Self Perform Work


West Coast Air is very proud of the fact that most of our 118 (current) employees have been with us for 15+ years. In the up and down world of construction we think that really means a lot. The value of West Coast Air self-performing work is shown in our knowledge of sequencing construction. The speed and efficiency that West Coast Air can perform multiple tasks, limits the downtime of your facility during construction. This speed and efficiency is also a benefit when delays are faced by unforeseen changes, which commonly occur during construction. Above all, we know each other, have well established roles which each of us fulfill to assure the project remains on track and finishes with all of the Owner’s expectations being met.
