What Smit Groenadvies does

Smit Groenadvies B.V. is a Dutch professional services consultancy specializing in landscape design, spatial planning, and ecological management for green spaces, headquartered in Schagen with a secondary office in Purmerend. The firm delivers advisory and engineering services across seven integrated divisions covering green advisory, ecology (now branded Prommenz Ecologie as of July 2026), landscape architecture (Buro Mien Ruys), infrastructure, space and development, environmental services, and surveying. Core technical capabilities include GIS-based ecological survey and inventory systems (e.g., elm disease tracking for Gemeente Hollands Kroon), codified field protocols (Quickscan Flora & Fauna, Aanvullend Ecologisch Onderzoek, Ecologisch Werkprotocol), and an innovative nitrogen-freezing technique for Japanese knotweed control developed with Weed Free Service B.V. The firm is ISO 9001 certified.

Smit Groenadvies generates revenue through project-based professional services engagements, with pricing conducted via quotes rather than public rate cards and contracts won through public tenders and direct client relationships. The primary customer segments are Dutch municipalities (including Gemeente Schagen, Aalsmeer, Hollands Kroon, Purmerend), housing corporations (Lieven de Key), water management companies (PWN), and cultural institutions (Stichting Hollandsche Schouwburg), all concentrated within North Holland, Netherlands. The business model is sales-led B2G/B2B, with services addressing compliance with the Dutch Environment Act (Omgevingswet), biodiversity protection during construction and renovation, invasive species management, and sustainable urban development.

Since 2021 Smit Groenadvies has operated as a wholly-owned subsidiary of PrommenzGroup B.V., an integrated advisory and engineering group with 100+ colleagues across multiple divisions including Prommenz B.V., Prommenz Survey Solutions B.V., Prommenz Milieu B.V., and Prommenz Realisaties B.V. The parent has executed a serial acquisition strategy, adding Buro Mien Ruys (2023) and Bouwkundig Adviesbureau SAS plus Hollands Kroon Architectuur (2025). Leadership includes owner Foppe Timmer, project leader Jos Smit, Manager Ecologie Willem Koning, and ecologist Thijs Tijssen. Marketing is conducted via LinkedIn, Facebook, an active blog, and the Prommenz recruitment website.

Products and services

• Quickscan Flora en Fauna Preliminary ecological screening consisting of a desk study (NDFF analysis), field visit, and analysis to determine the potential presence of protected species at a project site. Used by municipalities and developers prior to construction or renovation.
• Aanvullend Ecologisch Onderzoek Detailed field research targeting specific protected species (bats, swifts, house sparrows, martens, birds of prey, natterjack toad, owls) carried out according to fixed periods and established protocols. Used by municipalities and project developers requiring species-specific compliance data.
• Ecologisch Werkprotocol (EWP) Written protocol describing how construction or maintenance works must be executed in relation to protected species present on site, and how disturbance is prevented or limited. Used by contractors and project leads working under the Dutch Environmental Law (Omgevingswet).
• Soortenmanagementplan (SMP) Multi-year plan that combines nature protection with housing renovation or sustainability programs, enabling insulation and renovation of homes without harming protected species. Used by Dutch municipalities coordinating large-scale urban renovation.

• Japanse Duizendknoop Bestrijding Japanese knotweed control service using multiple methods including excavation, covering, thermal freezing (with nitrogen/dry ice), and deployment of pigs in nature areas. Used by housing corporations, municipalities, and project developers needing to prevent property damage from invasive plants.
• Inventarisatie Iepziekte Inventory of elm trees affected by elm disease on private property, conducted using a GIS system for collection and management of reports. Used by municipalities to track and manage removal of diseased elms.
• Vrieskou Methode Japanse Duizendknoop Innovative freezing technique in which dry ice (nitrogen) is placed in metal tubes inserted into the ground to freeze the roots of Japanese knotweed, killing them while preserving native soil life. Developed in collaboration with Weed Free Service B.V. and used by housing corporations and municipalities.
