Preliminaries (or ‘prelims’) provide a description of a project that allows the builder to assess the work required to formulate a scope and or a cost analysis. Depending on what stage you are at, some of the preliminary work undertaken by One8 Projects includes:
A client in the very early stage of land purchasing phase, or have yet to engage a designer/architect, may require us to perform all tasks in the list. If the client has already got these documents in order, One8 Projects may be required to review the documents and produce a tendering quote.
For a custom build project over $800,000, it is normal practice to engage the services of a Quantity Survey (QS) and work of Bill of Quantities (BoQ) early in the design process. The main purpose of a BoQ is to itemise and define a project so that all tenderers are preparing their price and submission on the same information.
It is not uncommon to find that the quotes from builders differ to the BoQ report, this can be due to:
Each builder has a different assessment to the project risk and applies a different methodology to run the project. One8 Projects ensures all projects we delivered are tested through our rigorous quality assurance program before it is handed over. We have developed systems and procedures to allow a consistent level quality.
To make the quote/contract as accurate as possible, you need to define what exactly is going to be included down to details such as what light bulb you are going to use. Sometimes, that is not possible at the time of quoting or contracting. There are two common terms used to allow for such variables. Prime Cost Item (PC): Is an allowance made in a tender or contract for the supply and delivery only of an item or items of material (e.g. taps, baths, light fittings etc.) that have not been selected at the time of tender or before the contract is signed or for which the Contractor was not able to provide a fixed price on entering the contract. The Proprietor/Owner would normally make the final selection of the item, which is subject to a PC allowance.
Provisional Sum (PS): Is an allowance made in a tender or contract for particular work which could not be finalised before tendering or signing a contract and which includes the total cost of the supply and installation (e.g. joinery, landscaping, air conditioning, rock removal). Where Prime Cost Items (PC’s) and Provisional Sum (PS) allowances have to be shown in a tender or contract document, the amount shown should be inclusive of GST.
A survey, which is required for the purpose of identifying existing buildings and improvements on a parcel of land, is referred to as an Identification Survey or just Ident. It may only be undertaken by a Registered Surveyor. It is always recommended to engage a Surveyor for an Ident survey when you are purchasing a property. Your solicitor will normally obtain an Ident report as a matter of course. He does so to protect you against any problems that can only be detected by a Surveyor. The Vendor Disclosure Legislation requires obligatory warranties and other statutory information from a vendor of the property. The Ident report can supply other required information and speed up the sale.
Through your Ident Survey you can be sure that you are not buying any problems that may make the property difficult to sell in the future or create anxiety with neighbours or public authorities before you even move in. More importantly, you are sure that you are buying the property that you have been shown and whether or not the property has any defects that may devalue it.
A Surveyor measures the site involved to determine the location of buildings on or adjacent to the land and any fences present. He will check for the existence of Easements (for drainage, etc.), Covenants and Restrictions on land use, and whether or not the subject land complies with the terms of these conditions. The Surveyor pays special attention to any encroachments by or upon the land or upon any Easements. In the instance of a residence the Surveyor will report on the distances of the walls or eaves and gutters from the side boundary of the land.
Detail surveys are a basic prerequisite for building and land development. In most cases, the purpose of detail surveys is to indicate features on, and adjacent to, a property. There are a number of site features and levels required by architects and planners. A topographic survey is a vital component of a successful development application for any development of your land.
Features of general detail surveys include:
o Levels & contours related to Australian Height Datum (AHD) o Tie into cadastral reference marks & plot approx boundary on plan
o Field survey of site detail & features
o Field location of visible services
o Spot levels & contours over site
o Detail of significant trees on site over 0.2 diameter trunk
o Note of retaining walls, changes of grade etc onto adjoining sites
o Location of existing and adjoining houses/structures and floor and apex levels
o Pickup of road & kerb details at site to crown
o Place site level datum
o Dial before you dig searches
o Projects involving excavation will require an assessment to find out what services are underground around your property. Common searches include:
One8 Projects can advise if there are problems connecting your house to the mains. Common problems can be:
Part of the preliminary searches will involve extracting information from council regarding your property. Most of these searches are done through publicly available data. One8 Projects can help you make sense of the search result. We pay attention to these common constraints:
The result will determine if we need to call on other specialist consultants such as a town planner, or hydraulic engineers.
