For any Construction the Stakeholders Need a Process of Assessment, Repair, Rehabilitation, and Protection:

We provide packages of services in these fields. Practical diagnosis which is evaluating defects that affect the construction over the time.
These defects take place because of the environmental conditions that occur to construction, the aging of the construction, and workability conditions.
We put smart efficient solutions as we put a prognosis.
We specify according to each case: several methods, of using concrete jackets, strengthening of the section by additional steel section, using carbon fiber, using prestressing methods, protecting the existing structure……. etc.
We have to check documents of structure over its history and study all its conditions. Several assessment procedures are to be proposed in standards and guidelines. Then we give our proposed advice.
The purpose of assessment of an existing structure should be to ensure that the integrity of the structure is still acceptable, even though it may be in a degraded state. In order to achieve this, several assessment procedures are proposed in standards and guidelines.
We are interested in construction assessment to give the client how to take a decision concerning aging of structure, rehabilitation and life-extension of the structure.
We are making the needed structural analysis before and after repair according. Then we can make the check of design according to a certain code.

The Domain of Intervention for “Retrofitting of Structural Elements” Includes

Local or overall modification of damaged or undamaged elements (repair strengthening or full replacement), considering the stiffness, strength and/or ductility of these elements. Addition of new structural elements (e.g., bracings or infill walls; steel, timber or reinforced concrete belts in masonry construction; etc.).
Modification of the structural system (elimination of some structural joints; widening of joints; elimination of vulnerable elements; modification into more regular and/or more ductile arrangements).
Addition of a new structural system to sustain some or all of the entire seismic action.
Possible transformation of existing non-structural elements into structural elements.
Introduction of passive protection devices through dissipative bracing or base isolation.
Restriction or change of use of the building.
Partial, safe demolition.

Monitoring Policy and Inspection Process

Deterioration of Reinforced-concrete Structures

Causes of Deterioration of Reinforced-concrete Structures

The Protection of Structure Against Water, Heat, Vibration and Erosion:

We give up to date modern solutions using economic, convenient materials.
Repair and rehabilitation of actual failed or low performed water proofing.
Repair of heat insulation of increase the insulation ability against heat.
Protection against vibration.
Sound insulation and the protection against echoes.
Generally, one of the most important protections for the significant constructions is the protection against corrosion to have a long live structure which resist aging. We can discuss the solutions for that to obtain the optimum solution for a certain construction.

How to Mitigate Structures’ Ageing:

1-Regular inspections have to be done.
2- Structural Monitoring.
3- Mitigation of Damaging.
4- Mitigation of Corrosion Damages.
5- Protection System.
6- Mitigation of Fatigue and Other Damage. Or Fatigue stiffening.

Requirements of Sustainability:

Are in the three dimensions:

1- Economics
2- Ecology
3- Social values
All of these requirements urgently need concepts of repair & rehabilitation

Some of Inspection Methods We Apply According to Each Case:

• General Visual Inspection:
• Close Visual Inspection:
• Flooded Member Detection:
• Ultrasonic Testing:
• Eddy Current Inspection:
• Magnetic Particle Inspection:
• Alternating Current Potential Drop:
• Strain Monitoring:
• Acoustic Emission Monitoring:
• Leak Detection:
• Air Gap Monitoring:
• Structural Monitoring:
