Good morning everybody. It’s my honor to be here this morning to represent Martinus Gamuda. My name is Ronan Collins I’m Irish, which is what the IR stands for in my title and it actually means Engineer in French and I’m gonna tell you a quick story about some of the people that are working for Gamuda. This is John Lim and if you were here this morning for Dr. Ooi’s presentation you may have seen John’s picture. John is the engineer that wrote the software for our autonomous TBM. I met John about a year ago and my reason for meeting John was I was asked to go and look at a project where they were using QR codes to track the delivery of the tunnel segment linings into the tunnels. My background is in Information Management 3d modeling and project management. I was helping John to try and figure this out He told me about the autonomous tunneling machine and it was like a secret, nobody knew about it. I said you’ve got to get out and tell people what we’re doing. So they put together a case study and they put it to the International Tunnelling Association. Last week John and the team and his colleagues won an international award for creating the first self-driving tunneling machine. A very cool piece of technology and very very productive. My presentation this morning is about technology but it’s actually about the people behind the technology, or more importantly, the people in front of the technology. We believe that we have to empower the staff to innovate and we believe that celebrating their success at these kind of events is a very good way of motivating people to come up with bright ideas and share them in the organization. I’m going to use a case study from Kuala Lumpur in Malaysia this morning. This is the MRT project. There are two projects. There’s line 1 which we’ve already completed and is operational. This is one of the Line 1 trains. I’m going to talk about line 2 line 2 is a 51 kilometer alignment with 13 kilometers Underground, through the inner city of Kuala Lumpur. There are 17 construction sites on the alignment involving 10 stations and 7 ancillary structures. These are all major civil engineering projects in and of themselves and when you combine them into a 13 kilometer design and build contract it’s one of the biggest civil engineering projects in Asia. We have been extensively using photogrammetry which is using drones and helicopters to create 3d models of the sites. This is an actual 3d model of the inner city of Kuala Lumpur showing the locations of the stations and you can see this is the famous Petronas Towers. You can see the sites are in in a very dense urban environment. One of the problems with this project is logistics and I’ll come back and talk about some of these particular stations in a minute but this gives you a very good sense of the scale and complexity of the project. Now this being a construction conference, I’m going to be speaking about the use of technology on the sites and how we’ve gone from the BIM design side to the actual construction delivery side to give you a sense of our progress we started this project in 2015. I’ve been personally involved since then and we’re currently through construction works at about 60% to 62% and we are on track to be, excuse the pun, we’re on track to be up and running and operational by 2022 some time between Q1 and Q2 2022 We’ve still got another 2 years of solid work ahead of us. Now one of the strengths of this particular project is the clients involvement. At the very outset the client set out to achieve BIM level 2 and they were using the UK Crossrail as a template and as an example of leadership. We set out to basically replicate what was achieved on Crossrail and we tried to do that without the downsides of Crossrail with the delays and everything else. We’re trying to do a better job than Crossrail which is no mean feat. The objectives of the client was to achieve BIM level 2. We appointed AECOM as a lead consultant. They appointed the design team and they were all contractually obliged to work in BIM. This is one station that was designed in Revit. This station is called Titiwangsa. It is an interchange station between an elevated rail, monorail and an elevated LRT. This is the architectural model. This was designed and created by the architects. You will note that it’s only the architectural elements. All of the structural elements were modelled designed in detail, by the structural engineers separately from the architects. There’s steel, there’s diaphragm walls secant bored piles and an entire concrete structure inside. And these stations being underground stations are heavily serviced and you can see the complexity of the building services and MEP services in this. This is the MEP system. This is the actual air conditioning, electrical and fire. We’ve also got all the rail systems. We have the track systems, we have the comms systems, we have the security systems and these were all modeled by the system-wide contractors. One of the challenges with this process is how do you put all these models together? How do you find coordination issues? How do you solve design problems. We have an entire federated model approach and this is just what it looks like at the detailed design stage. This is pre-construction. This is the level of detail the designers achieved in the lead up to the project. With these tools we can cut sections, we can look at plant rooms, we can look at specific details and the models give us a very clear insight