[ Ingeniería Estructural Plus ]
We calculate differently.
Solutions in structural design and calculation, foundations, pathologies and soils for construction projects, architecture practices and engineering firms. Because no software can solve every structural problem: no tool replaces knowledge.
- No tool replaces knowledge
- Hand calculation · on a single sheet
- No two soils are alike
- Freedom in design
- Structures speak to us

Structural calculation
Design and calculation of structures, including complex and unconventional ones, without compromising your design.
S.02→Foundations
Design and calculation of foundations, including complex and special ones, adapted to your ground.
S.03→Structural pathologies
Diagnosis of hairline cracks, cracks and deformations, and the solution to restore stability.
S.04→Soil and rock mechanics
Characterisation and stress behaviour of the soil or rock on which your project rests.
S.05→Structural damage assessment
Cause of the incident, extent of the damage, its structural nature and its possible insurance cover.
S.06→Civil engineering projects
Structural calculation of bridges, footbridges, retaining walls, dams and tunnels.

The solution is often simpler than you think.
[ 002 ] The method
We are different.
In structural calculation, two plus two does not always make four. We work with living elements and with many variables that are not usually considered and that lead to incorrect calculations time and again.
The Ingeniería Estructural Plus Method, developed by its founder and director, civil engineer Javier Mataix, diagnoses the optimal solution for each structure, adapted to the ground on which it stands. It diagnoses, designs and calculates by hand: if the behaviour of a structure does not fit on a sheet of paper, it will not fit in the computer.
Optimal solution=Knowledge+Calculation theory
- 01
The ground, just as it is
An ‘undisturbed’ sample has undergone changes in moisture and handling, and a generic allowable bearing pressure for the ground is hard to justify. We study the actual soil at each site.
- 02
The loads it will really bear
We model the loads as faithfully as possible. Otherwise, the structure is calculated to withstand loads that differ from the real ones.
- 03
The right calculation theory
Only then do we apply the appropriate theory to the materials, the structural elements and the ground, together with the software tool required.
[ 003 ] Projects
For structures of all kinds.
We have been involved, alone or in collaboration, in very different structural projects. We give you freedom in design and solutions to the structural problems you encounter.
Residential buildings
- Reinforced concrete
- One-way, waffle or solid slab floors
- Steel or composite structures
Special-purpose buildings
- Offices and shopping centres
- Hospitals, hotels and care homes
- Car parks
Civil structures
- Bridges and footbridges
- Flyovers
- Retaining walls and silos
Industrial structures
- Industrial buildings
- Trusses and lattice structures
- Industrial plants
We work for developers, contractors, architecture practices and engineering firms, and for private individuals who need to solve a problem in their building. Throughout Spain.
[ 004 ] Guides
What you should know.
We explain in plain language the structural problems we come across every day.
Cracks and hairline cracks: when they point to a structural problem
How to tell an unimportant hairline crack from a sign of damage to the structure, and what to do in each case.
Guide 02→Structural damage and the decennial guarantee
What damage the decennial guarantee covers, why exceeding the limits of the Technical Building Code is not enough and how it is proven.
Guide 03→Deep foundations and decennial insurance
Why piles are used, why insurers regard them as an aggravating factor and how their construction is supervised.
[ 005 ] Frequently asked questions
What we are often asked.
01Is structural calculation just a matter of entering data into a software program?
No. Calculation software is a support tool, but it has no overall view and does not understand each particular situation. Knowing how to use an application is one thing; having the knowledge of continuum mechanics, theory of structures and soil mechanics needed to calculate a structure is quite another. Just as a saw is not a carpenter, a program is not a structural engineer.
02What services do you offer?
Structural design and calculation (including complex and unconventional structures), design and calculation of foundations, study of structural pathologies, soil and rock mechanics, structural damage assessment and structural calculation for civil engineering projects. Through Grupo Octplus we also offer complementary services such as technical control of the works and geotechnical reports.
03What types of project do you work on?
We have been involved, alone or in collaboration, in a wide variety of projects:
- Concrete residential buildings, with one-way, waffle or solid slab floors, and steel or composite structures.
- Special-purpose buildings: offices, hospitals, hotels, care homes, car parks or shopping centres.
- Civil structures: bridges, footbridges, flyovers or silos.
- Industrial structures: industrial buildings, trusses, lattice structures and industrial plants.
04Do you work with architecture practices and engineering firms?
Yes. We bring the experience of a structural calculation specialist to architecture practices, engineering firms, developers and contractors, as well as to private individuals who need to solve a problem in their building. We become part of the project team and keep you informed of progress at all times.
05When does a hairline crack indicate a structural problem?
It warrants a technical inspection when it affects beams, columns, floor slabs or load-bearing walls, when it runs diagonally near doors and windows, when it keeps growing or when it is accompanied by deformations such as doors that no longer close. We explain this in the guide hairline cracks and cracks.
06Why is it so important to know the ground?
Because the soil is the ultimate support of the structure and no two soils are alike. A design based on generic ground values can lead to oversized foundations or, worse, inadequate ones. That is why we study the stress mechanics of the soil or rock at each site before designing its foundations.
07What is a structural damage assessment?
It is the study that determines why a structure has been damaged or has failed, the extent of the damage, whether it is structural and what insurance cover and liabilities may apply. We combine on-site measurement of the deformations with their analysis in the office. More information in the guide structural damage and the decennial guarantee.
08Do you work throughout Spain?
Yes. Our engineers carry out projects throughout Spain, maintaining a close relationship with each client throughout the process.
