THE BAU LÜTZ APPROACH

METHOD

A legible project distinguishes data, assumptions, alternatives, decisions, and responsibilities. Bau Lütz organizes these elements in a process proportionate to the mandate and the actual level of knowledge.

01DATA AND FACTS

We collect documents, surveys, constraints, approvals, site conditions and sources. Every material fact must lead back to evidence, a check or an accountable person.

Why it matters: It distinguishes what we know from what still needs to be verified. Available documents and open questions become a shared framework.

START A PRELIMINARY STUDY →
02ASSUMPTIONS AND ALTERNATIVES

Assumptions remain explicit. We compare scenarios by function, impact, phases, resources, indicative cost, maintenance, risk and missing data before selecting a direction.

Why it matters: It prevents a solution from being chosen too early. Options, consequences, dependencies, and missing data remain comparable.

SCENARIOS AND ALTERNATIVES →
03DECISIONS AND RESPONSIBILITIES

At each step we identify the decision, who owns it, the criteria, timing and consequences. Specialist work begins only under a defined appointment.

Why it matters: It makes clear who decides, when, and on what basis. Every step remains connected to a concrete responsibility.

PROCESS FOR PUBLIC AUTHORITIES →
04OUTPUTS AND TRACEABILITY

Initial frameworks, registers, maps, scenarios, minutes, matrices and dossiers may be produced as the mandate requires. Format and depth are agreed; no output is automatic.

Why it matters: It preserves sources, versions, and choices in a form that can be read and updated by new stakeholders as well.

VERIFICATION METHOD

FROM OBJECTIVE TO EVIDENCE

Every question receives an operational answer

01What needs to improve or become possible?

We define the expected result, the scope, and the conditions that cannot be ignored.

02How will we know whether the project is moving in the right direction?

We identify indicators, sources, and checks proportionate to the decision.

03Which possibilities are realistic?

We compare scenarios while distinguishing data, assumptions, benefits, limits, and risks.

04Who decides, and on what basis?

We make the responsible party, the criteria, and the operational consequences explicit.

05How is the process kept traceable?

We organize deliverables, sources, revisions, and decisions in an updatable dossier.

06Who verifies and updates?

We assign activities and checks to the parties actually appointed.

Question: what needs to improve or become possible? Bau Lütz response: we define the expected result, the scope, and the conditions that cannot be ignored.

02

Question: how will we know whether the project is moving in the right direction? Bau Lütz response: we identify indicators, sources, and checks proportionate to the decision.

03

Question: which possibilities are realistic? Bau Lütz response: we compare scenarios while distinguishing data, assumptions, advantages, limits, and risks.

04

Question: who decides, and on what basis? Bau Lütz response: we make the responsible party, the criteria, and the operational consequences explicit.

05

Question: how is the process kept traceable? Bau Lütz response: we organize deliverables, sources, revisions, and decisions in an updatable dossier.

06
