Eurocode Implementation• 1 April 2013 - Eurocodes will be accepted and co-exist for two years with the current Singapore/British Standards.

• 1 April 2015 - Eurocodes will be the only prescribed structural design standards.

• Singapore has adopted the EC7 UK national annex.

Why Singapore Adopts Eurocodes?Singapore's structural building codes are currently based on the British Standards.

Britain migrated to the Eurocodes in March 2010, and since then the British Standards Institution no longer maintains and updates these British Standards.

The Commissioner of Building Control, BCA, commented, "One of BCA's mission is to shape a safe built environment in Singapore. In moving from the British Standards to the Eurocodes, we now have a set of building codes that is constantly reviewed at an international platform and regularly updated to suit developments in the building industry. For Singaporeans, we'll live, work, play and learn in a safer built environment, comparable to many cities from the EU.

Benefits of EurocodesThe Eurocodes is considered one of the world's most technically advanced design standards.

It is based on the collective expertise of professionals from the European Union.

It allows each country to introduce National Annex which specifies parameters to customise its local requirements.

It provides opportunities for the building professionals to import and export design expertise and products.

The Eurocode clauses are structured in a slightly different way in that they contain principles that must be satisfied and application rules that offer a way of satisfying the principles. This is intended to stimulate innovation. The Eurocodes are also less prescriptive than the British Standards, with more aspects left open to the designer.

Retaining Structures Design

• ULS numerical modelling

• Factoring soft clay undrained strength (γcu = 1.4)

• One strut failure

Pile Design

• Current prescriptive design method

• Allowable structural pile capacity shall not exceed 7.5MPa

• NSF, depth to neutral plane 0.6Ls for friction piles and 1.0Ls for end bearing piles.
