Compare proposals against one shared, non-sensitive brief; normalize scope, exclusions, responsibilities, evidence, schedule assumptions, documentation, warranty terms, and price before treating totals as comparable.
Use one non-sensitive brief
Give each prospective firm the same high-level project stage, objectives to be evaluated, budget band, timeline, decision process, and professional-team context. Do not include addresses, drawings, access details, protected identities, response procedures, or known vulnerabilities in an initial comparison request.
Normalize scope and responsibility
Set proposal totals beside a written list of inclusions, exclusions, allowances, dependencies, and responsible parties. Ask each proposer to identify who owns coordination of interfaces, construction conditions, documentation, installation, and handoff; do not infer complete-project responsibility from a component or service label.
Keep evidence and commercial terms separate
Ask each firm to identify the source, stated scope, and limitations for any evidence it offers, then review schedule assumptions, documentation, warranty terms, change process, and price as separate proposal questions. A lower total may reflect a different scope, not an equivalent project.
Choose an appropriate next conversation
Before disclosing more, confirm who will receive information, why it is needed, how it will be retained, and whether a less sensitive alternative is sufficient. Project-specific advice, qualifications, contracts, and applicable requirements should be assessed by the relevant qualified professionals.
