Alpha & Omega Group provided engineering services to Wake County to improve stormwater drainage issues at convenience center sites 1, 4, 5, 8, 9, and 10 and installed reinforced concrete pads for storing compactor boxes. For site 4, we designed wall extensions and produced construction drawings to raise the height of existing retaining walls as a noise control measure.

 A&O’s scope included a visit to each facility to collect field measurements. We coordinated with a surveyor for a topographic survey of sites 4,8, and 10. We produced a grading plan, an erosion control plan, and a site plan for each location and provided pertinent construction details and specifications. Improvements for site 8 involved the removal of all asphalt to regrade and compact subgrade, installation of new curb and gutters, and repaving the site.

A&O provided an engineer’s opinion of construction costs, assisted with bidding, performed construction administration, and provided as-built record plans. Ω
