The Sessa Aurunca Cathedral is therefore a building of superb beauty dating back almost one thousand years, with an absolutely unique feature: it is “the other original”, an almost exact copy of the church at Montecassino which, as is well known, was destroyed by bombing during World War II and subsequently rebuilt. The two buildings differ only in the number of naves: Montecassino has five, while Sessa Aurunca has three. The Sessa Aurunca Cathedral is one of the infinite “pearls” of Italian artistic heritage. Indeed, it stands out for its beauty and historical significance: despite the changes made over the centuries (Baroque and eighteenth-century additions), the cathedral still bears direct witness to the typical religious architecture of the period, combining structural rigour, Christian symbolism and a number of refined Byzantine-style elements (such as the splendid mosaic floor).
Despite its obvious significance, the Sessa Aurunca Cathedral is not well-known among the general public and is overlooked by “traditional” tourist flows. For this reason, the diocese and the municipality of Sessa Aurunca in the Campania region of Italy decided to launch the “Sessa Aurunca 3D Project”, a communications project designed to promote the Cathedral and provide the associated services and products.
The “Sessa Aurunca 3D Project” has several goals and is broken down into seven specific points that will explore new frontiers within the world of communications: the publication of academic and scientific reports and articles; the organisation of conventions, seminars and events; the production of stereoscopic 3D animations and videos, with the creation of a You- Tube channel and dedicated videos; the creation of a “360-degree Virtual Tour” with a database and “multidata” to “explore” the Cathedral using computers and mobile devices; the creation of thematic apps and a website; and the production of a “docu-film” about the project and the technologies used. Regarding this last aspect, Danilo Prosperi observed: “Part of the success of this initiative can be attributed to the FARO Focus3D Laser Scanner, an extremely precise device that we used to scan the Cathedral’s architecture, which provided us with a point cloud or, more precisely, digital data that we were able to use in our various activities.” The data acquisition phase involved 38 scans made inside and outside the church, including the crypt, and took just over half a day. “The quality of the FARO Focus3D Laser Scanner enabled us to acquire extremely high-resolution and high-precision images with very low margins of error, which was fundamental for the scanning of extremely beautiful details, such as the mosaic floor, the ambo, the spiral Paschal candelabrum and the crypt on the lower level.”
The data gathered was then processed in SCENE, the FARO software for the management of scanned data, designed specifically for the Focus3D. This software was used to create and edit videos and images for the 3D Virtual Tours of the Cathedral. “SCENE,” Danilo Prosperi specified, “allows us to easily process the scanned data and quickly generate particularly complex high-resolution equirectangular panoramic images”. Danilo Prosperi stressed: “We believe that the FARO Focus3D Laser Scanner is the best technology on the market, not only due to its extreme precision, but also because it is so flexible, fast and easy to use. In fact, it is a compact instrument that is very lightweight and easy to move from one scanning position to another.” He concluded: “The collaboration between FARO and the Master’s in Architecture, Sacred Art and Liturgy at the European University of Rome has only just begun. Given the quality of the results, we plan to use the FARO Focus3D Laser Scanner in the future for other projects aimed at promoting highly important monumental sites of great beauty.”
With Laser Scanning continuing to gain popularity, more workflows than ever now rely on the unparalleled precision and speed offered by the latest in scanning technology. We here at FARO continue to bring new instruments to the table, and legislative changes revolutionising the ways in which project data is handled, getting it right in terms of data capture, processing and modelling is more critical than ever. One company who pride themselves on being well ahead of the competition is Worcester-based Bury Associates: Opti-cal caught up with MD Steve to talk all things buildings, BIM and Bury.
In a rapidly changing project landscape, survey businesses like Bury’s occupy an increasingly pastoral role when it comes to guiding clients through the project lifecycle; and they’re not alone – with specifications now littered with demands for BIM, tighter phase collaboration and the need to navigate complex software suites, knowledge in the supply chain is king. They often say that a workman is only as good as his tools, but even with the FARO Focus 3D X330, what truly sets Bury Associates above the competition is the sheer breadth of knowledge, and committed attention to detail that has characterised the business right from its humble beginnings. Commencing back in May this year, their latest project has focused around the documentation and refurbishment of several of the core buildings of the one of the UK’s major academic institutions. With plans to overhaul the structure of the existing buildings, the University commissioned Steve and his colleagues to comprehensively scan, model and deliver a functional Revit BIM from which plans to renovate the central portion of the building could progress.
