Structural Inspection and Investigation
Investigating structures for faults, poor design and overall structural integrity is vital. Inadequate professional expertise and experience in this area can result in buildings collapsing, and, as the most severe consequence, loss of life. RSK’s long history of delivering structural investigations paired with its expertise and dedication to health and safety means that it is the professional you can trust. With more than 30 years’ experience, we have unparalleled expertise in inspecting and reporting on factual findings.
We carry out more than 1000 inspections a year on a wide variety of structures, ranging from major national landmarks to small culverts on minor roads. Irrespective of size, budget or location, each project receives the same detailed attention by our experienced inspectors, and clients receive a high-quality inspection report tailored to their needs. By employing experienced engineers that are skilled in specialist-access techniques, including rope access, confined space access and pontoon access, we can undertake work in potentially hazardous locations efficiently, safely and professionally.
Innovative solutions and services
We combine the industry experience of our dedicated structures team, and subsidiaries Central Alliance, Ian Farmer Associates, CAN and Up and Under, with emerging and existing technology to solve our clients’ challenges, and our applied technologies division looks at industry challenges from a unique perspective. In collaboration with software company Utilis, we have helped to develop an analysis process for saturated ground mapping. Using technology that is used to source water on other planets, RSK and Utilis are combining their experience and applying the same satellite technology to map relative ground saturation at a higher resolution than ever before.
We undertake surveys and investigations to determine the construction details, methods and condition of a wide variety of structures. The findings from our surveys, which may include laboratory testing, as-built drawings and repair specifications, are collated to provide the information clients need to progress projects. Our services include structural investigations, steel sampling, scans, trial pits and excavations, geotechnical inspections and unmanned aerial vehicle inspections.
Understanding your concerns and meeting challenges
Our clients seek assistance in monitoring, surveying and investigating their assets to either maintain, enhance, upgrade or renew them. They worry about the failure of assets, including structures, and our primary aim is to assure them that we understand their concerns before implementing a bespoke strategy. For example, through voided structure investigations or physical and mechanical testing of concrete, and other materials, we can provide a definite report on the status and stability of a structure. If further work is required, we have the necessary in-house expertise, so you do not have to hire third-party subcontractors, which gives you peace of mind and efficient service.
Expert knowledge readily available
RSK, through its structural inspection specialists, offers vast services covering the spectrum of structural inspections and investigations. We offer general and principal highway inspections, detailed visual railway examinations, buildings surveys and bridge inspections. All our structural investigations are conducted by in-house experts using highly specialist techniques dependent on the nature of the structure and the requirements of the investigation. The structural investigation team specialises in intrusive survey techniques such as diamond coring and drilling techniques. Through the latest non-intrusive techniques, such as muon tomography, we can identify potentially problematic features such as hidden shafts in tunnels, construction voids and hidden critical elements in structures. For an expansive view of a site, we use our unmanned aerial vehicles.
An integrated service
RSK’s full scope of structural inspection and investigative services ensure that it provides bespoke solutions to clients, across all sectors. Our in-house structural maintenance and repair division is ideally placed to deliver a bespoke strategy if further work is required after our in-depth inspection and investigation. Our three decades of experience, coupled with the combined efforts of in-house specialists and sister companies, means we understand that the requirements and conditions of a project can change quickly. We are therefore adept at adapting to circumstances on the ground and advising immediately.
Structural inspection and testing
RSK includes invasive investigation, chemical and non-destructive techniques as part of its inspection and testing procedure. This provides you with a robust analysis of your site to help you make informed decisions.
Site investigation is vital to finding a cost-effective solution to your problem, particularly where there are stability issues. Our investigations offer you a realistic budget and design options for the outcome that is required.
We use conventional and specialised rope access techniques to help you get the best solution where you have difficult-to-reach areas. Cost-effective, efficient and safe, we are the forerunners in this field.
Using the latest in drone and unmanned aerial vehicles, and with a background in structural inspection, RSK can deliver a cost-effective solution to planned maintenance and inspection on your built asset.
We provide laboratory testing of cores and samples recovered from structures.
Voided structures investigations
We undertake expert top-down vertical investigations and CCTV surveys of historic railway viaducts to investigate the condition of construction voids.
Internal and external laser scanning of structures to facilitate condition surveys and design.
Sub-surface laser scanning
Below ground and down-the-hole laser scanning of voids and cavities.
Innovative imaging of structures by detecting cosmic ray muons. This is useful for hidden shaft investigations in tunnels, and investigations for voided structures and hidden critical elements.
IRATA-trained rope access team
Our experts are available for surveys of sensitive or difficult-to-access sites.
We provide chemical analysis of a range of construction materials, including concrete, mortar, render/plaster, bricks and paint to establish a range of properties such as composition or the presence of deleterious materials.
Physical and mechanical testing
We test concrete, mortar, render, natural and cast stone, roofing slates and tiles, including compressive strength of concrete, slip resistance and abrasion resistance of dimension stone.
Specialist mineralogical and elemental composition analysis
Our specialist mineralogical and elemental composition analysis includes scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF).
Deleterious materials survey
We can identify and evaluate alkali-aggregate reactivity, chlorides, high alumina cement, reinforcement corrosion and sulphates in concrete and calcium silicate bricks.
We provide consultancy during the preconstruction design phase, and of existing buildings, to determine causes of failure and assess suitability for refurbishment works.
Expert witness services support
Our in-house experts are qualified across a range of disciplines, addressing environmental issues, construction and property management, geophysics, and geotechnical engineering.
