a contractor behaves like this

duties and responsibilities of contractors :::

a.commencement

a contractor behaves like this :
upon receiving the invitation to tender, a contractor should decide whether or not take up the project. If yes, the contractor need to complete it according to the tender documents.
(there are times where contractors should saught for the invitation for tenders !!!)
**most government's projects are open tender, contractors can involve themselves in tendering...to maximise the competition between contractors...to obtain the lowest possible price !!!

a contractor behaves like this :
a contractor should carry out full site investigation so that any unforeseen problem can be noted to ensure that they will not cause delays or extra costs once the construction process is underway.
(this is salient !!!! for example, if the bearing capity of the soil is too low and requires timbering when excavating the site, then because the contractor do not know about it and save the cost by eliminate the cost for timbering and misjudge the price for tender,and at the end, the contractor need to pay by himself for the cost )
**contractors should bear in mind.contractors are accused due to the full responsibilities in construction process.oh pity contractors!!!

a contractor behaves like this :
the contractor will then prepare then estimation based on information obtained from accurate studies of the bill of quantities, drawings, site investigation, suppliers' and subcontractors' quotation.
(nowadays, in order for contractors to obtain the required project, most of contractors hired a quantity surveyor to calculate the estimation cost of the tender, with the purpose to have a figure that is approximately or close to as suggested by the quantity surveyor to the client)
**there are also some cases where contractors try all out just to acquire the cost estimated by quantity surveyor to client!!!!!

a contractor behaves like this :
the contractor then return the estimation to the architect for his decision on acceptance or refusal according to other tender prices submitted.
(contractors' experience and ability are questioned and get consider ..)
**but most of times contractors summit the lowest possible price of the tender, better a bird in hand than no meat at all !!

a contractor behaves like this :
upon the architect and the contractor being satisfied with the price proposed by the contractor, he will discuss with all concerned parties.
(most of times they opted for the lowest tender's price..to save cost!!)
**the final decision is still in client's hand.the design team just advise and give opinion. so contractors, target the client !!

a contractor behaves like this :
when all amendments, disagreements and minor problems have been solved, sign the arrangments and condition of contract.
(communicate before it is too late !! after the contract is signed, nothing much the contractors can do but obey it .)
**the project is yours, contractor!!!!
