Introduction THE CONCRETE AND CORROSION CONSULTANCY PRACTICE LTD was formed to meet the needs of buildings and structures, owners and managers. A requirement was identified for total independent, specialist consultancy services, not tied in any way to contracting companies or material manufacturers. Our advice is based on knowledge of the defects and the best course of action for the building or structure and our client. The practice is made up of staff totally dedicated to our company and the services we offer with many years experience, gained on projects around the world. Construction is an international and capital intensive activity with infrastructure, homes, trade facilities and utilities constantly being built, renewed and expanded to meet the needs of people and business. However, it is an unfortunate fact that, with the passing of time, all structures will eventually degrade. Structural degradation is often accelerated because of the use of outdated design codes, substandard workmanship, poor quality materials and exposure to a harsh environment. It is well known that integrity of structures can be severely challenged in tropical areas of high humidity, in atmospheres with high concentrations of acidic gas and in marine or salt bearing environments. Structures exposed to such adverse conditions will degrade faster if the initial design did not adequately consider the factors which could impact on durability. Early and on-‐going corrosion and structural surveys of at risk structures will provide structure owners with the data required to make informed decisions regarding the remediation necessary to achieve a cost effective service life extension. As an independent organisation working solely for the owner of the structure and not a contractor, the Concrete & Corrosion Consultancy is uniquely placed to make entirely unbiased reports on structural condition and recommendations for cost effective remediation. Our teams carry out these services across the world from the cold conditions of the arctic countries to the heat of the middle and Far East. We are a dynamic forward thinking practice using the cutting edge of technology, both testing equipment and computer software. Our international range of clients find our approach refreshing and reassuring and in most cases (98% when surveyed) we are called on time and time again to work with repeat clients. We believe that only when in possession of all the relevant information can an informed decision be made regarding a successful repair strategy. Comprehensive informative reports are as important as the testing carried out on site. All reports are in colour, are factual and are supplied in hard copy and CD-‐ROM format. Our technicians are trained in industrial roped access and confined spaces techniques meaning we can inspect, test and make-‐safe buildings and structures quickly and economically without the need for costly access systems.
We h ope you will find this literature informative and interesting
Buildings and Structures Pathology
The Concrete & Corrosion Consultancy Building Pathologists are experienced in determining cause of structural distress in all global environments. Whether the form of distress is due to quality issues, corrosive environments, seismic activity or simple human error The Concrete & Corrosion Consultancy Practice Ltd have the staff, the diagnostic test equipment and the experience to accurately diagnose/quantify causes of distress. The Concrete & Corrosion Consultancy Practice Ltd state of the art analytical laboratory is capable of turning around both high & low volume laboratory testing quickly and competitively. The Concrete & Corrosion Consultancy Practice Ltd offer clients the most comprehensive yet cost effective service available anywhere from a single source. Material/element site samples, whether dust, cores or ‘lumps’, are taken by The Concrete & Corrosion Consultancy Practice Ltd Building Pathologists, referenced on site and put through the in house test laboratory for analysis, thereby assuring clients of a fluid and high quality service throughout the entire process. Laboratory analysis includes, but is not limited to: -‐ Steel/Metals Type identification, corrosion resistance, strength, and chemical analysis. Wood Type identification, quality, hardness, age. Concrete Petrography, micro-‐analysis, carbonation, chloride, compressive strength, chemical analysis, HAC, ASR. Bricks/Mortar Chemical analysis, strength, mix proportions, make-‐up, petrography. Most other built environment materials including coatings, screeds etc are tested and evaluated by our laboratory including failure cause investigation.
