What Aeci does

AECI – Arquitectura Construções e Empreendimentos Imobiliários, S.A. is a privately held Portuguese civil construction and real estate development company founded in 2002 and headquartered in Milharado, in the Greater Lisbon area. The company delivers construction, rehabilitation, and engineering services organized across eight categories: public buildings, commercial and industrial spaces, schools and kindergartens, urban requalification, building rehabilitation/restoration/conservation, water supply and sanitation networks, wastewater treatment stations and reservoirs, and residential houses. Its underlying capability is conventional civil engineering — earthworks, structural construction, pipeline networks, and finishing — supported by in-house machinery and equipment that the company describes as "at the technological forefront." AECI serves a dual customer base: the public sector, primarily municipalities in the Lisbon District and surrounding regions (Mafra, Loures, Torres Vedras, Vila Franca de Xira, Caldas da Rainha), and the private sector, including commercial clients (Intermarché, Mafricentro, Dekra, Churrasqueira Povoense) and individual residential customers.

The business operates on a project-based, quote-priced model with no public pricing list. AECI generates revenue through one-time construction contracts won either via direct engagement with private clients or through public tendering with municipal and government entities, and it delivers services directly without distributors or resellers. Its geographic operating footprint is concentrated in Portugal, primarily in the Lisbon District, with extensions to Caldas da Rainha, Évora, and Sintra. The company holds an official Alvará de Construção license from InCI, PME and PME Excelência certifications from IAPMEI (the latter awarded in 2013 and 2014), and has a Quality Certification (Certificação de Qualidade) in process. AECI is independently owned with no disclosed parent, subsidiaries, external funding rounds, or M&A activity, and operates with no public-facing API, mobile application, or disclosed digital product platform — its primary customer-facing digital asset is a WordPress-based portfolio website.
