- Is every requirement linked to a function or an operational need?
- Are supply, installation, programming, testing and handover included?
- What evidence will demonstrate functional equivalence?
- Which exclusions and assumptions must bidders state explicitly?
Tender & Specification Advisory
From requirements to a tender-ready technical solution.


A practical basis for sound decisions.
Good specifications connect the intended function with measurable technical requirements. We help structure the scope so that bidders can price consistently and proposals can be assessed on a common basis.
- Needs assessment and scope definition
- Door schedules and quantity analysis
- Functional specifications
- Technical schedules and bills of quantities
- System comparisons and bid evaluation
- Technical support during procurement
- Clear boundaries for supply, installation, commissioning, training and maintenance
Once the concept needs to become a scope that bidders can understand, price and demonstrate.
Missing quantities, vague interfaces and manufacturer-led wording make offers difficult to compare and leave gaps between trades.
- System-open performance descriptions and structured quantities
- A scope and interface matrix, including programming and handover
- Technical comparison criteria and a register of clarifications
- Agreed requirements and current schedules
- Scope boundaries and procurement stage
- Interfaces, expected evidence and acceptance criteria
One specification.
A matching offer schedule.
Clear position numbers connect technical requirements with the bidder’s offer. Basic scope, additional needs and ongoing services stay distinct.

Selected, translated examples from an EIWTC offer-summary working document. Client details, project quantities and price fields are omitted. This is a structure example, not a complete specification or an offer.
Download the structure example · TXTFive sites. Different technologies. One traceable specification.
How can electronic access control for a water facility and remote sites be specified without committing prematurely to a manufacturer? This fictional example connects door functions, operating procedures, IT, power supply, deliverables and evidence in one structured document.
Already used internally for projects – public access is being prepared.EIWTC already uses the configurator internally to prepare project-specific specifications. Direct self-service access for external users is not yet enabled. Individual project enquiries can already be handled and subjected to professional technical review.

One water facility. Five sites. One coherent approach.
22 doors · 2 gates · 4 additional secured points · 12 lockers. Plus 60 contactless cards and 16 electronic keys; credentials are not counted as locking points.
Five applications. No one-size-fits-all product.
Putting every component on one list is not enough. Every locking technology requires appropriate authorisation, power, communication and failure-handling arrangements.
Wired online entrances and gates
Six doors and two gates at the water facility and pumping station. Frequent use, traceable revocation processes, and separate tests for network and power failure.
Wireless networked door furniture
Six administration rooms with battery-powered electronic handles. Two planned radio zones; radio coverage must be proven on site.
Conventional offline door technology
Four offline double cylinders and two electronic fittings on assumed fire-rated doors. Authorisation periods, service opening and suitability of the complete door assembly require verification.
Key-powered locking components
Four battery-free double cylinders and four electronic padlocks at remote sites. Electronic key validity and update routes shape the operating model.
Electronic locker locks
Personally assigned staff lockers with controlled permissions, service opening and dedicated installation and acceptance tasks.
Not just equipment. Services and responsibilities, too.
The example covers quantities, design, credentials, software and licences, controllers, communication components, cabling, IT and trade coordination, installation, commissioning, training, acceptance and operational services. Price fields are intentionally empty: this is a procurement and estimating framework, not a validated cost calculation.
Describe functionality, thresholds and evidence, rather than prescribing a brand.
Review core components, infrastructure, services and, where relevant, recurring costs together.
Distinguish revocation times, local autonomy, key updates, failure behaviour and responsibilities.

Sample specification – Water supply
The documents are available as a German original and a structured French demonstration edition. Both cover architecture, verification principles and 38 bill items; neither is a ready-to-use tender package.
The French edition covers all 38 bill items, their quantities and the main technical requirements, but is an edited, condensed adaptation rather than an exact or certified translation. The German R10 document remains the reference for the full source wording. Both are fictional examples and are not tender-ready.
Relevant requirements rather than generic lists of standards.
The configurator is being developed around a set of technical, commercial and regulatory checks. For each actual project, only the applicable requirements should be selected.
Which checks and frameworks are considered?
CRTI-B and applicable Luxembourg tender and contract rules; national procurement law and EU procurement directives where relevant.
EN 179, EN 1125 and EN 13637 where applicable; fire and smoke requirements, including evidence for the specific door, lock, fitting and accessory combination.
EN/IEC 60839-11 series, functional suitability and interoperability; defined permissions, communication paths and acceptance criteria.
GDPR, access roles, logging, retention, deletion and authorisation management.
NIS2 and, where applicable, CER for entities in scope; CRA, RED, EMC and, where relevant, the Low Voltage Directive for products. Scope, dates and evidence are evaluated separately.
Backup/restore, security updates, vulnerability handling, end of support, maintenance, documentation and recovery.
Worksite organisation, responsibilities, power, cabling routes and handovers between trades.
Functional equivalence measured against demonstrable features and evidence, without unsupported brand preferences.
This rule base supports project-specific assessment. It does not replace technical suitability checks, legal advice or the necessary manufacturer, fire-safety and security evidence. No automatic NIS2, CRA or GDPR compliance is claimed.

Bring the project.
We help structure the decisions.
Tell us the building’s use, your project phase and the question you need to resolve. Existing plans, a door schedule or a draft specification provide a useful starting point.
We clarify the advice needed and agree the next step with you. Project work may cover a functional concept, technical specifications, tender comparison or coordination through testing and handover.

Discuss your requirements, available documents and next planning decisions. Detailed concepts, specifications and further project support are scoped and quoted separately.
Sending an enquiry does not book a paid appointment. The appointment and its terms are agreed with you beforehand.
