Tips For Home Owners

 

How Builder's Rip Off Their Clients
There are numerous ways builder's can rip off their clients. Some things owners should be aware of are listed below ;

  • PC ALLOWANCES. “PC” Allowance is “PRIME COST”. This is an allowance made by the builder in his construction tender as he is not certain of the selection of certain building materials and therefore does not know the exact cost for supply only of this item.  The builder has already allowed labour to install the item as a fixed price included in the tender price. Typically this an allowance includes items such as kitchen cooking appliances, bathroom wall & floor tiles, bathroom fittings).
  • PS ALLOWANCES. PS” Allowance is “PROVISIONAL SUM”. This is an allowance made by the builder in his construction tender as he is not certain of the amount of labour & materials of certain construction tasks and therefore does not know the exact cost for supply of materials & labour to complete this task. Typically this an allowance includes items such as siteworks, demolition, concrete peering, kitchen cupboard joinery, painting). Sometimes this item is impossible to calculate the exact cost at the tender stage (e.g. concrete piering).
  • HOW THEY WORK. The way PC & PS allowances work in a contract is that the owner is charged the difference between the allowance and the actual final cost. If the allowance is not spent then the owner receives a credit for the difference. If the actual cost exceeds the allowance then the owner is charged the difference between the allowance and the actual cost, plus an agreed percentage for builders margin to cover his overheads & profit
  • DELETING AN ALLOWANCE. The owner also has the option to delete the allowance totally from the contract and receive a credit for the full amount. However the owner then takes on the full responsibility for the supply of the item or for the tasks to be completed. This means the owner is responsible for the insurance of supply of any item (e.g. theft, damage etc) and quality o the installation of the item and any delay costs
  • MINIMISE PC & PS ALLOWANCES. The best tenders have the least amount of PC allowances. Its best to make as many selections as possible before the contract is signed and construction work commences. This can include selecting all tiles, bathroom fittings, kitchen cooking appliances. Get quotes for kitchen joinery & painting if possible. This will minimise delays and possible budget overruns.
  • UNREALISTIC PC ALLOWANCES. If a PC or PS must be included in the contract it should be a realistic figure as close as possible to the final cost. Better to over estimate the allowance than under estimate it. If
  • UNQUOTED VARIATIONS. Most variations can be quoted for before any work is completed. However if in the rare case it cannot be quoted (eg replacement of termite damaged timber) the variation needs to be proved by supplying a copy of any material purchase invoices to the owner plus a charge for labour at an agreed rate and a builder percentage for overheads and profit
  • GST. This can be double charged if not correctly listed in the tender. Its would be very clearly noted whether the allowance includes or excludes GST. Owners should be given a copy of all invoices for material supply and/or sub-contractor quotes and ensure any invoices clearly state whether GST is included or not. The builder can easily double charge for GST on the sub-contractors invoice and then again on his invoice to the owner if this is not clearly checked.
  • LABOUR RATES. These should be fair and reasonable. It is common for many builders to include excessively hire labour rates for any extra work that may be required. All labour rates would be clearly stated in the building contract so that the owner knows exactly what labour rates will be charged for.
  • EXLCUSIONS. Builders can make more money by excluding an item rather than completing a variation by not passing on the full amount of any excluded item in the contract to the owner when an item is deleted. If the owner is thinking of excluding an item during construction they should ask the builder to include what the credit amount would be in the contract prior to contract signing.
  • TENDER VALIDITY. All good builders will state in their tender how long their tender is valid for before they can revise it for industry rise and fall. This is usually between 30 and 90 days. Owners should not sign a contract until plans are passed by council and the builder is ready to start on-site immediately. Otherwise they run the risk of being charged for excessive price rises imposed by the builder. The owner can also ask for evidence from builder's suppliers proving they have actually incurred the price rise they are claiming for.
  • WRITTEN INCLUSIONS. Owners should insist that all of there requirements are included in the tender in writing. If it is not written in the tender the owner will have no legal right to claim for the inclusion. The tender should be attached to the contract and every page signed by both parties with a copy for each party supplied. The most important element will be communication & trust between both parties. The above are only a few of the ways builders can rip off their clients. Owners should check the builders experience, check references and evaluate the builder not only on price but also on professionalism

Progress Claims - When you need to pay the builder
There are numerous ways that progress claims can be made. They can be made every 2 weeks for up to 95% of the value of the work however this method gives no incentive for the builder to perform and complete the work ASAP.

We prefer for progress claims to be made at set intervals when a construction stage is met.

