Build Without Rework
SiteAware Team | Jan 19, 2022
A New Generation of Digital As-Builts leave your details and we will be in touch as soon as possible.
Are you tired of constantly updating as-builts and still not having an accurate representation of the plans on your jobsite? Imagine you can track in real-time the exact geometry, dimension, and location of each element installed. SiteAware DVC is the only platform whose technology turns as-builts from a contractual obligation to a true reflection of how a building was constructed and an asset for the property.

The Role of As-Builts in Construction
As-builts also called record drawings and red-line drawings are detailed blueprints submitted by a contractor after the project is complete. In theory, they show the exact geometry, dimension, and location of each element installed on the jobsite—each embed, PT tendon, and more—and reflect all changes made in the process.
As-builts play a key role in the life of a building in providing a detailed record of how it was actually constructed—which may differ significantly from the designed specifications due to modifications and changes made in the field and the shop to installation and design.
The Traditional Approach and its Challenges
Not all that long ago, a contractor who wanted to document a change made in the field or to the design relied on a highly manual process in which updated versions of sheets were slipped into the plans. Workers on the jobsite were able to distinguish between old and new plans visually—the lower right corner of the old version was folded up—and could view a compiled history of the revisions made throughout the course of the project by flipping through the sheets.
RFIs and other change documents that were issued with just a writeup or a sketch—not a complete reissued sheet— had changes red-lined or marked up by hand in red. Sketches or detailed revisions were physically cut out of paper and taped onto the respective plan.
These dog-eared and red-lined sheets were ultimately used to compile the as-built drawings for the project. This traditional approach historically had significant challenges. Trades did not always update the plans they were working from with new sheets as they were issued, so it wasn’t uncommon for them to build from an outdated set. This, in turn, led to errors that frequently required rework.
The Digital Approach and its Challenges
In recent years, as-built documentation has largely gone virtual, with changes logged within Procore, PlanGrid, and other document management tools. These digital tools enable teams to work collaboratively to create a continuously updated single source of truth that drives safety, quality, and cost improvements.
But even with digital tools, the process is still somewhat manual; someone has to digitally mark up the plans with changes made during construction, and that introduces the potential for human error. In addition, while the digital plan management approach is a significant improvement over the traditional approach, trades can still find themselves working off an old set of plans if new sheets aren’t uploaded to the platforms.
Because of this, both approaches—the traditional and the digital—have significant limitations. Manually updating plans, whether with the traditional or digital approach, requires a significant amount of time to manually update plans, so few if any workers do so with the level of detail needed to make as-builts accurate. The general contractor depends on each of the trades to mark up their own set of documents throughout the project with every change, then turn them over at the end of the project, but this is often an afterthought—markups are rarely dimensional or done to scale.
DCV the Game-Changer
SiteAware DCV digitally verifies the conformance of every constructed element to its plans; with easy-to-use digital as-builts that document every element, SiteAware DCV provides continuity of the level of detail between the designed and installed elements. This allows project teams to prevent compounding errors, including clashes with other plans, critical missing elements, and the persistent misreading of plans. Avoiding errors leads to better as-builts because what is built is closer to plans.
With SiteAware DCV, multi-layered digital as-builts are maintained for future reference as a virtual x-ray of the structure, shell, and interiors. This enables a record system to protect against latent liabilities and disputes. It informs post-construction building modifications, tenant improvements, facilities management and assurance to the owner as the property evolves over the years.
SiteAware DCV also removes the biggest barrier to using building information modeling (BIM) for facilities, not just for design or construction. With more accurate as-builts, digital photographs, and visibility into each element installed—including what’s in the deck, in the walls, and above—SiteAware DCV improves the BIM model.
