VOB Tender for Fibre Rollout: Performance Specification and Requirements

VOB-compliant tenders for fibre rollout require precisely structured performance specifications: network operators and municipalities establish the technical and legal foundations for high-quality FTTH civil works projects.

In 2026, VOB-compliant tenders reach new scale: projects such as the NE4 fibre rollout Bremen with EUR 2 million contract volume or the FTTH installation Munich for EUR 4.4 million demonstrate substantial opportunities for qualified civil contractors. The new VDE guideline 0800-730 further simplifies building installation and accelerates implementation before the federal transposition of the EU Gigabit Infrastructure Act.

Performance Specification for Fibre Rollout: Structure and Core Elements

A professional performance specification for FTTH civil works is divided into clearly defined line items. These cover civil works, cable laying, splicing operations and installation of network distribution components. Each item must be tendered according to VOB/C DIN 18365 for fibre cable work.

• Route planning and excavation work with accurate quantity surveys
• Cable laying including duct systems to DIN EN 50173
• Splicing work with attenuation measurement < 0.25 dB
• Installation of network distribution panels and splice boxes
• Documentation to VDE 0800-200 standards
• Acceptance testing with OTDR measurement records

Modern tenders increasingly demand modular systems with high fibre density. Solutions offering up to 96 fibres in 1RU prove effective, optimising limited space in distribution cabinets. Integration of E2000 connectors to IEC 61754-15 ensures highest connection quality in demanding industrial environments.

VOB Requirements for Civil Contractors in FTTH

VOB/A defines strict qualification criteria for bidders in fibre rollout. Evidence of expertise, capability and reliability is mandatory. Current tenders require employer’s liability certificates not older than 6 months plus detailed reference projects.

Qualification Evidence	Requirement	Validity
Technical Qualification	VDE 0800-200 Certification	3 years
Employer’s Liability Certificate	Certificate of Clearance	6 months
Pre-qualification	Entry in PQ Register	1 year
References	Min. 3 FTTH projects > 500 units	5 years
Personnel Evidence	German-speaking skilled labour	Current

The requirement for German-speaking technical staff presents particular challenges for many subcontractors. VOB documentation obligations demand precise communication and comprehensive photographic records of all work stages.

Pricing and Calculation Basis in Fibre Performance Specifications

Calculation for VOB fibre tenders is based on standardised unit rates. Current market prices show clear structure: NE4 rollout is remunerated at EUR 140 per unit, with preparation work at an additional EUR 70 per unit.

• Civil works: EUR 45–65 per trench metre
• Cable laying: EUR 8–12 per metre fibre cable
• Splicing work: EUR 25–35 per splice
• Building connection complete: EUR 800–1,200
• Network distribution installation: EUR 2,500–4,000

System selection rewards quality: modular splice systems with 5-year warranty substantially reduce rework costs. The higher initial investment is recovered through reduced downtime and simplified maintenance.

Technical Specifications in FTTH Civil Works Performance Lists

The performance specification must define precise technical requirements. Central to these are attenuation values, connector types and fibre qualities to ITU-T G.652.D for singlemode applications.

Connector system selection significantly influences long-term stability. While LC connectors are the FTTH standard, E2000 connectors gain importance in industrial applications. Their integrated shutter and IP65 protection rating make them ideal for harsh environments.

Connector Type	Attenuation	Return Loss	Application
LC/APC	< 0.25 dB	> 60 dB	FTTH Standard
SC/APC	< 0.30 dB	> 60 dB	Legacy networks
E2000/APC	< 0.20 dB	> 65 dB	Industrial / Outdoor
MPO/MTP	< 0.35 dB	> 50 dB	High-density cabling

Documentation Requirements under VOB for Fibre Projects

VOB requires complete documentation of all construction work. For fibre projects, this means detailed measurement records, route documentation and splice plans to DIN VDE 0888-100.

• OTDR measurements for every laid fibre
• Georeferenced route documentation
• Photographic record of critical construction stages
• Splice records with attenuation values
• Handover protocols for each building connection
• As-built plans in CAD format

The new VDE guideline 0800-730 simplifies building documentation from 2026 onwards. It establishes uniform standards for transition from public network to building cabling and reduces documentation effort by up to 30 per cent.

Tender Procedures and Award Criteria in FTTH Rollout

VOB-compliant tenders follow a structured award procedure. Following public notice, bidders typically have 4–6 weeks to prepare their bids. Awards are usually made on the basis of the most economically advantageous tender.

Utilities and municipal network operators increasingly favour framework agreements. The LWL 2026/2027 procedure shows the trend towards long-term partnerships with qualified civil contractors. Evaluation follows a weighted scoring system.

• Price: 40–50% weighting
• Technical quality: 25–30% weighting
• Execution time: 15–20% weighting
• References: 10–15% weighting
• Sustainability: 5–10% weighting

Quality Requirements for Splicing Work and Network Components

The quality of splicing work determines the performance of the entire fibre network. The FTTH civil works performance specification defines maximum attenuation of 0.05 dB per splice for singlemode fibres.

Modern splice boxes must provide high fibre density whilst remaining accessible. Systems with up to 96 fibres in 1RU meet these requirements perfectly. The modular design also allows flexible adaptation to growing network demands.

As manufacturer and official Diamond Partner, Fiber Products supplies precision-engineered splice boxes in 1RU form, specifically developed for VOB-compliant tenders. European manufacturing guarantees short lead times and highest quality standards.

Current Market Developments in VOB Fibre Tenders

The German fibre market shows dynamic development in 2026. Major projects such as Hamm with construction start in the second quarter of 2026 or ongoing tenders for 160 kilometres of routes in Pegnitz and Wuppertal shape the market.

• Grey-spot subsidy volume: EUR 3 billion through 2027
• Average project size: 2,000–5,000 units
• Rollout speed: 2 million new FTTH connections annually
• Investment volume DACH region: EUR 8 billion in 2026

Integration of the EU Gigabit Infrastructure Act into German law will further standardise tender procedures. Civil contractors should prepare early for the new requirements.

Challenges and Solutions in Fibre Rollout Performance Specifications

Implementation of VOB fibre projects presents civil contractors with multiple challenges. Unclear route planning in existing buildings, complex approval procedures and tight labour resources require innovative solutions.

The VDE guideline 0800-730 specifically addresses building issues: “The new VDE guideline creates a technical foundation that simplifies, accelerates and reduces costs of rollout,” according to VDE’s current position.
