Charlotte Douglas International Airport Central Energy Plant

Project Summary

In 2019 Charlotte City Council approved a $585M project to renovate the terminal lobby at Charlotte Douglas International Airport (CLT) in North Carolina. Known as the Terminal Lobby Expansion, the project is a part of the Destination CLT program which will entail an overall investment of $2.5B to $3.1B. This is one of the largest ongoing aviation construction projects in the southeast. A significant part of this development program is the new construction of the Central Energy Plant (CEP). This building will offer mechanical space for the terminal lobby expansion project. It will supply chilled and hot water for the air conditioning of the terminal lobby via an underground utility corridor. The CEP is being built on an existing parking area with a 39,862 square-foot footprint.  The CEP will have two levels. The first level contains emergency and normal power rooms, a chiller room, a boiler room, and a water treatment room. The second level is a mezzanine with an equipment platform. The roof contains cooling towers with space for future cooling towers. There is a 275Kw generator outside of the CEP to the south. Rosendin is responsible for lighting, power (including medium voltage switchgear), grounding, and lightning protection.

Case Study

The project team connected with the BIM department to enhance the ongoing 3D model efforts to a 5D model. Options and cost were evaluated. An agreement was made that the project team would fund up to $2,000 and the BIM department would fund any costs beyond that.

At the time of initiating the 5D model, the 3D model was approximately 95% complete.

5/20/2020 – 6/17/2020 Weekly Meetings to Review Input Data

Input Data Delivery:
The project team provides a break-out based on the construction activities, start and finish dates that were previously shared with the GC on 5/5/2020, as an effort to help create an overall project schedule. The activities were labeled with ID numbers which were also reflected on accompanying drawings to visualize the extend for the modeler. The modeler also received a cost-plus margin for each activity. That financial information was extracted mostly from the schedule of values (SOV) that had been established for monthly progress billing with for GC. The SOV includes input from subcontractors and vendor break-out.

An AVI video file of a moving presentation of the 3D model, while presenting a moving timeline showing the date at any given point in time of the video at the top of the picture. The Dollar amounts are reflected via a steady table on the side of the picture. The Dollars are not linked to the moving timeline that is moving along at the top of the picture. The video shows the construction progress of UG duct banks, manholes, feeder installation, site lighting, interior lighting, equipment placing, etc.

The development of the 5D model went faster and less costly than expected. The efforts helped the BIM department to learn about the software capabilities and implementation. In order to use the 5D model for productivity and progress tracking, additional dollar breakdowns would need to be developed, allocated to the schedule, and inserted.
