A construction project would usually would require construction lending & investment to finance the project. In order to obtain lending, the drafting up of finances reporting would be requiring a plan and cost review. A plan and cost review document is heavily reliant on construction drawings & documents to gain insight on how the feasible the project is, financially. This brings about the necessity to ensure the ‘quality’ of the construction plans & drawings is up to standard for a smooth process of construction lending.

Many a times, plans are found to not be fully compliant, with a lack of information, and a few back and forth are required to specifically fix these inadequacies.To avoid unnecessary unimpressive delays to construction or financial applications, it is best to make certain that the plans are first made in to be at a grade of primed condition. To assist you with this, we’ve listed out a couple of common oversights which could help you in avoiding Construction Drawing/Plan Mistakes that might come back to haunt you. Alongside, we can provide you with some tips where Bluebeam Revu can assist.

1. Incomplete Plans

A full set or a complete set of construction plans consist of numerous sheets of various technical drawing – which includes architectural, mechanical engineering, electrical engineering, civil engineering, structural engineering, and other disciplines. The larger and more complex the project, the more sets of drawings there will be. When the plans are not complete, the project will come to a halt or standstill till the information is available, and also – due to a lack of information at the initial stages, there may be an increased risk to other aspects of the project when they were commenced with the absence of the missed details.

This problem is especially common when a complex project like an apartment building has been drafted by a home builder or an architect who does not have extensive experience in larger projects. If the incomplete drawings are allowed to go to construction, they will lead to change orders when the contractor gets on site and starts pointing out the missing pieces. This leads to overruns in budget and delay.

2. Uncoordinated plans

Following up with the first point, there are also instances where the architectural drawings don’t coordinate with the mechanical drawings, or mechanical drawings don’t coordinate with electrical drawings, resulting in collisions between items such as having ducts, pipes or electrical conduit running straight through steel beams. This might be due to designs being done with the absence of certain drawing plans as was mentioned in Mistake 1. However, this may be also due to the use of superseded information when doing the design. The lack of coordination again leads to change orders and will affect the project negatively in terms of costs and timeline, if the project is already underway.

3. Wrong Drawing Sets Reviewed

The architectural process naturally produces multiple progress sets of drawings, from the original conceptual design drawings to progress sets of construction drawings to, finally, the “For-Construction” set that the contractor will use to build the building. Quite commonly, progress drawings are also sent for review and even the “For Construction” set, there could be potential sets of revisions,  from building department reviews or owner dictated changes. As a result of these revisions, poor organization of the drawings can introduce errors such as having not the latest drawing being reviewed, shared, used and approved.

As an example, a set of Rev A drawings show a certain size pipe coming out of a retention pond. Between that drawing set and the Rev B drawing set, the builder may be told that they need a larger pond, that requires larger stormwater pipe. However, the Rev A drawing was wrongly sent to the piping supplier. This mistake can be very costly after the wrong piping size has been purchased.


Features in Bluebeam Revu that can help

However, fret not. There are functions in Bluebeam Revu which can assist you in avoiding these mistakes. One of the helpful features is the Slip Sheet feature. This feature allows you to slip sheet large quantities of drawings in a single, easy batch process that matches your new revisions to the correct originals automatically. By just loading your originals and your revisions, Revu will auto-match them. This helps you to not miss specific sets and have the latest drawings denoted. You can also choose whether or not to transfer over all of your markups, whether you want those markups to be flattened, and you have an option to automatically stamp old pages as “superseded”. The Sets feature is also another feature that assists, by allowing users to open a collection of documents in a single view with the pages organized in a sorted order, specified by revisions or addenda. Users can navigate through multiple files as though they were one document without actually merging them into a single file. The old revision files will be marked as Superseded, as to avoid the mistake of using the wrong revision drawing.
