Structural Monitoring, automated monitoring, tilt sensor monitoring, environmental monitoring

MK Surveys were approached to provide a suitable structural monitoring solution at a site in central London where a challenging project involved the demolition of a number of terraced buildings whilst retaining the listed façades and maintaining the party walls.

Following careful consideration and a thorough client consultation process the chosen monitoring solution utilised 54 dual axis tilt sensors installed onto the façades and party walls. The sensors were set up to communicate with an on-site datacentre which was able to transmit the data to the cloud to be retrieved by our local servers. The data, recorded at 15 minute intervals 24/7 was managed, analysed and re-formatted to a clear concise format for weekly reporting to the client. ‘Traffic light’ alert systems were also setup to notify relevant personnel via email if any readings were out of a specified tolerance.

A settlement monitoring solution was also established to complement the data recorded by the tilt sensors and provide movement readings on the Z axis. Monitoring rivets and bar coded strips were installed onto the structures prior to any demolition works. Readings were recorded at regular intervals, using a precise level instrument and then tabulated before being communicated to the client.

MK Surveys were commissioned to assist with a sensitive vibration monitoring project where a new development was under construction within close proximity to a power station. The construction involved pilling, causing significant vibration which was predicted to endanger the assets of the power station nearby.

The monitoring solution utilised on site involved five vibration sensors with designated data loggers, mounted on the concrete bases of the assets adjacent to site. The data loggers were able to be communicated with from our head office using a modem to dial in and retrieve the data.

The data, continuously recorded throughout the working day, was downloaded at 30 minute intervals, collated into a database and analysed for any vibration values out of the specified tolerances. An alert system was established which contacted relevant personnel by SMS message if readings from the automated vibration monitoring were over certain thresholds with the data formatted into graphs for weekly reporting to the client.

Topographical surveys and 3D Laser Scanning for 3D CAD visualisations at Green's Windmill, surveys for bim

Green’s Windmill is a restored and working 19th century tower windmill in Sneinton, Nottingham.

It was owned and operated in the 19th century by mathematical physicist George Green. After 120 years of disuse the windmill was restored and then reopened on December 2, 1986 and is now part of a science center which is open to the public.

MK Surveys were commissioned to carry out a topographical survey of the entire site and a measured building survey of the windmill. Data was output as 2D line drawings and rendered 3D CAD models.

Structural Monitoring, automated crack monitoring, crack sensors, environmental monitoring

MK Surveys were approached to undertake the monitoring of a crack in a concrete ceiling slab at a well renowned development in the North London area. The client was interested to see how the crack was behaving when the mast climbers were in use.

Automated crack sensors were utilised to enable live monitoring of the crack, recording a reading every minute which was communicated to an onsite datacentre which in turn was uploaded to the cloud were MK Surveys were able to retrieve the data, analyse the results and notify all relevant parties through a warning system should the results be out of tolerance.

The crack readings, along with the temperature were presented in a graph for weekly reporting to the client.

Several major contracts have been carried out by using our HDS 3D laser scanners.

These range from simple Building Elevations to very complicated plant/service areas. One of the most interesting projects was surveying the interior rooms including walls, floors and ceilings of the "Old" British Embassy in Moscow which is now the Ambassador's residence.

After brushing up on our Russian, ("can I have another vodka please?") we managed to complete the topographical survey and laser scanning of the building within the tight programme time and to then post process the 3D imagery over the following months.
