In contract the essential ingredient to manage are time,cost, quality and safety.
There are some factors that delays delivery.
Time delay
1 contractor limited cause
2 material related cause
3 labour and equipment
4 client
5 contract
6 consultancy
7 external
Cost
factors
flucuation
change in exchange rate
cash flow of project
intrest rate
wastage
cost of new works
project labor cost
Quality
factors
clients
volume of works
breif of client and decision making

DIFFERENT BETWEEN ASPHALT AND BITUMEN
Asphalt is a sticky, black, highly viscious liquid or semi-solid that is present in most crude petroleum.
Bitumen is a mixture of origanic liquid that are highly viscous, black, sticky entirely soluble in carbon disulfide.
Primary different between asphalt is made by the mixing aggregate with bitumen.
PROPERTIES OF ASPHALT
1, Highly compartibility between the polymer asphalts and compound
2, Flexibility to low temperatur
3, Supeiior resistance
4, Durability
USES
ASPHALT
Majorly in road constructions
BITUMEN
Paving roads
Bitumious waterproofing
Roof felt

PHYSICAL PROPERTIES OF MATERIAL
STRENGHT: Ablity of materials to resist deformation
ULTIMATE TENSILE STRENGHT; Maximum resistance to fracture
YEILD STRENGHT; Stress at which perdetermined amount of permanent deformation
MALLEABILITY; Percentage enlongation reported in a tensile test.
is also define as maximum enlongation of the guage lenght divided by the orignal guage last.
Ability of material to enlonged in tension.
DUCTILITY; Ability of material to deform easily upon the application of a tensile force
TOUGHNESS; Is describe the way a material reacts under sudden impacts
HARDNESS; Property that enable materials to resist plastics deformation penetration indentation and scratching.
