Maceira Zayas represents contractors, subcontractors, and government agencies in public procurement matters in Puerto Rico and before federal agencies, with offices in San Juan and Washington, D.C.

The firm advises at every stage of the contracting cycle: pre-award strategy and bid preparation, proposal review, contract negotiation, performance and modification, claims and disputes, and closeout. It handles bid protests, compliance reviews, organizational conflicts of interest, and suspension and debarment proceedings.

The practice draws on direct experience inside government. Attorneys at the firm drafted procurement regulations, evaluated competitive bids, and administered contract awards for Puerto Rico agencies. That background shapes how the firm counsels private clients: it knows how procurement decisions are made, and it knows where they go wrong.

Puerto Rico contracts. The work runs under Act 73-2019, the statute that centralized Commonwealth procurement in the General Services Administration (ASG), as amended by Act 153-2024, which rewrote the deadlines that govern challenges. The firm represents clients before the ASG Bid Review Board (Junta Revisora de Subastas), the Court of Appeals, and the Supreme Court of Puerto Rico, and advises on RUL and RUP registry eligibility questions.

Federal contracts. The firm advises on the Federal Acquisition Regulation (FAR), DFARS, Buy American and Build America, Buy America requirements, small business and set-aside programs, and the compliance rules that follow federal funds into Puerto Rico under 2 CFR Part 200, including FEMA public assistance and HUD CDBG-DR programs.

The firm has prevailed in bid protests before the Puerto Rico Court of Appeals and defended contract awards at every administrative and appellate level, including the ASG Bid Review Board and the Supreme Court of Puerto Rico. Combined value of matters handled exceeds $400 million.