Each schedule of progress claims is customized to the job but a common break-up of claims is as follows;

DEPOSIT Max 10% of the contract price

  1. CONCRETE POUR
  2. DELIVERY OF FRAMES & TRUSSES
  3. DELIVERY OF BRICKWORK
  4. FASCIA & GUTTER INSTALLED
  5. ROOF TILES / IRON DELIVERED
  6. PLUMBING & ELECTRICAL ROUGH-IN COMPLETED
  7. PLASTERBOARD / INTERNAL LINING DLEIVERED
  8. LOCK-UP (HOUSE IS SECURE)
  9. FIXOUT DELIVERED - DOORS & ARCHITRAVES
  10. CERAMIC TILING COMPLETED
  11. PAINTING COMPLETED
  12. PRACTICAL COMPLETION

Final payment is required at "Practical Completion". This is the stage when either the owner moves into the house / addition or when the house is complete, except for maintenance items.

Owners have 13 weeks after they move in to supply a maintenance list of minor items to be completed or rectified. O'Mara does not usually enforce this 13 week period and we often return to inspection any owner concerns may months after the work has been completed.

Each project O'Mara completes is totally different. A schedule of progress claims is prepared and included in every building contract to suit the project. Adjustments can be made to suit both parties when required.

INSURANCE - IS EVERYTHING COVERED

HOME WARRANTY INSURANCE (now called HOME BUILDING COMPENSATION FUND)
This insurance policy covers the owner against fault by the builder. If the builder dies, goes broke, retires or will not rectify faulty work then the insurance company will pay out the owner and pursue the builder. The builder must obtain the insurance policy directly. If the builder cannot obtain his own home owners warranty insurance policy it is probably because he is unlicensed, has had previous claims against him or has a limit on the amount of insurance that he can obtain. The better the builder is the more insurance he is able to obtain and the lower his premiums will be. Some builders are also limited to the type of work they can perform to what maximum value.

If a builder asks you to obtain the home owners warranty insurance policy directly beware. This puts all of the responsibilities on the owner and NOT the builder. The owner losses all rights to claim against the builder. We strongly recommend against this. The builder should always obtain the policy.

O'Mara has NEVER had a claim by any previous client against home owners' warranty insurance. We are rated by our insurer as a CLASS 1 builder. The highest rating available. We can obtain insurance usually within 48 hours.

CONTRACT WORKS INSURANCE
This covers all new materials delivered to site and all new work is fully insured against theft, vandalism, fire and any other damage.
O'Mara is fully covered for this insurance at all times.

WORKERS COMPENSATION INSURANCE & SICKNESS / ACCIDENT INSURANCE
All people working on site need to have insurance to cover any accidents and injury on site
Companies need to have workers compensation insurance, sole traders only need to have sickness & accident insurance.
O'Mara is fully covered for this insurance at all times.

PUBLIC LIABILITY INSURANCE
This covers all anyone who enters the site and hurts themselves on site. It does not matter if they were allowed to enter the site or if they were trespassing. They still need to be covered. Councils usually require cover for up to $10,000,000.
O'Mara is fully covered for this insurance at all times.

HOME CONTENTS INSURANCE For HOME ADDITIONS & RENOVATIONS
O'Mara cannot cover your house "contents" with our standard construction insurance. You will need to check with your insurance company that your house contents is covered while renovating against theft or damage (eg water damage), some companies will cover you, others will not. If your current insurance company will not cover your contents while renovating you may need to take out a separate policy to cover your contents during construction. O'Mara cannot cover your contents as they are not our property.

EXISTING HOUSE "STRUCTURE" INSURANCE
You should also check to see if your current house insurance will cover your existing residence "STRUCTURE" during construction. This is to cover your existing home against damage during construction not caused by the builder. (Eg water damage, fire, electrical shorts, etc). If the builder caused the damage the builder is always liable for any damage. However if the damage is caused by a fault in the existing home and has nothing to do with the new work being completed then insurance is required to cover the existing house structure. Many insurance companies will not your existing house while building work is being completed. We can take out a special insurance cover for your existing residence  "STRUCTURE" if your current insurance company will not. The cost of this policy can be obtained upon request

SITE CHECKLIST

When preparing a tender it is very important that the builder complete a very comprehensive checklist of the existing site and home condition. With every project we complete a comprehensive site inspection and record the condition of all items for the preparation of our construction tender. This makes our tender more accurate and reducing the amount of possible variations during construction. A sample is shown below;
