Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Section 06: Concrete and Steel Works  $_{-}$  2.4 a: In this state the structures shall be assumed empty $_{-}$  2.4 b: In this state the structures shall be assumed full $_{-}$  2.4 c: Different load cases and combinations.  Water Testing State  Load Combination 3.1 (water testing of liquid-retaining structures):  Even though the crack widths normally are calculated in the serviceability limit state only, the max- imum allowed crack width in the state of testing structures for water tightness is 0.20 mm. In this  state the structures should be assumed filled with water to a level of 70% of the height of the nor- mal working level only. Pressure from surrounding soil or ground water must not be taken into ac- count. Relaxation of stressing steel and frictional losses shall be taken into consideration in the design.  The load combinations should be also arranged for building types of structures in accordance with  requirements of load combinations in TS 500.  6.5.5 Calculations  The Contractor has the full responsibility for the structural design calculations.  All acting forces should be calculated based upon the theory of elasticity wherever possible. An ap- proximate assumption of the load distribution is allowed if realistic only. Loads which support the  structures should be stipulated with low values.  1 of 18  6_Vol3_d4.3_Section 6 Concrete and steel works_en_GIR_rev6.docx
