Start with the project decision, not a generic environmental package
Environmental work is valuable only when it answers a decision your project must make. An acquisition may need a property-condition assessment and liability protection. A redevelopment may need investigation of historical releases, a remediation plan or regulator coordination. A construction program may need permits, pre-construction controls, monitoring and compliance support. Those are different scopes, even when the same site is involved.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Write a one-page project brief
Give every prospective firm the same facts:
- Street address, parcel boundaries, municipality, state or province and country.
- Current and proposed land use, including residential, commercial, industrial, institutional or infrastructure use.
- Construction type, approximate area, depth of excavation, dewatering, demolition, utility work and other planned disturbance.
- Known current and historical uses, neighboring uses, storage tanks, spills, fill, waste handling or prior environmental reports.
- Project milestones, bid date, closing date, mobilization, major excavation and required decision dates.
- Funding or lender conditions, including whether a Phase I environmental site assessment (ESA) must satisfy the federal All Appropriate Inquiries (AAI) rule.
- Reports and data already available, contacts for interviews and the people authorized to approve additional work.
State the decisions the consultant must support: proceed, redesign, investigate further, negotiate an indemnity, obtain a permit, prepare a construction environmental plan or stop work when a discovery occurs. A clear decision statement prevents firms from pricing different interpretations of “environmental assessment.”

Use one request for proposals
Ask each firm to respond to the same task list and to identify every assumption, exclusion, owner input, optional service and deliverable. Request separate prices for required and optional tasks. This makes a low bid visible when it omits interviews, field reconnaissance, regulatory coordination, quality review or construction-phase support.
Confirm the applicable standard and professional qualification
For a Phase I ESA intended to support AAI, ask the firm to identify the standard it will use and why it fits the property. The U.S. Environmental Protection Agency identifies ASTM E1527-21 and ASTM E2247-23 as practices consistent with the AAI rule. E2247-23 is intended for forestland or rural property; E1527-21 is generally used for other property types. The proposal should state the edition, explain any deviation and identify the environmental professional responsible for the work and report.
AAI is a process for evaluating environmental conditions and potential liability; it is not a guarantee that a property is free of contamination. If EPA Brownfields Assessment Grant funds are paying for the Phase I, EPA states that the assessment must comply with the AAI Final Rule at 40 CFR Part 312. Confirm whether that funding condition applies to your project.

Do not look for an EPA-issued certification
EPA’s Brownfields FAQ states: “EPA does not certify environmental professionals nor does EPA advise on how to meet the qualifications for an environmental professional.” The professional self-certifies that he or she meets the AAI qualifications in the report. Ask for the person’s education, professional experience, relevant site work and the signed report language, rather than accepting a claim that EPA certified the individual.
Ask about standards outside AAI
If the assignment includes permitting, construction monitoring, remediation design, industrial hygiene, ecological work or engineering, list the discipline and governing requirement separately. A Phase I standard does not define every service a construction project may need. Require the firm to identify which parts it performs itself and which require a qualified subconsultant.
Compare the people who will actually do the work
A firm’s brochure describes its capacity; the named team determines your experience. Require names, roles, location, availability and a short description of comparable projects for each key person.

- One-Handed Loading - Keep one hand free with a 1/4 in. hex chuck that accepts 1 in. bit tips
Field staff and technical lead
- Who will conduct the site reconnaissance, interviews, records review and sampling, if sampling is included?
- Who will oversee the work and sign the report?
- How many comparable construction sites has each person handled, and what made them comparable?
- What is each person’s availability during your required field window and review period?
- Who will replace a team member if that person leaves or becomes unavailable?
Ask for a responsibility matrix showing the project manager, field lead, technical reviewer, permitting lead and commercial contact. A proposal that names only a senior principal but cannot identify the working team creates delivery risk.
Independent quality review
Find out whether a second qualified professional reviews the report before issue, what that review covers and whether corrections are tracked. Ask whether the reviewer is independent of the field team and how urgent findings are escalated before the final report.
Examine the method and the report, not just the promise
Compare how each firm will obtain evidence and turn it into a decision. EPA’s suggested report content provides a useful checklist: scope, methodology, assumptions, limitations, deviations and user-supplied information should be explicit.
Evidence-gathering plan
Require the proposal to describe records and databases to be reviewed, historical sources, interviews, site reconnaissance, photographs, mapping and any sampling or laboratory work. Ask which sources are unavailable, how gaps will be handled and what facts would trigger additional investigation.
Findings and limitations
A usable report distinguishes observed conditions, historical records, interview statements and professional judgment. It should state the search dates or coverage, unresolved data gaps, reliance on information supplied by the client, limitations on access and any deviation from the selected standard. Do not accept a conclusion that hides a limitation in a footnote.