into what we have to build as a contractor. In terms of the use case, the project is divided into four or five key phases and we’re currently doing the final CSDs which is the site based coordination. You can see our uses of the model. We used it at the beginning for doing design, architectural design, spatial design. We then use it for all the design authoring. All of the construction drawings have been produced from the models. This is not a 2d back to 3d process. This is a 3D driven process. We say model 1st, draw 2nd. Then we’ve done all of the design reviews, all the Coordination reviews, all the interface management, all the interface reviews, using these models. And when I say interface reviews, I’ll get to that complexity in a second. But the objective of the MRT, under- writing all this, was to capture all the asset data required to maintain and manage the actual infrastructure when it was built. I’ll tell you how we’ve done that as we go forward. Somebody is moving a lift! This is an overview of all of the interfaces that we have to manage. As a design and build contractor, it’s on our shoulders, to coordinate all of these interfaces. You can see in an underground environment, the sheer number of interfaces and the complexity of interfaces is mind-boggling. We use the models and the model breakdown, to identify all the different interfaces and identify all the coordination that has to be done. This is an example. This is one of the stations this is chancel in so you can see we have all the models created and all the coordination done we’ve altered on the fringe all in the intermediary structures so we got escape shafts we got vent shafts etcetera etcetera so this is what the consultants produced and our challenges the contractor was how do we use this to actually build the infrastructure so going back to the key point about getting people to innovate we empowered our own staff in our design office to first figure out how do we manage the coordination process and I want to introduce you to one that one of the characters this is Rahimi on the your left of the image Rehema is a larger-than-life character he is an absolute 2zs when it comes to Revit and bim and he has completely driven a process for a coordination management i’m gonna show you how he’s done him how many people here have been involved in a big project of sorts whose hair seen a Revit model or a BIM process got a few people right you all know having looked at those models how much effort goes into finding issues and solving issues and we had a process on the project where we would start through this workflow creating models identifying issues running workshops tracking all the issues issuing the reports and then recycling this on a to weekly basis it’s like a washing machine the design consultants go through this every two weeks sometimes they fix the issue sometimes to create more issues but this goes round and round and round and round and it’s very difficult to manage and track so Rahimi and his team set about creating system where they first of all scheduled all these workshops in a rigorous pattern so they were all calendared out so every two weeks every new where they had to be and each one of those boxes is a station site so every two weeks if you were on a station of specification you where you had to be the workshops were done in small teams so we didn’t have 50 people in a meeting room we had the smallest team of decision-makers these are the engineers the gentleman and the right with the yellow is the client this is the coordination engineer here and these are the design engineers working on the models so we had very specific groups of people looking in very specific issues and at the beginning we would find things like cable trays line through escalator pits good luck trying to get out of that station it was a fire with all those cable trays over your heads right so that had to get fixed we’ve got right down to solving pipes clashing with ductwork to make sure that we had no MEP coordination issues so all of these issues were tracked they were numbered they were assigned to summons herself they were given a date by which they had to be solved it was all project managers and this was all done by Rahimi this team using a platform called bim collapse so this is an online system where we can see station by station consultant by consultant what’s happening and we can monitor their performance so we’ve got a dashboard we could see all the issues we could see who is assigned for those issues and the most interesting part of this because we had 10 stations we could track different stations against each other so Rahimi created this tracking chart and these are the number of issues per station and you can see how they’re comparing so we could see which stations were doing better than other stations very useful when you’ve got competitive teams when you want team a to do better than team B and gonna make you’re going worse than there are you gotta up your game so this all came from Rahimi now one of the things that we had to do very carefully was manage exchange of information exchange of models exchange of drawings and to do that we relied heavily on project wise so we had staff working in Kuala Lumpur Singapore Taiwan Hong Kong Philippines and we had two offices in India so we had an office in Delhi and with an office in Calcutta all of those offices needed real time access to the models on a rate on a daily basis so we use this platform to