Engineering Services for the Earles Lane Culvert Replacement Project

Radnor Township, Pennsylvania is soliciting proposals from qualified professional engineering firms for engineering, design, permitting, and bid-phase services to replace the Earles Lane culvert over Saw Mill Run, with proposals due November 13, 2026 at 4:00 p.m. EST. The solicitation is a Request for Proposals, attached as 852351engRadnor.pdf.

The scope spans four disciplines. Civil work includes survey, utility coordination, safety upgrades, stormwater drainage design, erosion and sediment control plans, and construction specifications. Structural work covers feasibility evaluation of replacement alternatives and detailed design of a precast concrete box culvert with a 10-foot clear span. Geotechnical work includes site reconnaissance, subsurface drilling, laboratory testing, and foundation analysis. Environmental services include a Phase I bog turtle habitat survey, wetland presence/absence investigation, archaeological confirmation, and Chapter 105 permit preparation. A comprehensive Hydrologic and Hydraulic Analysis prepared by Gannett Fleming in June 2023 is already complete and determines the proposed culvert will not increase water surface elevation during the 100-year flood event.

Proposals must include firm qualifications, technical approach, and at least three references for similar municipal projects. The fee proposal may be a lump sum or not-to-exceed amount, broken down by task categories including Structural, Civil, Environmental and Stormwater, Geotechnical, Environmental, Permitting, Specifications, and Bid Support, with separate hourly rates for staff. Submissions require one electronic PDF and five bound hard copies delivered to the Radnor Township Engineering Department at 301 Iven Avenue, Wayne, Pennsylvania 19087.

Evaluation factors are relevant municipal experience, understanding of project requirements, technical design approach, completeness of proposal, proposed schedule, proposed fee, and qualifications of key personnel. Proposing firms must provide certificates of insurance for workers' compensation, employer's liability ($1 million), commercial general liability ($2 million general aggregate and $1 million each occurrence), comprehensive automobile liability ($1 million combined single limit), umbrella liability ($2 million), and professional liability ($1 million per claim and $2 million aggregate), with Radnor Township named as additional insured.
