Visornets’ first Provisional Retention System (SRP) project gets underway in Tarragona
The first construction site to use the Provisional Retention System (SRP) is now a reality in Tarragona, a milestone that marks a turning point in fall protection for workers at height during structural works.
The construction sector in Catalonia is moving towards a more demanding health and safety model, and this site in Tarragona is the first to feature the technology of Visor Fall Arrest Nets, an international benchmark in safety nets and collective protection equipment.
The challenge was clear: protect workers during the most critical stages of the build — structure and cladding — without giving up the fast, agile installation the pace of a site demands.
Tarragona introduces the Temporary Retention System on site
The Catalan construction sector marks a significant milestone: the launch of the first site to install the SRP system in the province of Tarragona. It is a firm step towards a more robust health and safety model, at a time when the structural and cladding phases still account for much of the fall-from-height risk in the sector.
This pioneering project features the technology of Visor Fall Arrest Nets, an internationally recognised company in safety nets and collective protection systems, bringing a technical approach focused on actively preventing falls of both people and objects.
What is the SRP system, and how does it differ from a traditional perimeter enclosure?
The SRP (Temporary Retention System) for building works is an advanced technical solution designed to maximise safety during work at height, with particular application during the structural and cladding phases of a building — the stages of greatest fall exposure throughout the entire project.
Unlike conventional perimeter enclosures, the SRP system combines high-strength rigid metal elements with impact-absorbing technical textiles, creating a continuous, robust barrier that gives peace of mind to both site workers and developers.
Our response was to develop a modular system able to adapt to any site geometry without compromising the continuity of protection.
The components that make the SRP system possible
The versatility and efficiency of the Temporary Retention System rely on a set of fully integrated modular components, designed to adapt to the specifics of any architectural project. These are the core elements deployed on the Tarragona site:
Guardrail + safety net
The main perimeter barrier that safely arrests any fall attempt.
Bracket
The projecting structural support that holds the system frame on the slab.
Bracket extension
Extends the bracket’s radius or reach according to the requirements of the perimeter.
Top rail (3 metres)
The longitudinal top bar that stabilises the enclosure and maintains the tension of the safety net.
Starter rail (1.5 metres)
The horizontal base element used to start the assembly of the protection module.
Brace
A key bracing component that gives the assembly rigidity and prevents structural deformation.
Hinge
Allows the system to pivot, adapting dynamically to the movements of each construction phase.
Omega bracket and omega extension
Geometric fixing components that ensure a perfect fit of the structure.
Guardrail bracket
A dedicated anchor designed for the handrails and safety guardrails.
Toe board support
A robust fixing for the lower containment that stops objects and tools from falling.
Corner toe board plate
An angled piece that ensures the protective toe board runs continuously around the corners of the structure.
Lower guardrail and toe board hook
A connection and low fixing point that optimises the tension of the perimeter net.
Pulley and rung
Elements that make lifting manoeuvres, technical positioning and safe access easier.
Corner bracket lifting base
A reinforced lifting support adapted for critical corner slab areas.
Starter rail extension
A complementary module that safely extends the starting area of the assembly.
ITECAM: the certification behind the system's reliability
The reliability of the SRP system is not a promise — it is a fact backed by industrial science. The system is rigorously certified by ITECAM, guaranteeing strict compliance with current safety regulations and optimum performance in the event of any risk or impact on site.
Why the SRP system makes a difference during the structural and cladding phases
Beyond its components, the real value of the SRP system is measured in the benefits it delivers day to day on the Tarragona site:
Comprehensive collective protection
Protects every worker on the floor at once, without relying solely on individual lifelines.
Faster installation on site
Thanks to advanced mechanical components such as pulleys, hinges and modular extensions, assembly and floor changes are carried out quickly, cutting down on downtime.
Effective prevention against falling objects
The systematic use of toe board supports and corner plates stops tools or materials from falling, protecting the outer and lower perimeter of the building.
Frequently asked questions about the SRP system
What does SRP stand for in construction?
Why does ITECAM certification matter?
Can the SRP system be adapted to buildings with complex geometries or corners?
Does the SRP system only prevent falls of people?
When safety in work at height is built into a project from day one, the entire build gains in confidence. That is the value the SRP system brings to every critical phase of construction.
