Thursday, 22 March 2018, Kuching: Just eight months into the start of an ambitious Highway Information Modelling (HIM) project to convert the masses of traditional 2-dimensional (2D) engineering design drawings to 3D models, modelling for 8 works packages of the Pan Borneo Highway Sarawak is now complete. The balance 3 works packages are expected to follow soon after, by month end.
Kudos to the HIM team, comprising 55 young Sarawak engineering graduates and supervisors, for completing their first project on target!
Working in teams of 5 or 6 members, the group has put in long days and at times nights, to produce Malaysia’s first ever Highway Information Modelling for Pan Borneo Highway Sarawak’s Phase 1 totalling 786 km.
Put simply, HIM is a combination of Building Information Modelling (BIM) and Geographical Information System (GIS). Lebuhraya Borneo Utara, as Project Delivery Partner for the Pan Borneo Highway Sarawak, is leading the charge for the wider use of BIM in the local construction industry.
Prior to doing the real work to develop the 3D models, all Modellers underwent an intensive one-month training at BIMASIA 3D VDC Lab in Kuala Lumpur to learn the software’s technology and its capabilities.
Impressed with the performance of our Pan Borneo Highway Sarawak Modellers, lead coordinator Mohd Nazif Mohd Ridzuan said, “As coordinator, I am very happy with their performance. They are good with computers. They are fast learners. And they are dedicated to completing their tasks. That’s why the team has been able to complete the 3D modelling in just 8 months.”
The newly completed 3D modelling engineering design of the WPC stretches have been progressively shared with our Project Managers.
Next on the cards is the task to update the 3D models with construction and shop drawings.
“The Modellers for 8 works packages have already started updating the 3D models based on the latest construction drawings since end of February this year”, adds Mohd Nazif.
Combined with WebGIS which includes orthophotographs captured from drones, and as-built 3D mesh at all bridge areas, the integrated 3D models provide valuable data for construction monitoring.
Armed with the 3D models and data from drones flying the alignment, captured on a monthly basis since August 2017, Project Managers at the site now have better tools to identify clashes during construction, such as underlying utility cables or road alignment or engineering discrepancies. Upon discussion with contractors and consultants, our Project Managers advise the HIM team on amendments to the design, changes in quantity estimates and sequence of works to avoid these clashes. These amendments will be updated in the 3D models and subsequently reflected in the works programme.
“With HIM, errors in construction and clashes will be reduced, enabling the project team to make more accurate technical forecasts to improve planning and execution”, said Mohd Nazif.
The team will continuously update the 3D construction models until completion of the Highway. After that, the Modellers will move on to develop the as-built drawings into 3D models – important for the next phase of the asset management life-cycle, i.e. maintenance and operations of the Pan Borneo Highway Sarawak.
