What is an As-Built Septic Plan?

What is an As-Built Septic Plan?

Modern construction requires not only the participation of one or more contractors and the property owner but also the county. Most construction projects in Massachusetts (and other states) require building permits. For permits to be granted, you must provide supporting documentation of the project, including building plans. Once construction begins, there may be deviations to the plan due to a number of factors. During the construction process, the original build plans get modified as changes occur. These modified plans become the “as-built” or Record Drawing. These are especially important for underground construction, such as septic records.

The need 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. You could have 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. In order to get the appropriate permits to start construction, the contractor needs these record drawings to create the new building plans. 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. The contractor makes these changes to keep the building plans consistent with the reality of the project. 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.
  • Obstructions that have not been previously documented should be recorded.
  • When working on an existing sheet or adding an additional one, size and scale should be kept uniform.
  • Even if there are no changes to the original documents, all as-built plans need to be dated on each page.
  • Provide this document electronically to ease transmission and archiving.
