TxDOT Aviation, Georgetown Municipal Airport - Engineering /Design Services

Klotz Associates Austin Office has been selected by the Aviation Division of the Texas Department of Transportation (TxDOT) and the City of Georgetown to perform Engineering / DesignServices for a project at Georgetown Municipal Airport. The airport is considered to be an extremely important reliever facility within the Central Texas airport system. The project will include improving the Runway Safety Areas, rehabilitating the corporate taxiway and hangar access aprons, widening a taxilane and installing obstruction lighting. Estimated construction cost is $2 million.

Houston Airport System, George Bush Intercontinental Airport – Terminal B and C North Ramp Extension
This project included aircraft pavement design, geometric layout, grading, and pavement markings for pavement expansion adjacent to Terminals ‘B’ and ‘C’ at IAH.  Designs and phasing plans were also considerate of detailed construction sequencing associated with work areas within the terminal apron.  Project expanded Taxiway ‘WC’ at the fuel triangle and taxiway fillet expansion at Taxiways ‘WB’, ‘WC’, and ‘WE’.  Project also included paving the infield areas at Taxiway ‘NB’, ‘NO’, and ‘NK’ at the edge of the north apron.  The project also added asphalt shoulders at five infield islands.  HVJ Associates was a team member for this project, performing the geotechnical investigation.  Grading design for the project included six infield islands plus new pavement extended from the north apron at Terminal C.  Services during design included a full range of engineering design services including preparation of project plans, specifications, and estimates.  Construction sequencing included details to minimize disruption to airport operations so that no terminal gates needed to be closed during construction

Houston Airport System, George Bush Intercontinental Airport - Rehabilitation of Runway 15L-33R

The scope of this ongoing project includes design of concrete pavement replacement on 3,000 feet of runway as well as the bonded concrete overlay of 5,000 feet of existing concrete runway and connecting taxiways. Klotz Associates performed an analysis to determine the need for concrete overlay by using non-destructive pavement analysis and finite-element computation of pavement performance under anticipated aircraft traffic. This allowed determination of required pavement thicknesses and further crack-propagation analysis for confirmation of overlay thickness to ensure against pavement shoving. During design of the pavement overlay, the firm determined that additional requirements must be specified for installation of the overlay to ensure a full bonding of the overlay to the existing pavement.

Scholes International Airport
For this project Klotz Associates strengthened the taxiway parallel to the primary north-south runway, which needed improvements to the GA apron areas. Also, the taxiways to the T-hangars were in need of replacement. The firm completed an investigation of the 40-to-50-year-old pavement on the taxiway and executed design for its total rehabilitation. Klotz Associates also developed construction plans, which included overlay and slurry seal of all GA pavement areas. VASI on Runway 17 was replaced with PAPI-4. Work on the project also included various signage improvements and development of a detailed construction phasing plan that would not shut down FBO (fixed-base operation) or GA operations. Klotz Associates also prepared the scope of work for surveying and for geotechnical services and secured fee proposals for it. The firm also prepared a fee proposal for all services and submitted it for review.
