What is a Reinforcement Survey?

A reinforcement survey is a non-destructive investigation used to obtain information regarding reinforcing steel contained within an existing concrete structure. Reinforced concrete buildings frequently undergo refurbishment, structural alterations or changes of use many years after their original construction, and detailed reinforcement drawings may not always be available.

Reinforcement surveys can help structural engineers understand the existing construction by investigating reinforcement within selected concrete elements. Depending on the project requirements and survey conditions, information may include reinforcement position, direction, approximate spacing and concrete cover.

Where reasonably obtainable, indicative reinforcement diameter information may also be provided. However, reinforcement congestion, concrete cover, adjacent bars and other site conditions can influence non-destructive diameter estimation, so exact bar size cannot always be confirmed using scanning alone.

Magnitude Geo undertakes reinforcement surveys of reinforced concrete slabs, walls, beams, columns, soffits and accessible foundations throughout London and the Home Counties.

Why are Reinforcement Surveys Important?

Accurate reinforcement information can be essential when structural alterations, refurbishment works or intrusive construction activities are proposed within an existing reinforced concrete structure.

Reinforcing steel forms an important part of the structural system, and modifications carried out without understanding the existing reinforcement arrangement can create unnecessary engineering risk. A reinforcement survey can provide additional information before work begins, allowing structural engineers and contractors to make more informed decisions.

Reinforcement surveys are frequently undertaken before wall removals, new structural openings, extensions, strengthening works, installation of new structural connections, drilling and other alterations to existing concrete elements.

Where original structural information is unavailable or incomplete, non-destructive reinforcement scanning can also provide valuable information regarding the existing construction while avoiding unnecessary damage to the structure.

Reinforcement Size, Spacing & Concrete Cover Surveys

Structural engineers frequently require information regarding reinforcement spacing, concrete cover and the arrangement of reinforcing steel within existing concrete structures.

By systematically scanning selected areas of concrete, repeating reinforcement patterns can often be identified, allowing reinforcement direction and approximate bar spacing to be assessed. Concrete cover information may also be obtained where the reinforcement configuration and survey conditions permit.

Estimating reinforcement diameter using non-destructive methods can be more dependent on site conditions. Concrete cover, adjacent reinforcement, bar congestion and reinforcement configuration can influence the results. Where indicative diameter information is provided, it should therefore be considered alongside the stated survey methodology and limitations.

Our surveys can be tailored around the information required by the structural engineer, focusing on selected slabs, walls, beams, columns or foundations rather than carrying out unnecessary investigation across the entire structure.

GPR Reinforcement Surveys

Ground Penetrating Radar (GPR) is a non-destructive survey technology that can be used to investigate reinforcement and other embedded features within concrete structures.

GPR surveys can assist with identifying reinforcement patterns within slabs, walls, beams and other concrete elements while also providing information regarding additional embedded features such as post-tension cables, conduits and services where conditions permit.

Ground Penetrating Radar is particularly useful where a wider concrete investigation is required beyond reinforcement alone. Survey findings can be interpreted on site and processed further where detailed reporting or reinforcement mapping is required.

For more information about this technology, visit our GPR Survey London page.

Ferroscan Reinforcement Surveys

Ferroscan technology is specifically designed for investigating ferrous reinforcement within concrete and can be particularly useful where reinforcement position, spacing and concrete cover information is required.

The equipment can be moved systematically across accessible concrete surfaces to identify reinforcement patterns within selected survey areas. This information can support structural engineers assessing existing concrete elements before refurbishment or structural modification.

Depending on the project requirements, Ferroscan may be used independently or alongside Ground Penetrating Radar to provide additional reinforcement information.

Visit our Ferroscan Surveys London page for more information about our dedicated Ferroscan services.

Representative Reinforcement Surveys

Large reinforced concrete structures can contain extensive reinforcement across slabs, walls, beams and columns. Undertaking a complete bar-by-bar survey of an entire structure can therefore become time-consuming and costly.

Where a complete reinforcement map is not required, Magnitude Geo can undertake representative reinforcement surveys within strategically selected areas.

Survey locations can be agreed with the structural engineer and focused around critical structural elements, proposed openings, highly loaded locations or areas affected by planned alterations.

This approach can provide meaningful information regarding typical reinforcement direction, approximate spacing, concrete cover and reinforcement arrangement while keeping the investigation proportionate to the project requirements.

Reinforcement Mapping & Survey Drawings

Magnitude Geo provides reinforcement mapping and survey documentation for projects where the identified reinforcement needs to be formally recorded for engineering or construction purposes.

Depending on the project requirements, reinforcement findings can be supplied through annotated photographs, marked-up site plans, technical reports and CAD drawings showing the investigated areas and observed reinforcement patterns.

Reinforcement mapping can support structural engineers assessing existing structures before wall removals, new openings, refurbishment works, strengthening schemes and other alterations to reinforced concrete construction.

For projects focused primarily on locating reinforcing steel before drilling or construction works, visit our Rebar Detection London page.

Reinforcement Surveys Before Drilling, Coring & Structural Alterations

Understanding the reinforcement arrangement before drilling, coring, cutting or modifying reinforced concrete can help reduce the risk of damaging important structural reinforcement.

Magnitude Geo undertakes targeted reinforcement surveys around proposed working locations before drilling, resin anchor installation, new structural connections, wall removals, new openings and other intrusive works.

Detected reinforcement can be marked directly onto accessible concrete surfaces where required, allowing contractors and engineers to consider the reinforcement arrangement before construction activities commence.

Where structural alterations are proposed, reinforcement survey information can also support the structural engineer's assessment of the existing construction and proposed design.

Reinforcement Surveys for Structural Engineers

Magnitude Geo regularly supports structural engineers requiring information regarding existing reinforced concrete structures before refurbishment, alteration or redevelopment works commence.

Surveys can assist where original structural drawings are unavailable, incomplete or where additional verification of the existing construction is required.

Typical applications include wall removals, new structural openings, extensions, strengthening schemes, refurbishment projects, changes of use and investigations associated with proposed increases in structural loading.

Survey locations can be selected around the structural elements most relevant to the engineering assessment, with findings supplied through annotated photographs, reports and CAD drawings where required.
