STRUCTURAL CONSULTANT IN SAUDI ARABIA
For residential, commercial, and industrial projects, EIWAA is a top structural design consultancy in Saudi Arabia that specializes in creative, robust, and accurate structural solutions. Our team offers effective solutions for all structural issues as well as comprehensive inspection services. Core cutting and concrete coring, pull-out testing, half-cell potential measurement, carbonation depth measurement, and concrete strengthening testing for structural integrity assessment are some of the third-party concrete testing services that we offer. We generates condition reports about the overall condition of the facility and performs condition surveys, facility and Assets Condition Assessments (BCA) with external evaluations. Our Asset Structural Assessment report contains an entire summary of the non-intrusive survey’s results and recommendations given to the customer.
To understand the physical state, structural integrity assessment, and life expectancy of the facility and assets, EIWAA performs facility and asset state assessments, assigns Facility and Assets Condition Index values, and prepares a report for the designated list of properties. We provide the Facility Condition Index (FCI) to represent the facilities and their component parts in their as-built condition.We are the top concrete cutting company owing to our concrete core drilling and core cutting services in Saudi arabia, which include concrete cutting, wall and floor sawing, concrete demolition, concrete drilling and coring, concrete repair, and more. Concrete scanning, half-cell potential measurement, and carbonation depth measurement are all included in the concrete inspection and testing services.
In collaboration with the client, our structural assessment services in Saudi arabia involve a field evaluation and investigation plan that will gather all relevant information on the current structure. The as-built geometry, building materials, and current state of the structure will all be covered by our Visual Field Assessment and Condition Survey services. The following fieldwork will be carried out to gather as much information as possible from present circumstances and to identify and assess the kind, causes, and degree of material deterioration and condition.
- Observing the building's structural characteristics and identifying the load-bearing components.
- A visual inspection of the subsurface or basement water supply and drainage systems.
- As needed, measurements of the site's structural components (column, slabs, beam, wall, foundation, etc.) are taken.
- Determining the state of the slabs, beams, columns, and other construction elements.
- Examining the state of the subsoil.
- Documenting any obvious indications of distress, such as corrosion, overloading, or cracks, as well as evidence of degradation.
- Determining the loads that the structure is exposed to.
- Verifying the walls' verticality and plumpness as needed
- 3D laser scanning of the current state of the building
CONCRETE CORING SERVICES
The Building As-built Survey and Building Condition Survey are used to evaluate the entire structure, including the underground elements, as part of our Building Integrity Study in Saudi arabia. Existing structures’ concrete strength must be evaluated in accordance with ACI-562 and ACI-563 or BSI 6089-1981. Materials other than concrete will be studied using advanced investigative techniques. These methods could involve opening or removing the building fabric, or they could be non-intrusive. The locations of sample removal and inspection openings must not interfere with the fabric in any way. To provide representative research, sufficient material samples, structural components, and linkages must be analyzed. The following are only a few examples of the field investigation tasks that will be carried out:
- Digging enough trial pits, if necessary, to assess the state of the concrete in the raft and retaining walls and removing concrete cores in accordance with the applicable norms and codes listed below.
- Collect dust samples for chemical testing in the lab and conduct field carbonation tests.
- To ascertain the normal reinforcing cover and an indication of rebar layout, a cover meter study will be conducted at specific sites.
- Conducting a delamination survey to identify any regions where the steel-concrete bond has been compromised.
- Examining the overall state of the reinforcing and concrete. evaluating the extent of reinforcement corrosion at specific sites by contrasting them with the original, undamaged steel bars.
- Visual inspection of structural steel to identify any existing features.
- Using a crack width opening test, the types and geometry of cracks on site are measured. obtaining samples from the walls' lime or cement bricks. Visual inspection of the wood, joinery, and finishes for deterioration and boring insects.
- As needed, conducting SPT tests and boreholes to verify the water level beneath the structure and its bearing capability. documenting the structure’s characteristics and identifying any potential movements of the kinds.
- Verifying member conditions for additional assessments.
- The state of the building materials in the mechanical fasteners and wall members. documenting outward manifestations of discomfort and symptoms of decline. examining the state of electro-potential corrosion.
- Let the lower basement's water run out. Determine and keep an eye on the areas where water is leaking through the retaining walls and foundation.
Carbonation Depth Measurement: The purpose of the phenolphthalein test is to determine how deep the carbonated layer is close to the surface of hardened concrete. It is not appropriate for use with calcium aluminate cement concrete. It can be applied to test specimens, cores, or pieces taken out of hardened concrete structures, both on-site and in the lab. Cement paste has a pH of about 13, which provides a passive layer that prevents corrosion on the steel reinforcement. Passivity begins to decrease at pH 11. Because of the carbon dioxide in the air, the concrete becomes carbonated, which lowers the pH. The depth of carbonation is measured using a phenolphthalein indicator solution, which turns pink when it comes into touch with alkaline concrete with a pH more than 9 and colorless at lower pH levels. Spraying the indication onto freshly exposed concrete surfaces that have been broken off the building or onto split cores is the most widely used technique for conducting the test.
Half-Cell potential: According to ASTM C87, steel corrosion can be assessed using an electrochemical method for Half-Cell Potential (HCP) testing services. This method measures the potential electrical difference between the top steel rebars and a standard portable reference electrode that comes into contact with the concrete surface. The half-cell is composed of either a copper/copper sulphate or a silver/silver chloride cell, however other combinations may also be used. To reduce the possibility of corrosion of the steel reinforcement in the immediate area of the test site, the concrete can be empirically coupled to the observed potential difference as an electrolyte. The positive findings from bridge deck corrosion studies have improved the accuracy of half-cell potential measurement as a measure of corrosion potential.
A half-cell potential survey requires careful planning, measurement, and data correlation in order to accurately assess the corrosion damage of a reinforced concrete building. It is usually advisable to confirm the half-cell potential data using additional testing methods prior to interpreting the corrosion likelihood. For evaluating field corrosion, the half-cell potential methodology is commonly combined with a number of other methods, including visual inspection, delamination surveying, measuring chloride content, measuring concrete resistance, performing a concrete cover-depth survey, figuring out carbonation profiles, etc.
