Kenall was responsible for drainage system design and CADD services associated with the Taxiway Drainage Rehabilitation Program at George Bush Houston Intercontinental Airport. The overall program focused on the widening of taxiways SF, SG, SH, SJ, SK, SA, and SB.

Our role encompassed redesigning the existing culverts to raise the head walls and wing walls and developing the grading plan around the drainage ditches to establish new side slopes after these taxiways were widened.
