COATT - Col·legi Oficial de l'Arquitectura Tècnica de Tarragona

What COATT - Col·legi Oficial de l'Arquitectura Tècnica de Tarragona does

COATT - Col·legi Oficial de l'Arquitectura Tècnica de Tarragona is a public-law professional college (Col·legi professional de dret públic) established around 1940 that regulates and represents technical architects (aparejadors, arquitectes tècnics, enginyers d'edificació) in the Tarragona Province of Catalonia, Spain. The organization operates from Tarragona with a staff of approximately 10 employees and holds exclusive statutory authority to certify professional documents (visats) required for the legal practice of technical architecture in the region. It serves three primary segments: individual technical architect members who require affiliation for legal practice, individual citizens seeking qualified professionals for construction or renovation work, and construction companies/developers needing certified technical services.

The organization's service portfolio is delivered through a bundle of digital platforms and core professional services. Core services include digital document certification (Visat Digital), professional advisory on liability insurance and social security (via MUSAAT and PREMAAT partnerships), employment services with public/private job boards, technical area support (subsidies guidance, reference budget calculations, equipment rental), and a documentation center selling technical publications and standards. Digital platforms include the Ondevio telematic services portal for member administration, a Moodle-based virtual classroom for training, the iOBRA tool for real-time construction project documentation, and the Obres amb Garantia referral platform connecting homeowners with member professionals.

Revenue is generated through four primary streams: recurring annual membership fees (Col·legiat Resident, Non-Resident, and Estudiants tiers), transaction-based fees for digital visat certification, training course revenue (in-person and online), and sales from the documentation center botiga. Distribution occurs through direct membership enrollment, self-serve digital platforms, and partner channels including insurance mutuals (MUSAAT, HNA PREMAAT) and financial services (Caixa Enginyers). The organization maintains active presence across website, social media, email bulletins (ENLLAÇ), and professional publications (Revista TAG, Revista Cercha).
