Departmental works and day work
If the work is executed directly by the department or owner, all the required men, materials, the department manages tools and equipment etc. In short, the department shall handle all the administration and management for the successful completion of works. This procedure of executing construction work is followed if:-
a)The work is of regular maintenance and repair type.
b)The work is of smaller size and the expenses are minimum.
c)Government rules and regulations permit.

Day work is used to denote a procedure of costing an item work on the basis of actual labourers and materials required. Certain item work on the basis of actual labourers and materials required. Certain item of work that cannot be measured as a design in the plasterwork, the front architectural finish of a building, work underwater etc. are valued and paid by “day work”. The “day work” prices usually include material, labour, transport, contractors profit and overhead charges, tools and plants etc.
Tender and tender notices
Usually, the construction of large and complicated projects, where the cost of construction will be high is not subjected to be executed by the department, directly. Government’s rule and regulation will limit the execution of such type of work by department. Execution of such type of work by contracting and for this tenders are called.
Tender is a written presented before the owner or department in order to perform the specified works within a specified time under the agreed obligations.
Tender notice is a means of expression, through which contractors may know where they have to bid a tender. Tender notice shall be published in such a way that all the concerning parties get the information in time. Thus, such tender notice shall be published in widely read newspapers or through other media from where the notification reaches the concerned parties. A tender notice shall contain the following information:-
a)Date, time and place of tender
b)Name of the authorities inviting tender
c)Nature of work and its location
d)Time of completion
e)Validity of tender
f)Amount of earnest and security money
g)Cost of the complete set of tender forms and conditions.
h)Estimated cost etc
Earnest money and security money
Earnest money provides a guarantee of the party’s willingness to carrying out the work if he is awarded. This money is deposited while bidding a tender. 2.5% of the estimated amount or bidding amount (normally bidding amount) is demanded as earnest money. The earnest money deposited will be returned to the unsuccessful bidders. In the case of the successful bidder, the earnest 2.5% is turned to the security deposit with the addition of other 2.5%.
On the acceptance of the tender, the contractor should deposit 5% of the tendered amount as security money with the department which is inclusive of the earnest money already deposited. It is also known as a security deposit. The amount is kept as a check so that the contractor fulfils all the terms and conditions of the contract and carries out the work satisfactorily according to the maintain progress and specifications and completes the work in time.
Preparation before inviting tender and agreement
In order to execute construction work through contracting, we need to invite tenders from the eligible parties. Before inviting tender following steps are to be followed:-
2)Detail design and const estimation
3)Approval of cost estimation
The agreement is a consensus between the successful bidder and the owner and it has a legal meaning. Agreement between the two parties should have the same spirit and understood in the same way.
Any supervisor or overseer deputed to the site should thoroughly supervise the work of a contractor. The best interest of the contractor will be always to keep the cost of construction as low as possible. A contractor guided by his best interest may try to cheat the owner by doing inferior work i.e. using inferior materials not following the instructions, without following time sequence etc. Thus, all the works shall be done in the presence of overseer, only in the confidence of an overseer further works shall be done.
