Σύνοψη

There are two types of Bills of Quantities:
1. Trade bills.
2. Elemental bills
1. Trade bills
A typical division of a trade bill for quantities would be:
1. Preliminaries
2. Excavation and earthwork
3, Concrete work
4. Brickwork and blockwork
S. Roofing
6. Woodwork
7. Plumping installations
8. Floor, wall and ceiling finishings
9. Glazing
10. Painting and decorating
II. Drainage
12. Prime cost and provisional sums.
The advantage of 1his method is that the pricing of the Bills of
Quantities at tendering stage can be done very easily.
2. ELEMENTAL BILLS
Elemental bills are devided in sections in accordance with the
various main sections of the building e.g.
Internal waIls
External walls
Floors
etc.
The disadvantages of the elemental bills is that the pricing of the
Bills at tendering stage is complicated as the same item of work
may appear in different sections of the bills. Thus there is
mmecessary repetition of the same prices in different sections of the
Bills, whilst the full extend of each item of work, which affects the
prices considerably, can only be known by adding up the quantities
for this item that appear in different sections of the Bills.
The advantage of this method is that the location of most items
will be apparent by their position of the Bills of Quantities. This
facilitates the administration of the contract on site (e.g. ordering
materials, deciding the required nwnber of operatives on site,
preparing interim valuations etc.).
Trade Bills are generally more widely used than elemental bills.
