What is an As-Built Septic Plan?

Engineering Drawings and tools on a tableModern construction requires not only the participation of one or more contractors and the property owner but also the county. Building permits are required for construction and to be granted must be supported with documentation, including building plans. Once construction begins, there may be deviations to the plan due to a number of factors. An “as-built” plan or Record Drawing are the building plans modified to account for any changes made during the construction process. These are especially important for underground construction, such as septic records.

The Needs for As-Built Septic Drawings

As mentioned before, it’s vital to know what is underneath before you start digging in your yard. Even if you have the building plans for your septic system, if they are not the as-built plan the position, orientation, and structure of the actual septic system could differ significantly. This leads to issues when digging in the yard, and especially when the septic system needs maintenance or complete replacement. After installation of any septic, it’s vital to make sure that the changes are recorded and submitted to the county office.

Getting Your As-Built Septic Drawing

If you or a hired contractor is planning on repairing or replacing your septic systems, you’ll need to pick up the as-built plans for the septic system before work begins. In our city of Marlborough, as-built plans are submitted and stored by the Engineer Division of the Department of Public Works. It may differ depending on your city and county, with some having searchable online databases. These record drawings are needed by the contractor to create the new building plans, which are required for getting the appropriate permits to start construction. When you decide to repair or replace the septic system, getting these drawings should be one of the first steps.

Reading and Writing an As-Built Septic Plan

During the construction process, the contractor or management office will be constantly updating the as-built plan as the building plans meet the reality of the project and changes have to be made. Here are a few basic tips to reading, and even editing them yourselves.

  • Plans may include approximate measurements, which should be replaced with measured values.
  • Common changes to note are differences from the original plans in the method of erection and installation, sizing and dimension, and the material and fabrication.
  • Record all found obstructions that have not been previously documented.
  • When working on an existing sheet or adding an additional one, size and scale should be kept uniform.
  • All as-built plans need to be dated on each page, even if there are no changes to the original documents.
  • This document should be provided as an electronic copy for ease of transmission and archiving.
