QUANTITY SURVEYING

Quantity Surveying

refers to the estimation of materials as well as the final cost of estimation

Cost Estimating

one of the most important steps in project management. It establishes the base line of the predicted project cost at different stages of development of the project

Estimate

should be realistic assessment and should be made on actual conditions of the market.

Estimating

it is the process of looking into the future and trying to predict project costs and resource requirements. To minimize errors, a consistent procedure or set of steps for preparing an estimate is needed to minimize errors and achieve reliable results

Main Purpose of Estimating

to know in advance the expected cost in varying degree of accuracy, at different phases of the project.

Owner’s Purpose of Estimating

Making investment decision in the conceptual stage.

Negotiate and finalize the contract at the implementation phase.

To implement cost control measures

Contractor’s Purpose of Estimating

Determine project cost and profit.

To Implement cost control measure.

To develop data base for that can be used for future project.

Money

You calculate your cost, apply your mark up, and present the total to your customer.

Accuracy

Your business will only prosper if your estimating is accurate, so you make a profit without giving your customers any unpleasant surprises between a preconstruction estimate and the final amount to be paid

Speed

Customers want their estimates rapidly. For commercial and industrial projects, customers are unlikely to wait weeks for your cost estimate.

Conceptual Estimate

Prior to the commencement of design

A representative unit is multiplied by a price per unit to obtain a gross estimate (± 10% accuracy) of the facility cost

Preliminary Estimate

40% completion of the total design

By the architect or engineer to reflect expected costs based on more definitive data

Engineer Estimate

Detail design is accomplished

Total job cost minus mark-up

Should achieve approximately ±3% accuracy

Bid (Contractor) Estimate

Bidding phase

On the basis of the bidding documents

Include a mark-up for profit

Direct Cost

The costs of materials, labor, equipment, etc. or expenses for the cost objects.

Indirect Cost

Are typically allocated to a cost object on some basis. All cost which are required for the completion of the project.

Pre-bid meetings

are held during the bid/proposal preparation period. The purpose of this is to clarify any concerns bidders may have with the solicitation documents.

Site Visit Inspection

inspection of existing site conditions that should be incorporated in the preparation of the bid.

Bid Plans

technical drawings that show what is to be built for the purpose of bidding.

Material Take-off (MTO)

a term used in engineering and construction, and refers to a list of materials with quantities and types that are required to build a designed structure or item. This list is generated by analysis of a blueprint or other design document.

Geotechnical Investigation Reports

include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved

Price Quotations

a quote is the last price at which a security or commodity traded, meaning the most recent price on which a buyer and seller agreed and at which some amount of the asset was transacted

Preliminary Costs

expenses that will be incurred during construction, which are directly related to the running of the project and have not been included in the materials, labor or overheads.

Temporary Facilities

are offices and accommodation buildings including warehouse, utilities including water and electricity and infrastructures including access way, and security systems to be used for the construction activities.

Testing and Commissioning

to be carried out on installations to ensure that materials are safe and meet the design requirements.

means the general direction, coordination and oversight of on-site work processes

Bill of Quantities

a document used in tendering in the construction industry / supplies in which materials, parts, and labor (and their costs) are itemized. It also details the terms and conditions of the construction or repair contract and itemizes all work to enable a contractor to price the work for which he or she is bidding.
