As Built Document: Everything You Need To Know

Welcome to the world of construction and design! Ever wondered how buildings go from blueprints to reality? That's where "As-Built Documents" come into play. Let's dive into the basics and unravel everything you need to know about As-Built Documents in a way that's easy to understand!

What is an As Built Document?

An As Built Document is a record that shows how a construction project or infrastructure looks and functions after it's been completed. It's like a final report that documents the actual, real-world details of what was built, as opposed to the initial plans.

Imagine you're building a house. The original blueprint or plan shows where every room, window, and door should be. However, during construction, there might be changes or adjustments made based on practical considerations or unforeseen issues.

Once the house is finished, an As-Built Document would be created. It includes updated drawings or descriptions that reflect what was actually built, not just what was initially planned. This document is useful for future reference, renovations, or maintenance because it accurately represents the final product.



Who Truly Needs As Built Document?

Facility Managers and Owners

Why? Imagine you buy a new house. You'd want to know where the water pipes are, where the electrical wires run, and how the heating and cooling systems are set up, right? As-built documentation is like the instruction manual for your building.

For example, if a pipe starts leaking, the facility manager can quickly look at the as-built drawings to find out where that specific pipe is and how to fix it without tearing down walls or floors.

General Contractors

Think of the general contractor as the conductor of an orchestra. They need to make sure everyone is on the same page during the construction process. As-built documents help them compare what was planned with what was actually built.

For instance, if a wall was supposed to be a certain length, the general contractor can check the as-built drawings to confirm it was built correctly. It's like a final check to ensure everything aligns with the original plan.

Service Providers

These are the folks who maintain and repair different systems within a building—plumbers, electricians, HVAC technicians, etc. They need to know the layout of these systems to do their job efficiently.

For example, if an air conditioning unit malfunctions, the service provider can refer to the as-built documents to understand how the ductwork is set up and locate the problem without unnecessary guesswork.

Future Contractors

Imagine someone wants to add a new room or upgrade the electrical system years after the building is constructed. The new contractors need to understand the existing structure, and as-built documentation is their guide.

If a new contractor wants to install solar panels on the roof, they can refer to the as-built drawings to ensure they're not interfering with existing structures or systems.



The Importance of Accuracy in As Built Document

Precision means being very accurate and careful in how you record and show things. Imagine you're telling a friend how to build a LEGO castle. If you're not precise in your instructions, they might end up with a wonky tower or missing pieces.

In the same way, if as-built documentation isn't precise, it can lead to confusion and mistakes. For example, if someone needs to fix a problem in a building or figure out how a machine works, they rely on the as-built documentation to guide them. If the information is not accurate or clear, it could cause errors, delays, or even safety issues.

Being precise in as-built documentation is like giving someone the perfect set of instructions to follow. It helps everyone involved - whether it's builders, repair people, or maintenance crews - do their jobs correctly and efficiently. So, just like in building a LEGO castle, precision in as-built documentation is the key to making sure everything fits together perfectly.

Benefits of As Built Document

A Snapshot of Reality

Think of As-Built Documentation as a photo album for your project. When the construction dust settles, and the last nail is hammered in, you get a comprehensive record of what was actually built. This is incredibly useful for future reference, maintenance, and any future modifications or expansions.

Avoiding Surprises

Ever bought furniture only to find out it doesn't fit through the door? As-Built Documentation helps avoid these surprises in construction. By accurately reflecting the final product, it ensures that everyone involved in the project is on the same page. No more unexpected hurdles or costly changes down the road.

Troubleshooting Made Easy

When something goes wrong, finding the issue is much easier with As-Built Documentation. It's like having a superhero guide that helps identify and fix problems efficiently. Whether it's a leaky pipe or an electrical hiccup, having an accurate record of the building's structure makes troubleshooting a breeze.

Cost Savings

Imagine saving money by avoiding unnecessary rework or modifications. As-Built Documentation does just that. It minimizes the chances of errors by providing a clear picture of what was intended versus what was built. This not only saves money but also ensures that resources are used efficiently.



Difference Between AS Built Document and Detailed Drawing Document


Detailed Drawings

As-Built Documents


Created before construction

Created after construction


Idealistic, representing the planned outcome

Realistic, reflecting actual construction


Guide construction and ensure everyone's on the same page

Document final state for future reference and maintenance


Architect's blueprint

Contractor's marked-up drawings with notes about changes
