The National Park Service seeks design-build services to stabilize the Cuyahoga riverbank along the Towpath Trail near Mile Marker 20 South at Cuyahoga Valley National Park in Ohio, with proposals due August 13, 2026. This is a total small business set-aside under a two-phase competitive design-build selection process. Phase 1 evaluates technical approach, specialized experience, past performance, and bonding capacity; up to three offerors advance to Phase 2 for price and management evaluation.

Place of performance is Brecksville, Ohio, along the Cuyahoga River. The contractor must stabilize approximately 800 linear feet of eroding riverbank using rock toe placement, bioengineered brush mattress, live staking with native vegetation, and slope reconstruction at a maximum 2.5:1 gradient. Work includes site access via Stanford Road with material staging, timber mat construction crossings, and full site remediation. The contractor bears responsibility for all geotechnical and hydraulic analyses, topographic and bathymetric surveys, global stability analysis, and permitting including USACE Section 404/10, Ohio EPA Section 401, and USCG Notice to Mariners.

Estimated construction cost is $1.4 million on a firm-fixed-price basis. Performance and payment bonds at 100 percent of contract price are required within 10 days of award. The contractor must begin work within 10 days of notice to proceed and complete all work within 260 calendar days. Design Development Documents are due 30 days after notice to proceed, with progressive construction document submittals at specified intervals.

Distinctive requirements include compliance with Davis-Bacon prevailing wage rates for Ohio heavy construction, tree-cutting restrictions (April 1 to September 30) for Indiana bat and Northern long-eared bat protection, in-water work restrictions (April 15 to June 30 unless waived by USFWS), and bald eagle nesting protections. The contractor must obtain all federal permits and submit extensive pre-construction documentation including Critical Path Method scheduling, accident prevention plan, environmental management plan, and stormwater pollution prevention plan. Contract modifications are limited to maximum 10% overhead and 8.25% profit for contractor self-performed work, with 25% total aggregate markup across all tiers. The NAICS code is 237990 (Other Heavy and Civil Engineering Construction); PSC is Y1QA.
