lthough airplane hangars have been around since the dawn of flight, the hangars of today are more complicated and costly than ever before. Numerous technological advancements, shortened project schedule requirements, and increased regulatory oversight have made the management of a success- ful hangar project much more demanding. A
The greatest challenge faced by a new hangar project team (see “Assembling the Project Team,” p. 12) is to properly manage schedule, cost, and quality throughout the planning, design, and con- struction phases of the hangar project. The key to successfully meeting this challenge is to carefully plan the hangar before moving to the design and construction phases of the project (see “Planning Considerations,” p. 12).
The category of airline objectives encompasses the specific maintenance and operational requirements of the new airplane hangar facility. These requirements must be identified early in the project to ensure the hangar will support the needs of the airline. Specifically, the hangar project team should
Identify the current and long-term projected airplane fleet, including the number of airplanes that will use the facility, the annual use of airplanes, and maintenance- hour requirements.
Identify the types of maintenance to be performed, the number of components annually serviced, and estimated workload projections including room and space require- ments. In addition, the team should identify specific shop-equipment needs to determine the building’s mechanical and electrical service requirements. Specific hangar functions to be reviewed are listed in table 1.
1 ABILITY TO INFLUENCE FINAL COST OVER PROJECT LIFE A properly engineered project plan
allows all other aspects of the project to proceed as simply as possible, while minimizing complicated and costly factors such as multiple design and construction packages, bid escala- tion due to uncertainty, high change rates, estimated-cost construction contracts, and large project manage- ment staffs. The planning phase yields the highest opportunity for saving cost while requiring relatively insignificant project funding to perform (fig. 1).
A good hangar project plan specifi– cally addresses the following:
