Continuous investments in housing, offices, railways, airlines and road networks have an impact on how your business operates. As a building contractor in construction and/or infrastructure, you'll have to comply with a large number of regulations and quality requirements for construction products, equipment and processes. Furthermore, you must abide by (occupational) health & safety and environmental legislation, while employees must be qualified and competent. Developments in (European) legislation and regulations, increasing international competition, new contract forms and deregulation mean you'll face an increasing number of complex quality challenges. Kiwa can help and support you in every step of the construction chain, offering solutions to all quality-related issues, from certification, quality control and assurance to testing, inspection and risk analyses. We help you avoid drawbacks and claims while increasing cost savings.