exchange all the information now I’ve told you it’s a very large project but to give you a sense of the scale in terms of data get this to work this is the actual data dashboard from the system this is probably from a year ago there’s over 2.3 terabytes of information on the platform there’s something like 75,000 model files right so when you get to that scale the structure of the information the organization of the information is absolutely crucial and we’ve created a very sophisticated way of managing it by location by discipline by system by models by drawing so it’s very very rigorous it’s very important that you don’t let everybody come for their own system so on a scale of this job we as the construction lead managed all of the information management systems and we basically said what you could do so we use the platform to share the models the visualizations the drawings and specifications the takeoffs all the information that we needed to coordinate and deliver the project is on this platform now we managed to achieve BIM level 2 through rahim EES efforts and there and his team’s efforts and the gentleman in the middle of this photograph is mr. Nick Morecock who’s Rahimee’s boss and Nick was in the UK recently he got the picked up the certification from BRE so MMC GAMUDA are the first level to BIM capable contractor in Asia based on our work on the level on this particular project so through our experience to our knowledge to our systems we’ve been recognized by the BRE as one of the best contractors in the region for doing this this all goes back to how NIC and the team managed the staff to innovate. Rahimee came up with these systems Rahimee’s teams came up with the ideas our next challenge having gathered all the information is to capture the information that the owner needs for the operations facility and it is actually a very complicated task it’s made complicated by the fact that the MRT have never done this before they don’t actually have a full understanding of what data they need so we had to spend quite a long time planning out what information we had to gather and then delivering that information to them in a structured format so to do that we’ve basically is adopted uniclass as a classification standard and we’ve basically trained all the consultants to produce models that are properly properly classified and it’s not straightforward so you have to classify things in four different ways there has to be a classification by where it is there has to be a classification of what room it’s in there has to be a classification for what system it’s part of and then there’s a classification the actual product so when you go through an example this is the entity or the station so each station is unique to have a unique code inside the station or the spaces so this is a platform space it’s given a unique code so if an object sitting in that space we can find it if an object sitting in a different space we go looking for it no space we then need to know what system it’s in so we need to know whether it’s a fire sprinkler system whether it’s a mechanical system and it’s an electrical system so everything has to be properly categorized in that system and then once we get down to the individual components of the project we then have products so whatever handling unit whether it’s a chilling tech tower or whatever it is there’s a code for that as well the challenge with this is that the design consultants have never had to do this before in this in Southeast Asia getting designers to put in this data and put it in correctly is a pane in there so this is very very complicated so what we’ve done is we’ve taken elite from our friends in the UK if you talk to the guys and Crossrail they will give you one key nugget put the data on a diet capture the least amount of information possible and then you can audit it then you can track it then you can check it so what we’ve done is we’ve identified the list of things that we’re only capturing information for so everything on that list we’re capturing information for it was not in that list it’s not being done so we’re not capturing information around ductwork cable trays piping we’re only capturing information about the actual things we have to replace a manager so we’ve managed to convince the owner that that’s enough no more no less and then for each one of those devices or LRU’s this is the information we’re going to capture so we’re given them the classification the tags and everything else so we’ve come up with a data structure that we know we can capture that we know we can deliver and that we know we can order so that’s the asset management site and now I want to talk about about the site side so the surveying team have been the champions in terms of innovation on this project in more than one way so here you can see Phi’s and they’re operating a drone I’ll come back to the drones in a minute the first thing that we did on the project before we did that in design is we scanned all of the existing sites using laser scan so we have 3d point clouds of every single location along the entire alignments to this level of detail and then we use those point clouds to create as built Revit models in this case a structural model of the monorail that we gave to the design consultants and said this is the as-built model at this station location now crack on and do the design because we know that the as-built records are not good enough we know the consultants will just take photographs