5 Reasons to Get As-Built Drawings for Architectural Design and Engineering Firms


There are those times in the life of an architecture or engineering design firm when the universe throws up a challenge that feels curiously uncomplicated on the surface. You enter a building thinking that everything inside will be as the drawings that someone approved many years prior showed. You assume the walls will be exactly where the plans say they should be. You expect the plumbing and wiring to be exactly where they are shown on the blueprint, as if whoever built the place followed a recipe. It feels like a basic expectation. It feels like something that should never surprise anyone. But then reality reveals itself, and you realize that the structure is different from your expectations in those early documents.

The painful epiphany often comes when you realize that as-built drawings exist for a reason: they were constructed to clarify the real story. They tell the truth about where the walls really went, where utilities really ran, and how the final project really took shape. They give you a version of the building you can rely on, not an assumed one where everything still might be the way someone once imagined it to be.

That’s where architectural design teams and engineering firms shake their heads in frustration and fascination, because buildings evolve, plans change, and construction teams make adjustments on site for a whole gamut of reasons that range from very practical to just plain mysterious. The result is physically real but seldom identical to the pages that first defined it.

As-built drawing services avoid such shock. These provide the firm with a real-life reference that will support planning, renovation, and maintenance, apart from future upgrading. They help reduce project confusion, get rid of unnecessary delays, and support clear communications across all project stakeholders.

Cad Crowd is a great avenue to look for freelance professionals to deliver high-quality ‘as-built’ drawings. The wide range of experts has experience in architecture and engineering, right down to the accurate site measurement. This is one of the good places where you will be connected with professionals who take messy or outdated documentation and turn it into something that finally reflects reality.

Having that in mind, let me outline the reasons why as-built drawing is a must for architectural and engineering firms: You would be surprised to know that investments in their creation are not just one of the options of being helpful, but indeed are one of those strategies that avoid headaches, surprises, and unnecessary reworks in future projects.


🚀 Table of contents


Reason 1: They give the real story behind a building.

Somewhere, there is something peculiarly comical in the contrast between the ideal world of architectural plans and real-world conditions on the job site. In plans, you see walls of perfectly straight geometry, duct runs angling neatly into neat corners, and utility lines presented as if they politely agreed to align themselves in predictable routes. Then, construction starts, and in comes the reality that guests who didn’t read the dress code.

Interference requires changes to structural framing on a whim. Electric lines get rerouted because their original path ran into some obstacle along the way that no one foresaw. Plumbing lines move because the on-site measurements conflict with theoretical dimensions. Each trade makes the change. Time passes, and little changes add up to a layout that does not look exactly like the original documents.

This planned-versus-built disconnect is one that quickly becomes very real to architectural design firms when renovation, addition, or maintenance projects have to be done. Without ‘as-built’ drawings, assumptions are usually made from old documents by the teams involved. That is the kind of decision leading to surprise demolition, unexpected delays, and those odd moments of disbelief.

That uncertainty is nullified because it is correct on the as-built drawing. These  are the drawings of structures that outline what the building really looks like today, not what it looked like at times when the paper design was done. They enable the engineer to understand, with a lot of clarity indeed, the structure. They let architects confidently plan renovations instead of making plans based on outdated assumptions.

Knowledge of the right things right from the start of the project makes everything else easier. No more wasted time in guessing where your missing utilities. Unknown conditions behind walls wouldn’t cause unnecessary confusion. Instead, teams just have a sound foundation on which to start planning.

That is one of the many reasons companies want professional as-built drawing specialists. You want those people who go out in the field, take down all the measurements, document every system that’s on site, and give you a drawing with accuracy. Cad Crowd prides itself on CAD design freelancers with domain expertise. They are well-qualified to support architectural and engineering teams in the documentation of existing structures-accurate to realistic drawings, not theoretically exact drawings.

Reason 2: They prevent costly surprises in future projects.

Now, imagine you are walking onto a renovation job site with complete confidence, knowing the existing drawings are going to drive your decisions. You break out the old documents and start planning. Absolutely everyone thinks the information is correct. Then comes demolition: a wall comes down, and utilities appear that aren’t supposed to be there. A conduit emerges from someplace where nothing was supposed to exist. The ceiling opens up, and ductwork nobody expected to find stares at you. That is when you can tell that someone back in history changed things and never fixed the drawings.

