RFSQ On-Call General Engineering Services

The City of Tolleson, Arizona, is requesting Statements of Qualifications from professional engineering firms to establish an on-call general engineering services contractor list, with submissions due August 19, 2026, at 3:00 p.m. Phoenix time. The City will award multiple contracts to qualified firms capable of delivering architectural services, transportation engineering, surveying, traffic engineering, general civil, plan review and inspections, and geotechnical services across municipal infrastructure and development projects.

The scope encompasses engineering evaluations, design plans, specifications, construction administration, inspection services, permit-ready construction documents, and project management. Services will be delivered on individual task orders or authorizations.

Pricing is capped at $500,000 per individual purchase order or authorization, with no single consultant awarded more than $2 million in aggregate value per contract year. Selected firms will receive Professional Services On-Call Agreements with an initial one-year term, renewable at the City's discretion for up to four consecutive one-year periods. The City conducts annual performance reviews to determine renewal eligibility and will evaluate performance within 45 days of project completion. No minimum volume of work is guaranteed.

Evaluation weighs consultant team composition (20 points), firm capabilities and relevant technical experience (30 points), past performance and references from the past three years (35 points), and scheduling, project management, and communication plans (15 points). The City reserves the right to conduct interviews with the highest-scoring respondents, though no interviews are currently planned. No binding contract exists until City Council approves and executes a written agreement. The City retains the right to reject any or all submissions, waive informalities, and terminate agreements at its sole discretion. All submittal costs are the responsibility of the respondent.
