About this opportunity
The U.S. Army Corps of Engineers, Norfolk Engineering District, is seeking industry input through this sources sought notice regarding the beneficial use of dredged sediments for shoreline stabilization at Tangier Island, Virginia. The project proposes to utilize approximately 100,000 cubic yards of shoaled material from the federal navigation channel by placing it within geotextile tubes rather than disposing of it offshore or along the shoreline. The primary objective is to evaluate the feasibility of this approach, with particular focus on whether geotextile tubes can be effectively constructed using fine-grained sediment material and whether sufficient material volume exists to support the proposed design. Respondents are requested to address specific geotechnical and coastal engineering questions outlined in the survey, including construction feasibility, anticipated material losses, shrinkage factors, dewatering timelines, and consolidation periods required to achieve design strength. The due date for responses is March 26, 2026, and interested parties should note that this is a sources sought notice only and does not constitute a formal request for proposals.
This opportunity carries no set-aside designation and does not identify any incumbent contractors or current award values. The project is classified under NAICS code 237990 (Other Heavy and Civil Engineering Construction) and PSC code Y1KF (Construction of Dredging Facilities), indicating the heavy civil engineering nature of the work. The geotechnical baseline data indicates highly variable sediment composition across the navigation channel, with fine-grained materials dominating eastern portions and coarser sand deposits present on the western side beyond the jetty, as documented through ten vibracore samples collected in 2024. The coastal summary documents significant erosion challenges driven by nor'easters and tropical storms, with a 1-year return period significant wave height of 5.59 feet referenced to 2025 mean lower low water conditions. While no specific budget or timeline has been announced, the sources sought process will inform the government's development of formal procurement solicitation documents for this beneficial use project.
Notice text
THIS IS A SOURCES SOUGHT NOTICE ONLY. THIS IS NOT A REQUEST FOR PROPOSALS. ALL AVAILABLE INFORMATION IS INCLUDED IN THIS NOTICE.
Purpose:
USACE is evaluating the beneficial use of shoaled sediments within the Tangier Island navigation channel. The volume of shoaled material varies depending on dredging frequency; however, the most recent survey indicates that approximately 100,000 cubic yards are currently present within the channel. Instead of disposing of this material offshore or placing it directly along the shoreline, USACE proposes to use it for shoreline stabilization by placing it within geotextile tubes (i.e. Geotubes®). Additional details regarding sediment characteristics are provided in the Geotechnical Summary, and design information is included in the Coastal Summary sections.
The attached document contains both the Geotechnical Summary and the Coastal Summary. Please answer the survey questions below using the data from this document.
Industry Survey:
Given the details provided in the attached document, is it feasible to construct geotextile tubes given the fine grained nature of the soil and is there enough material available for the proposed design?
Geotechnical Summary Survey
- Based on the fine-grained nature of the dredge material, it is feasible to fill geotextile tubes effectively?
- What are the anticipated losses during the dredging and infilling process of the geotextile tubes based on our geotechnical data?
- What is the expected "shrinkage" factor? Specifically, for every cubic yard of material dredged, what is the anticipated final, consolidated volume of material inside the tube?
- What are the anticipated dewatering times for the geotextile tubes, particularly when filled with material having a high percentage of fines?
- How long is the anticipated dewatering and consolidation period to achieve the required strength for the design?
- Should additional geotechnical data be collected to better inform your analysis?
Coastal Summary Survey
- What are the recommended wave heights for single and stacked systems?
- How does the product perform during elevated water levels and overtopping conditions?
- What anchoring or toe stabilization measures are recommended in the sandy sediment?
- How deep do the anchors go to stabilize the geotextile tubes and is it pertinent to know the type of material the anchors are founded in? Surface grab samples indicate >98% sand.
- How is scour addressed during storm events that produce medium-high wave energy?
- Can the geotubes be placed in the nearshore (-3 ft MLLW), or do they need to be placed on the beach?
This Sources Sought Synopsis should not be construed in any manner to be an obligation on the part of the U.S. Army Corps of Engineers–Norfolk District to issue a contract or result in any claim for reimbursement of costs for any effort you expand responding to this request. No solicitation is currently available. The Government will utilize this information in determining an acquisition strategy.
Please submit responses to the above questions via email to Caleb Bookout at brian.c.bookout@usace.army.mil, copying Tiffany N. Kirtsey at tiffany.n.kirtsey@usace.army.mil. Responses must be submitted no later than Close of Business 25 March 2026.