These discoveries cause delays and force crews to stop work. Meanwhile, architectural design experts are forced to revise their specifications, engineers to redesign components, and the whole team is compelled to readjust its thinking in conformance with the realities of the newly encountered site conditions. Time is wasted, costs increase, and frustration mounts.

It’s the as-built drawings that reduce these headaches, documenting what’s really there. With accurate documentation, renovation planning can be a whole lot easier and predictable. The team knows the layout before a single hammer swings. There is real awareness of what systems are in place. Architects can make informed decisions. Engineers can calculate loads and connections with confidence. Contractors can develop more accurate estimates and schedules.

Just one surprise behind the wall can send half a project phase off the rails. That is where accurate as-built drawings help you avoid the surprises. In avoiding these surprises, firms save money from costly redesigns, unexpected demolition adjustments, and emergency solutions.

It is far easier to correct things at the planning stage, rather than trying to fix problems once construction has started. The planning stage, therefore, with accurate as-built drawings, becomes far more reliable. This is one of the reasons why so many firms find themselves reaching out for skilled professionals who have experience in these types of projects. Cad Crowd connects you with architectural planning and design services that understand these challenges and know exactly how to properly document a building, knowledge that will prevent architectural and engineering teams from costly catastrophes because of poor documentation.

Reason 3: They widen and normalize the communication between participants.

Perhaps one of the most undervalued aspects of as-built drawings has to do with communication. Most projects in architecture and engineering involve a huge number of stakeholders, whether it be the clients, contractors, consultants, or facility managers, each with different needs, perspectives, and priorities. Clear documentation aligns everybody with the same information on the same page.

These drawings become obsolete as they get passed around the group and lead to misunderstandings. One vague detail is interpreted one way by the contractor and another way by the structural engineering experts. An architect assumes certain dimensions that no longer apply. Facility managers make decisions based on documents that no longer depict the configuration of a building. Inaccurate information becomes a silent source of misunderstandings.

That, however, takes a complete turn for the better with as-built drawings. They unify the understanding wherein, at the same time, with accurate data, while working on it, it gets a lot easier, and the conversations get more productive. The team reduces confusion, cuts back-and-forth clarifications, and collaborates confidently while looking at a reliable representation of the structure.

The customers are equally pleased when they see the drawings clearly, especially when they have a mental picture in mind, like setting up a document for future improvements. Such documents give them an overview of their building. They thereby benefit, in the process, from a much better understanding of their place and its deficiencies. They can be involved as well with the design team once they grasp the information being presented

As-built drawings are the universal language among project teams. Translating the physical building into a reference that everyone can follow is important. Generally speaking, where the documentation is correct, the general workflow improves, and what might seem complex proves manageable.

Cad Crowd freelancers would also tell you that clarity is everything in terms of documentation. Most professionals understand well that a good drawing is not only a technical document but also one more way of communication, which develops teamwork and collaboration.

Reason 4: They help in smoother renovation planning and facility management.

There’s a certain kind of headache that appears only when a person tries to plan a renovation without proper documentation. It starts with mild confusion, grows into concern, and finally matures into full-blown unbelievability. You know the feeling: You walk through a building holding a set of drawings that someone insisted were reliable. You confidently examine the pages, glance at the space around you, and think everything is straightforward. Then you begin measuring. Suddenly, nothing lines up. The walls that appear perfectly aligned on paper show strange angles in real life. A room that is supposed to be rectangular has a tiny slant that no one ever mentioned. A column appears where the drawings insist there is open floor space. It’s a situation that turns an otherwise ordinary project into a puzzle that feels almost taunting.

That is where the value of the as-built drawing experts comes in: they eliminate guesswork from future planning. When architects begin redesigning a space, they have to have accurate reference material. They must know where the existing walls are. They need to know how the mechanical and electrical systems are laid out, and they have to see how the building has changed over time. Renovations cannot function based on speculation; they need certainty.

As-built drawings provide that certainty. They represent today’s reality, not some idealized drawing from yesteryear. That allows architects to design renovations that truly respect the structure, while engineers can adapt mechanical and structural systems without surprises. The contractor has confidence that the plans he receives for construction align with real conditions. In fact, the whole renovation process could be that much more efficient if preparation is based on accurate information.

