These coordinates were stored in the Trimble Access Monitoring Module. The Monitoring Module was used to control the measurement workflow and automate the measuring process with Jordan able to pre-define how many measurement rounds were required and to which targets, along with the measuring order and amount of time between each round. take the monitoring work from semi- automated to fully automated, this is easily achievable by upgrading to the full version of Trimble 4D Control. The existing data can be imported from T4D Lite, to allow historic information to be used as the project progresses. Jordan concludes, "Access time is tight on this project and the reliability of the Trimble S9 combined with the fail-safe deliverables generated by T4D Lite has enabled us to deliver exactly what the structural engineers require, all within their specified 24 hour period. As ever KOREC support is on hand when we need it bringing another level of assurance to what we do and based on the success of this early monitoring job, Greenhatch will be undertaking additional engineering and survey work on this site." * Trimble FineLock is smart tracking technology that enables the S9 to detect a target without interference from surrounding prisms, as well as measuring around 670 horizontal and vertical angles per measurement, giving very precise results. ** The Trimble Access Monitoring Module gives the surveyor a nice workflow to create the monitoring job, measuring routine, QA options and reports. Once the points have been measured, the data logger takes control of the process, freeing up the surveyor to undertake other tasks on site. Once all the measurements have been completed, the surveyor can view the results, create various reports on site and either email or synchronise them via the Trimble Connect cloud back to the office along the measured job file, which can be imported into T4D Lite. Whilst all data is currently being delivered well within the client's specified 24 hour deadline, it is Jordan's aim to fully exploit the functionality of T4D Lite so that the process becomes almost instantaneous. In particular, this will be assisted by T4D Lite's ability to create fail safe, clear deliverables (reports, charts, graphs, scatter plots etc) without the need to manually manage Excel spreadsheets. Back up from the SX10 If a reading over a trigger value occurs, the Greenhatch engineer can immediately alert the client (who has a plan of all the targets for fast identification of the problem area) and provide an output report from T4D Lite showing delta values there and then. In these cases, Greenhatch has offered to undertake a 3D scan with the Trimble SX10 Scanning Total Station. Whilst the client was initially dubious about the concept of using 3D scanning for deformation purposes, they have since been won over by the SX10's mm survey grade accuracy and see it as a useful back-up that will assist in reassuring the structural engineers. The SX10 will also be used later in the project to create 3D scans for use with the project's BIM model. Jordan reports that the monitoring system is functioning well and the demolition team delighted with the speed and quality of the deliverable and the added value of the SX10 scans if required. As the project progresses to include the monitoring of both the heritage aspects of the site as well as the slab which is constructed above a Thames sewer, additional prisms will be added.
