It’s no secret that Bluebeam Revu is among the most powerful software tools used in the design and construction industry. As I’ve observed in my career as a Bluebeam Certified Instructor and blogger, construction professionals of all specialities and trades are using specific features and tools in Revu to maximise efficiency in their workflows. I’ve teamed up with Built, the Bluebeam Blog, to contribute a series of articles on how professionals across the industry can get more value out of Revu.    

As technology has fast become the standard for the industry, specialist contractors are not far behind. In fact, specialist contractors can build custom tools to bid, track installs and QA/QC jobsite walks – all in one drawing.  

Let’s start by tackling the bid part. For this example, let’s pretend we’re a commercial window manufacturer doing an estimate on a store-front window system. 

As a manufacturer, the bidding process can make or break a project before it even starts. A detailed, accurate count of materials and labour is crucial to know the true cost. With projects being so competitive, sloppy bids can quickly become a race to the bottom just to get the work. 

What other obstacles are there? Well, how about every estimator on the team has a different system or method as well as a different percentage of waste or profit margin. How is consistency even possible with a ruler, notepad and calculator? 

Of course, as soon as you finish, a revision comes across your desk. How can we update an estimate to match the new scope of work when all our notes, maths and markups are lost in the recycle bin? 

Collecting data 

Considering all the parts of a window system, how do we quickly and accurately measure and count everything? The answer is custom measurement tools – and a little creativity.  

First, let’s break down the parts of a store-front window system and the tools I would use for estimating material and labour costs. (Image 1) 

Estimates for Assemblies

Area Measurement: Total measurement of Assembly (SF Install) used with a price per square metre gives us our installation labour estimate. 

Count: Counting joints per Assembly (Store-Front Joint) used for the cost of materials estimate. 

Area Measurement: Different types of glass (SF-G1, SF-G2, etc.) again used for the cost of materials estimate. The perimeter length also provides the amount of caulking. 

Spaces: This tool is traditionally used to indicate markups within a ‘space’ or room. However, we’re going to use it to create an assembly, so all parts are associated with a specific mark number. 

To be honest, I built my best guess of time, cost and installation practices into formulas in the Custom Columns in the Markups List. When I build custom tools it’s extremely important for me to listen and understand legacy workflows. I am by no means an expert at Store-Front Glass. With the infinite flexibility within Revu, it’s my job to customise Revu to match the expert’s workflow.  

Let’s take a look. 

Navigate to the store-front Elevations within the architectural drawings to see the required assemblies. (Image 2)

Here you can see store-front assembly SF-8. Let’s go through the steps of applying our custom tools: 

With Snap to Content turned on, draw the area of each individual panel of glass. Be sure to use different types to match the material type spec out (GL-1 Standard, GL-1T Tempered). (Image 3)

Next, we place a Joint Count. Simply drop the symbol (SF-J) on the mullion grid as required. (Image 3)

Then, using the SF Install area measurement, trace the overall area of the entire frame (you can also click and drag). (Image 4)

Now, for the best part. Go to the Spaces Panel and create a new Space around the assembly naming it with the assembly Mark Number (SF-8). In this case, the Space is light purple, slightly larger than the frame. It’s important that all individual parts are completely inside the Space. (Image 5)

Now that we took less than a minute to label the parts, let’s look at the Bill of Material results in the Markups List from left to right. Revu also allows you to customise the order of the columns. (Image 6)  

Estimates for Assemblies

Space: Sort the Markups List by Space; you can see all the parts fall under the assembly Mark Number (SF-8). 

Subject: A clearly labelled itemised parts list. This could be broken down into segments – for example, setup, data collecting and processing data. 

Width: Length of each horizontal frame and a total at the top (10.56577008 linear metres). This information is automatically provided by the area measurement. 

Height: Length of each vertical frame and the total at the top (8.280166320000001 linear metres). This information is also automatically provided by the area measurement. 

Measurement: Total measurement or count of each part. 

Layer: Having spent more than 20 years in production using AutoCAD and Revit, I like to build Layers into all my custom tools for more flexibility when viewing or filtering the Markups List (install, glass, etc.). 

Fab: This is an ‘Hours to Fabricate’ formula column using the area measurement along with a factor of two hours per square metre, a shop labour rate of US$35 per hour, times five assemblies (US$57,589 Fabrication Total). 

SF Caulking: With the length of vertical and horizontal frames provided, I simply enter a formula to account for caulking on the inside and outside of the glass, 7.0104 linear metres of caulking at US$8 a tube, times five assemblies (US$430.12 Caulking Total). 

SF Hours: This is an ‘Hours to Install’ formula column using the overall area measurement along with a factor of 0.17 hours per square foot, a $50 per hour on-site labour cost, times five assemblies (US$6,865.46 Install Total). 

# Thus: After running a Visual Search for the Mark Number on the plans, I can highlight them indicating they’ve been accounted for and manually enter the number of times this assembly exists on the project. Since we cannot enter a quantity for ‘Spaces’, I entered ‘5’ for the number of each individual part indicating five total assemblies. 

TOTAL: Simply the total cost of Fab, SF Caulking and SF Hours (US$64,884.58 Total Cost for five SF-8 Assemblies) 

Processing data 

Now that we acquired all this information so quickly, there are a couple of different ways to use the data.  

Sometimes I’ll leave out all the custom columns and formulas and use Quantity Link to bring all the data to a template estimate form in Excel. In this case, I wanted to show how powerful custom columns can be directly inside of Revu. Another option: I could export the Markups List to a CSV file to later import into another estimating software. 

With just a few custom tools, assemblies are possible in Revu when those quantities merge with pricing formulas within the Markups List. Now with very little training, you could have just about anyone in the office colour the elevations with the correct tools allowing the estimator to backcheck.  

(In full transparency, we’re not able to Quantity Link data from custom columns in Revu. You would want to link the measurement data and build the formulas in Excel rather than Revu. I’ll show another great example of assemblies using Quantity Link in a future article.)  

There you have it – creating assemblies in Revu. The intent of this article is to leave you inspired and thinking ‘could this apply’ to my speciality. Whether a cabinet/millwork estimator, steel detailing, residential or commercial flooring, low voltage audio/visual or security, these can easily be applied. Or maybe precast panels, or electrical, mechanical and plumbing pre-fabrication assemblies.