It is equally high on the facility managers’ side because they operate the building, troubleshoot the systems, replace equipment, and adjust layouts. All these jobs become exploratory missions if the changes or updates are not properly documented. Many times, they have to open the walls, ceilings, or even the floor, just to find systems set up differently than what older drawings might say they should be – costly, time-consuming, and entirely avoidable.

Suppose the facility manager is to replace a mechanical unit. The old drawings depict that the route of the duct is perfectly accessible, while actually, this ductwork splits into two different directions because a contractor working in the past had changed things during installation. Consequently, there is no as-built drawing to be had; confusion and delay are felt by the facility manager, while it would have been predictable if the documentation had been there.

Correct ‘as-built’ drawings assist the facility manager and engineering design experts in planning preventive maintenance; this is because when the mechanical systems are correctly documented, teams can find the intervals when replacements are to be made with great ease. They can monitor ageing components and understand the actual conditions of the building they maintain. Surprises are fewer that way, and with better performance, the equipment will last longer.

All these benefits amount to smoother operations and fewer budget complications. From architectural firms to engineering teams, from contractors to facility managers, clarity is provided by accurate drawings. This is where it matters that professionals who can specialize in ‘as-built’ documentation are hired. The freelancers at Cad Crowd pretty well understand the technical challenges that come with field measurement and the analysis of buildings. They will be able to assist in the development of drawings to serve as reliable references for a number of years.

Reason 5: They reduce liability and improve compliance.

Liability is one thing any architectural and engineering firm has to face. There are just so many technical decisions about construction projects, structural integrity, code requirements, and safety standards. If that documentation becomes outdated or wrong in some respect, that risk goes through the roof. A small mistake in a drawing can leave room for a bad assumption, which may lead to a design decision creating an unsafe or non-compliant feature, and no firm wants that.

Accurate as-built drawings support the documentation of compliance with a building’s final configuration. Architects and engineers will refer to what actually exists on a site when investigating code requirements relative to future renovations. Systems-fire protection, electrical distribution, and ventilation systems-will more easily be checked against regulations, especially for MEP drafting services.

Consider the architect who redesigns an exit route. If, in fact, the original drawings show an existing hallway to be wider than it actually is, the new design may not meet egress requirements. In that case, of course, the possible problem is unidentified now, and risk arises. With accurate as-built drawings, dimensions can be verified, and the design team has the capability to know at the outset whether something will comply.

The latter relies on the calculations to check for load paths, structural connections, and mechanical routing. Where the drawings show a displaced beam or a duct that no longer has any part of the original path, the calculations shift accordingly. This is one fear: just one wrong reference point might turn upside down all the structural assumptions, which is not something any professional wants to find out after construction has already started.

As-built drawings also facilitate the process of permitting: renovation plans filed with local authorities can require showing specific documentation with regard to existing conditions. The accuracy of as-built drawings makes the whole approval process much easier and faster because it shows the regulators that the company is working with reliable information. This greatly limits the need for supplementary explanations or resubmissions.

Liability further extends to client expectations. Each time firms go on-site, with renovation plans based on obsolete drawings, surprises are bound to happen. Those surprises are the changed orders for cost and timeline extension, and moments when clients rightfully question the process. The more accurate the as-built drawings are, the fewer disruptions will occur; it thus helps in sustaining trust between the firm and its clients through transparency by the architectural design and drafting company.

Another big factor is that so many owners now expect proper documentation at the conclusion of a job. In truth, through experience, owners have caught on to just how important precise drawings are to use in planning the future. They also realize that these protect their investment when architectural and engineering firms do not provide this value. This then represents a lost opportunity to deliver comprehensive service.

Accurate as-built drawings require skilled professionals, and a great deal of attention to detail, technical knowledge, and site measurement experience are needed for such work. Cad Crowd can provide this level of professionalism; it’s where firms can locate those specialists who take the time to document structures correctly. It reduces liability in return, while code compliance is maintained along with professional integrity.

How as-built drawings improve workflow efficiency

The five reasons outlined above depict most of the major benefits, but a more general theme can be elaborated from them, too; namely, as-built drawings smooth out the workflow of each phase of the project. In other words, when true information is at hand, each team member is able to work better: planning gets more organized, communication gets clearer, construction goes smoothly, and maintenance gets predictable.

