Demonstration · public data

Technical map of the study area over a satellite image in warm gray tones: urban footprint at the center outlined in bronze, drainage network with a 30-meter strip, hatched steep slopes, stippled native vegetation and contour lines
  1. Step 1 of 5

    Image

    Sentinel-2, September 27, 2026: 11,094 ha around Nova Serrana (Minas Gerais), public data only.

  2. Step 2 of 5

    Relief

    Contour lines every 20 m, from the Copernicus elevation model, at 30 m resolution.

  3. Step 3 of 5

    Drainage

    105.5 km of network inferred from the relief, from headwaters to outlet. Not the official hydrography.

  4. Step 4 of 5

    Constraints

    30 m strip along the inferred drainage, slope of 30% or more and native vegetation mapped in 2024.

  5. Step 5 of 5

    Interferences and alternatives

    134 ha of the strip already urbanized; 5,725 ha with no mapped constraint, where the study of alternatives begins, not where it ends.

Who we work for

For decision-makers responsible for assets where environmental and land constraints materially affect investment and delivery.

Permitting, permit conditions, offsets, land-use constraints and environmental and social risk shape schedule, CAPEX and feasibility. H·MARIZ treats them as decision variables, from the outset.

  • Infrastructure

    Concessions, linear infrastructure and regulated assets.

  • Mining

    Expansions, new facilities and environmental liabilities.

  • Real estate development

    Land subdivisions and developments in constrained areas.

  • Industry

    New facilities, expansions and regulatory compliance.

  • Energy and electrical infrastructure

    Lines and assets where permitting and permit conditions shape delivery and expansion.

  • Investment projects

    Acquisitions and capital-intensive assets.

We also work in other sectors where environmental or land constraints materially shape project decisions.

Applied intelligence

From documents to matrix.

Environmental engineering and regulatory management extended by technology and AI: the reading structures the text and points to the source; the technical responsibility stays with the engineer.

See how we apply it

Demonstration · synthetic documents

  1. Step 1 of 4

    Input

    License, technical opinion, request for information and terms of reference, as they arrive. Here, synthetic documents written for the demonstration.

  2. Step 2 of 4

    Reading

    In each document, the obligation and the deadline are identified in the text, with the source item noted.

  3. Step 3 of 4

    Structuring

    Each obligation becomes a row of the matrix: requirement, source and deadline. What the text does not say stays blank.

  4. Step 4 of 4

    Review

    Each row points to its source passage. The engineer reviews, sets the owner and only then does the matrix become a deliverable.

Capabilities

Six practices, each with its own evidence.

Each practice has a page with scope, deliverables and what proves the capability.

  1. Environmental permitting and permit-condition management

    Permitting strategy, studies and permit conditions under control, with technical and institutional engagement with regulators.

  2. Land-use intelligence and geospatial analysis

    Constraints, land tenure and alternative locations, through GIS and remote sensing.

  3. Environmental liabilities and due diligence

    Soil, groundwater and regulatory gaps of land, facilities and assets under acquisition, investment or compliance.

  4. ESG management and environmental and social risk

    Governance, programs, indicators and commitments built for day-to-day operations, not just for reporting.

  5. Management systems and ISO certification

    Implementation, integration, certification readiness and maintenance: ISO 9001, 14001, 45001, 37001 and 37301.

  6. Artificial intelligence applied to engineering

    Structured reading of permits and agency opinions, permit-conditions matrices and traceability, checked by the engineer.
