Sigma provided Civil Engineering Construction Support Services for the Duck Creek Channel project between Mountain Vista Street and Green Valley Parkway. 

The scope of work included a site visit to investigate existing conditions and to document and review proposed improvement areas. Sigma assisted with the preparation of construction drawings and calculations for perforated underdrains required along the length of the channel, the preparation of structural details to tie the proposed concrete channel to the existing concrete channel at both ends of the project, and the preparation of structural details for concrete form design along the curved areas of the channel.

Sigma also assisted the project contractor with permit preparation.
