Architectural Scope of Works Finishes and facades List of finishes and facades selected by the architect are mostly consists of timber, cement render, glass, ceramic, marble, granite and aluminium. Various consideration and prevention measure has to be taken during the design and especially during construction to avoid problems related to facade such as: i. Cracking ii. Staining/discolouration iii. Sealant failures iv. Efflorescence v. Rising dampness/water penetration vi. Corrosion vii. Buckling/deflection viii.