ACROSS THE WORLD, FROM HAMBURG TO HONG KONG, marine structures have more to contend with, in respect of performance in a highly aggressive environment, than any other form of structure. Marine/salt water environments are among the most aggressive encountered by reinforced concrete or steel structures. The need to keep jetties and berths in almost constant use often means that maintenance of such structures often has a very low priority. The Concrete & Corrosion Consultancy Practice LTD understand the requirements and have both the experience and in-‐house capabilities to carry out all required tasks both above and below water. Whether the survey type is condition, feasibility, diagnostic, intrusive or NDT all tasks are conducted using The Concrete & Corrosion Consultancy Practice LTD directly employed staff and equipment. The Concrete & Corrosion Consultancy Practice LTD understands the key success factors to be:-‐ • An understanding of the structure and the environment in which it stands. • An understanding of the client’s short, medium and long-‐term requirements, including the need to carry out works without impacting on the day to day operations. • Experience in all forms of distress likely to be encountered and knowledge of remedial measure systems. • Rapid analytical evaluation of element samples in The Concrete & Corrosion Consultancy Practice LTD laboratories The Concrete & Corrosion Consultancy Practice LTD uses it’s dive team or in house developed netting and roped access techniques to access, inspect, test and report on all structural elements above and below water. Surveys can be conducted in sheltered or open water conditions.
Power and Water
The National power and water infrastructure of any country serves as the lifeblood of that country. Any National power and water infrastructure situated in less than favourable climatic environmental conditions runs the risk of corrosion driven failure in the long term. The Concrete & Corrosion Consultancy Practice LTD are expert at determining cause and proposing effective countermeasures. Power Generation & Desalination Plants Combined Power & Desalination plants are generally situated in aggressive environments with high temperatures, high humidity and salt water. Early and constant corrosion monitoring of concrete and steel structures and subsequent data analysis will enable decisions relating to effective counter measures to be taken and the service life of the facility extended. At risk elements of such structures can be the seawater intakes and outfalls, sub structures built into a saline water table and superstructure exposed to windblown sea spray and salt. District Cooling Plants Many district cooling plants in the Middle East were constructed rapidly to meet the fast growing requirements of the region and as such were not always built to the highest standards and, in consequence, distress is now being reported. The Concrete & Corrosion Consultancy Practice LTD can survey utility structures and produce unbiased reports on structural condition, current structure life expectancy, remediation recommendations and service life extension options. Water Treatment and Reservoirs A Nation’s health is dependent on its ability to produce fresh water and also to collect and process sewage safely and efficiently. Unfortunately, process plants for both fresh water and sewage treatment are often subject to damage caused by water borne contaminants or external environmental conditions. The Concrete & Corrosion Consultancy Practice LTD is expert in determining the causes of concrete and steel degradation and proposing remedial strategies which will ensure structure life extension.
Tunnels The Concrete & Corrosion Consultancy Practice LTD is constantly engaged in conducting specialist bridge and tunnel surveys in many differing environments; with contracts commonly being undertaken throughout Asia, Africa and Europe. The Bridge and Tunnel contract types undertaken by The Concrete & Corrosion Consultancy Practice LTD include rapid emergency make-‐safe surveys, full structure condition surveys, diagnostic surveys and upgrade feasibility studies. The Concrete & Corrosion Consultancy Practice LTD bridge/tunnel survey teams carry out over 1000 surveys a year across the world and hold many multi-‐year framework contracts. With its specialist teams, The Concrete & Corrosion Consultancy Practice LTD can access, inspect, test and report on any structure offering significant cost savings using innovative access methods no matter how inaccessible a Clients survey site may appear. Chartered Engineers, Bridge Inspectors, Commercial Dive Teams, Roped Access Technicians are all part of the comprehensive package that The Concrete & Corrosion Consultancy Practice LTD offer Clients in order to provide the most comprehensive service available from a single source. Inspections of structures are carried out to standards required by BD 63/07 and the ICE guide to inspection of underwater structures. The nationally and internationally recognised bridge condition indictor score system is also used in all reports. The Concrete & Corrosion Consultancy Practice LTD install and manage, in the long term, structural monitoring systems that permit Clients to receive real time feedback on structure condition and diagnostic.
