This website is designed to assist you to manage the building process by yourself with advice, hints and tips every step of the way
If you have decided to do it yourself, there are two options:
1. Owner Builder.
2. Appointing a Building Contractor
Once you have made your decision, you will need a tender document, a contract document and related documentation to protect you and minimize your risks during the contract period.
There are a number of different types of contract documents available. (Refer to the section on Contract Documents)
One of the most important fundamentals of a building contract, is the basis on which the contractor tenders for the building work. It is important for the different tenderers to have sufficient information when tendering. Whenever there is uncertainty in the documentation, the contractor add to the cost in order to cover himself - who can blame him? It is also important to ensure that the tenderers have a uniform basis for competitive tendering, in other words to compare apples with apples when judging the tenders.
Contract without quantities with schedule of rates: The contractor tenders for the work on a lump sum basis using only the building plans to determine the tender amount. It comprises of the building work which includes the setting out, the foundations, the brickwork, plasterwork etc. as well as the various sub-contractors which goes out on separate tenders as the work progresses like for instance the roof structure, aluminium windows, kitchen fittings, carpets etc. It is advisable that the contractor provides a schedule of rates for the building items. It makes it easier and forms the basis to calculate the cost of any changes to the building work (which there always are!). As part of the tender document, there is a list of so-called "provisional amounts" for the various sub-contracts included. For instance a calculated provisional amount for carpeting is included in the tender amount, which will be finalized when quotes have been received for the carpeting. This is to ensure that the most competitive prices are paid for as many items in your house as possible.
When making changes on site during the construction period, insist on a quote for the additional work from the contractor before instructing him to go ahead. No matter how good your relationship with the builder is, this always leads to arguments at the end. It also avoids overspending on the budget. It is easier to control the costs when a schedule of rates is available.
An example of a standard Tender Document which includes a list of possible provisional amount items, is included in the documentation you receive when buying a house plan from inhouseplans.com.
Contract with quantities: A contract with quantities means that a quantity surveyor or one of various companies specializing in providing this service, is appointed to calculate and prepare the bills of quantities, listing all the work, trade by trade and in accordance with a nationally recognized system of measurement. This is a very accurate way of determining the building cost and a sound basis for the calculation of monthly payment certificates, as well as for cost analysis and cost control. There are various companies specializing in providing this service at a very competitive price. (Refer to the section - Business Directory, Bills of Quantities). Chances are good that the additional cost of this documentation will be off-set by good cost control.
Cost-Plus contract: This contract consists of an agreement between yourself and the contractor whereby the final building cost is determined by the proven costs for material and labour with a fixed amount or a percentage (normally between 8%-15%) paid to the contractor for overheads and profit. It is important to determine a ceiling amount on this type of contract. Due to the fact that amongst others, cost control on this method is very difficult and material wastage is for your account, this type of contract is not recommended.
General: It is important to communicate regularly with your building contractor and build a good relationship of trust. It is important to hold formal site meetings and record items discussed, instructions to the contractor and decisions made in a set of minutes. For this a pro forma agenda for site meetings is available when buying an architect designed house plan from inhouseplans.com. Do not hesitate to put pressure on the contractor if he falls behind on his program, or if the quality of work is not acceptable.
It is important to hold some sort of guarantee from the contractor to ensure that the contractor will complete the work, either in the form of a so-called construction guarantee, or a retention amount which is held back on the progress payments. This normally amounts to a total of 5% of the tender amount. One word of advice - do not spend this money on the final finishes, and go looking for all sorts of excuses not to pay the contractor even if he has performed reasonably well. The purpose of the guarantee or retention is to cover the owner in case the contractor fails to complete the work satisfactorily and another contractor needs to be appointed to complete the work. Remember the contractor needs to be given reasonable time to perform and the contract makes provision for the process to manage matters in this event
If your tender process is handled properly and correctly, it will be a good start for a successful building project. With your sets of building plans when buying an architect designed house plan from inhouseplans.com, you will receive a pro forma tender document with a list of possible provisional amounts as well as a tender form. The contractor must complete the tender form and submit it to you on the stipulated time.
Where do I find a good building contractor to tender? Ask around. Word of mouth is always the best reference. Drive around in your area of town, check out the building work and find out the details of the contractors. Lastly refer to the section on Building Contractors (Regional) in the inhouseplans.com' Business Directory section. We cannot guarantee the quality of the contractors in our directory, but we have a system in place whereby we omit the name of a contractor from the list when we receive a legitimate complaint from our inhouseplans.com clients. Please assist us, by letting us know of a bad experience with a contractor.
Useful hints on the tender process
There are a number of different types of contract documents available. The document recommended by inhouseplans.com, is the Joint Building Contracts Committee (JBCC) 2000 Minor Works form of contract. This contract document can be ordered with the set of building plans on inhouseplans.com.
This document is supported, amongst others by the following constituent bodies:
Also published by the Association of South African Quantity Surveyors is the Housing and Minor Works Contract intended for small building work.
Progress payments are a very important part of managing the building process. Although it is advisable to appoint a quantity surveyor to assist you especially on contract values exceeding R1,000,000, it is possible to do this yourself with the help of inhouseplans. If you finance your building work with a home loan, the bank will send their valuator to the site and determine the amount of progress payments to the contractor. That is a great help, as the banks tend to be very conservative. However, they expect you to spend your own contribution to the total building cost first. The golden rule here is to never overpay your contractor, as that puts you at risk. The other side of the coin is that it is important not to underpay your contractor either. Contractors specializing in house building projects are very often small companies. They do not have a big capital base and rely on the cash flow provided by the progress payments to keep going. By underpaying him could slow down progress on site and start a chain reaction which causes all sorts of other delays and potential problems. On the other hand, you don't pay for work that is not done to specification.
To assist you in this crucial part of the building process, a pro forma schedule is included in the documentation you receive when buying a set of building plans of one of our architect designed houses from inhouseplans.com. This schedule provides a list of all the building trades and an easy- to-use formula to calculate the value of work done on site. If you order the List of Materials and Quantities, with any set of building plans, you will have a schedule of building items with unit prices to further assist you in the calculation of progress payments, as well as the cost of any revisions.
What is building a house without a little dispute with the builder? The secret is to accept that there will be differences and to resolve it as soon as possible. It is also here that building a good relationship with your contractor will be to your advantage. Remember, in settling a dispute it is almost inevitable that both parties need to make concessions. If you cannot reach an agreement on the dispute, most contracts make provision for either mediation or arbitration or both. In both instances, a third and independent person is involved to act as a broker to assist in settling the dispute. Mediation is quicker and an informal process while the ruling of the mediator is not binding on the parties. Arbitration is governed by the Arbitration Act, with the arbitrator, a qualified person, recommended by the Association of Arbitrators. Due to the fact that attorneys and advocates are normally not involved, the process is significantly less expensive than going to the Court, but equally binding
The best advice is to settle your disputes before it becomes major issues and thereby jeopardize achieving your goal to build your dream house