Having used cutting-edge data modelling techniques since the early 2000s, Bury Associateshave spent the past fourteen years building a reputation as one of the UK’s most experienced topographic and measured building surveyors around. “The project was essentially to carry out scans, and produce a BIM of several buildings and key external areas”, explains Steve; “Scanning started on site in May 2014 and the last of the models was issued to the client in October.”
“The FARO Focus3D X330 has already been used on several other prestigious projects, providing the point cloud for a large Rights of Light model in central London – again, it proved to be invaluable.”
“The end goal is to completely transform a whole major block of buildings so as to make more use of the space available”, he continues, “at present, the main courtyard surrounded by large U-shaped building isn’t really being used at all, so this projects aims to put the space to better use by installing extra glass blocks and lecture theatres. Much of the scanning has been carried out using our new Faro Focus3DX330,” says Steve; “There weren’t many vantage points from which the buildings’ high roofs could be seen – and those that were visible were a good distance away – so a high powered scanner with sufficient range was necessary to pick up the detail needed to model everything as accurately as possible. We were really pleased with the quality of the point cloud we got from the X330; it was clean with little or no noise, and with full coverage even in areas covered in dark slate tiles.” Even with the significantly reduced site time enjoyed by those opting to use high definition 3D data capture methods, the project still demanded a huge amount of raw data from which to accurately model the buildings in question: “In total we’ve performed well over 1000 scans, with more than 200 of those being taken in the voids above suspended ceilings,” says Steve.
“Although using 3D Laser Scanning for as-built projects such as this one has been documented to cause some problems in terms of attributing good, solid data to the resulting 3D model, I think this is where our wealth of experience comes into its own, because intuitively we’ve already got a fairly good idea of the kinds of features we’re likely to come across in a building of this kind. Obviously, it’s not a complete solution because every building is different, so where we could we were scanning up above suspended ceilings using elevated tripods, and putting the scanner up through ceiling tiles!
As a company at the cutting edge of their art, Bury have always been eager to embrace the very latest in 3D data capture methods and their project solutions often stretch far beyond the initial remit of full three dimensional documentation. Now offering some of the most comprehensive project solutions around, Bury are no strangers to Laser Scanning; “The X330 has already been used on several of our other prestigious projects,” says Steve, “and once again it proved to be invaluable. The data collected using the X330 has been used to create a 3D Revit Building Information Model, which as well as basic structural information also includes detailed plant and MEP features.
As with many projects of this kind,it’s the work that takes place in the back office that often accounts for the majority of the time – and Bury’s latest endeavor is no exception, with months set aside for meticulous data processing. “The project has been quite a long one, and if we stay on track we’re due to finish around the end of this month,” he says, “Overall it’s progressed really well and we’ve had some excellent feedback from the design team; the challenge has been to ensure sustained collaboration between our team – using Revit to create our BIM – and the architects for the project who have been working in ArchiCAD, in order to maintain the smooth transfer of intelligent 3D information from one software suite to another.”
“I think it’s critical with all of the projects coming our way nowadays to get the modelling side of things right because so often we’re modelling everything – MEP and so on –not just the architecture,” Steve continues. Contrary to the swathes of survey companies seeking to harness the momentum of the industry ‘BIM buzz’ by simply outsourcing their modeling work,Bury are one of the few businesses who have taken the time to really perfect their modelling art in-house. With major legislative changes on the horizon for businesses at all levels of the supply chain, Bury Associates are way ahead of the competition; now proudly boasting BIM deliverables amongst their regular survey services. “We have been working with and modelling in Revit since 2007 – in truth way before many of our competitors – so in terms of the skill set we have at our disposal, we’re pretty confident in the quality of modelling services we can deliver from the survey side of things.”
“We always have, and will continue to be as hands-on as we possibly can with our projects”, says Steve: “The argument for outsourcing increasingly critical modeling work is often based on the assumption of cost-saving, but at the end of the day, saving twenty percent on modeling costs pales quickly when you consider the sheer amount of errors that so often occur as a result of businesses trying to cut corners. Maintaining the integrity and accuracy of intelligent data is crucial to the success of any project hoping to experience any kind of real success.”
