Stability Project: Foundation and Structural Safety

The stability project is a technical study aimed at sizing and verifying the structural elements of a building, whether new or existing. This process involves a thorough analysis, considering technical and regulatory requirements to ensure that the structure can support the expected loads, such as its own weight, wind, snow, and seismic actions. The work is developed and signed by a qualified civil engineer.

In addition, the structural project includes the sizing of foundations, selection of construction materials, waterproofing, and detailing of slabs, beams, columns, and load-bearing walls, according to the chosen structural system. The primary goal is to ensure the safety and integrity of the building throughout its lifespan.

Elements of a Stability Project

The stability project consists of written documents and technical drawings submitted to the City Council for licensing or prior communication, in accordance with the applicable administrative procedure. The elements include:

Responsibility statement from the responsible engineer.
Declaration from the engineer’s professional order, proving their qualification.
Written pieces, such as a descriptive report, calculation justifications, and budget estimate.
Drawn pieces, including general plans and technical details in different scales (1/100, 1/10).
Other relevant documents, depending on the project's complexity.

The stability project is always based on the architectural project, and continuous collaboration between engineers and architects is essential to adjust the structural solutions to the project's needs.

When is a Stability Project Necessary?

A stability project is essential in the following cases:

New constructions: Buildings or homes yet to be built.
Structural modifications: Changes to existing properties that affect the structure, such as renovations and rehabilitations.
Legalizations: Works carried out without prior approval that impact the load-bearing structure.

It is crucial that the architectural project is already prepared before starting the stability project, which can be developed simultaneously or after architectural approval.

Structure of a Stability Project

A stability project consists of the following stages:

Load Analysis: Detailed assessment of permanent and variable loads (wind, snow, seismic forces).
Material Selection: Definition of materials to be used, such as concrete, steel, or wood.
Structure Design: Sizing of columns, beams, foundations, and other structural elements.
Technical Detailing: Structural calculations, joints, welding, and fastenings.
Foundations: Detailed information about the type and dimensions of the foundations.
Safety: Implementation of measures to protect workers and avoid accidents.
Budget: Detailed cost estimation.

The report may also include seismic vulnerability analysis and recommendations for structural reinforcement when necessary.

Relation to the Architectural Project

The stability project is intrinsically linked to the architecture, which defines the design and functionality of the space. Civil engineers ensure the structural feasibility of these ideas, adapting technical solutions to meet both aesthetic and safety requirements.

The involvement of the civil engineer from the early stages of the project is essential to ensure a harmonious integration between the structure and the architectural design.

Applications in Different Types of Works

Stability and peripheral containment projects are applicable in various situations:

New constructions: Ensure structural safety from the design phase, including excavation and containment projects for basements or deep foundations.
Remodeling: Assess the existing structural capacity and propose necessary reinforcements or modifications.
Rehabilitation: In old buildings, identify structural damage and suggest reinforcement or replacement solutions.

Collaboration between architects and engineers is crucial to align structural issues with aesthetic and functional demands.

Excavation and Peripheral Containment Project

This project is a detailed technical study that evaluates soil stability and defines measures to prevent landslides during excavation. It is essential for works involving basements, substructures, or deep foundations.

Project Structure:

Geotechnical Analysis: Study of soil characteristics.
Excavation Design: Definition of depth, width, and excavation methods.
Containment Systems: Specification of solutions such as anchors and retaining walls.
Technical Details: Drawings and specifications to guide execution.
Timeline and Budget: Planning and cost estimation.
Safety Measures: Protection for workers and nearby areas.

These projects are developed by specialized engineers, ensuring the safety and stability of the construction.