Think of how project delays normally start: a team hits an unexpected condition, the condition requires a redesign through architectural remodeling design services, the redesign requires new approvals, the approvals require clarifications, and the next thing you know, what should have been a two-month project stretches out to four. More accurate as-built drawings can prevent many of these delays by at least reducing the variables unknown to them.

They also support digital workflows. Many firms today work with advanced modelling tools, including BIM platforms. These systems are very dependent upon accurate base drawings. If the starting model is wrong, then all of the workflows built upon it will carry those same inaccuracies. As-built drawings enable the creation of digital models that actually represent existing conditions for better, more reliable simulations and analyses.

This will also enable better coordination among the trades. The mechanical, electrical, plumbing, and structural teams all need good background information upon which to base their work plans. When they start with correct drawings, then more effective conflict detection means there are fewer clashes during construction. That saves time for everybody.

Scheduling even improves: with few unexpected discoveries, the contractor can plan the activities more precisely; equipment can be ordered on time, labor can be assigned with efficiency, and workflows will continue to get more predictable and cost-effective.

All these enhancements culminate in better relations amongst project partners. Greater trust develops when the documentation is reliable. The teams also start working much more smoothly with one another, and the clients stay assured about the process of all those involved. Accurate ‘as-built’ drawings bring stability, and everybody profits from that.

The human side of as-built drawings

Notwithstanding all the technical aspects involved in the as-built drawing, there is a quite amusingly human side to this too. Since people make decisions out in the field, not many buildings have been built just exactly according to plan. Construction workers adapt to real-world challenges, structural engineering experts quickly adjust in order to resolve conflicts, and contractors work around space limitations not anticipated by drawings. Each decision was made because of practical realities entailing working with actual material and existing structures.

These human decisions are documented in the as-built drawings. They show where the contractor made that smart adjustment to avoid an obstruction, and how the plumber moved a line to allow space for a support member. They capture the unscripted nature of construction.

There is something peculiarly attractive about that. The important message is that buildings are never some abstract theoretical construct but a result of people solving real-time problems. As-built drawings contain this history. They give that direct link between the idealized vision of design and physical manifestation in completed form.

Firms in architecture and engineering that invest in proper documentation pay homage to this very human side of building: real conditions, real challenges, real decisions molding the building. These are things they acknowledge.

As-Built Drawings vs Shop Drawings: What Freelancers and Service Providers Need to Know


In the world of design and construction, accuracy is an important quality. Technical drawings are what architects, engineers, component fabricators, and builders rely on to ensure accuracy and precision throughout any project. It also serves as a tool to help architects, engineers,and other professionals in the design and construction to help them visualize design concepts and communicate,and reconstruct design ideas efficiently. One of many construction documents required and produced in an architectural project are shop drawings and as-built drawings. These drawings play a big role in the component fabrication process and for project review purposes.

Cad Crowd is a leading platform providing the best architectural design companies with vetted and highly experienced shop and as-built drawing services. Let’s take a look at their differences.


🚀 Table of contents


Shop drawings

Shop drawings are technical documents that describe and define the design of pre-fabricated components in a project, such as buildings. It is usually encountered in architectural projects that are dedicated to the construction and installation of MEP (mechanical, electrical, and plumbing) systems. The key term “prefabricated” indicates that the components to be used are of a mass-produced kind, such as piping, precast concrete, trusses, fire protection, metal ductwork, appliances, and so forth.

MEP components need shop drawings, but you might encounter similar documents referring to some furniture products. This is true, but only if the clients want their furniture pieces constructed from prefabricated parts. In case they specifically ask for custom furniture built from milled components, what you need is a millwork drawing instead. Shop drawings are among the “must-haves” in most architectural projects, both residential and commercial, and now with the rise of prefab and modular construction technology, chances are you’ll see quite an increase in the shop drawing services sector, too.

One of the main points of shop drawings is to provide specifications and detailed illustrations of how the prefabricated components should be procured and assembled to build a specific component. Architects, designers, and engineers provide the design intent as a general visualization of the final product, but the actual shop drawings must be produced by the person in charge of sourcing and assembly. In a typical architectural design firm, this person could be the general contractor, subcontractor, or supplier. Shop drawings are not general blueprints; they’re tailored to highly specific systems, designs, or structures in a project. You’d have a better guarantee of accuracy when the drawings are produced by someone who actually understands the ins and outs of the components.

