schedule. These registers are updated continually and reviewed in detail on a monthly basis with Basil Read teams that are working both on and off the island, the St Helena government and the Department for International Development. The project is divided into two phases, namely: Phase I: design and construction of the airport (December 2011 – February 2016) while Phase II entails the operation of the airport (February 2016 – February 2026). The value of the entire project is R4,6-billion and it is on schedule and on budget. With two operating batch plants on the island, Basil Read set up a local laboratory to carry out standard testing on all structural concrete, and soils testing, to make sure it meets specifications. The lab is regularly audited by Soil Lab (an accredited laboratory) to ensure compliance is maintained. Beam and core crushing tests are done off the island by Concrete Testing Services. Health and safety The extreme mountainous and rocky terrain, fast changing adverse weather conditions, initially inexperienced and untrained local work- force and limited medical facilities presents high health and safety

risks. These risks are exasperated by the extended working hours and the diverse cultural workforce that can make communication difficult. Major safety interventions and awareness campaigns, monthly rest periods, daily toolbox talks, weekly and daily rotation of plant operators, provision of safety incentive schemes and certified training initiatives – with zero tolerance to non-compliance – has been adopted to keep the workforce safe, motivated and focused. Since the start of the project in 2011, more than 2,7 million man hours have been worked without a life threatening injury. The environment Small islands are extremely sensitive to outside influences. In planning, extensive consideration was given to environmental impacts. There is an environmental team that deals with noise pollu- tion, air quality and dust, terrestrial ecology, heritage issues and nature conservation. Basil Read also supports a four year programme on habitat resto- ration and landscaping called LEMP (Landscape and Ecology Mitiga- tion Programme). This focuses on providing alternative, indigenous habitats and landscape treatments and aims to reduce and offset the possible loss of habitat and any negative impacts on the landscape