and not look at the detail sorry survey team have created these three-dimensional point clouds and the as-built models of the site and then about 18 months ago Nick Morecock, I just showed you the photograph of Nick is actually a qualified UAS pilot. He’s actually qualified in UK to fly drones and we set about doing some research about how could we use drones for serving of the sites so this is a drone plan for surveying a particular site this is a drone videoing and under drone doing a survey so we have two drones doing the work right and we’ve done this for this PR campaign so essentially the drones are going along and they’re taking photographs so they take a photograph basically pointing straight down each photograph overlaps the previous by 70% so you’re basically getting thousands of photographs per survey and those photographs are very high-resolution so we’re talking about 5.4 by 3.6 megapixels and if you look into this little yellow box this is actually my cell phone Nick doing one of our pilot so you can get a sense of scale so this is a scale that we’re operating at in terms of photographs the drones typically operated about a hundred meters to make the technology work we also have to have basically ground control points or reference points so here we’re basically using a target that the photographs pick up and they’re recording the GPS coordinates of that target and then what that means is when we create the 3d mesh from the photographs it’s in the site coordinates and we can then use that for site measurement site serving etcetera etcetera so the way we operate we have a very strong safety first approach so we operate in strict areas for the drones so they’re operating in areas where there’s no construction activity they’re checking the drone to make sure there’s no problems with the actual device before we fly it we don’t want it falling out of the sky into the site or worse into the public and then we’ve trained currently we have 30 pilots who have been given special permission to fly on the sites these guys have been trained they know the safety and everything else and they work in pairs so every time we operate we have one guy up right in the drone our girl and we have one spotter the spotter is on a radio in direct communication with the site manager and the safety officer so there’s a complete control over what’s going on with the survey what we use these for well the first thing you can do is you can create proper art or mosaic images so you can create proper autumn images and those images can be used for area takeoffs they can be used for progress reporting and we be used them for GIS and I’ll give you an example of the difference this is an image from Google so if you go on Google Earth can you look for site location this one looks like if you compare that to the ortho photo is a proper view from above and then we can plot the TBM pads through that so we can actually see what property lines were going under so it’s very very powerful from this from a desktop serving perspective we’re using it for progress reporting so this is actually a sequence taken every two or three weeks of a particular site and you can see the excavation going through in sequence so we have surveyed every two or three weeks and we have basically a progress model now this is a three-dimensional model that’s dimensionally accurate to the survey grid so this is not an image so people see this others just photographs this is a three-dimensional model I can measure the depth of the excavation in any one of those instances or I can measure the area at the volume and then some of the team that’s working with Nick we figured I’d had to link the model from the survey to the BIM so we could actually see that’s the basement excavation we have to reach and we can compare our progress against our target so we actually have basically an unknown destination we have to get to and we can then use the survey to see how close we’re getting to it so this is a very useful way of showing to a client how far we are away from actually completing an excavation Anybody who’s familiar with these you’ll be able to you’ll know that you can use these models for takeoff so we can actually measure linear dimensions but more importantly from the surveyors we can measure volumes so in this example the operator is basically pulling out an area of the site and they want to work out a cut and fill for creating a level deck so here you can see them setting their boundary and then the operator will set the parameters so we’ll use basically as a twenty-eight point five meter level that we want to create we’ll set the grid and then the software will tell us that we need to remove eleven and a half thousand cubes and fill nine and a half thousand cubes that is transformational when it comes to serving and it’s transformational because the survey takes no more than two hours and the post-processing in the computer takes less than half a day so you can go out on site survey an entire site in a couple of hours have this level of information available to the engineers by the end of the day and there is no way around it the surveyors tried to do that it would take them a week and by the time they were finished it they would have changed the levels and everything else the calculation we’ve got so this technology is transformative now I want to introduce you to two more characters in this process Tony Joseph is our GIS manager and this is Mr. Pua who is our surveyor