It is no secret that where large-scale major investment is concerned in the current economic climate, infrastructure is a serious front-runner. As one component of a multi-pronged assault on rectifying the UK’s extensive debt crisis, Cameron’s government has pledged billions to the preservation and vast improvement of the country’s arterial infrastructure systems in the hope of stimulating a kick-start for the country’s long-term economic growth. With high-profile projects such as HS2 and Crossrail at the vanguard of the £36billion major infrastructure investment plan, the subject of national infrastructure has become one of 2014’s hot topics. Opti-cal caught up with Ted Harland of Tri-tech Site Engineering and Land Surveys in a bid to get the inside scoop on one of this year’s largest projects; the high profile £300million upgrade of the A1 between Barton and Leeming, that upon completion will see journey times in the area cut by as much as twenty percent.
Tri-tech themselves are a Yorkshire-based surveying and site engineering company, who since 2005 have gained a solid reputation in supporting and facilitating project success for both public and private sector clients
“The project is essentially a £300m upgrade of the existing A1 dual carriageway to 3 Lane Motorway”, explains Harland, MD of Tri-tech, “upon completion, the project will also provide a number of local access roads to serve the local community, and significantly improve safety in the area [which at present lacks the local access roads necessary to accommodate the area’s numerous agricultural vehicles.]”
Falling beneath the broad umbrella of major infrastructure projects for 2014/15, the A upgrade sets the tone for contemporary project process in its use of 3D Laser Scanning Technology, as well as the firm insight into futureproofing the venture’s work through BIM (Building Information Modelling) workflows. “There has been a big push nationwide to start to deliver projects through BIM”, says Ted; “This in turn with the recent development of Scanners, PC Software, and PC Hardware has meant that now more than ever 3D laser Scanning has become a viable option for data collection for this kind of project.” “We have used Opti-cal for number of years now for the supply and service of all our equipment …Their support and service is second to none”
“We were asked by the Morgan-Sindall Carillion Joint Venture (MSCJV) project team to survey a number of existing bridges for the structural design team to process”, he explains, “some of the existing bridges are to be kept, as well as a number modified to suit a new 3 lane Motorway. After having various discussions with the design team about their specific requirements, and whether they could handle such large amounts of scan data, Tri-tech choose the FARO Focus3D X330 model for the job largely because it is the ability to scan at a far.
” Since its arrival on the market last year, the FARO Focus3D Laser Scanner from global manufacturing powerhouse FARO has evolved in tandem with the changing requirements of the survey teams using it. In November last year, the original S120 model was replaced by the first of the X series units – the X330 – which boasted considerable range whilst maintaining the compact 5kg housing that has gained this particular brand of scanner well deserved industry-wide recognition. “In the past we have used the Focus3D S120 to scan a number of buildings for a client”, he says, “The results were excellent, however on this project we knew we required the additional range of the X330 to confidently scan the structures from both sides of the carriageway and get good results. Because we only have access to the side of the motorway sometimes the distances needed to be scanned would have been right at the limit of the S120, which is why we went for X330. In terms of the hire itself, we have used Opti-cal for number of years now and so it was natural progression for them to supply the scanner and all accessories. Their support and service is second to none.”
Speaking about the data captured at the site, Peter Robinson of AECOM’s specialist design team said, “The use of the X330 FARO scanner by Ted Harland of Tri-tech has provided the A1 Dishforth to Barton structures design team with invaluable information. The [sheer] level of detail obtained from the surveys has left a number of the design team speechless, and has allowed [the highly] accurate modelling of existing structures.” He continues; “thanks to the coordinated point cloud obtained from the surveys conducted, we discovered that the original surveys carried out [at the site] were in fact inaccurate, which could easily have led to costly issues on site.”
Here, Robinson highlights the very issue that awards Laser scanning its rightful place at the heart of much of the industry’s recent lean towards Level 2 maturity BIM workflows; that the data you get out of a model will only ever be as good as the data you put in. And where Tri-tech is concerned, no expense has been spared in ensuring total accuracy for MSCJV and the holistic success of their project. “There was quite a lot of prep work prior to the scanner arriving on site,” Ted continues, “control had to be established at each structure using GPS and then tightened up using a total station; all stations were then digitally levelled to tie them into the site network. The beauty about scanning and scan data is that you capture everything in one visit – which at the end of the day saves the project both time and money.”
“We managed to scan all the structures in 4 days with a total of over 40 scans taken”, says Harland. “The processing was then done the following week using the Faro Scene, and the data exported out of FARO Scene Software in a format ready to be imported into Autodesk Revit/Autocad. We know this data is of an exceptionally high quality, and can now be used to design and model all new additions or changes to the motorway bridges – it also provides a real snap shot of what is there now as a record forever, in true 3D.”
