Functional Part: Driveway

Name

Driveway

Identifier

fp_driveway

Overview

This functional part defines the requirements for modeling and exchanging driveway connection information in a highway BIM environment. Driveways represent access connections between public roadways and adjacent properties, serving residential, commercial, or agricultural land uses. These access points require careful coordination for sight distance, spacing, and access management compliance.

Results

Purpose

The purpose of this functional part is to standardize the exchange of driveway information between BIM tools and permitting systems, enabling accurate location documentation for right-of-way coordination, integration with access management policies and permit systems, sight distance verification for safe ingress/egress, coordination with drainage and utility crossings, and asset tracking for maintenance and permit compliance.

Examples

Example 1: Commercial Driveway Access Permit

Use Case: Document approved commercial driveway location and dimensions for permit compliance and construction.

Scenario: A new commercial development requires two access driveways on a state highway. The access management permit specifies driveway spacing, width, and sight distance requirements that must be verified in the design model.

Data Flow:

  1. Designer models driveway locations per approved access permit
  2. Driveway data exported with station location, width, and permit references
  3. State DOT imports data to verify compliance with access management policy
  4. Contractor receives approved driveway locations for construction

Key Information Exchanged:

  • Driveway type: “Commercial (two-way)”
  • Width: 36 feet (per permit requirements)
  • Station: 125+42 (south driveway), 126+15 (north driveway)
  • Spacing: 73 feet (meets minimum 75-foot spacing with exception)
  • Permit number: “AP-2025-08-442”
