02The honest problem

Curtain walling bids are won on structural and testing evidence.

Curtain walling sits at the high-value, high-liability end of the façade market. CWCT testing, EN 13830 compliance, fire-cavity barriers, wind-load and structural design responsibility — the tender evaluation is structural-engineering-grade, not finishes-grade.

The main contractor's design team scores this submission. They want to see structural calc framing, weather-tightness testing evidence, installation tolerance methodology, and a scaffold-and-access strategy that fits the building's grid.

Most façade firms can build it. Few of them write the bid pack to the level of structural rigour the tender demands.

03What’s hard about it

The three problems that cost you the appointment.

  1. 01

    Structural design responsibility framing

    Curtain walling design typically splits between consultant's performance spec and the façade contractor's detailed design. The bid pack must state explicitly which calculations and which compliance evidence the façade contractor is producing — and against what loadings.

  2. 02

    CWCT testing & EN 13830 compliance

    Tenders ask for CWCT testing evidence against the actual configuration. Generic CWCT certificates without configuration mapping lose points. The pack needs to frame which CWCT clauses are tested, by whom, and against which mock-up.

  3. 03

    Scaffold & access strategy

    Curtain walling installation depends entirely on the scaffold and lifting strategy. The bid pack should propose a coordinated approach with the main contractor's scaffold sub — not leave it as a clarification.

04London market context

Why bid evaluation in London works the way it does.

London is tier-1 territory for almost every commercial trade. Bid evaluation is run by structured procurement teams inside Mace, Skanska, ISG, Multiplex, Lendlease, Sir Robert McAlpine, Galliford Try and the rest. Most opportunities are framework awards, multi-tier subcontracting, or sole-source down a national supply chain. Tight sites, complex logistics, late-night working, congestion-zone constraints and post-Grenfell fire compliance are baked into every tender.

London-active subcontractors fight against bigger national rivals on every bid. Capacity, fit and reputation matter — but the bid pack does most of the qualifying work before the QS ever sees a price. For specialist trades like cladding, curtain walling and fire stopping, the bid pack effectively IS the qualification.

05How it works

    You review and submit

    Your name on it. Your win.

  4. 04

09Frequently asked

Curtain Walling bid writing — practical answers.

01How much does a no-win-no-fee bid writer cost for a London curtain walling tender?
£0 if your bid doesn't win. £1,500 minimum if it does, or 2% of contract value on tenders above £75k. There's no upfront fee, no retainer, no hourly rate. The fee is invoiced once you confirm the contract award. Eligible on opportunities over £50k.
02What's included in a curtain walling proposal pack?
Method statement, structural and weather-tightness design responsibility framing, CWCT testing and compliance evidence, fire-cavity and EN 13830 compliance narrative, installation and witness regime, scaffold and access strategy, programme narrative with grid sequencing, defect rectification approach, and experience matrix mapped to evaluation criteria.
03How do you handle the structural design responsibility split?
Explicitly. The bid pack states whether the façade contractor is producing detailed structural design against the consultant's performance spec, or working to a fully-designed package. CWCT testing, wind-load calc framing and EN 13830 compliance are mapped to that split so the design team can see where liability sits.
04How long does a curtain walling bid pack take to write?
Façade packages are document-heavy. Standard sub-packages take 5–10 working days because the structural and testing evidence requires careful framing. Frameworks for high-rise residential or specialist commercial take 10–15 days. We won't compress that to the point of weakening the structural narrative.
05Are you tied to any specific curtain walling system?
No. We write to whatever system you've priced (Schueco, Reynaers, Kawneer, Sapa, Senior Architectural, Technal, Wicona). The proposal frames your chosen system's CWCT testing, EN 13830 compliance and structural credentials in the main contractor's language.
06Do you understand the London tender market?
Yes. London is one of our active regions. We work with subcontractors bidding into Mace, Skanska, ISG, Multiplex, Lendlease, Galliford Try and the rest of the tier-1 London supply chain. We understand the framework-award process, the multi-tier subcontracting standards, and the post-Grenfell fire-compliance evidence demands that govern London tenders. We also cover the South-East counties and work UK-wide on cold opportunities up to £5m contract value.
