Body
BACKGROUND
The City of Dallas currently owns property adjacent to the Kay Bailey Hutchison Convention Center (Convention Center) known as Parking Lot “E”. The Convention Center is planned to undergo an expansion and anticipates additional development within Parking Lot “E”. The Dallas Water Utilities Department has an existing 51-inch diameter wastewater interceptor built in 1914 that crosses through Parking Lot “E” which will significantly hinder future development of the area. The interceptor will be rerouted along Reunion Boulevard and down Sports Street to connect into the existing 90-inch horseshoe interceptor. In addition to the rerouting of the 51-inch diameter interceptor, it is necessary to construct a new 12-inch wastewater main to serve the Convention Center along Hotel Street and replace a 48-inch and 54-inch diameter wastewater interceptor along the southern edge of Lot “E”.
On October 26, 2022, the City Council authorized a construction services contract with John Burns Construction Company of Texas, LLC for the installation of water and wastewater main improvements to facilitate future improvements to the Kay Bailey Hutchison Convention Center and also allow the expansion of Interstate Highway (IH)-30 from IH-35 to IH-45 by the Texas Department of Transportation (TxDOT).
The original design assumed that the wastewater flow in the existing horseshoe interceptor could be diverted during construction with by-pass pumping, utilizing manhole structures. However, during construction the contractor was unable to provide by-pass pumping due to a narrow easement with inadequate space for the bypass pumping setup. An engineered solution was prepared to resolve the problem, requiring the contractor to install two new junction structures with specialized structural designs and make in service connections to the existing wastewater interceptor avoiding bypass pumping. In addition, while installing a 12-inch diameter wastewater main in Hotel Street, the contractor encountered unexpected structurally poor soils that required substantially more backfill material and paving restoration than originally anticipated.
This action will authorize Change Order No. 1 in the construction services contract with John Burns Construction Company of Texas, LLC for the construction of two cast-in-place junction boxes to connect a new 48-inch diameter wastewater main to the existing horseshoe interceptor and for additional pavement and backfill material quantities at Hotel Street.
