12.  Lump sum Contract
• A lump sum contract is normally used in the construction industry to reduce design and contract
administration costs. It is called a Lump Sum because the contractor is required to submit a total and
global price instead of bidding on individual items. A lump sum contract is the most recognized
agreement form on simple and small projects, for example, projects with a well-defined scope or
construction projects where the risk of different site conditions is minimal.
 Design and build contract
• Design-build is a method of project delivery in which one entity - the design-build team - works
under a single contract with the project owner to provide design and construction services. One
entity, one contract, one unified flow of work from initial concept through completion. Design-build
is also known as design/construct and single-source responsibility.
 Item rate contract
• These contracts are also known as unit-price contracts or schedule contracts. For item rate contracts,
contractors are required to quote rates for individual items of work on the basis of a schedule of
quantities furnished by the customer. The contractor bears almost no risk in these contracts, except
escalation in the rates of items quoted by the contractor, as it is paid according to the actual amount
of work on the basis of the per-unit price quoted.

20. Bar-Bending Schedule
Bar-bending-schedule is the schedule of reinforcement bars prepared in advance before
cutting and bending of rebars. This schedule contains all details of size, shape and
dimension of rebars to be cut.

21. • Lap length
• Lap length is the length overlap of bars tied to extend the
reinforcement length.. Lap length about 50 times the diameter of the
bar is considered safe. Laps of neighboring bar lengths should be
staggered and should not be provided at one level/line. At one cross
section, a maximum of 50% bars should be lapped. In case, required
lap length is not available at junction because of space and other
constraints, bars can be joined with couplers or welded .
• Anchorage Length
• This is the additional length of steel of one structure required to be
inserted in other at the junction. For example, main bars of beam in
column at beam column junction, column bars in footing etc.

22. Cover blocks:-
*Cover blocks are placed to prevent the steel rods from touching
the shuttering plates and there by providing a minimum cover and
fix the reinforcements as per the design drawings. Sometimes it is
commonly seen that the cover gets misplaced during the
concreting activity. To prevent this, tying of cover with steel bars
using thin steel wires called binding wires is recommended.
Covers should be made of cement sand mortar (1:3). Ideally,
cover should have strength similar to the surrounding concrete,
with the least perimeter so that chances of water to penetrate
through periphery will be minimized. Provision of minimum
covers as per the Indian standards for durability of the whole
structure should be ensured.
*However, cover indicates thickness of the cover block.
Normally, cubical cover blocks are used. As a thumb rule,
minimum cover of 2” in footings, 1.5” in columns and 1” for
other structures may be ensured.
