AI Lab · Zurich

New tools for spatial development.

AI prototypes for municipalities, cantons and planning firms. Tested on real building zones, weighing of interests and value capture cases. What works becomes a tool. What doesn’t, we learn from.

All tools in one place

Ready to use or explained in detail. This is what came out of the lab.

Weighing of Interests AI

AI-assisted weighing of interests under Art. 3 of the Spatial Planning Ordinance with five specialised AI agents (FACTS, PRO, CONTRA, LAW, MODERATOR). Court-proof along eight Federal Supreme Court criteria, Word export.

Liveinteressenabwägung.ch

EIA Screening

AI-assisted screening of whether a project is subject to an environmental impact assessment (EIA). Checked against the Environmental Protection Act and the EIA Ordinance by facility type, thresholds and site factors, with a traceable justification.

Liveuvp.interessenabwaegung.ch

Building Zone Capacity

AI-assisted calculation of building zone capacity for municipalities. Population forecasts (STATPOP), land reserves, densification potential and scenarios according to cantonal structure plan requirements.

Livebauzonenkapazität.ch

Swept Path Tool

Swept paths without a CAD licence: load the base plan as DXF or DWG, click the carriageway centreline, calculate the swept path with the tractrix model (based on VSS SN 640 271a). With VSS standard vehicles, conflict checking against the plan geometry and export as DXF, PDF or PNG.

AI Minutes MINU-AI

Automatic meeting minutes by AI. Upload an audio recording and receive structured minutes – ideal for municipal assemblies, meetings and workshops. GDPR-compliant, hosted in the EU.

Value Capture Levy

Digital calculation of the value capture levy for municipalities (Canton of Zurich). Cantonal levy (rezoning into building zones: 20%) and municipal levy (upzoning and rezoning: 0–40%).

In the lab

Site Analysis

Automated site assessments based on official geodata. Links swisstopo, the PLR cadastre and cantonal GIS data into a structured assessment of parcels and sites.

In the lab

Planning Chat

AI assistant for Swiss planning law. Ask questions in natural language and receive traceable answers on the Spatial Planning Act, the ordinance, cantonal requirements and case law.

In the lab

Report Generation

Professional planning reports at the push of a button. Generates canton-compliant, traceable and exportable reports from planning data, from the baseline analysis to the finished document.

In the lab

Scenarios & Variants

AI-assisted comparison of development scenarios and planning variants for inward development. Compare densification options, use mix and land efficiency in a structured way.

In the lab

Archive Agent

An AI agent that makes planning and administrative archives searchable. Finds decisions, reports, plans and case files in natural language, with source references, instead of digging through folders and PDFs.

In the lab

Proposal Agent

An AI agent for proposals and offers. Searches previous proposals, fee rates and text modules in the company archive and supports the drafting of new offers, consistently and in minutes instead of hours.

This is SPEKTRUM LAB

Experiments, not promises

SPEKTRUM LAB is not a product, it is a place to think. We develop AI prototypes at the intersection of spatial planning, public administration and new technologies. Not everything will work. Some of it surprises us, too.

What emerges here is born from practice and teaching: from municipalities that have to calculate their building zones, from planning firms that document the weighing of interests, from authorities that compute value capture levies. Real problems, real experiments.

What guides how we build

Four principles from the lab

Born from practice

Every tool starts with a real problem from a municipality, a canton or a planning firm. Not with a technology looking for a use case.

Traceable, not a black box

Every statement can be traced to a source: a legal article, a Federal Supreme Court ruling, a geodata set. Results that hold up before authorities and courts.

People decide

AI prepares, structures and calculates. The weighing, the zoning decision and the signature stay with the professionals.

Staying independent

EU hosting, open interfaces, data portability. Solutions without lock-in and without dependence on any single provider.

The tools directly in Claude, ChatGPT & Co.

Through the Model Context Protocol, your AI assistant accesses the services itself. Connect once, then use them in the chat.

Federal geodata: swisstopo & PLR cadastre

Query addresses, parcels, EGRID and PLR cadastre extracts right in the chat.

Frequently asked questions

What is SPEKTRUM LAB, and what is SPEKTRUM Partner GmbH?
SPEKTRUM LAB is the experimental unit of SPEKTRUM Partner GmbH in Zurich. The firm advises on spatial and urban planning; the lab turns that work into AI prototypes. What proves itself becomes a tool.
Can I use the tools directly?
Yes. Weighing of Interests AI, EIA Screening, Building Zone Capacity, the Swept Path Tool and MINU-AI are live and reachable via the cards above. The remaining tools are under development in the lab.
What does the MCP server cost?
SPEKT-AI is free. All services together are available in the full subscription for CHF 98 per month. Details under Access & prices.
Where is the data processed?
On servers in Europe. Language models are connected via EU hosting. With the agents, your own documents stay in your repository and are never used for training.
Are the results legally robust?
The tools deliver traceable, source-based groundwork, for example along the eight Federal Supreme Court criteria for weighing interests. The professional assessment and the decision remain with the responsible experts.
Can I have an agent for my firm?
Yes. The Archive Agent and the Proposal Agent are set up on your own document repository. The first step is a conversation about data storage and permissions. Get in touch via spekt.ch/kontakt or info@spekt.ch.

Still have questions?
