The verdict in three sentences
For a 12-engineer structural engineering consultancy in Amsterdam, a B2B brochure website that actually generates tender invitations costs between €6,500 and €16,000 excluding VAT in 2026, delivered in 6 to 9 weeks. What makes the difference with developers, architects and industrial clients is a filterable project portfolio of 40 to 80 references and expertise pages (reinforced concrete, steel, timber, renovation) that capture Google searches. A consultation form with drawing upload then turns that traffic into qualified private-sector requests.
What an engineering consultancy website needs in 2026
Your private prospects (developers, design-and-build contractors, industrial owners) choose a consultancy on three criteria: comparable references, responsiveness and visible technical depth. The site must prove all three in under two minutes.
| Level | 2026 budget (excl. VAT) | Timeline | Main content |
|---|---|---|---|
| Essential | €6,500 to €8,500 | 6 weeks | 8 to 10 pages, 20 references, simple form |
| Standard | €8,500 to €12,000 | 7 to 8 weeks | 15 pages, 40 filterable references, expertise pages |
| Advanced | €12,000 to €16,000 | 8 to 9 weeks | 20 to 25 pages, 80 references, drawing upload, careers area |
| Technical copywriting (option) | €1,400 to €2,800 | Within timeline | Project sheets written by a construction copywriter |
| Photography and drone (option) | €900 to €2,200 | Weather dependent | 5 to 10 sites photographed |
| Maintenance | €90 to €250 / month | Ongoing | Updates, backups, adding references |
These are 2026 orders of magnitude for Amsterdam and the Randstad. Large network agencies often charge 25 to 35% more for the same scope.
The filterable portfolio, the commercial core of the site
A developer looking for an engineer for a 60-unit, six-storey residential block wants to see similar projects. The portfolio must therefore filter by building type, material, construction value and assignment (design, detailed engineering, assessment). Each project sheet shows the client (if authorised), floor area, construction value, the assignment and one technical challenge solved.
| Filter or feature | Value for the prospect | Indicative extra cost (excl. VAT) |
|---|---|---|
| Filter by building type (residential, office, industrial, infrastructure) | Find a comparable project in 10 seconds | Included at Standard level |
| Filter by material (concrete, steel, timber, hybrid) | Check a specific skill | Included at Standard level |
| Filter by construction value (under €1M, €1M to €5M, over €5M) | Reassure on capacity | €350 to €700 |
| Map of projects in the Netherlands | Show local roots | €600 to €1,100 |
| Form with drawing upload (PDF, DWG up to 50 MB) | Receive a usable file from the first contact | €700 to €1,700 |
| SEO pages by expertise and by city | Capture "structural engineer Amsterdam", "constructeur Amsterdam" | €170 to €330 per page |
On funding, check the schemes available at the time of the project: Dutch SME digitalisation support and regional innovation vouchers appear periodically. Amounts and conditions change every year, so verify them before signing.
Mini case study
Joost, managing director of a 12-engineer structural consultancy in Amsterdam, earns 80% of revenue from low-margin public contracts. He wants to grow the private share from 20 to 35%. He picks the Advanced level at €14,000 excluding VAT, with 70 references and drawing upload, plus €170 a month of maintenance.
The maths: after six months the site generates 6 private consultation requests a month. At a 20% conversion rate that is about 14 assignments a year. With average fees of €10,500 per assignment, additional revenue reaches €147,000 a year. Even if only a third of these assignments are truly attributable to the site, the €16,040 first-year investment is repaid about three times.
