TERMS AND CONDITIONS
1. The “Estimations” are based on standard construction methods and average output rates of construction works in Ghana. The CONSTANTS in the Estimations were computed from input and output rates of previous practical works, materials utilization specifications, National Labour and Plant output rates and National All-In Labour and All-In Plant hiring rates obtained from various, recognized and well established construction institutions in Ghana with the practical experience of the Author.
2. The “Unit Rates” in addition with your desired percentages for Profits and Overheads determines the responsiveness of your Tender Rates. Depending on the choices of materials, labour, and plant used, some of the Rates may seem over or under estimated which still offer you the opportunity to adjust accordingly at your own discretion when adding your Profits and Overheads percentages. The insertion of percentages for Profits and Overheads determines the final (Tender) rates for bill items. This eventually determines the cost of construction works being priced with those rates.
3. The “Cost Components” only depicts to you the cost breakdown of all the inputs required to execute units of various quantities. With ease, it helps you to analyze the unit cost of Materials, Labour (Labour Rates), and Plant (Plant Rates) for quantities of the various bill items.
4. “The “”Extractions”” upon item “”1″” above, only extracts those components that build up quantities into their commercial units
“(e.g. Extracting the bags of cement, trips of sand and aggregates, labour and plant days/charges required for a specific quantity of concrete, 1:3:6/18mm aggregates). This can be used to prepare material, Labour and plant schedules.
5. This Estimator is only to gives you an instant rough idea of the cost of your project. This is because it is designed not for your project only but to suit every other kind of simple building. The Estimator is suitable for all simple buildings only but not storey buildings and / or skeletal system of buildings.
The Estimator largely depends on:
a. the required information you will enter. Make sure the information are as exactly as those in your drawings as possible. Avoid giving allowances in dimensions. The Estimator only needs each of the information above described as required, to establish their relationships with all other items in order to quantify and estimate for them. Do not fill in any information that is not part of your plans. Any entered information that is not intended for will automatically generate and estimate for other related items. For example: just keying-in ‘1’ for number of WCs means the system will automatically estimate for all other associate plumbing works (like: PVCs pipes, inspection chamber(s), septic tank/manhole etc.) that have to be executed before the WC can be installed. This can raise the estimated cost to unimaginable value. That is to say, leave number of WCs at zero (0) if it’s not part of your design or not required.
b. the use of the software’s “unit rates” sheet which also depend on the updates of the prices of Materials, All-In Labour rates and the All-In Plant Rates. It is the user’s responsibility to ensure that prices and rates are up-to-date.
c. the use of multiple pricing: That is, but not all, some items of the same characters but different in shapes are measured together and the software uses the same unit rate for their pricing.
d. Standardization: The software will or does not recognize and/or consider shortcut ways or any form of saving or reducing cost by reducing quality except in concrete mix ratio options. That is, you may only reduce costs of concrete works by manipulating their mix ratios. Any other item will be considered to meet standard quality irrespective of how cheaper you want your project to cost.
e. The estimation Form for this version is not applicable to storey buildings and/or skeletal system of buildings. Check out for the next version for such feature.
6. The “Data Base” is where you the users feed in prices of materials, labour charges and plant hiring rates from the market into the software. The “Data Base” sheet is very paramount to the software just as the fuel tank of any vehicle and the data you fill in is as important as the fuel. The functionality and efficiency of the software in giving responsive rates, estimates are wholly dependents of the entered market data obtained from the locations where you operate or intent to tender for projects. Feeding in data information that are inaccurate or not up-to-date, would lead to larger margin of error of whatever this software does.
7. The “Payment Certificates” offer you the opportunity to prepare payment certificates with ease within the shortest possible time and without errors, provided your input information are correct and that’s the accuracy of the certificates simply depends on your inputs
8. All the above items suggest that, the “margin of error” of BaniEstimations outputs cannot be assured. That is to say, the “margin of error” rather depends on your input information MOST.
10. This means, BaniEstimations shall not be liable for any damages cost to you or a third party as a result of relying upon it’sinformation for contracts, business transactions or any kind. Continuing to rely upon it’s information means you’ve read and agreed to our Terms & Conditions .
