Construction Faults

• The site personnel can be just as guiltuy of promoting deterioration o building by bad workmanship , inadequate supervision & the substitution of por materials , components or fixings . 
• There is a constant need for stringent control of both the work on site as well as the materials used for constructions . 

1. Control of work on site 

- Carefuyl supervision of building work at all stagesis necessary to complement good design , specifications Y detainling by the designers . 

- There are some diificulties in ensuring workmanship is of an adequate standard due to : 

• Increasing difficulty in recruiting workers with the necessary skills for the construction industry . 
• Lack of properly trained workforce . 
• The increase in the number of ocmpelx projects in recent years requires carefull coordination . 
• There may be an over-emphasis on quantity rather than quiality of construction . 

2. Control of Materials 

- It is necessary that the contractor should arrange for all deliveries & documents to be checked carefully to make sure that the materials deliveted tot he site comply with the specifications or samples . 

- Sometimes it may be desirable to test the samples in adidition to visual checking . 

- Materials which do not compley with the specifications should be rejected 

- The contractor may be tempted to substitute inferior materials rather than have such delays . This should only be allowed with the approval of the designer . 

3. Lack of Maintenance 

- The brief of a new building should be include : 

• Performance requirements 
• Possible change in use 
• Operating requirements 
• Cleaning requirements 
• Maintenance requirements 

-The client's brief for a new building often determines the long-terms maintenance need of the building . 

- It should indicates performance requirements & possible changes in use , as well as the future policy for operating , cleaning & maintaining the building .  

- The designer should provide advice to the client on maintenance mattes so that the performance & druability of the building itself & of the fittings & equipment , can be enhanced . 

- The effects of feterioration can be minimised by a serious commitment toward maintance by the users of the building . 

- The failure to allocate sufficient financial resources for maintenance may have serious implications on the standard of maintenance for the property . 

- The use of inferior materials may accelerate the deterioration of the materials & increase future maintenance costs .
