Marietta Road Bridge Replacement Over CSX - Phase I

The City of Atlanta is soliciting proposals via Qualification Based Selection under the Brooks Act for replacement of the Marietta Road Bridge over CSX railroad — Phase I submissions due October 12, 2026 at 2:00 p.m. EST, with Phase II due November 20, 2026. The City applies a Small Business Enterprise diversity goal of 25 percent under NAICS 541310 (Architectural Services) and 541330 (Engineering Services).

The scope encompasses replacement of a weight-limited 1971 concrete box beam bridge (currently signed 10 tons, 423.5 feet long, 5 spans) with a new structure, pavement, curb and gutter, and continuous 5-foot sidewalks on both sides; the project also includes a continuous standard 5-foot sidewalk along Marietta Road from south of the bridge to Perry Boulevard/West Marietta Street (approximately 0.8 miles). The Prime Consultant must hold Georgia Department of Transportation prequalification in Roadway Design (3.02) and Utility Coordination/Railroad Coordination (3.10).

This is a two-phase QBS process with no cost submission for either phase; offerors submit $0.01 as a line item, with cost negotiation following selection. Phase I evaluation weights 30 percent to Project Manager, Key Team Leader(s), and Prime's Experience and Qualifications, and 20 percent to Resources and Workload Capacity. Phase II evaluation allocates 40 percent to Technical Approach and Suitability and 10 percent to Past Performance. Three to five shortlisted proponents advance from Phase I to Phase II. Submissions are made via ATLCloud.

Required insurance includes $1 million commercial general liability, $1 million automobile liability, $3 million excess/umbrella coverage, and $2 million professional liability. All compliance documentation, Georgia Security and Immigration Compliance Act Affidavits, and Office of Contract Compliance forms demonstrating diversity compliance must be submitted within five business days of award. Supplier questions for Phase I were due September 18, 2026; Phase II questions are due October 23, 2026.