What to watch out for in a shop drawing

Shop drawing isn’t an artistic drawing; it is a visual representation of a construction plan proposed by either an architect or a designer. It’s pretty technical, filled with information on materials, dimensions, assembly instructions, etc. A shop drawing is practically a communication tool to bridge the gap between the design plan and the actual build. To minimize the possibility of miscommunication, a shop drawing needs to include important points as follows.

Points Purposes
Sections and elevations Every single component must be attached with dimension information, including height, length, width, diameter, and all other relevant measurements. It goes without saying that all the prefab components must fit precisely within the structure. A shop drawing also has to provide a view of the final product with the correct dimensions.
Dimensions A shop drawing service must specify the materials used for the prefabricated components. Additional details may include material grade, finish, type, and characteristics if needed.
Materials Certain prefabricated components may require further processing, such as cutting and shaping to match the defined design specifications, so you should be able to find the instructions in the shop drawings as well. In case the design uses a lot of raw materials that need some more elaborate treatments, you can use another document (fabrication drawing) to provide the instructions.
Detailed views When the design is complex enough that it requires small mechanisms or intricate details, the shop drawing provides enlarged views of those specific parts for clarity. Fabricators and installers refer to these “detailed views” to understand how the parts must be assembled.
Shaping Certain prefabricated components may require further processing, such as cutting and shaping to match the defined design specifications, so you should be able to find the instructions in the shop drawings as well. In case the design uses a lot of raw materials that need some more elaborate treatments, you can use another document (fabrication drawing) to provide the instruction.
Bill of materials (BOM) `Every single part and component you need for the design is listed in the BOM. Details include quantities, part numbers, specifications, and descriptions, and are essential for architectural planning and design companies.
Symbols Symbols are used to indicate welding locations, sizes, and types. In many cases, you can omit these symbols entirely if you have a separate fabrication drawing. Usually, this is used in a design where metal components need welding.
Assembly information An illustration of how the various components are assembled together. Some assemblies require different fasteners and connections, so you should make sure that all those details are clearly specified.
Finishing An instruction on how to apply the specific types of coating, textures, or colors.

As mentioned earlier, shop drawings are custom blueprints for specific designs. They’re quite elaborate, for they must convey all the information you need to fabricate components and build the assembly correctly.

Note about metal components: depending on the design, some metal components must be welded together or fabricated in a particular fashion before you can assemble them with all the other parts, for example, in piping or plumbing installation.

Some welding jobs are simple enough that you can actually include the instructions for them in the shop drawing. For anything more complex than the simplest kind of MIG welding, you’ll need to provide instructions in a separate technical document known as a fabrication drawing through metal design and fabrication services. The design drawing, especially between the shop drawing and fabrication drawing, can be different depending on the level of detail pertaining to the fabrication technique. Fabrication drawing provides details even up to the smallest information, welding tasks, and provides symbols and measurements for every section.

Why is shop drawing important

Not every construction project needs shop drawings, but it doesn’t change the fact that they’re important to ensure design accuracy and speed up project completion. Here are some key aspects in an architectural project where you might find shop drawings invaluable:

  • Coordination: Shop drawings are technical construction documents. As such, they function as a means of communication between all parties involved in the project, including but not limited to the architect, engineers, designers, contractors, subcontractors, fabricators, builders, and clients. Shop drawings are the points of reference when you’re coordinating the construction, keeping everyone on the same page.
  • Design visualization: architects, engineers, or designers produce the design intent – sketches that represent the basic geometry and dimensions of a design. Contractors or suppliers interpret those sketches and transform them into a much more detailed visualization, albeit a two-dimensional one.
  • Shop drawings provide a more detailed view that consists of specific dimensions, construction methods, materials, etc, compared to sketches. After finalizing shop drawings, the architectural design expert reviews for approval and checks if the interpretation is exactly as needed. In case there are inconsistencies between the drawings and the original plan, it must be revised. From there, it can only proceed to the construction/fabrication when all details are correct.
  • Guidance: If an architectural project involves a lot of designs, objects, or products constructed from prefab components, shop drawings must be treated as the only fabrication guidance. So long as the drawings have been approved by the architect or engineers in charge of the project, there’s almost no need to look for any other references.

