STRUCTURAL REHABILITATION AND RETROFITTING DESIGN

Our team of experienced structural and site engineers helps in bringing new life into aging and in distress structures, enhancing their strength and resilience, and ensuring safety. We prioritize practical, cost-effective solutions for rehabilitation or retrofitting/strengthening design, always considering the structural and economic feasibility, tailored to the evolving needs of buildings."

STRUCTURAL DESIGN AND ANALYSIS

Our highly skilled team of structural engineers excels in conducting structural analysis of the existing buildings by creating a 3D model using state-of-the-art software like ETABS, Staad Pro, SAP or equivalent. These models are tested against international standards, including AISC, ASCE, UBC, and IBC subjected to live, dead, superimposed, vibratory, wind, drift, and seismic loads. Our mission includes designing steel and RCC structures that prioritize strength, serviceability, and economic efficiency, delivering results that meet your needs and exceed your expectations.

An experienced BSL team can perform Asbestos-Containing Building Material (ACBM) and Asbestos-Containing Material (ACM) inspection surveys of buildings or structures that are to be remodeled or renovated. The need for an asbestos survey arises when buildings or structures require rehabilitation or retrofitting. It is essential to identify the location and quantity of ACM and Presumed Asbestos-Containing Material (PACM) to protect employees from potential health hazards due to asbestos exposure. The survey is conducted under the guidelines of ASTM E2356.

Apart from a proper design, the essence of successful execution of retrofitting, repair and rehabilitation of concrete and steel structures depends on selection of suitable and compatible materials, methodology for works under the strict guidelines of international standards. If any aspect in the execution of work is compromised or overlooked, then the whole process will bring exactly opposite results in terms of financial and time loss.

Building Standards Limited has state-of-the-art equipment and expertise to inspect the concrete and steel structures and issue stability certification for building structures in compliance with necessary engineering and legal requirements. Our Engineers can perform structural analysis on structures in distress and perform preliminary and detailed investigations of a structure prior to rehabilitation. Building standards have an experienced team of professionals that can perform quality assurance work with required testing services after rehabilitation / retrofitting works have been performed.

Structural audit and evaluation are required when the life of concrete and steel structures exceeds a certain time limit or when structures are exposed to physical damage that causes distress. It is also needed when prolonged exposure to deleterious and corrosive environment causes material deterioration resulting in a deficiency of the structure s ability to withstand existing loading. The need for structural evaluation also arises when the improved performance of the building structure is required to meet the desired functional change in the building structure. Building Standards Limited has the expertise and technical strength to meet the client requirement for improved structural performance in an economical and efficient manner.

PROTECTION OF FOUNDATIONS BY SOIL STABILIZATION METHOD.

BSL can provide economical solutions in accordance with international standards to improve the engineering properties of soil to mitigate the potential damage caused by the use of unsuitable soils in foundations. Most soils used as backfill materials are obtained from nearby riverbed that carry untreated wastewater from industries and other chemical pollutants from city wastewater. This can result in efflorescence in brick masonry foundations and is a major cause of deterioration of concrete and steel in subsoil RCC structures. BSL offers cheap soil stabilization techniques for long-term durability and protection for brick and concrete in contact with soil for residential, commercial, and industrial buildings.

Capo test is a post-installed pull-out test with ASTM Designation C-900 and Euro Standard EN 12504-3 performed to obtain a reliable estimate of in-place compressive strength of concrete. Capo test is an excellent choice for structural assessment of compressive strength of concrete where concrete cores are difficult to obtain and at places where damages to steel reinforcement can be highly critical especially in bridges with the carbonated surface layer.

The test is used to determine carbonation depth in concrete structures that have suffered or may suffer damage or deterioration due to calcite and other alkali-carbonate products resulting from exposure to moisture and chemical attack. Presence of oxygen and moisture due to carbonation results in corrosion of embedded steel reinforcement in concrete. This test is used to detect carbonation activity at earlier stages in old concrete structures especially bridges and concrete structures exposed to chemically corrosive environments of fertilizer plants and the textile industry.

Plumbing & Sanitation Works mainly water supply & sewerage works in new construction is most critical as all pipes and fittings are fully or partially covered by the concrete or plaster works. In the bathroom, kitchen & utility areas these services are covered by expensive tiles and similar expensive materials

Once the water supply or sewerage pipe or sanitary fitting/fixture starts leaking or any plumbing fixtures start malfunctioning the entire area is affected with seepage resulting in peeling-off of paints and other architectural finishes. More severe cases of leakages can destroy flooring, wall finishes, outer profile, and can cause destruction of the RCC slab. Accumulation of water can have a disastrous effect on the health of building structures.

BSL offers cost-effective and reliable test services at the construction stage to counter post-construction leakage problems in water supply, sewerage pipes and fittings.