Oil, Gas, and Petrochem
A large p roportion of all the oil and gas facilities in the world are situated in environments that present challenges to the use of steel or reinforced concrete. Typically, Oil and Gas facilities will be either constructed at the marine interface or in desert regions, on sabkha soils with a high saline water table. The impact on any steel exposed to such adverse environments is exacerbated if conditions of high temperature and high humidity also exist. No matter where in the world, any Oil and Gas facility, whether up or downstream, or a process plant, constructed in a saline environment will inevitably suffer from chloride induced corrosion to the steel used in construction. Jetties, piers and mooring dolphins used in the oil industry for the necessary purposes of shipping products are particularly at risk from corrosion and the requirement to maintain such structures in a serviceable condition is an imperative. Similarly, shore based installations, often equally at risk from corrosion from windblown salt bearing sabkha dust or a high saline water table need to be maintained in a serviceable state. In such circumstances and working directly for the client, the independent The Concrete & Corrosion Consultancy Practice LTD will survey installations and produce unbiased reports on structural condition, anticipated continuing corrosion rates, current structure life expectancy, remediation recommendations and service life extension options.
Corporate Real Estate
Large property owning companies throughout the world are responsible for the upkeep of a huge portfolio of buildings with those buildings often being located far from the corporate headquarters. Whether as part of pre-‐acquisition, dilapidations, emergency or forward maintenance planning, The Concrete & Corrosion Consultancy Practice LTD condition surveys are designed to incorporate the entire building envelope and structure from roof covering, façade and frame to underground structures such as service areas, basements and car parks. The Concrete & Corrosion Consultancy Practice LTD maintains teams of surveyors and technicians who can be placed anywhere in the world at short notice. Such teams include industrial roped access specialists, who can inspect facades at touching distance quickly and at a fraction of the cost of other forms of access. The insight provided by an in depth structural survey permits The Concrete & Corrosion Consultancy Practice LTD to provide Clients with BIM input compatible reports, Life care Plans and Planned Maintenance Schedules. Major Facilities Management Companies, Government, Private Real Estate Owners and International Banks, all trust and use The Concrete & Corrosion Consultancy Practice LTD to provide feedback on the condition of the properties within their respective portfolio’s.
Shopping Malls & Car Parks FAULT DIAGNOSIS IN RELATION TO LEAKS AND DISTRESS occurring in multi-‐storey car parks, often part of shopping malls, all form part of the range of services The Concrete & Corrosion Consultancy Practice LTD offer in relation to these buildings and structures. The Concrete & Corrosion Consultancy Practice LTD is often called upon to carry out condition surveys as part of dilapidations, feasibility or pre-‐ purchase services. It is an unfortunate fact that large proportion of shopping centres and multi-‐storey car parks around the world were “Design & Build” projects; built on cost grounds without thought for service life. In consequence, many car parks have inherent design flaws including drainage outlets that are above the deck levels preventing adequate water discharge, faulty membranes and poor concrete cover.
The experience gained by The Concrete & Corrosion Consultancy Practice LTD in shopping malls and car park inspection & testing have established the Practice as a leader in independent consultancy field and has consequently led to the management of multi-‐million USD car park refurbishments.
Nuclear Industry The Nuclear industry has been present for many years now and an increasing number of facilities are becoming subject for decommissioning plans. The hazardous nature of the material employed in the nuclear industry requires that the structures utilizing such material during the working life of a facility become subject to a long term decommissioning plan. Typically a decommissioning plan on a nuclear reactor containment structure can extend to 100 years during which that structure must be kept intact and free from corrosive damage. Many nuclear plants, now approaching the decommissioning phase, are situated at the marine interface, locations which by their very nature contribute to the accelerated corrosion of reinforcing steel and consequent damage to concrete structures. Our Managing Director was part of an international specialist team set up for 3 years to visit Nuclear establishments around the world and compile a critical technical compendium to be used by all nuclear authorities as guidelines for inspection, testing, reporting on and maintenance of PFR containment buildings and structures. The Concrete & Corrosion Consultancy Practice LTD also has experience of decontamination grade materials from floors to structural repair/protection materials. The Concrete & Corrosion Consultancy Practice LTD are uniquely placed to provide the assessment and monitoring of nuclear structures to ensure the structural integrity required to prevent breaches and any consequent contamination.
