The verdict in three sentences
For a Munich road and bridge contractor bidding mostly on municipal and state tenders through standard procurement platforms, a well structured German and English brochure site with a project map (15,000 to 45,000 EUR, 2026 market ballpark) does the job. A tender portal with a secure prequalification document area (45,000 to 120,000 EUR) only pays off when you assemble more than 12 prequalification packs a year, often in joint ventures. Whatever you choose, get code and data ownership in writing, or your three year cost can double on the first vendor change.
What each option actually covers
Public clients in Bavaria, from city building departments to the motorway authority, check two things before shortlisting: verifiable references and the right documents at the right moment. A brochure site handles the first. A portal handles both, if someone in the company keeps it alive.
| Criterion | Brochure site | Tender portal |
|---|---|---|
| Initial budget (2026 market ballpark) | 15,000 to 45,000 EUR | 45,000 to 120,000 EUR |
| Referenced projects with map | 30 to 80 public case pages | 30 to 80 public pages plus private files |
| Languages | German and English | German and English, bilingual documents |
| Secure document area | No, PDFs sent by email | Yes, access per client or per tender |
| Time to launch | 8 to 12 weeks | 14 to 24 weeks |
| Monthly maintenance | 250 to 600 EUR | 600 to 1,500 EUR |
| Internal effort | One person, 2 hours a month | One owner, 1 day a week in bid season |
The project map carries the most weight in both cases. A procurement engineer wants, for each structure, the location, span or length, client, contract value band and year of acceptance. Agree on a project template early and start filling it the week you sign: missing case data is the most common reason launches slip.
On compliance, German public sector buyers expect accessible websites, and the Barrierefreiheitsstärkungsgesetz applies to certain private services from mid 2025. A contractor site is usually outside its strict scope, but building to WCAG 2.1 AA costs little at the start and avoids a retrofit. Keep GDPR in mind for any portal login: log access, minimise personal data in CVs and define retention periods.
Three year cost and vendor dependency
| 3 year item (2026 market ballpark) | Brochure site | Tender portal |
|---|---|---|
| Build | 30,000 EUR (mid range) | 80,000 EUR (mid range) |
| Maintenance, 36 months | 14,400 EUR (400 EUR a month) | 36,000 EUR (1,000 EUR a month) |
| Hosting and document storage in the EU | 1,800 EUR | 5,400 EUR |
| Content updates by the vendor | 3,000 EUR | 7,500 EUR |
| Estimated total | 49,200 EUR | 128,900 EUR |
| Vendor lock-in | Low on a standard CMS | High on proprietary code |
| Scalability | Private area can be added later | Extends to site progress or partner extranet |
Two details separate a good portal from a bad one. Permissions first: a client should only see the documents for its tender, and every download should be logged. Exit terms second: ask for a full export of documents and metadata in an open format, with no exit fee.
Which option fits your profile
| Company profile | Recommendation |
|---|---|
| Fewer than 6 prequalification packs a year | Bilingual brochure site, project map, certifications page |
| 6 to 12 packs a year | Brochure site with a simple password protected area |
| More than 12 packs, frequent joint ventures | Tender portal with per tender document rooms |
| Regular work for Deutsche Bahn or motorway authority | Portal with partner access and document versioning |
| No internal web owner | Brochure site, a portal would sit empty |
As a nearshore benchmark, here are Kolonell's prices: a Growth site at 1,830 to 3,050 EUR (1,200,000 to 2,000,000 FCFA), 8 to 12 pages with a blog, delivered in 14 to 21 working days, or Premium at 3,050 to 5,340 EUR (2,000,000 to 3,500,000 FCFA) in 21 to 30 working days. A client area adds 230 EUR (150,000 FCFA) and each extra language 110 EUR (75,000 FCFA). A true document portal with per client permissions falls under a simple custom application at 3,810 to 6,100 EUR (2,500,000 to 4,000,000 FCFA).

Illustrative example: Markus, technical director of a 180 person road and bridge contractor in Munich, assembles 10 prequalification packs a year. Each pack takes an engineer 2.5 days, so 25 days a year. A tidy private area would cut that to 1 day per pack, saving 15 days. At a loaded day rate of 650 EUR, that is 9,750 EUR a year. A brochure site with a private area at about 38,000 EUR beats an 80,000 EUR portal: the 42,000 EUR gap would take more than four years to recover from time savings alone.
FAQ
Is a brochure site enough to get shortlisted by public clients in Bavaria?
Yes for credibility, provided 30 to 80 projects are documented with client, value band and acceptance year. The bid itself still decides, the site simply makes your references quicker to verify.
How long does it take to fill the project map?
Plan 1 to 2 hours per project for photos, coordinates and technical data, so 40 to 80 hours for 40 structures. Start it at contract signature, in parallel with design.
Where should prequalification documents be hosted?
In an EU data centre, with encryption, access logs and daily backups. Managed hosting at 50 to 200 EUR a month covers a few gigabytes of files.
Can we start with a brochure site and add a portal later?
Yes, if the site runs on a standard CMS with a clean project data model. Adding a private area then costs roughly 30 to 40 % of a new portal.
What maintenance budget should a contractor plan?
Around 250 to 600 EUR a month for a brochure site, covering updates, backups and small fixes. A portal needs 600 to 1,500 EUR with access monitoring.
