The verdict in three sentences
A project-references corporate site for an engineering consultancy in Singapore runs between 12,000 and 20,000 USD in 2026 for 10-15 pages, plus 5,000 to 9,000 USD if you want a CMS with a validation workflow. The heaviest brick is not the design but the document hub (downloadable technical sheets, references sorted by sector) and the trilingual SEO. Issue the tender with a precise brief, a 40% deposit and a realistic 6-to-9-week timeline.
The detailed quote (2026, USD)
For a consultancy the site exists to win the trust of public and private clients: it must document references, prove certifications and rank on technical queries. Here is the typical breakdown.
| Item | Scope | Price USD |
|---|---|---|
| 10-15 page corporate | Structure, project references, team, disciplines, contact | 12,000 - 20,000 |
| Headless CMS + validation workflow | Multi-level publishing, editorial roles | +5,000 - 9,000 |
| Document hub | Downloadable technical sheets, sector filters | +2,500 - 5,000 |
| Trilingual SEO | Hreflang, meta, internal links, sitemap | +2,000 - 4,000 |
| EU hosting (OVH/Scaleway) | Data compliance, CDN, backups | 90 - 200 USD/month |
| Maintenance | App upkeep + enhancements | 300 - 800 USD/month |
Typical terms: 40% upfront, 30% at design acceptance, 30% on delivery. Keep a 10% envelope for post-launch enhancements.
What moves the price in a tender
Two comparable consultancies can get very different quotes. The decisive 2026 variables:
| Variable | Budget impact | USD range |
|---|---|---|
| Languages (2 vs 3) | + translation and hreflang load | +1,600 - 4,000 |
| Headless CMS vs static site | + editorial governance | +5,000 - 9,000 |
| Volume of references to migrate | + integration and structuring | +1,200 - 4,500 |
| Animation level | + front-end time and QA | +2,000 - 5,500 |
| EU vs local hosting | + compliance and CDN | +600 - 1,800/yr |
A brief that pins these points down prevents non-comparable quotes and change orders.
Mini case study
Sarah, COO of a 22-person engineering consultancy in Singapore, runs a tender. She selects the 10-15 page corporate + headless CMS + document hub: 16,000 + 7,000 + 3,500 = 26,500 USD, plus maintenance 500 USD/month and EU hosting 150 USD/month. Year-1 cost: 26,500 + (12 x 650) = 34,300 USD. Previously her team spent about 6 h/week emailing references to prospects manually. The automated hub removes ~260 h/year; valued at 75 USD/h that is 19,500 USD in annual savings, before counting tenders won thanks to a credible showcase.

FAQ
Why does a CMS with a workflow cost so much?
Because you must configure roles (author, approver, publisher), an approval circuit and previews. Budget +5,000 to 9,000 USD, but it removes agency dependency for every update.
Is trilingual SEO really worth it?
Yes if you target export or institutional markets: hreflang tagging and language-specific content can double the query surface you capture.
Do I need EU hosting?
For reference data and European clients, OVH/Scaleway hosting (90-200 USD/month) reassures on compliance and improves latency via CDN.
What is the real timeline?
6 to 9 weeks, but the bottleneck is usually internal content sign-off and reference supply. Appoint a project lead on the consultancy side.
How do I compare tender quotes?
Impose an identical brief: page count, languages, CMS, reference volume. Otherwise the prices are not comparable.
