Detailed Design & Funding Approval
Locking Down Total Commercial and Technical Predictability.
Before a manufacturing business releases significant capital funding, every engineering variable must be accounted for. Stage Three is where we eliminate variables and speculation, transforming your preliminary layouts into a completely costed, legally compliant, and contractually binding execution package.
Don’t let your next engineering project proceed on guesswork.

Stage 3
By driving rigorous structure through the detailed design and tendering process, we build an unshakeable commercial shield around your CapEx. This phase marks the final, critical gateway: you do not progress to installation until the project passes through a strict stage-gate review for full executive funding approval.
1. Advancing to Detailed Design
We move from general arrangements into the exact granular engineering specifications required for manufacturing, installation, and system integration.
Granular Engineering
Finalising precise mechanical piping and instrumentation diagrams (P&IDs), isometric drawings, structural loading calculations, and complex electrical loop diagrams.
Control & Automation Architecture
Mapping out exact PLC configurations, SCADA network topologies, and software functional design specifications (FDS) to ensure new assets integrate seamlessly into your legacy infrastructure.
2. Identifying Procurement Packages
Breaking a massive installation down into distinct, logical procurement packages prevents overlapping vendor costs and simplifies on-site contractor management.
Strategic Categorisation
Dividing the project into manageable packages—such as civil works, mechanical installation, process pipework, automation, and principal equipment supply.
Interface Mapping
Setting strict, unambiguous technical and physical boundary lines between each vendor package to ensure no gaps in responsibility occur during installation.
3. Engaging the Vendor Network
Leveraging our extensive network of tier-one industrial suppliers and contractors, we issue the technical packages to vendors who match your exact site culture and engineering standards.
Pre-Qualification Checks
Vetting suppliers for technical capability, financial stability, and health and safety competence under CDM 2015 standards.
Technical Alignment
Conducting detailed pre-tender briefings to ensure vendors fully grasp your operational constraints and User Requirement Specifications (URS).
4. Driving the Tendering Process
We manage a competitive, transparent, and rigorous tendering process to ensure your business achieves genuine commercial value without sacrificing engineering quality.
Apples-to-Apples Comparison
Normalising all vendor bids to ensure they are being evaluated on identical technical criteria, materials, and delivery timelines.
Commercial De-risking
Stripping out hidden vendor exclusions, assumptions, or open-ended variation clauses that could threaten your budget later.
5. Precise Budget Generation
We replace high-level estimates with a definitive, itemised project budget built on fixed-price contractor quotes and guaranteed equipment lead times.
Total Transparency
Creating a comprehensive cost breakdown that factors in contingency, delivery, on-site commissioning costs, and necessary factory shutdown resources.
Predictable Cash Flow
Mapping out a realistic capital expenditure schedule aligned with project milestones.
6. The Full Business Case with Quantified Benefits
We tie the fixed project costs back to your original business drivers, creating an unshakeable, executive-grade document that justifies the investment to the board.
Guaranteed Return on Investment
Defining exact payback periods backed by fixed tender costs and verified operational performance increases (such as reduced energy usage or improved OEE).
Risk-Adjusted Models
Presenting a clear analysis of the financial protection this structure provides against operational disruption or compliance failures.
7. Securing Implementation Funding
With the full business case finalised, we help you secure internal capital allocation by presenting a project that is entirely de-risked and ready to execute.
Executive Readiness
Providing the clear, data-driven narrative that Financial Directors and Managing Directors need to release capital funds with total peace of mind.
Gateway Governance
Packaging all engineering data, compliance strategies, and fixed commercial bids into a comprehensive capital application.
8. Agreeing Key Performance Indicators (KPIs)
Before any contracts are signed, we establish exactly how the project's success will be measured, monitored, and contractually enforced.
Project Delivery KPIs
Setting strict milestones for timeline adherence, health and safety metrics, and budgetary control.
Operational Performance KPIs
Agreeing on clear mechanical performance targets—such as cycle times, scrap rates, and commissioning handover criteria—that vendors must legally achieve.
9. Design Qualification (DQ)
As part of our fundamental engineering standard, we execute a formal Design Qualification process to verify that the proposed detailed design meets every requirement of your URS.
Traceability Matrix
Mapping every technical detail of the final design directly back to your operational, quality, and regulatory needs.
Compliance Sign-Off
Providing documented evidence that the design adheres to all relevant British Standards, hygienic guidelines, and safety legislations before manufacturing begins.
🛑 The Stage Gate: Funding Approval
Every piece of work executed in Stages 1, 2, and 3 culminates right here. The project must pass through our formal Funding Approval Stage Gate before a single penny of implementation capital is spent.
We review the finalised design, the fixed tender values, the CDM health and safety file, and the quantified benefits with your executive team. Only when the board has absolute clarity, total confidence, and has formally approved the funding do we unlock Stage 4: Execution.
Your Reputation, Protected
Stage Three is where a project stops being a proposal and becomes a commitment. Every figure is fixed, every variable is accounted for, and every risk has been engineered out before the board is asked to release a penny.
When the board signs off at Stage Three, they are not signing off on a hope. They are signing off on a fixed-cost, fully de-risked execution package with legally binding KPIs. That is the standard we hold every project to.
Our Guarantee
At Legacy Manufacturing Solutions, we stand behind the quality, accuracy, and reliability of every project we deliver.
We guarantee that all work completed by our team will meet the agreed outcomes as defined during the project specification phase and formally approved by the client. If, for any reason, we do not meet the outcomes we have committed to, we will deliver the outstanding elements at our own cost.
This guarantee reflects our commitment to accountability, transparency, and consistently delivering value for our clients.
Your success is our priority — and we ensure it by backing every project with this promise.
