Q1) Designa concrete mixture proportions which will be used for offshore concrete platform.Norway is a world leader on offshore concrete platforms with 1aof the world’s 30 larger offshore concrete structures located on the Norwegian continental shelf. The first of these platforms where the Ekofisk Tank installed in 1974 and the last was Troll gravity based structure installed in 1996. The Sakhalin project is located in a harsh and artic environment where concrete structures have proven excellent characteristics with a minimum of maintenance. 80 mm slump value is required for the Sakhalin project. 28-days concrete characteristic strength is 2bMPa. It is required that no more than 1 test result in 100 will fall below the specified strength. The fine aggregate has a fineness modulus of 2.60 and Zone 3. For Coarse Aggregate (Uncrushed):SSD Bulk Specific Gravity: 2.65, Absorption Capacity: 2.b%, Total Moisture: 1.c% and Dry Rodded Unit Weight: 1345 kg/m³.  For Fine Aggregate (Uncrushed):SSD Bulk Specific Gravity: 2.70, Total Moisture: 3.d% and Free Moisture: 2 %. Cement:  Portland Composite Cement, Specific Gravity: 2.97. For 0.e5 m³of concrete, binder amount is calculated as 120 kg(Use ACI Method of Mix Design)

Sustainable development has become an important part of the lives and aspects of enterprise operations globally and locally. There is a global trend to enhance sustainable practices in all sectors and most especially the construction sectors. In fact, the construction industry is responsible worldwide for the usage of 40% of total energy production, 40% of raw materials and 25% of timber; the use of 16% of water, generates 30- 40% of solid waste and 35-40% of CO2 emissions. The government of Malaysia has introduced the Construction Industry Transformation Programme (CITP) to transform the construction industry from 2016 to 2020. It aims to transform the construction industry through four strategic thrusts: Quality, Safety and Professionalism, Environmental Sustainability, Productivity and Internationalisation

4.A surveyor completes a levelling circuit from a known BM at point A ( RL = 37.730 m). At the end of the survey, the surveyor finds out that the rod person moved the graduated staff before a BS value was taken at the third change point. The levels obtained are as follows: 1.857 ( RL = 37.567 m), (0.983, 0.354), 0.571, 1.011, 2.151, (1.124, x), 0.890, (0.543, 3.178), 3.808.
