On-Call Engineering Services Water, Wastewater, and Solid Waste Projects

Calvert County Government is requesting technical and price proposals from qualified Maryland-registered engineering firms or individuals to provide on-call water, wastewater, and solid waste engineering services for various projects throughout Calvert County, with proposals due September 8, 2026 at 2:30 p.m. and virtual bid opening at 3:00 p.m. the same day. No pre-proposal meeting is scheduled, and written questions are due August 25, 2026.

Scope encompasses design of civil engineering construction projects, water and wastewater system analysis and design, solid waste facility improvements, environmental monitoring, permitting assistance, rate studies, and construction-phase support services. All work must comply with generally accepted standards of professional engineering practice and applicable Federal, State, and local codes and regulations. The RFP does not specify guaranteed quantity estimates; work is assigned through task orders on an as-needed basis.

Pricing is submitted on a unit-rate basis covering fourteen line items: hourly rates for senior project managers, engineers in multiple disciplines (structural, civil, environmental, and others), surveyors, CADD operators, and support personnel, plus costs for deliverables such as plan sheets and report copies. All prices must include overhead and multipliers. Estimated annual quantities are provided for bid comparison purposes only. Prices are firm for the first year; escalation requests in renewal terms are evaluated against the Consumer Price Index for the Washington Metropolitan Area, capped at three percent maximum if approved.

The initial contract term is one year from Notice to Proceed, with four optional one-year renewal periods under the same terms and conditions, automatically renewing unless either party provides ninety days' notice of nonrenewal. Calvert County reserves the right to make multiple awards across engineering disciplines and may competitively bid certain projects separately. Payment is made monthly upon satisfactory completion and proper documentation. The county retains the right to withhold up to ten percent of design fees through project completion and additional funds in cases of dispute or defective work.
