1.1 Design Method Statement
During this design stage, the Consultant shall submit to FCO a statement summarising the method of design including basic data and details of any computer program used.
1.2 Design Standards
All engineering design is to comply with the appropriate British Standards and Codes of Practice. Where there is conflict between British Standards and the Local Standards and Regulations in force in the host country, FCO shall be consulted. Generally the more onerous will be observed. In particular, the design should comply with the following:
(i) BS8110 The Structural use of Concrete (ii) BS5572 Sanitary Pipework
(iii) BS6367 Drainage of Roofs and Paved Areas
(iv) BS6700 Cold Water Services
(v) BS8301 Building Drainage
(vi) BS5950 Structural Use of Steel in Building (vii) BS5268 Structural Use of Timber (viii) BS5268 Structural Use of Masonry (ix) BS6399 Design Loading for Buildings
2.0 Design Criteria for Civil/Structural Engineering
2.1 Structure
2.2 Fire Resistance of Structural Elements To be in accordance with normal requirements.
2.3 Performance Requirements
The design is to meet the following performance requirements:
(a) Loading
The building shall be so designed and constructed as to be stable and robust and the combined dead and imposed loads are transmitted to the ground safely without causing such deflection or deformation of any part of the building that would impair the functioning of the building.
(b) Disproportionate Collapse
The building shall be so designed and constructed that in event of an accident the structure will not be damaged to an extent disproportionate to the cause of the damage. The removal of any column must not lead to the collapse of any part of the structure.
(c) Serviceability
The adequacy of the design is to be examined with respect
to the following:
(i) Building Design Life
(ii) Environment/Conditions of Exposure
(iii) Protection against the ingress of water and moisture vapour
(iv) Durability
(v) Vermin, insect and fungial attack
2.4 Loading Conditions
(a) Imposed Loadings
Office floors generally are to be designed for a minimum imposed uniformly distributed load of 5.0kN/m sq. exclusive of loading from partitions (or as instructed by FCO). Rooms for plant will be designed for a minimum load of 7.5kN/m sq..
(b) The effects of the following should be considered (i) Wind loading
(ii) Seismic loading
(iii) Vehicle impact loading
(iv) Accidental loading
(v) Dynamic loading
(vi) Earth and groundwater pressures
(vii) Surcharge loads on retaining walls
(c) Imposed movements
Consideration is to be given to the effects of the following: (i) Deflection
(ii) Expansion / creep
(iii) Shrinkage
(iv) Subsidence eg; caused by underground workings
(v) Ground heave I settlement
