Pre-FEED & Feasibility Engineering

De-risk capital expenditure with high-precision Pre-FEED & feasibility engineering.

Acufore Engineering runs Pre-FEED and feasibility studies across 20+ engineering disciplines, applying global engineering standards (ASME, API, Eurocode) to de-risk capital projects before design begins. As brownfield specialists, we scope revamps against the real, as-built plant, not outdated drawings, and return a fixed-fee proposal fast, backed by a dedicated project manager and independent technology selection, free of vendor bias.

The Pre-FEED imperative

Why early concept validation matters

Acufore assesses early process feasibility, tests physical plot boundaries, and models preliminary CAPEX to ensure your concept is executable. We lock down process capacity, plot footprints, and equipment counts early. We provide Basis of Design (BOD) and a bounded FEED Scope of Work.

01

Unvetted concept

Raw process idea, no validated basis

02

Acufore Pre-FEED Scoping

AACE Class 5/4 cost modeling & 3D scan integration

03

Defensible Basis of Design (BOD)

De-risked TIC accuracy within +/- 20%

04

Audit-Ready FEED Handover

Bounded scope for EPCs, minimised CAPEX surprises

Three recurring failure points we eliminate

Inaccurate CAPEX projections

Proceeding without AACE Class 5/4 cost modelling leads to severe budget inflation down the line.

Technology & sizing traps

Choosing the wrong process loop or equipment sizing early causes expensive retrofits during detailed engineering.

Spatial & environmental dead-ends

Ignoring site constraints, access routes, or regional load codes (wind, snow, seismic) delays regulatory approval.

Deliverable Packages

The Pre-FEED execution register

Every Pre-FEED engagement produces a defined, auditable deliverable set.

Deliverable Package Technical Scope Included Business & Project Benefit
Basis of Design (BOD) Process basis, design conditions, codes/standards, and technical assumptions. Single reference document your EPC and capital committee can work from.
Process & Layout Package BFDs, preliminary PFDs, Heat & Mass Balances, utility summary, and initial battery limits. Removes scope ambiguity before FEED contracting begins.
Equipment & Long-Lead Lists API/ASME vessel sizing, long-lead specifications, and preliminary datasheets. Enables early vendor engagement and realistic long-lead procurement timing.
3D Spatial & Plot Plans Conceptual plot plans, skid envelopes, and integrated brownfield 3D point cloud scans. Locks in space allocation early, avoiding costly plot plan revisions in FEED.
Cost & Economics (AACE) AACE Class 5 / Class 4 CAPEX & OPEX estimates, risk register, preliminary schedule, and FEED SoW. Gives your FEED contractor a fixed, fundable scope to price against.

PROCESS ENGINEERING & SYSTEM FEASIBILITY

Capacity, mass balance & technology selection

+
  • Block Flow Diagrams (BFDs) & preliminary Process Flow Diagrams (PFDs).
  • Heat and Mass Balance (HMB) calculations establishing the technical envelope.
  • Process simulation, capacity testing, technology selection matrix, and early equipment datasheets.
  • Key calculations: Heat & Mass Balance, pressure drop, utility consumption sizing.
  • Spatial feasibility, soil bearing capacity reviews, and structural framing concepts.
  • Pedestal loading estimates, modular skid base frame feasibility, and pipe rack spans.
  • Access platforms, walkways, and stairways scoped to OSHA / BS EN 1090 (EXC2) standards.
  • Key calculations: Preliminary structural loading and foundation loading estimates.
  • Conceptual plot plans and preliminary P&IDs defining battery limits.
  • Process skid space allocation, Material Selection Diagrams (MSD), and main pipe corridor routing.
  • Early sizing for long-lead equipment (reactors, ASME/API vessels, heavy pumps).
  • Key calculations: Pump sizing, line sizing, vessel sizing, heat exchanger sizing.
  • Preliminary Single Line Diagrams (SLD) and high-level electrical load lists.
  • Grid tie-in feasibility, main substation requirements, and control system topology.
  • Initial instrument index for your E&I contractor at FEED kickoff.
  • Key calculations: Preliminary electrical load calculations.
Brownfield Revamps

Brownfield digitization & scan-to-3D integration

Brownfield revamps carry a risk greenfield projects don't: the as-built plant rarely matches the historical drawings on file. Acufore integrates point cloud laser scan data and intelligent P&ID digitization directly into the Pre-FEED phase, converting the real, current-state facility into a high-precision 3D model before laying out new equipment.

This allows automated clash detection checks to run while changes are still cheap, preventing costly field collisions between new skids, pipe racks, or structural steel and existing plant infrastructure.

Why teams work with us

We scope capital projects for demanding EPCs and owner-operators

Confidential by Default

A confidential NDA is executed before any process data or file is reviewed.

Multi-Discipline Validation

Process, piping, civil, and E&I disciplines validate every concept in parallel.

Fixed-Fee Proposals

A scoped, fixed-fee proposal comes back after the scoping call, no open-ended billing.

FEED-Ready Handover

Deliverables are built to hand straight into a FEED Scope of Work, no rework at handoff.

FAQ

A Class 5 estimate is the earliest, roughest cost view, produced from a bare concept with wide accuracy ranges (typically +/- 30% to 50%). A Class 4 estimate follows once basic technology selection, primary equipment sizing, and preliminary plot plans are in place, narrowing the accuracy range (typically +/- 15% to 20%) to give a firmer basis for capital sanctioning.
Pre-FEED validates that a concept is technically and commercially viable, producing Class 5/4 estimates, technology selection, and a feasibility-level plot plan. FEED takes a validated concept and builds it out to a design basis solid enough to sanction detailed engineering, with a Class 3 estimate and a full PFD/P&ID set.
Yes. A confidential NDA is executed before any process requirements, concept notes, or RFQ specifications are reviewed.
You receive a documented package explaining why, covering the technology, cost, or spatial constraint that failed, so the decision to stop, redesign, or relocate is backed by engineering evidence rather than guesswork.
Yes. Regulatory compliance roadmaps are built to the region relevant to your project, whether that means ASME/API, IEC/Eurocode/UKCA (Great Britain), or the applicable local equivalent.
