Topics Covered:

  • Overview of construction plan sets
  • Understanding the cover page and project details
  • Key components of the sheet list table
  • Identifying grading plans, drainage layouts, and utilities
  • Locating survey control information
  • Document control and ensuring access to updated plans


Every construction project begins with a set of plans that outline all aspects of the work to be performed. While plan sets vary from project to project based on the designer, engineering firm, or client, there are consistent elements that can be found in almost every plan set. Understanding these standard components allows for a more efficient and accurate workflow.

The Cover Page and Project Overview

The first sheet in any plan set is typically the cover page, which provides essential project details. This page includes the project name, size, general location, and often a site map indicating where the project is located in relation to surrounding areas. The cover page serves as an introduction to the entire project and provides a high-level overview before diving into detailed plans.

The Sheet List Table

A key feature of most plan sets is the sheet list table, which organizes all included drawings and provides a roadmap for navigating the document. Typical sections in a sheet list include:

  • General Notes: A section filled with important textual information regarding construction guidelines, codes, and specifications.
  • Final Plat: A detailed depiction of property lines and boundaries.
  • Demolition Plans: Outlines structures or elements that need to be removed before new construction begins.
  • Basic Layouts and Grading Plans: Shows elevation changes and contour lines to indicate the final grading design.
  • Existing Drainage and Utility Layouts: Provides insight into current site conditions and where water is expected to flow.
  • Erosion Control and Environmental Considerations: Details measures required to prevent soil erosion and maintain compliance with environmental regulations.
  • Concrete Paving and Typical Details: Includes standard construction details related to pavement, sidewalks, and site structures.

Finding Survey Control Information

One crucial element that should always be checked in a plan set is the survey control page or equivalent section. This page references the coordinate system and specific values used throughout the project. Some plan sets prominently feature this information near the beginning, while others embed it within different sections, requiring closer examination. Survey control ensures that all measurements and locations within the plan set align with real-world coordinates, aiding in accurate site work.

Document Control and Plan Revisions

Access to up-to-date plans is vital for ensuring that construction and surveying work aligns with the latest project requirements. Plan sets are often distributed through cloud-based services or email, making it important to check for the most recent versions. Large, long-term projects frequently undergo revisions, requiring all team members to verify they are working with the latest set of plans.

Many job sites have a document control manager, responsible for maintaining and distributing updated plans. This role ensures that outdated information does not lead to errors or misaligned deliverables.

Importance of Staying Current with Plan Sets

Using outdated plans can result in costly mistakes, including:

  • Incorrect material orders
  • Misaligned construction elements
  • Regulatory non-compliance
  • Project delays and additional rework

To avoid these issues, always verify plan versioning and maintain communication with project managers and document control personnel.
