The HVAC Project Manager’s New Best Friend
plant room for a HVAC

Being a Project Manager for a commercial HVAC system is a full-on responsibility.

You’re in charge of critical plant infrastructure. You need to be accountable for so many different things.

Fundamentally, you can’t let things freeze, cook, or get moist.

You also need to have a deep understanding of spatial mapping, dimensions of the plant room, making sure design and documentation are up to scratch, and ensuring compliance of works to specification. If it all falls apart, the buck stops with you.

We understand you’re human and this is a tall order.

So, take a breath and let us introduce you to your new best friend — the 3D laser scanner.

3D Laser Scans and HVAC Projects – A Marriage Made in Heaven

You may have heard of this world-class emerging technology. If you haven’t, it is sure to be everywhere soon. It is best practice par excellence.

3D laser scanning has been predicted to “revolutionise the future of plant room engineering.”

The 3D laser scanner itself is portable and lightweight. It requires only one person to carry and set up.

Our expert, Dave Starr, can bring it on-site and run the scans for you.

The scanner is similar to a large camera on a tripod. The head spins and captures millions of points with laser beams.

Everything it sees, it records.

The lasers are not harmful to people or materials and they effortlessly capture highly accurate data in what is called a ‘point cloud’.

These point clouds of data can then form 3D geometric records of the space.

The data calculate floor areas, heights, steel widths, all spatial dimensions, and elevations for a plant room.

It is far-and-away the quickest and easiest way to capture floor plans, and with an extraordinary level of accuracy.

To get good coverage of the site, a few scans are likely to be made from different vantages.

Within a couple of hours, you get an as-built condition in three dimensions.

This is extremely useful for mechanical engineers and HVAC services in health, education, infrastructure, or other commercial industries such as telecommunications.

Working with the Scan in Revit

At Drawable, we use the Faro Focus s70. With a range of 70 metres, it can capture pretty much any plant room.

The scan data is stored on an SD card in the scanner unit. The card can be removed easily and exported to Revit for immediate 3D modelling and visualisation.

It captures almost one million points per second and the accuracy is within one millimetres.

The Faro also takes and saves high definition colour photographs during the scan.

Once the files are exported to Revit, you can spin the model around, cut sections, and zoom into areas, and figure out if new concepts will fit into the space.

The scan can be dropped into the existing building information model (BIM). It can show any safety problems that could arise and will help will scheduling and planning. During a construction phase, the 3D scan can also verify that work that has been done is according to the BIM.

Early Clash Detection and Avoidance

Did we mention seamless cooperation with various trades? With a 3D laser scan in Revit, you can see in the 3D visualisation, if there are any potential clashes.

This has got to be worth a fortune in client and stakeholder relationships.
