City Surveys is a UK-based structural monitoring and engineering surveying firm established in 2003. They use the latest total station technology to monitor a wide range of structures, including bridges, tunnels, railways, and more. Their monitoring services include automated total station systems, remote target monitoring, track monitoring, pressure monitoring, vibration monitoring, and tilt monitoring. They have developed their own online monitoring portal and wireless telemetry systems to provide clients real-time data on project sensor readings from any location. City Surveys works with several railway and construction firms and aims to provide reliable monitoring services and cost savings over competitors.

1. STRUCTURAL MONITORING CPD

2. City Surveys is one of the UK’s most respected and frequently contracted structural monitoring, structural investigations, rail engineering and engineering survey firms. We are a vibrant, thriving company that challenges your expectation of what an engineering survey firm can do. Established in 2003, we have grown and diversified into a highly capable and experienced ‘all service’ survey firm. WHO DO WE WORK FOR? WHO ARE WE?

6. HOW DO WE DO IT? Should any one sensor go ‘out of bounds’ or, indeed, show an error, an immediate SMS text alert is sent to any number of designated numbers. Likewise an email is also sent instantaneously keeping both our engineers and the client completely informed. Any number of phone/email contacts can be included. While this system can be installed using a conventional ‘wired’ approach, City Surveys has invested heavily in creating our own unique wireless devices. In doing so we have created a monitoring system that is impervious to cable strikes and the everyday damage that can be inflicted on exposed equipment whilst on site. PRESSURE MONITORING Our specially constructed 500-bar rated pressure transducers can be connected to hydraulic props and emit an analogue signal which, in turn, is converted to a digital signal via a series of acquisition modules. The signal is then transmitted automatically via GPRS mobile broadband to our secure, stand-alone off-site server. Our sophisticated electronics are able to receive and transmit up to three readings per second.

7. By integrating vibration sensors into our unique Monitoring Data Portal, City Surveys can assess both vibration frequency and amplitude across a variety of engineering projects. Potential applications range from monitoring the levels of vibration causing discomfort to humans to assessing the effects of piling or demolition upon surrounding structures. All sensors and equipment are calibrated to BS6955 and are fully IP-rated ensuring a weather-proof and reliable service for our clients. VIBRATION MONITORING TILT MONITORING Our tilt and displacement systems (which detect movement of 1000 th of a degree) can be used to measure the response of structures to influences such as loading, settlement or subsidence. The accuracy and insight that these techniques provide has proved invaluable to clients needing to monitor large structures such as bridges, dams, cranes, sheet piles and party/retaining walls.

9. GPRS WIRELESS TELEMETRY Data is transferred from our sensors in near real-time to City Surveys’ secure, off-site server via a wireless GPRS telephony system. The portal software then interprets the information and alerts staff to any alarm events. Our T24-Bsi GPRS industrial base stations (modems) are flexible and robust units and, in conjunction with our unique software, can be used to configure all devices within their range. This device can listen to all linked sensors and transmit data packages to a wide range of devices, therefore making control and group measurement very simple.

10. ONLINE DATA MONITORING We have invested significantly into developing our own, bespoke monitoring software that is included free of charge as part of all monitoring projects. This enables ourselves, our clients and their clients to view up-to-date, real-time data received directly from the sites without leaving their chair, wherever they might be in the world. Our system has been specifically designed to be incredibly user-friendly. As a result, all interested parties (including insurers and other ‘none technical’ personnel) and not simply your engineers are able to navigate the Portal with ease... Simply choose the site you wish to view and be immediately presented with a live ‘traffic light’ view of your site. At a glance you are given the current reading and alert status of each sensor as well as the temperature of the site at that moment. Simply click on the sensor icon and have the previous minute, hour, week or even year’s readings delivered to your desktop in either graphical or tabular format.

11. ULTIMATE FLEXIBILITY Data for each site and individual sensor can be viewed both historically and in real-time by simply changing the time/date range within the portal Unique to the marketplace, our user-friendly customer interface is so simple that clients are regularly up and running within 30 minutes of receiving their login details.

12. Data from any range can be printed off or downloaded as a universally compatible CSV file which can then be used/manipulated in any number of ways by any contemporary data handling package... Data within your chosen range (stretching from the last 10 minutes to the entire project) can be displayed both graphically or in tabular form…

14. City Surveys is a highly experienced, well respected and thriving firm of surveyors and monitoring engineers operating throughout the UK. Our unique range of monitoring services are guaranteed to provide not only peace of mind, convenience and significant cost savings but also a valuable tool during the construction process. You can, quite simply, predict certain problems, preventing situations from reaching critical levels and reducing time, costs and risk in the process. They can be used either in isolation or in conjunction with our wide range of other engineering survey and investigation services.