There’s also quality control. Because shop drawings provide detailed fabrication guidance, you should be able to identify any mistakes in the finished work by cross-referencing it with the drawings, too. Assuming the project is large enough that the construction requires permits, shop drawings are also part of the documents to ensure compliance with local building codes; as in, you can’t acquire the permit or even apply for it without having shop drawings.

As-built drawings

A construction “as-built” drawing (also known as red-line drawing or record drawing) is the technical document that offers an overview of the final design. It might be used as a comparison tool to verify whether the end product comes out exactly as planned. Think of it as a blueprint compiled after the project concludes. Of course, the point is to showcase, in detail, how the project is actually built.

In an ideal world, every architectural project goes exactly as planned. But this is rarely, if ever, the case at all. An as-built drawing is submitted upon the completion of a project to reflect all the changes made during the construction process.

Such changes might include alterations in specifications, design geometry, locations of components, and basically all other works completed over the duration of the project and under the contract. Even the changes in shop drawings, for example, when prefab components need further treatments to fit the desired specifications, are also included in the as-built documents. Keep in mind that none of those modifications are made without approval from the architectural design and drafting firm and the clients.

But just because the drawings are submitted upon completion, it doesn’t necessarily mean they’re created as soon as the project ends. If you can allocate the time and budget, it’s best to schedule as-built surveys throughout the duration of the project. The surveys track how the construction progresses over time and create “partial” as-built drawings as they go. As long as there are no further modifications to the already “surveyed” sections of the project, you can simply compile the partial maps into one single drawing in the end. This makes the process much easier and quicker than having to retrace everything all over again.

What to include in an as-built drawing?

To make an as-built drawing as clear as possible, so that it may serve its purpose well as a review tool, you must include quite a lot of documents containing a lot of details. At the very least, these are the things you should see:

  • Record of changes in scale, but ideally, this should not be a problem as long as you use the same scale as the original blueprint.
  • Clear labels to identify changes, instead of vague phrases like similar to, equal to, taller, bigger, or any potentially ambiguous terms, without mentioning additional details.
  • All records of changes in sizing, dimensions, locations, fabrications, installations, assemblies, materials, textures, and so on.
  • Specific dates when every single one of those changes occurs.
  • Notes on unexpected challenges encountered during the project, and the solutions implemented to solve them.
  • Notes about changes proposed during the final inspection.
  • Shop drawings, original blueprints, and appendices.

As-built drawings are usually signed by the architect associated with the original blueprint, and shop drawings are created by contractors and suppliers during their contract with the project. In case you hire your own architect, their role is to record all the changes made to the design, as they are the most qualified to do the task because of their familiarity with the intended design.

If you’re running a small architectural firm without in-house drafters, you can always outsource the task to third-party CAD service providers or freelancers. However, since the architects have the final say to approve the design, it doesn’t really matter who actually produces it. In case there are mistakes in the drawings, you’re allowed to ask for revisions, too. The same thing applies to shop drawings.

Why should contractors care about as-built drawings?

Although submitting as-built drawings is not always mandatory in every project, the documents serve as important components of any finished project. They’re the most accurate representation of what was actually built in the first place, and will be indispensable references when you need to modify, expand, renovate, and build on top of the old work.

If you’re a general contractor, you might be wondering why you should prioritize producing and submitting an as-built at the end of a project. As a matter of fact, you shouldn’t be focusing on creating an as-built throughout the project at all; instead, you should strive to maintain or improve your work and quality to be reflected in the as-built.

The truth of the matter is that as-built drawings can’t really affect the construction at all. But it can do wonders for your reputation as a company and bring more businesses in the future. As for subcontractors, as-built drawings are especially important if you’re hired to do a renovation and a maintenance project. Once again, the as-built will be your most dependable document of reference to improve your chances of completing the job with great success.

Finally, as-built drawings are proof that the architects, contractors, engineering design firms, designers, subcontractors, and fabricators have moved on from the project. They’ve done what they’re hired to do, and you can always take a closer look at what they made from the submitted and approved as-built drawings.
