Planning
01We set out phases, resources, responsibilities, risks and checkpoints.
We carry out building construction, refurbishment and infrastructure maintenance with planning, safety and coordination – on new builds and in spaces that have to keep running.
JAF | Build
That experience spans residential and commercial buildings, industrial units, public infrastructure, refurbishment, maintenance, landscaping, signage, and water and drainage systems. Every job is planned around safety, quality, schedule and fit with its setting.
Each entry leads to the capability that answers it. When a project needs more than one, the same team coordinates them.
Buildings, industrial units and facilities, from the plot to handover.
Restoring, maintaining or changing the use of an existing building.
Water and drainage systems, outdoor areas and signage.
Works in a space that has to keep running, phased and with safety controls.
We build housing, commercial premises, offices and public facilities.
We restore, maintain and adapt existing buildings and heritage properties to new uses.
We carry out preventive, planned and corrective work to keep infrastructure available and performing.
We build, extend and adapt structures for manufacturing, logistics and storage.
We carry out landscaping work, maintain outdoor spaces and install technical and operational signage.
We install and maintain water networks and systems in urban, industrial and infrastructure settings.
Where the drawing becomes a place. Where the calculation becomes structure. Where time becomes handover.
JAF.04 | Operations
In spaces that stay in use, we step up planning, coordination with the client and the management of access, safety, noise, circulation and work phases. Methods are adapted to keep the disruption to existing activity down.

From the technical gesture to handover – welding, masonry, screed and finishes carried out by the in-house teams of JAF Construções.







Four stages that structure every job, from planning to handover.
We set out phases, resources, responsibilities, risks and checkpoints.
We apply the safety procedures that suit the site, the tasks and the operations under way.
We keep the client, site management, the teams, suppliers and the authorities involved in constant contact.
We control execution, keep the document record, close out non-conformities and organise the handover.
The work cuts across residential, commercial, industrial and critical-infrastructure sectors – with team, process and schedule adapted to each setting.
We deliver developments, multi-family housing, refurbishment and building conversions.
We build and refurbish office buildings, hotels, retail units and shared public spaces.
We build and adapt industrial units, production plants, warehouses and supporting infrastructure.
We carry out maintenance, upkeep and works in environments with high operational demands. [ View the dedicated page → ]
We build and refurbish public facilities, public buildings and heritage properties.
We deliver the civil works and support the installation of solar and energy systems. [ View the dedicated page → ]
Projects across different contexts and building types, each with its location, scope and outcome on record.

Residential construction with two independent units, private swimming pools and a layout adapted to the topography of the site.

A residential development in Alcochete, developed by JJF Sul, a Grupo JAF company, and built by JAF.
Real Estate View project →
A corporate project bringing the Group’s companies together in a building designed for collaboration, energy efficiency and identity.
Construction View project →Once handed over, a building consumes energy, can produce it, and needs managing. Those capabilities sit inside the Group, with no change of contact.
Once the works are handed over, the asset starts consuming. Energy supply covers contracting and managing that consumption.
Roofs, car parks and spare land are where solar self-consumption fits without competing for usable space.
When the build is a development rather than a commission, managing and growing the asset continues after handover.
