If a worker is employed on a roof having a slope ratio of 8 vertical to 12 horizontal or greater the worker must use a personal fall protection system or personnel safety nets must be used and 38 mm x 140 mm 2 in x 6 in nominal toe holds must be used if the roofing material allows for it Formwork Code of Practice 2016 PN11965 Page 5 of 54 Foreword This Formwork Code of Practice 2016 is an approved code of practice under section 274 of the Work Health and Safety Act 2011 the WHS Act An approved code of practice is a practical guide to achieving the standards of health safety andThe American Concrete Institute Founded in 1904 and headquartered in Farmington Hills Michigan USA the American Concrete Institute is a leading authority and resource worldwide for the development dissemination and adoption of its consensus based standards technical resources educational programs and proven expertise for individuals and organizations A vertical hopper is filled with concrete and released to a horizontal trough by raising a sliding gate The concrete then flows past simulated reinforcing bars and its depth in the trough is measured in two places This test is in use in Europe and by some state Departments of Transportation but does not currently have an ASTM test method 2 ULY 2014 GUIDE TO FORMWORK Formwork drawings should include details of formwork and formwork joints sealing procedures ties size and spacing of framing details of proprietary fittings or systems proposed to be used and bond breakers if used The formwork designer should determine the vertical pour rates for walls columns and other

Safety standards prescribe a variety of mechanical safeguards and procedures for example ladder safety is covered by over 140 regulations and extending a sufficient distance from footings and foundations to permit placing and removal of concrete formwork installation of services other construction and for inspection Adoption of a designed form work of concrete is the form which is designed according to the desired form of any structure to be built so they are many type of form work according to the material made of for example timber plastic steel also they are ACI 347 04 Guide to Formwork for Concrete By م Construction of concrete foundation is divided into number of work activities with specific objectives and completion time for each activity is defined For example marking foundation layout excavations base preparation including leveling and lean concrete placement formwork and then steel placement concrete pouring and curing Tolerances Supply of concrete – the need for tolerances Quality of concrete – edges and alignments Stabilised sand – earthworks quantities Preparation of other than rock surfaces before placing concrete – setting out Concrete blinding layer Site preparation Formwork – topsoil stripping Formwork tiesThe foundation and floor or casting slab should be prepared for concrete placement Formwork is commonly lumber but may be reusable plastic or metal Reinforcement is conventional steel used in other concrete work Lift inserts weld plates and other hardware are all termed embeds and are placed in advance of concrete
