The Role of Surveyors in the Evolution of BIM

Building information modelling (BIM) is becoming more commonplace within construction sectors globally, combining technology with improved collaboration to better manage projects and give them the best chance of complying with time and budget constraints. However, the BIM life cycle and efforts to espouse it are almost futile if surveying is taken out of the equation or, more realistically, brought in too late. It can be good to have a structure that is successfully using BIM to be delivered on time and within budget, but if it or any of its components are in the wrong position the consequences can be...

Trimble Launches New R12 GNSS Receiver

Trimble has introduced the Trimble R12 GNSS receiver, a high-performance global navigation satellite system (GNSS) surveying solution. Powered by an all new real-time kinematic (RTK) and Trimble RTX positioning engine, it features innovative Trimble ProPoint GNSS technology that empowers land surveyors to quickly measure more points in more places than ever before. Surveyors who work in challenging GNSS environments can use the Trimble R12 receiver to help reduce both the time in the field and the need for conventional techniques such as using a total station. The new Trimble ProPoint GNSS technology allows for flexible signal management, which helps mitigate the effects of... (read more)

Chasing BIM: How Surveyors Can Shape the Future

Greater Utilisation of Technologies at Hand
While research shows that many organizations recognise the power of building information modelling (BIM) for streamlining construction and infrastructure projects in a seamless online environment, survey and geospatial professionals can do more to deliver value in the 3D environment. There have been countless presentations and papers on the definition of BIM. This article makes an attempt to provide some practical insights on how surveyors can leverage the BIM revolution to benefit their businesses. The good news: there is a general consensus among geospatial thought leaders that the design and construction industry has reached a tipping point. The more that surveyors... (read more)

How Will the Surveyor’s Role Look in 10 Years’ Time?

Over the next ten years, the surveyor’s workflow will become quicker, safer and easier because of new technologies like scanning, mobile mapping and UAS photogrammetry. Virtual layout, aided by the increasing use of augmented reality technologies, will require fewer physical stakes in the ground. Due to the transformation of the physical world into a digital one, digital twins will take centre stage, with surveyors called upon to convey meaningful information from the model back to the physical world. Demand will increase for surveyors’ expertise in time-based analysis of changing site conditions, such as monitoring installations for volume-changing and deformation analysis.... (read more)

Casablanca’s Medina Buildings Monitored during Tunnel Construction

Vibrations during the construction of a new 1,890m tunnel adjacent to Casablanca’s Old Medina, the 250-year-old section of the famed Moroccan city, challenged the stability of its historically important buildings. It was essential to monitor in real time the effects on the Medina’s aging buildings and to confirm that the construction work meets all engineering standards and guidelines. Therefore ETAFAT, a geospatial information acquisition and processing company, used the Nikon XF total station to perform more than 100 daily inspections. The ETAFAT team relied on optical targets placed on building facades whose coordinates were determined by forced centering to complete... (read more)

Seeing the Future: AI, BIM and Digital Twins

Digital Construction Week 2019
During Digital Construction Week (DCW), which was held at the Excel in London from 16-17 October 2019, there was one seminar stream on geospatial surveying and two specifically on building information modelling (BIM). But relevant topics such as artificial intelligence (AI) and visualization, as well as BIM, cropped up in many of the other sessions. The most used buzzword was 'digital twin', which was heard in many talks and in the exhibition booths. The term digital twin is used quite flexibly, but essentially it implies that an object must have a digital representation which can be presented visually, i.e. a virtual... (read more)
