The use of measurement software in building industry has focused on dimension and BQ since these two have been the predominant core activities of work. However, even as we are aware today, the utilization of computers can be employed to numerous different situations. This section will review the application form and top features of measurement software in local development companies. The common program functions of dimension software such as way of measuring, cost estimation, tender document planning, BQ preparation and the like will briefly defined in the first sub-chapter.
In addition, case studies of way of measuring software available in market whether local or foreign will be conducted in this chapter. This chapter will provide the key features or modules of the Microsoft Office Excel 2007, CATO Collection, BinaLink, Buildsoft, WinQS, PriMus-DCF and PriMus REVOLUTION in additional information. The positive or negative effects of dimension software on local engineering industry will be discussed and completed by few review analyses additionally. A listing of this section will be offered in the last section.
Questionnaire will be drafted predicated on this section to meet up with the last two aims of the research which will be the extent of measurement software application and the resulted effects from it in local construction companies.
Measurement software were created and developed to assists the tasks and obligations of QS job in a structure companies with minimal time and higher precision. Software functions of way of measuring software enable to execute the next:
Measurement is the primary activity that any quantity surveyor partcipates in during the stage of tender planning. Curren (1987) advocates that computer can evaluate quantities automatically and it is more accurate compared to measurement done physically (cited by Lim and Ong, 2008). This goes to show the use of personal computers is vital to the number surveyor as it helps in reducing the time needed for taking-off quantities.
Ahuja and Campbell (1988) described that cost estimation is prediction of possible cost incurred for a proposed engineering project. It really is a complex process and has been referred to as both an art and also knowledge. Estimating is usually carried out by variety surveyor or estimator with respect to contractor with the try to forecast the sensitive total to be included in the BQ before submitting the sensitive. The purpose of the cost estimation is to obtain the expected cost of a project in varying degrees of accuracy at different phases of project. Cost estimating software will enhance the accuracy while estimating the building cost and verify the implication of preliminary cost design.
Computer systems are used to facilitate this process by automatically minimizing two times keying work and thus saving plenty of time. In term of BQ creation, Microsoft Excel is trusted for doing taking off and preparation of BQ. Traditional spreadsheet dimension sheet have the ability to reduce the burden of timesing and squaring as well as checking of the two steps (Hamid and Chong, n. d. ). BQ creation involves an extended and tedious process. Nigel (1978) has posted out eight major steps in creating a BQ as below:
- Measurement of Quantities
- Timesing and Squaring
- Checking of Timesing and Squaring
- Checking of Abstracting
- Preparation and Checking of Draft BQ
- Preparation of BQ and Checking
- Final BQ
The phase of planning of the sensitive documents is really important, as it can determine the terms of the sensitive procedure as well as the terms for execution of the contract. Kovari (n. d. ) observed that seven documents will be provided in sensitive documents prep and the format of it could be saved in to the storage area of the computer systems as shown below:
- Advertisement for Bids (Notice to Contractors or Invitation to Bet)
- Draft Contract including type of agreement, general procedures or basic conditions and special provisions or special procedures.
- Statements of Work, Services and Tech Specifications
- Schedule of Execution
- Bidding Schedule
- Approved Drawings
Cost control starts at inception, when guide prices or indicative costs will be required through the stage when an early price estimation is prepared and the sensitive process carried out by the companies through the ultimate completion and agreements of the final account for the job. The architect or engineer would want to consider alternative solutions that meet up with the client's overall seeks and objectives during the various stages of design. The number surveyor will offer cost advice for the comparative design solutions of the choice materials to be used and also advice on the cost implications of the look morphology and procurement. Cost control does not stop at sensitive stage but carries on up to the contract of the ultimate account and the issue of the final license for the works. Hence, cashflow estimating software permits volume surveyor record and calculates the particular date driven effectively and faster. Additionally it is providing an improved monitoring on the building process (Ashworth and Hogg, eds, 2007).
In practice, the agreement normally is to be paid by employed a sum on bill as the building work proceeds. Before the Architect issuing a license, quantity surveyor must make an interim valuation (Lian, 2009). Interim valuation can be executed utilizing the BQ programme as databases usually. The main items to be looked at when valuing the words area as following:
- Main Contractor's Works
- Unfixed Materials and Goods
- Statutory Fees and Charges
- Nominated Sub-Contractors Works
- Nominated Suppliers Goods
- Fluctuation in Costs of Labour, Materials
According to Ashworth and Hogg (eds, 2007), nearly all construction projects lead to a final cost that is different to that decided by your client and service provider at commencement of the engineering works. The computation and agreement of the final development cost, the ultimate bill is usually of the most importance to both the employer and contractor. Therefore, get-togethers to the contract need to ensure that the ultimate account incorporates a fair valuation of the works carried out. Within lump total contract arrangements the purchase price agreed by the client at commencement will normally require modification for several issues including modifications, provisional measurements, provisional amounts, fluctuations, and promises. Thus, quantity application software will sort, store and analyse the capability and score the goal of time saving.