Assess construction permitting and compliance capability
Environmental requirements vary with location, project facts and construction activity. A firm should not promise a universal permit list without first reviewing those facts. Ask it to identify the expected role for permitting and compliance planning, the authorities it has worked with in the project jurisdiction and the construction activities that could create obligations.
Questions for the proposal
- Which permits, notifications, plans or monitoring programs do you believe may be relevant, and what assumptions support that view?
- Will you prepare applications, provide technical exhibits, attend regulator meetings or only advise the owner?
- Who will inspect or monitor work, how will observations be documented and how quickly will a noncompliance issue reach the project manager?
- How will permit conditions be translated into subcontractor requirements, inspection checklists and stop-work or discovery procedures?
- What services are excluded, such as cultural resources, ecological surveys, geotechnical work, surveying or legal advice?
EPA’s construction guidance emphasizes accounting for environmental requirements before bidding. Include the consultant early enough for permit conditions and environmental controls to affect the drawings, bid documents, schedule and site logistics rather than treating compliance as a field-only task.
Plan for discoveries and follow-up investigation
Ask each firm what happens when the Phase I identifies a recognized environmental condition, a data gap or another concern. The answer should cover escalation, decision authority, scope, schedule, laboratory or specialist involvement and price authorization.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsPhase II is a decision, not an automatic add-on
EPA notes that a Phase II ESA may be needed after a Phase I to better understand contamination type and extent. That does not mean every Phase I finding requires Phase II work. A credible proposal explains the facts that would justify sampling, the objectives of that sampling and the alternatives if the client decides not to proceed.
Require a controlled change process
Specify who may authorize additional work, the information required in a change proposal, unit rates or fixed prices, laboratory markups, schedule effects and the format of interim results. Require written approval before non-emergency work begins. Define an emergency path for conditions that threaten people, the environment or active construction, followed by prompt documentation and commercial reconciliation.
Use a weighted evaluation matrix
Score every proposal against the same evidence. The weights below are an illustrative starting point; change them to reflect your project’s risk, urgency and funding requirements. Set mandatory pass conditions first so a low score in a non-negotiable area cannot be offset by a low fee.

Compare fees without creating false savings
No reliable market-wide price or turnaround benchmark is established for this work. Obtain comparable bids by keeping the scope constant and asking firms to separate:
- Fixed fees for required tasks and deliverables.
- Unit rates for sampling, laboratory analysis, travel, meetings, inspections and additional reporting.
- Optional services with a clear trigger for using them.
- Subconsultant costs, pass-through expenses and applicable taxes.
- Rates for additional personnel, rush work, regulator meetings and construction-phase support.
Check whether the fee assumes unrestricted site access, complete records, cooperative interviewees, no weather delay, one review cycle or no regulator comments. Compare the cost of those assumptions, not just the base total. Ask how invoices tie to milestones and whether unused optional allowances are removed from the final bill.
Insurance and liability terms
Request current evidence of professional liability or errors-and-omissions insurance, general liability and any coverage your contract requires. Review limits, deductibles, exclusions, claims-made dates and who bears the risk of subcontractors. Older EPA selection guidance identifies quality assurance, risk management, standard contract terms and E&O insurance as useful selection topics; treat that guidance as a prompt and verify current policies and wording directly.