Mr. Pua has been pushing the guys to use the drones for as many ideas that came up with he’s the one that’s encouraging the innovation he’s the one enabling the innovation Tony has transformed the delivery of the information to our engineers our project managers and even to our client tony is a GIS expert and for those of you know GIS to me it’s a two dimensional mapping platform but it’s much more than that Tony’s been able to take all the models use GIS as a gateway this is a web browser so this is chrome you can go onto the web if you know the URL you can access the model from the drone survey and the Revit model from the BIM team and you can overlaid them on a browser you don’t need to have Revit you don’t need to have Navisworks all you need to have is an internet connection and a password and you can get a three-dimensional model of your site add a key point in time and you can even go back and look at historical records so we have project directors who don’t have the time to visit 17 construction sites who will sit down with a team of people and go through these models in an office environment so tony has been able to transform the way we deliver the information to senior staff okay and we see that as very very important and one of the other things that Tony has done which i think is really cool is tony has taken the information from the tunneling machines so we’re running eight tunneling machines we know in real time where they all are if you go on the GIS platform you can actually see all the tracks of the TBMs and you can tell exactly where they are underground and you can see here this is the auto mosaic image and you can see the red and blue lines indicating the tunnel drives and they will actually tell you exactly where the tunneling machines are in the actual underground space on the platform on the cloud in real time now the last character one is Yu Shu is David’s and I think David somewhere here at where’s David there’s David David has been leading our digital site forms business and David is now based here in Sydney and he’s helping out spill the marks in this commuter business david has helped train up a huge team of people hundreds of people to use what we call our digital forms or paperless construction and what we mean by this is that we’ve taken all the traditional paper processes on site whether it’s a progress report a safety inspection incident report a quality inspection all the stuff that you see engineers walk around with clipboards and bits of paper in their back pockets and all that stuff we’ve taken all that and digitized it so all of our inspections for all the construction sites are now done on iPads our Samsung devices and all that information is captured in a structured format so what we’ve started doing is speeding up all the processes on site so if you want to get approval for an activity on site you don’t have to get a piece of paper signed by two individuals and you have to go around it can all be done digitally so you can fill in the form it gets immediately notified to the recipients they can start it out and you can send it straight back so we’ve sped up by a huge factor the approval process for works on site but what’s intriguing about this is we set out to digitize the paper process for two reasons one to be more efficient and two to capture the information much more systematically every time one of these forms are filled in it’s recorded on a cloud system it can’t be erased it can’t be eroded we never lose the information we lose paper all the time but what we discovered is we achieved those two goals productivity and security but we’ve also unlocked something completely new which wasn’t foreseeing we’re now using these systems to capture information for reporting what we’ve realized is we can start running analytics on these reports so we can start capturing historical information and comparing it one site to another site one week to a previous week one quarter to a previous quarter and we can start to understand from a data perspective what’s happening on our projects so we’re currently running an innovation project to look at data dashboards in this case we’re using Cognos IBM Cognos in terms of how to be improve even further with the use of these digital forms our understanding of what’s happening on site and our goal is to get to real-time progress monitoring using dashboards our current reporting is two weeks behind the activity so if you get a report from one of our sites it’s about two weeks behind what’s actually happening on site and most people are used to that you send a whatsapp you get the construction director he puts together a few reports you get a few Excel tables a few Word documents a few opinions and you get a feeling of what’s happening this gives us a real-time information what’s happening on a jobsite this is what we’re currently working on so to wrap up the key message here is that you can have all the technology you like but if you don’t enable the people to use it you won’t get these innovations and is my honor to stand here and represent the team of people have done this over the last two to three years they’ve won awards all over the place they’ve won awards for tumbling Association they’ve won awards and the software vendors and we’ve started to get recognitions through people like the BRE for our level 2 BIM certification so thank you very much for your time this afternoon if you have any questions fire ahead thank you all very much [Applause]