With work commencing in March this year, the venture is by no means a small undertaking; “The project is due to be completed in mid-2017,” says Ted, “and I am confident that should there be any further survey work of bridges or structures, laser scanning will certainly be a first choice – not only by the designers but by the site team too.”
Following the completion of a major contract involving the scanning and generation of a large chemical processing site, Advanced 3D Laser Solutions were the recent successful bidder for similar complex projects related to the scanning of five large UK fuel distribution terminals. Advanced 3D Laser Solutions client’s primary requirement was the preparation of precise piping isometrics for all terminal lines, in advance of inspections related to compliance with the Pressure Systems Safety Regulations.
Two advanced FARO Focus 3D Laser Scanners, supplied by Opti-Cal Survey Equipment, were used to accurately complete the in-depth site survey work. The easy to use FARO Focus Laser Scanner is the smallest and lightest laser scanner on the market and is the ideal tool for fast and exact indoor and outdoor measurements in three dimensions. Used throughout the world within the most demanding of conditions, the ultra-portable Focus Laser Scanner enables fast, straightforward, and accurate measurements of objects and buildings. It records architectural façades, complex structures, production and supply facilities, accident sites, and large-volume components.
FARO is the world’s most trusted source for 3D measurement, imaging and realization technology. Technology from FARO permits high-precision 3D measurement, imaging and comparison of parts and compound structures within production and quality assurance processes. The devices are used for inspecting components and assemblies, production planning, documenting large volume spaces or structures in 3D, and more. FARO’s 3D measurement technology allows companies to maximize efficiencies and improve processes.
The Focus3D X 330 offers an extra-long application range of 330m, whilst the Focus3D X 130model is a mid-range device offering precise scanning up.
Both scanner models are equipped with GPS and offer the ability to perform scanning even in bright sunlight. Remote scanning as well as almost limitless scan data sharing via SCENE Webshare Cloud makes the laser scanning solution truly mobile.
By the use of FARO’s Focus Laser Scanners and four sets of ‘Flexi’ spheres for target referencing between scans, Advanced 3D Laser Solutions’ experience in the field ensured that all surveys were completed with minimal impact to the sites’ efficient operation. In total, more than 1000 individual precise scans were completed across the five terminals. Typically, Advanced 3D Laser Solutions completed the site scanning of each terminal in 3-4 days. The collected point cloud files were then quickly converted into easily manageable 3D CAD files.
SI2G S.r.l. (which stands for Sistemi Informativi Intelligenti p er la Geografia, or “Intelligent information systems for geography”) is a spin-off of Marche Polytechnic University established in 2008 by researchers with many years’ experience in the various disciplines involved in the study of terrain and the environment based on computer science and photogrammetry. The company deals with the acquisition, analysis, processing, archiving and distribution of “environmental data” in digital format, using an integrated systematic multidisciplinary approach. It provides services such as remote scanning of terrain, photogrammetry, topography, cartography and ICT.
Eva Savina Malinverni, Associate Professor of Topography at Marche Polytechnic University, explains how SI2G recently came to invest in a Laser Scanner Focus3D, the innovative laser-scanning tool from FARO that provides extremely precise yet simple 3D scanning
The FARO Laser Scanner Focus3D is actually a very compact device, weighing barely 5 kg and measuring just 24 x 20 x 10 cm. A technician can carry it around wherever and whenever it is needed. What’s more, the WLAN technology makes it possible to start, stop, view or even download scans remotely.
The imperial city of Huế, declared a UNESCO World Heritage Site in 1993, is probably the largest and most famous architectural site in all Vietnam. It was from here that the emperors of the Nguyen dynasty ruled from 1802 to 1945. Its design was based on the imperial palace of Beijing and comprises walls, moats, fortified gates, bridges and decorations that make it a truly atmospheric setting of great artistic and historic value. “Scanning it would have been very complex and time-consuming had we used the normal photogrammetry techniques.” The FARO Laser Scanner Focus3D, on the other hand, enabled the SI2G team to complete the work in just a few hours and to obtain truly astounding results with just 17 scans.
Thanks to the FARO Laser Scanner Focus3D, a highly flexible tool that is very quick and easy to use, the technicians at SI2G S.r.l. were able to scan the magnificent East Gate of the imperial Vietnamese city of Huế, capturing every detail of its form and geometry with the utmost precision, despite the difficult weather and operating conditions.