- Define the brief. Record site facts, decisions, standards, funding conditions, milestones and required permits or compliance outcomes.
- Prequalify for capability. Remove firms that cannot show the required disciplines, jurisdictional experience, insurance or availability.
- Issue the identical RFP. Include background data, scope, proposal format, questions deadline, site-visit rules, pricing format and evaluation criteria.
- Hold a controlled clarification period. Answer bidder questions in writing and send the same addenda to every bidder.
- Score written proposals. Apply the matrix before discussing price so omissions are not overlooked.
- Interview the proposed team. Ask the field lead and technical reviewer to explain a comparable project, a difficult finding and an example of a report correction.
- Check references. Ask the client whether the named team delivered on schedule, controlled changes, communicated bad news and produced a report the client could use.
- Clarify the shortlist. Issue a written list of scope gaps, assumptions, schedule conflicts and commercial exceptions and request final responses.
- Negotiate and document the award. Attach the final scope, deliverables, schedule, fee sheet, rate card, reliance terms, insurance requirements, change process and escalation contacts to the contract.
- Kick off before fieldwork. Confirm access, health and safety rules, interview contacts, document transfer, reporting format, emergency contacts and the authority to approve additional work.
Red flags that should change your decision
- The firm promises an “EPA-certified” environmental professional or cannot explain the professional’s AAI qualifications.
- The proposal uses a generic Phase I scope without identifying the property type, standard edition, deviations or intended user.
- Required tasks are hidden in assumptions, exclusions or optional services.
- The named senior expert is unavailable, while the working team is unnamed or inexperienced on comparable sites.
- The report sample omits limitations, source coverage, maps, photographs or a clear link between findings and recommendations.
- The firm cannot describe who will coordinate with local authorities or how permit conditions will reach the contractor.
- Additional work is priced only as “time and materials” with no authorization threshold, rate sheet or schedule impact.
- The lowest price depends on one site visit, no quality review, no regulator interaction or an unrealistic report date.
Make the contract support construction decisions
Attach a responsibility matrix identifying what the owner, designer, contractor and consultant each provide and approve. Define report recipients and reliance rights, document retention, confidentiality, data ownership, subcontractor controls, insurance certificates, notice periods and the process for correcting errors. State how urgent environmental conditions are communicated during active work and who can direct a pause while facts are confirmed.
At the kickoff, convert the proposal into a milestone schedule tied to design release, bidding, closing, mobilization, excavation and permit obligations. Require an early notice when information is missing or a finding could affect cost or sequence. This is more useful than discovering at final report review that the consultant interpreted the decision differently from the project team.

Questions to ask before you sign
- What exact decision will each task support?
- Which standard and edition apply, and what deviations are proposed?
- Who qualifies as the environmental professional, who signs, and who performs the fieldwork?
- What information is assumed, what is excluded and what will trigger a change?
- What will the client receive, in what format, and when?
- How will a potential release, unexpected material or permit issue be escalated during construction?
- What local authorities and project types has the team worked with?
- What is included in the fee, what is optional and how are additional services authorized?
- What insurance and liability terms apply to the firm and its subcontractors?
- Which references can confirm the performance of this specific team?
Because no project location, site history, construction type or intended use was provided here, the required scope and permits cannot be determined in the abstract. Verify current state, tribal and local requirements with the relevant authorities and your project’s legal, design and engineering advisers. Select the firm whose documented method, people and contract commitments fit those verified requirements—not the firm that simply presents the shortest proposal or lowest initial number.
Frequently Asked Questions
Does a Phase I ESA automatically require a Phase II investigation?
No. A Phase II may be appropriate when Phase I findings or data gaps require sampling to understand contamination type or extent. The consultant should explain the trigger, objective, scope and price before work is authorized.
How can I verify an environmental professional for AAI work?
EPA does not issue a certification. Ask for the professional’s qualifications, experience and signed report language showing that the person meets the AAI requirements, and confirm the selected ASTM standard and any deviations.
What if bidders propose different permits?
Give all bidders the same location, design and construction facts, require each to state assumptions, and have the preferred firm confirm the permit analysis with the relevant authority before finalizing scope.
What should I do when a consultant finds an unexpected condition during construction?
Use the contract’s escalation and change-control procedure: notify the named project contacts, protect people and the environment, document the condition, obtain a written scope and price for additional work, and record the decision to proceed, redesign or investigate.
