We protect your interests on every contract — technical control, schedule, cost and quality, from design to final acceptance. Over 25 years building and supervising.
JAC Engenharia e Construções has operated in the construction and real-estate development market since 2001, known for the quality of its work and for delivering projects on time.
It is run by civil engineers who combine decades of on-site experience with continuous updating of construction and management techniques. We began operating in Portugal in 2017, where we now focus on technical site supervision, contract management and engineering consulting.
Since 2020, JAC Engenharia in Brazil has operated under new ownership, having been sold. The Portugal-based JAC Engenharia has no link or relationship with the activities carried out in Brazil.
From technical supervision to contract management and drone surveying, we cover the full life cycle of an engineering project.
Ensuring the works match the design, bill of quantities, technical regulations and contract. Inspections, testing and provisional/final acceptance surveys.
Core activitySchedules and critical path, S-curves, measurement statements, invoicing, price revision and management of additional and omitted works. Productivity and deadline control.
Cost & scheduleTechnical support on Portuguese regulations (RJUE, RGEU, REH/RECS, fire safety, acoustics, accessibility) and disciplines — structures, HVAC, plumbing, electrical, telecoms and gas.
Decision supportModel checking, clash detection and model-based execution verification. 4D planning and 5D cost control to catch conflicts before they reach the site.
TechnologyDrone aerial photogrammetry — orthomosaic, digital terrain and surface models, contour lines and point clouds, with quality control via GCPs and RMSE.
Aerial surveyOur origin: residential construction — from high-end to affordable housing — and infrastructure such as water treatment plants, reservoirs, mains and power substations.
HeritageDevelopments promoted by Red Dot and supervised by JAC in Vila Nova de Gaia.
