Across the AEC sector new technologies utilising reality capture techniques enabled by laser scanners and drones are bringing change. Closer validation of construction progress, driven by Digital Engineering and the transformative BIM process are at the heart. The concept of Virtual Design and Construction is helping an industry challenged by cost overruns, to embrace new technology, share information and gain increased productivity.

Continuous as-built – the truth about construction validation
Andrew Evans, Product Manager, Topcon,
Nick Salmons, Principal Laser Scanning Surveyor, Balfour Beatty Major Projects,
In 2015 near real-time construction validation was possible. The hard facts though, were that the procedure’s complexity required specialist survey and scanning teams and was only of interest to projects totally committed to the philosophy of Digital Engineering. Balfour Beatty are one of those companies leading that digital charge. In 2018 they now have access to a solution for near-real-time construction validation utilising a combination of hardware and software, enabling site engineers and not specialist survey and scanning crews to complete day-to-day validation tasks in a third of the time previously required. Huge time and cost savings result. Costly mistakes and project hold-ups are avoided.
Andrew Evans is a Product Manager for Topcon Positioning Systems, he has expertise in laser scanning, rapid survey techniques and digital photogrammetry. He works every day to increase efficiency for the construction industry though the use of intelligent hardware and software solutions.
Nick Salmons is Principal Laser Scanning Surveyor for Balfour Beatty Major Projects. He has been scanning for more than 15 years. If it can be scanned Nick has probably got the point cloud. Focused on maximising the efficiency and accuracy of laser scanning data collection he has identified a number of different hardware and software solutions that are becoming a streamlined and effective workflow in 2018.

Mobile Mapping, a 21st century tool for the construction industry
Mark Reid, VP Product Management, GeoSlam
The recent collapse of Carillion and profit warnings of rival Capita, must act as a wake-up call to the construction industry. For too long, cost and project overruns have been considered a necessary but unavoidable evil. This must change. The Government’s Digital Built Britain programme, unveiled last year, focuses on the transformative power of BIM and how fully embracing digital construction leads to more efficient working practices, greater collaboration, and ultimately, more projects delivered on time and on budget. The beating heart of a project is the 3D BIM model – one which is current, built in an open data format, accessible and understandable by all project stakeholders. Mark Reid will be showing the role handheld, mobile mapping plays.
Mark Reid is a results orientated business manager with over 15 years’ experience in business development and project management. A driven geomatics professional with specific expertise in advanced laser scanning solutions and the introduction of disruptive technologies. Proven history of sales success across Europe, Middle East, Africa, and India. Effective manager of resources and people to achieve on target goals and timely project delivery. Experienced in the management of multi-million pound budgets and diverse portfolios of services and products across a wide range of industries.

Urban Virtual Design Construction – the beginning of VDC and integrating project delivery
Peter Bo Olsen, Technical Director, MT Højgaard
MT Højgaard published a paper in November 2017 about their digital practices with Urban Virtual Design and Construction (VDC) as part of the early involvement of competencies from the general contractor, other relevant parties and part of the good start of Virtual Design and Construction (VDC) and Integrated Project Delivery (IPD). The white paper provides an introduction to Urban VDC as an effective start-up on digital project collaboration, contributing to subsequent cooperation in the form of Virtual Design and Construction (VDC), and Integrated Project Delivery (IPD). Urban Virtual Design and Construction (VDC) as exemplified by Bellahøj in the municipality of Copenhagen.
Peter Bo Olsen, Technical Director Urban VDC, MT Højgaard Denmark, from 2014 been responsible for research and development of best practices with Urban VDC. Peter Bo has had the role of a Ph.D. supervisor since 2012 for Ph.D. students who have been affiliated with Universities such as Chalmers University of Technology Gothenburg in Sweden, University of California – Berkeley, Stanford University and Technical University of Denmark. Peter Bo is co-author of the book A practical guide to BIM in construction and infrastructure projects and white papers about the value of BIM, VDC and Urban VDC in practice on construction projects through the inclusion of both civil engineering and land surveying. Peter Bo has since 2015 participated in the European BIM standardization work in the working group CEN / TC 442 focused on the framework for the good digital cooperation in the construction industry.

Every 3D detail matters; big point clouds tamed
Steven Ramsey, HDS Technical Manager, Leica Geosystems
High Definition Surveying (HDS), also known as 3D Laser Scanning or Reality Capture, is now a mature technology. However, as technologies have evolved to capture faster and more data bottlenecks in processing, deliverable extraction and sharing occur. Steven Ramsey from Leica Geosystems will share how innovations in software are keeping ahead of the curve to handle increasingly bigger data challenges. He will focus on how, by embracing next generation software, users can increase their productivity, be commercially profitable and offer a sustainable competitive-edge. Accessibility of sharing deliverables will be explored with a modern, intuitive user experience.
Steven Ramsey is the HDS Technical Manager at Leica Geosystems UK & Ireland. Steven has 12 years at Leica Geosystems and has worked in the geospatial industry since 1990 as a land and building surveyor, specialising in HDS surveying since 2000. With a broad background in commercial surveying and laser scanning and many years at Leica Geosystems at the cutting edge of HDS development, Steven is well placed to guide both newbies and well established scanning professions in to the next evolution in HDS Scanning.

Use of Unmanned Aerial Vehicle (UAV) technology to aid terrestrial scanning for reality capture and BIM
Keith Wakeley, Drone Survey Instructor, Drone Pilot Academy
Capturing reality using terrestrial laser scanning is now part of the BIM workflow. Huge quantities of data can be captured quickly. Access to roofs, difficult to reach areas or dangerous structures however, present a hurdle to capturing the full picture. UAV technology, together with photogrammetric software and increased computing power, enables us to capture this missing data quickly and safely with usable deliverables. With pre-planning and an integrated workflow we are able to combine data of facades with photogrammetry derived point cloud data of the upper elevations and roof to produce a coherent, accurate point cloud model of the external envelope of buildings for feeding into the BIM workflow.
Keith originally studied civil engineering before taking a role as a land surveyor. For the past 14 years Keith has worked as a building surveyor for both loss adjusters and independent surveyors managing large loss insurance claims together with providing defect diagnosis and validation surveys. Over the course of the last three years Keith has worked on development of the aerial surveying bringing together his experience of land surveying and building surveying with new technology to deliver quality deliverables in this fast developing sector. Keith, the first UK PIX4D Certified user, uses his experience in these industries to instruct on the popular drone Survey Course at the Drone Pilot Academy teaching how you can use drones to optimally collect and process survey data. Keith is the Team Leader of Woodhead Mountain Rescue Team, a voluntary organisation providing rescue services to the Police and Ambulance services across the Northern Peak District.
