There are three essential requirements of any contract.
- Incentive: The prime aim is to provide an adequate incentive for efficient performance from the contractor. This must be reflected by an incentive for the client to provide appropriate information and support in a timely manner
- Flexibility: the prime aim is to provide the client with sufficient flexibility to introduce change which can be anticipated but not defined at the tender stage. An important requirement is that the contract should provide for systematic and equitable evaluation of such changes.
- Risk sharing: the prime aim is to allocate all risk between Client and Contractor. This must take into account the management and control of risk which materialize.
Types of Construction Contracts
There are various types of contract strategies in construction industry. Some of the main choices available are:
- Traditional Contracts
A consultant (or team of consultants) undertakes the process of feasibility, detailed
design, and contract preparation. A tender process follows and thereafter construction
installation and commissioning by the appointed contractor. The consultants who
developed and designed the project supervise these.
- Design and Build
A consultant undertakes the process of feasibility, establishing the client’s basic needs
and contract preparation. A tender process follows and thereafter the appointed
contractor undertakes detailed design, construction, installation and commissioning.
This type of contract is also known as turn key or prime contracts
- Management contracts
The client initially appoints consultants to undertake feasibility and costing and
perhaps outline design.A management contractor is appointed early in the project life and has considerable design input.
The management contractor’s responsibility is to prepare and appoints trade contracts or supply packages. Separate contracts are drawn up for independent parts of the construction project. A large amount of work is divided amongst several contractors.
- Build Own Operate Transfer (BOOT)
In its many forms a BOOT contract not only includes the initial design and
construction of the facility but a continuing maintenance and perhaps refurbishment
of over a number of years until final transfer to the client. Finance is often provided
by the contractor who recovers his cost through the life of the project. Other terms are
PFI, PPP etc
The concession agreement is the structured contract between the client and contractor.
It identifies and allocates risk.
Modes of Payments
The two main payment systems used in construction contracts are:
- Price Based: this system consists of lump sum and admeasurements. Prices or rates are submitted by the Contractor in his tender
- Cost Based: This payment system consists of cost-reimbursable and target cost. The actual costs are incurred by the contractor and reimbursed, together with a fee for overheads and profits.
- Price Based Payment System
A prime function of the contract is to allocate risk. The identification and
consideration of risk is a logical way to develop the organisational and contractual
policies for any project. Some of these uncertainties will remain whatever type of
contract is adopted and the contractor must then include a contingency sum for them
in his tender.
Different levels of risk contingencies can explain the wide range of bid prices
frequently received for admeasurements contracts. Another consequence of risk is that
fewer contractors are prepared to respond to or submit unqualified bids.
All parties to a project are at risk to some extent whatever the contract between them,
for instance that work may be frustrated by the forces beyond their control. If so, the
time lost and all or some of their consequent const may not be recoverable. The
choice of type of contract can motivate (or fail to motivate)
Now that you have decided to build a home, the next stage is to plan for construction. The aims of cost planning are to:
- Ensure that you are provided with value for money.
- Make you, as the home-builder, and designers aware of the cost consequences of their proposals.
- Provide advice to designers that enables them to arrive at practical and balanced designs within budget.
- Integrate costs with time and quality.
- To keep expenditure minimal
LOCATION, LOCATION, LOCATION….
In real estate as in business, the choice of location has a tremendous impact on cost and opportunities. It is therefore important to select a location which will favor you as home builder.
For example the cost per meter squared of building a home in Nairobi can be Kshs. 43,000 but constructing a similar unit in Nakuru can be KShs. 40,000. That Kshs. 3000 difference counts for a significant relief on your wallets.
Generally, building costs tend can to vary between locations due to one or more of the following factors:
- materials/products available or commonly used;
- ground conditions normally encountered;
- material/product prices due to distance from place of manufacture or distribution;
- distance from labor source;
- local regulations;
- labor productivity (e.g. due to adverse climatic conditions);
- builder’s risk and market conditions;
- labor rates – In Kenya,the rates for labor especially for individual home builders, is determined by personal negotiations with the the key contractor.
Another factor closely related to location is the characteristics of the land/plot
These are the geographical influences on land, including topography, climate, soil conditions, area, availability, cost and liability to earthquakes and flooding. In the past.
- Soil or geological conditions
These may have a bearing on the pattern of land use, the density and costs of development. Foundation type and complexity for any particular building are determined by the subsoil conditions. Unstable soil conditions can and the climatic conditions can also play their part in influencing development.
This can also influence building costs. Whilst elevation and views (particularly as development moves up a hill) are generally considered desirable, it comes at a premium. Generally, the cost of building on steep slopes is greater than that of building on level sites.
As home builder, it is important that you choose a suitable location before commencing planning any further.
