup.

Where items of potential interest are detected, the Archaeo Assist function generates a predictive reconstruction of the object or feature, including estimated age, origin and cultural relevance, based on available data.

And from the Holy Grail to the Silver Bullet: Rich Draper, head of estates digital at the University of Oxford and co-chair of BIM4Estates, has launched EstateOS: The Silver Bullet. He describes it as the ultimate all-in-one estates management system. It fully integrates every dataset, predicts maintenance issues before they happen and takes just 24 hours to implement. The annual subscription is an almost unbelievable £9.99 for an unlimited number of users.

Meanwhile, in a move likely to cause widespread chaos, Ordnance Survey (OS) is trialling Adaptive Grid North – a rotation of Grid North on OS maps. This will “boldly future-proof and simplify navigation for generations to come,” according to OS. Dr Polly Axis, senior orientation specialist at OS, explained: “Our long‑range modelling indicates that aligning magnetic north with Grid North through a proactive macro‑rotational intervention could reduce theoretical navigational ambiguity by up to 0.00003%. The reassurance explorers gain from knowing their map is ‘pointing in the right direction’ for the next century should not be underestimated.”

Generating slightly less confusion than OS, the Offsite Alliance has renamed itself the Onsite Alliance, reflecting that ‘offsite’ is “just construction that happens onsite… somewhere else”.
