Sourcing advisory from RFP to contract award

Consulting & design · Baseline → Requirements → Fit → Procurement → Delivery support

Procurement is where careful preparation either pays off or comes apart. A scope with room for interpretation gets read differently by every bidder. An equivalence clause with no boundaries invites redesign. By the time bids arrive, you are no longer comparing like with like.

We turn the agreed design basis into a procurement package that protects it: an RFP with controlled scope, clear coordination points, and comparison logic that keeps bids aligned from first submission through to award.

This stage turns what you have agreed into a package suppliers can price and deliver against. It sets scope boundaries, comparison logic, and contract carry-through so the same requirements remain clear from award into delivery. Whether you are building the RFP from scratch or bringing order to bids already on the table, the aim is the same: clearer decisions and a contract that matches what was requested.

OFFER

Write specs that keep bids comparable

We turn the selected treatment line into an RFP-ready scope with coordination points, delivery checks, and comparison logic so procurement supports delivery.

SET constraints that matter most SET coordination points + operating range DEFINE delivery checks + information depth REDUCE brochure-fit outcomes
Where projects drift

Procurement focuses on price and brand while scope and delivery checks stay vague. The result is late changes, disputes, and difficult commissioning.

What we define
  • Scope boundaries and coordination points.
  • Information needed for KPI tests, monitoring, and data handover.
  • Comparable evaluation with weights, risks, and lifecycle cost.
How this changes delivery

Bids become directly comparable. Clarifications reduce surprises, and contract handover requirements are clearer before award.

Scope boundary

We define the process-side procurement basis that keeps supplier offers comparable, including scope intent, measurable obligations, coordination points, and the technical checks that need to hold through clarification, evaluation, and award.

SOURCING VIEW

Most sourcing issues start before the first bid arrives

Vague scopes and unbounded “equivalents” create proposals that cannot be compared. We set the sourcing operating range so bidders can respond without changing the project.

SOURCING FOCUS · OWNER-SIDE SUPPORT

Turn design intent into a controlled sourcing process, not a fresh design contest.

By the time we reach sourcing, a lot of thinking has already been done: treatment objectives, reuse routes, sludge strategy, savings targets, and the way the plant should be operated day-to-day. Our role is to protect that intent when the project hits the market.

We work with you to make sure the RFP doesn’t just list equipment - it captures how the system must behave across flows, loads, seasons and operating scenarios. Vendors then compete on how well they can deliver within those ranges, rather than on who can creatively dilute the scope.

For each sourcing exercise, we clarify:

  • Which elements are non-negotiable (capacity, space limits, outlet quality, reuse commitments).
  • Where flexibility is welcome (process route variations, skids vs. stick-built, phasing options).
  • How total cost of ownership will be compared, not just headline CAPEX.
  • What information will be required at bid stage versus post-award review.

This gives your internal stakeholders, lenders and audit teams a clear line of sight from project objectives through to the chosen delivery partner and contract form.

Pathway 1 · RFP & scope definition

Drafting or reviewing RFPs so that requirements, reuse targets, coordination points and information needs are explicit. We align the technical schedule, commercial schedule and appendices so vendors see one connected basis instead of conflicting signals.

Pathway 2 · Evaluation & TCO approach

Building the evaluation matrix, scoring logic and TCO comparison basis before bids arrive. This includes how to treat energy, chemicals, sludge handling, maintenance access, warranties and upgrade paths - so “cheapest” does not quietly become “most expensive to live with”.

Pathway 3 · Clarifications & deviations control

Structuring clarification rounds, bidder Q&A and deviation logs so that scope shifts are visible and traceable. We help you respond consistently, distinguish genuine innovation from scope erosion, and capture any agreed changes back into the evaluation record.

Pathway 4 · Negotiation, award & handover to delivery

Supporting commercial and technical negotiations through to a recommended award. We help embed performance ranges, review plans and coordination responsibilities into contract schedules so the implementation team does not have to “rediscover” them later.

When this support is useful

Use this pathway when you are close to going to market, or when bids have already landed and it is difficult to see where they are truly comparable. We help when scopes are fuzzy, “equivalent” options look very different on paper, or when internal teams need a clear structure before taking commercial positions.

The goal is to stabilise the sourcing basis: what is in and out of scope, which performance ranges matter, and how risk is being priced. Once those anchors are set, negotiation becomes about value and delivery - not about fixing basic gaps in the RFP.

Typical situations

  • New plants, expansions or major retrofits at a single site.
  • Delivery-partner engagement of critical blocks (reuse lines, sludge systems, odour control).
  • Multiple offers with different levels of detail and assumptions.

What you may already have

  • A preferred process direction and performance targets.
  • Budget ranges and internal deadlines.
  • Stakeholder or lender questions you must be able to answer.

What you still need

  • A market-ready scope with controlled equivalence.
  • A visible scoring / comparison basis (technical + commercial).
  • A decision trail that holds up to audit and review.
Stage A

RFP development & sourcing operating range

Here we translate the design logic into a sourcing-ready view. We separate what bidders must supply from what stays with the owner or other parties, define the operating range in which offers will be judged, and set the rules for where genuine innovation is allowed without compromising performance.