Anything and everything can be computerised nowadays. It is unavoidable that the sophisticated task of measuring quantities off drawings or taking-off has progressed into the digital world. ICT is becoming a strategic property for any company to deliver business improvement in the AEC industry. Hence, QS organizations are encouraged to use the computer to execute traditional tasks. The following are some measurement software currently used in the marketplace.

With PriMus-DCF, everyone can start a DCF document and work on it openly (ACCA software, n. d. ).
According to ACCA software (n. d. ), PriMus REVOLUTION allows integrated development and handling of most estimating or job management documents, modified with the latest regulatory rules with the automatic generation of:
- BQ (forecasts, ensuing costs, work variance surveys, final accounting, quantity estimates, demands for proposal, labour incidence estimate, etc. )
- Measurement Book
- Accounting Register
- Cost Summary
- Work Improvement Statement
- Payment Certificate
- Steel Encouragement Pubs Requirements Book

- Weekly Lists of Individuals, Equipment and Costs
- Forms (completion of works, beginning of works, suspensions, resumptions, execution, etc. )
- History Management
According to the conducted study of Lim and Ong (2008), the dimension software continues to be not broadly use or completely utilised in calculating quantities for prep of BQ or other scope usages in local structure industry although most of the companies own it. Predicated on the opinions from the review, the common problems associated with dimension software are:
- The use of such software requires learning and keeping in mind many procedures
- Lack of flexibility
- Need to teach new staff to utilize the software
Using measurement software to take-off variety requires the taker-off to execute transferring of natural quantities from one software into another either digitally or personally to produce the quantities in the BQ format as compared to the manual method. Newer technology is being developed which allows seamless transfer of volumes from measurement software to the customised software for the prep of BQ. However, not all measurement software has the complete package of measuring and BQ creation software.
Most of the companies which using the measurement software would have to spend money and time to teach existing and new personnel to use the program before it can be utilised efficiently. The necessity of training also indicates that the training of quantity surveyors has not focus on this skill, as it has never been required. Nevertheless, a change to the education curriculum is necessary to produce QS graduates that are skilled in using dimension software now. The study also noted that it's difficult to check the measured amounts if the way of measuring is performed by using measurement software if weighed against the manual method. In fact, only staffs that are skilled in using it would be in a position to check the volumes easily.
Besides, the review also attempted to determine the features of measurement software as the next:
- Higher accuracy
- Ease in editing the measurement
- Increase velocity of measurement
- Easy to measure
- Reduction of Workforce
Most of the firms arranged that utilising measurement software in dimension of amounts produces high correctness. Measurement of volumes straight from digital format drawings cleans away the necessity to reproduce drawings in writing. Wheeler (1992) explained that duplication of drawing on paper will certainly reduce the accuracy of the drawings and measurement scaled from newspaper will further erode the accuracy and reliability (cited by Lim and Ong, 2008). Addititionally there is eliminated to faults due to real human error in reading the sizing off scale guideline and saving the dimension on paper or spreadsheet record.
Measurement software permits easy digital editing of quantities measured. It is because it covered function such as block, entity area, backup, paste, delete and undo as any other software that accomplish the editing process. In addition, application of measurement software will escalates the speed in measuring quantities when compared with manual method. This is due to the ability of the software to generate quantities. Recollection of computer also allows a program of instruction preserved and transforms it into fully automatic, after that it simplifying the works.
Finally, workforce required to measure volumes could be reduced by using dimension software. Most QS businesses have reduced the number of technological assistants specialising only in measurement of quantities in keeping practice. By using technology, the way of measuring work is now easier and faster however the skill needed in addition has evolved to a higher level consequently.
This chapter is approximately the current software and top features of measurement software and its impact on the building industry. Because of many business techniques are actually almost completely computerised and the trend is toward a larger computerisation of the rest of the processes, there might be a market in the use of dimension software for QS to carry out the works such as dimension, taking-off, BQ development, etc. more efficiently and speedily. This research also found that Microsoft Office Excel 2007, CATO Suite, BinaLink, and Buildsoft will be the common and popular way of measuring software have been used in local market.
Although there are range measurement software provided on the market and adopted in building companies, this research discovered that QS is apparently mostly of the professions that contain not been profoundly altered by the application of the technological progress proposed by digital trend especially in a producing overall economy like Malaysia. The largest impact of measuring software on QS practice had been on enhancing the quickness and efficiency of professional services. Information flows in development would increasingly be made electronically and a variety of measurement, estimating and costing procedures also would be done through the use of software programs.
