Morrison-Shipley provided surveying, design, and construction phase services for Airfield Drainage Improvements at the Fort Smith Regional Airport. In order to facilitate construction of the Airport's new passenger terminal facility, significant drainage improvements were required to relocate existing airfield drainage ways traversing the proposed site. Because a portion of this work was completed within established FEMA floodplains & floodways, Morrison-Shipley was required to perform extensive flood studies, including remapping of the FIRM, to properly site the floor elevation of the terminal building.
In total, this project constructed approximately 1.2 miles of new earthen drainage ditches consisting of approximately 57,000 CY of excavation. Also included in the construction work were two triple 9’ x 5’ concrete box culverts and 750’ of gabion-lined channels. Incidental to this work was the mitigation and relocation of existing wetlands areas on the Airport to an off-site location.
This project was completed on budget at a cost of $1.3 million and within the contracted nine-month construction period.
