SEA internal "operational" audit of noise insulation program - January 2013-March 2019

This internal audit reviews Sea-Tac Airport's (SEA) Noise Insulation Program from January 2013 to March 2019, comparing its construction and management practices to those of other airports. The audit finds recurring problems with inconsistent workmanship, weak internal accountability, and poor communication between management, contractors, and homeowners dating back to the program's origins in 1985. Key recommendations emphasize the need for more frequent oversight, stronger payment controls, and clearer reporting standards to improve program efficiency and homeowner satisfaction.

Notes

An internal operational audit reviewing Sea-Tac Airport’s Noise Insulation Program from January 2013 through March 2019, comparing SEA’s Job Order Contracting (JOC) approach to KCIA’s bundled bidding method. The audit identifies significant weaknesses in SEA’s program including lack of internal accountability, inadequate payment controls, infrequent oversight meetings, and poor communication with contractors and homeowners. The document contrasts SEA’s slower pace (401 homes in three years) with KCIA’s more efficient program (609 homes in six years) and traces SEA’s communication and leadership failures back to its original 1985 program.