The outcome is an RFP pack that is specific enough to protect the plant, but flexible enough that good ideas can still emerge. It gives bidders the confidence to price clearly, and gives the owner a stable basis for evaluation and negotiation.

STAGE A · DEFINE
Scope definition (what is being bought)

Set the boundaries so bids stay comparable.

  • Scope statement: full plant vs packages vs specific process blocks.
  • Coordination points: utilities, civil, E&I, controls, buildings and access.
  • Operating range + inlet assumptions (what the system must tolerate).
  • Performance KPIs and guaranteed conditions (quality, flow, uptime).
  • Tender return requirements (drawings, datasheets, OPEX inputs).
STAGE A · DEFINE
Scope definition (what is being bought)

Set the boundaries so bids stay comparable.

  • Scope statement: full plant vs packages vs specific process blocks.
  • Coordination points: utilities, civil, E&I, controls, buildings and access.
  • Operating range + inlet assumptions (what the system must tolerate).
  • Performance KPIs and guaranteed conditions (quality, flow, uptime).
  • Tender return requirements (drawings, datasheets, OPEX inputs).
STAGE A · CONTROL
Allowable innovation criteria (controlled equivalence)

Allow innovation without losing control of outcomes.

  • Mandatory requirements vs ‘equivalent acceptable’ requirements.
  • Deviation schedule format (what changed, why, risk, support).
  • Rules for substitutions (where they’re allowed / not allowed).
  • Information required for alternatives (case studies, test data, refs).
  • How equivalence is scored/accepted and who approves it.
STAGE A · SCORE
Techno-commercial evaluation criteria

A scoring system that prevents ‘nice brochures’ winning.

  • Weighted scoring matrix (technical, commercial, delivery, support).
  • Pass/fail checkpoints and minimum thresholds (disqualifiers).
  • Information requirements for each criterion (not just claims).
  • Risk & non-compliance penalties (transparent adjustment logic).
  • Clarification rules so all bidders are treated consistently.
STAGE A · COST
TCO / life-cycle & risk visibility

Compare CAPEX with the OPEX you’ll actually pay.

  • TCO workbook template (energy, chemicals, consumables, sludge, maintenance).
  • Assumptions sheet (tariffs, operating hours, disposal routes).
  • Spares/consumables schedule and maintenance frequency expectations.
  • Risk register: performance, delivery, warranty, operability impacts.
  • Normalisation rules so each bid is evaluated on the same basis.
STAGE A · PACK
RFP pack elements we can help assemble

A bidder-ready pack with clear annexes.

  • RFP table of contents and scope annex (what bidders must include).
  • Process / equipment specs and datasheet formats.
  • P&IDs, layouts and utilities schedule expectations.
  • Instrumentation & controls annex (I/O, alarms, reporting).
  • QA / ITP and commissioning / completion requirements.

Typical sourcing patterns we support

Every tender has its own constraints, but some scenarios repeat. We use these patterns as working templates to stabilise scope, operating ranges and evaluation logic - then adapt them to your specific plants, networks and commercial context.

NEW PLANTS · GREENFIELD

Full-plant tenders for new STPs / ETPs

Align design intent, reuse ambitions and discharge limits with bidder scope, so civil, process and automation are priced against one connected basis instead of separate “lot-wise” assumptions.

RETROFITS · UPGRADE PERIODS

Capacity upgrades and compliance-driven retrofits

For plants that must stay online while capacity, reuse or nutrient performance is improved. We set out phasing, bypasses and interim operating ranges so bidders compete on workable upgrade paths, not just on paper guarantees.

MULTI-SITE · FRAMEWORKS

Multi-site or approach sourcing

For utilities or groups rolling out similar solutions across several sites. We align common requirements and site-specific ranges so pricing, risk and performance stay comparable without forcing one-size-fits-all designs.

INSIGHT

Value engineering is only useful when the project is still bounded

We want vendors competing on better delivery and better performance inside a known operating range - not redefining the project through scope creep.

Stage B

Bid evaluation, clarifications & award readiness

Once bids arrive, we test them against the agreed operating ranges and evaluation criteria, then normalise the offers so you have a like-for-like view of both technical risk and commercial exposure. Clarifications are managed in a structured way, so every change is traceable back to the original RFP intent.

This stage is where hidden assumptions and “grey zones” become visible. We help you see how risk is being priced, where offers can be aligned without distorting competition, and what still needs to be resolved before award and kick-off.

  • Prioritised negotiation agenda (must-have vs tradeable).
  • Redlines for commercial terms and warranty protections.
  • Performance guarantee tightening and information requirements.
  • Connection responsibilities set out clearly (who does what).
  • Fallback options and ‘walk-away’ triggers defined.
STAGE B · AWARD

  • Kick-off checklist (connections, submittals, timelines).
  • Initial implementation roadmap aligned to the delivery review plan.
  • Handover of logs/templates to the delivery team.

Typical outputs

The outputs from this pathway are compact but heavy-duty. They keep the project controlled and make decisions easier to compare and record for internal sponsors, external lenders and future audits.

Each artifact can be reused across tenders, so sourcing maturity builds over time instead of being buried in a one-off spreadsheet.
