BACKGROUND

ACRP Report 102: Guidance for Estimating Construction Emissions and the Airport Construction Emissions Inventory Tool (ACEIT) help airports and stakeholders better understand and quantify airport construction emissions and bring consistency to airport construction emissions inventories.  The ACEIT enables users to rely on default information about the construction process for typical airport projects.  However, since the release of the guidebook and tool in 2014, both on-airport construction practices and modeling techniques have changed.  For example, the U.S. EPA emissions models, NONROAD and MOVES, were combined into MOVES; emissions from typical construction projects have decreased due to improved equipment and practices; federal and state regulations have changed; and inventory methods have improved.  In addition, users have identified the need for the tool to have more reliable performance and flexibility to accommodate unique study parameters.  These changes need to be incorporated into the tool and a user manual to ensure they provide the most helpful guidelines and ensure modeling efficiency and representativeness.

OBJECTIVE

The objective of this research is to develop ACEIT Version 2.0 and an accompanying user manual to update and improve the tool’s functionality and usability.
