BIM Laser Scanning
HH Angus was engaged to create a 3D Revit model (LOD 300), accurate to reality, of the existing structure and visible HVAC, plumbing and electrical infrastructure. This model was delivered to the client for their use in 3D coordination of their high voltage switchgear replacement project.
The 17,000 ft2 area was scanned using a Faro S70 Laser scanner, with the scans subsequently registered using Faro Scene software to create point clouds. Point clouds were then processed in Edgewise modeling software and used to automatically extract and model walls, structure, piping, conduit and ducts, before being imported into Revit. This efficient process resulted in a very significant 60% reduction in modeling time. The remaining MEP infrastructure was modeled in Revit, with special attention paid to the location of the entry and leave points within rooms for all MEP infrastructure, in response to the client’s requirement.
One of the challenges of the project was the lack of easily accessible data required to create the Revit model. Recap pro or Faro Scene software is needed to review the point clouds and images; this software required licensing and installation on individual machines, which prevented it from being easily accessible to everyone on the project team. The software also requires additional computing power to run smoothly, and this presented an issue for machines that did not meet the software requirements.

Deodorizer Installation
HH Angus served as prime consultant for this new deodorizer processing plant. The new installation more than doubled the oil refining facility’s existing capacity.
Palm oil is the most widely-used edible oil in the world. Deodorizing is the final stage in refining the oil, and is required to remove odoriferous material, free fatty acids and other undesirable minor components, in order to produce a bland oil with a good shelf life.
The deodorizer tower is 30m high and 2m in diameter, with connected boilers, pumps, etc., that required connection to the existing production plant located adjacent to the expansion area. Due to the height and sectioning of the deodorizer, it had to be built in two stages.
One of the key challenges of the project was the site constraints. Two feasibility studies were produced as part of the investigation. It was determined that a new building was needed, rather than trying to install the deodorizer in the existing building.
In order to accommodate the electrical needs of the deodorizer process, a system upgrade was required to the switchgear. The upgrade allows the client the flexibility to install other major equipment in future.
Enabling projects for the deodorizer installation included a nitrogen tank installation, cooling water system, a new natural gas let down station, and new gas feed to the site.

Modeling in 3D
As a special feature of the project, HH Angus modeled the installation using Plant 3D software. The installation was quite complex, and creating the model reduced both design time and the construction schedule. The contractor was able to see a comprehensive view of the design, confirming locations of pipes, etc.
