The tilt sensors, based on well-established MEMS technology, are mounted within a rugged, heavy-duty waterproof die-cast metal enclosure suitable for the harsh environments found within construction and building industries.
Thermal effects of the MEMS sensor is minimal but in order to compensate for the effects of temperature on the enclosure, mountings and structure, the unit is fitted with an integral thermistor.
The digital RS-485 output signal provides the ultimate in accuracy together with the advantage of being able to create a digital BUS system where all sensors can be linked together and cable qantities significantly reduced.
Each unit is individually calibrated to provide the ultimate in system accuracy and repeatability.
The Pinnacle, also known as The Bishopsgate Tower, is a 288m, 63-storey skyscraper under construction in the City of London.
When completed (pencilled in for 2013), the building will reach 288m, making it the tallest in the Square Mile and second only to the Shard in stature.
Standing on the deepest piles in the whole of London that are 65.5 metres deep, the building will be clad in ventilated glazing that works like a snakeskin with every single piece of identical size reducing build cost.
The inside of the spiral at the top of the building will contain PV panelling to generate power from the sun.
Demolition of the site began in mid-2007 and was completed the following year.
Geosense instrumentation was used in the monitoring of existing basement walls during demolition of the internal basement slabs (3 levels). The existing basement walls were to be retained for the new structure, however not enough information was available on their present condition, therefore extensive monitoring of the walls was proposed.
Bishopsgate Tower Case Study
The project involved the construction of a high quality, 11-storey, 584-bed hotel in the City of London, adjacent to Fenchurch Street Station and close to existing rail tracks and Walsingham House.
Facilities of the hotel include reception, café, restaurant and bar at ground level; meeting rooms on the first floor; and further meeting rooms and bar at rooftop level where there is a glazed ‘Skylounge’ offering views over the Tower of London and the city’s financial district.
