81 April 12, 2017 Lysaght & Associates, PA 120 St. Mary s Street Raleigh, North Carolina Attn: Re: Mr. Mark Blankinship Evaluation of Foundation Bearing Conditions Greenway Pedestrian Bridge Replacement Riverwood Subdivision, Clayton, North Carolina GeoTechnologies Project No EA Dear Mr. Blankinship: GeoTechnologies, Inc. is pleased to submit this letter for the above referenced project. We understand that the existing post supported greenway pedestrian bridge located at the end of Charleston Drive has collapsed due to flooding from hurricane Matthew and will be replaced with a new, single-span steel bridge supported on a shallow foundation. The specific details on the foundations including size and depth have not been determined at this time. An evaluation of the subgrade soils in the general location of the two proposed foundations was performed on April 11, 2017 by Mark Potratz, PE. The evaluation of the subgrade soils included probing the soils with a ½" diameter steel probe rod and performing hand auger borings with DCP testing. Based upon the evaluation, the subgrade soils in the location of the north end bent generally consisted of firm silty and clayey sands about 2 feet below existing grade suitable for a design bearing pressure of 2,000 psf. The soils at this location exhibited DCP values between 5 and 10 blows per increment. At the south end bent location, soft fill soils were encountered to about 6 feet below existing grade overlying firm silty sands with gravel. At this location we recommend that the soft fill be removed to the firm silty sands at about 6 feet below grade. If scour is not an issue due to the distance of the footing from the centerline of the creek then the excavation can be backfilled with washed stone. If scour is a concern, the excavation should be backfilled with lean concrete. Once the repairs are made at the south end bent, the footing can also be designed for an allowable bearing pressure of 2,000 psf. After excavation of the end bent foundations, we recommend that GeoTechnologies perform a follow-up foundation evaluation to confirm our recommendations or provide additional recommendations as needed. GeoTechnologies, Inc. appreciates the opportunity to have provided you with our services on this phase of the project. Please contact us if you should have questions regarding this letter or if we may be of any further assistance. Sincerely, GeoTechnologies, Inc. Mark R. Potratz, PE NC Registration No
