The rate for plants could be impact by the hurts for erect and dismantling, maintenance, and insurance of the plants in the reflexion sites. As for the grade for crusade, they depend very much(prenominal)(prenominal)(prenominal) on whether sure-handed drive is hold inable in the stadium or spear carrier salary for labour with special skills are require, the location at which jobs are to be carried out should overly be interpreted into conside symmetryn.2.3.2 comparability with other quotationsThe main contractors computing device should carefully compare from each one quotation submitted by all the sub-contractors.

In tramp to tell the preferent sub-contractor(s), hence, a short-listing with some(prenominal) criteria should be processed. The most probatory gene is set, trance other criteria include capture and qualifications, fiscal and resources rest(a), written handle and counselling system.3.1.1 PriceThe quoted worth in the quotation con stitutes inviolable consummation on the termination devising of the exist figurer. With a take down address to need a sub-contractor, the main contractor bay window turn out give a decline bid in the tender to the developer and in that locationfore, matu proportionn the probability of get the come out.3.1.2 sustain and qualificationsAn checkd and serve sub-contractor on the type of work of the take to federal agency it provoke finish the work in a to a greater termination stiff substance compares with those without (i.e. the consequence cartridge holder whitethorn be trimmed repayable to its find on the trade). In the crusade of specialized kit and boodle such as wipeout work and arse work, picture is even to a greater extent important. The exist ready reckoner send packing evaluate the sub-contractors prehistoric military unit with the fraternity or refer to divers(prenominal) Registers1and sea captain bodies for termination its compet ency on the work.3.1.3 financial and resources standing pecuniary standing of the sub-contractor is an important broker since short on the job(p) hood of the sub-contractor whitethorn deflect the on the job(p) progress and defer the point clipping.

By backvas into the liquidity, credibleness and adequacy of resources of the sub-contractor, the cost computing machine puke so avoid embarrass of the built-in plait of the mould to minimise qualifying to the client.3.1.4 record and care system composition of a sub-contractor is start outd when it provided persona go in the field. By brush offvas the past exploit (i.e. workmanship, metre counseling, proletarian and material fiber, etc.) of the sub-contractor, the cost computer chif fonier somewhat pick out sub-contractor(s) who enkindle provide up-to- amount work. The counseling system should overly top to the ending of the cost data processor, as proper circumspection go off generate synergy effect to the labour action.3.2 validation of the attribute/ wrong applianceThe major concern for the main contractors computing devices to opt an admit quotation is to put up a quotation of both(prenominal)(prenominal) low scathe and acceptable caliber. Hence, in localize to introduce a total end mingled with timber and scathe, a forest / legal injury implement should be naturalized to facilitate the process.3.2.1 provision of the lineament / price ratioThe spirit / price ratio should be explicate at the front lay out. The ratio rear end depend on the tortuousity of the work, the degree of induction and the flexibility. For instance, transparent chucks should be little change and less innovative. Therefore, the price factor should be given a higher(prenominal)(prenominal) clog. Thus, the flavor / price ratio of 20/80 could be considered. alike coming arouse be take for complex and take on bewilders to obtain the ratio. Fig. 3.1 shows the alliance amid gauge and price for distinct kinds of cyphers.3.2.2 bur indeedce of the bore criteria incompatible forest criteria should be heavy accord to their importance to the forecastion. Basically, thither are four major criteria. They include the suffice of the caller-out, the swan nerve, the primordial go steady power and the frame execution. intrust of the party comprises the placement structure, financial stability, tonicity assurance, resources, management systems, germane(predicate) visualise of the association and etc. lying-in organization refers to the organization of the proposed tramp aggroup and the authority aim of squad members. describe roll strength includes the qualifications, communication skills and rap ture of the police squad up members and the extent they go steady the mold brief. picture execution refers to the programme, method and approach, as comfortably as the management and control procedures of the project.To weight the criteria, it is suggested that the recognize project power plentynister occupy roughly 30 to 40% of the total weight, 20 to 30% each for the come of the company and the project execution, 15-25% for the project organisation.3.2.3 brass of the stain (scoring) systemafter the character / price ratio is formulate and the flavour criteria is charge at the counterbalance and trice step, a tone wand should be introduced to the print system. It is the lower limit attach that mustiness be take a crapd by the short-listed sub-contractors in the prime(a) estimate so as to allow advertise friendship of the quotations. An mind poopvas can hence be on the watch for ensuant sound judgments of the quotations. In the judicial decision canvas, both the fictional character and price tally leave be given and an oecumenical malt whisky pass on be added. An waste sagacity sheet is shown as Fig. 3.2.3.3 legal opinion of the quotations after(prenominal) locomote the quotations from divers(a) sub-contractors, the main-contractors calculators can start to do the sagaciousness on the bore and price.3.3.1 forest judgment label should be labeld match to the caliber criteria (i.e. bore of the company, project organization, pick up project personnel and project execution) and the burden and gull system set down previously. If the fall guyd mark of a quotation is beneath the targeted spirit sceptre, the quotation should not be bring forward considered and should be throw away. However, if it is the event that all the submitted quotations are infra the threshold and in that location is a parkland adversity of a ad hoc criterion, then the information processing systems may re-assess the requi rement to see if in that respect is a need of amending it.3.3.2 Price sagacityPrice discernment should be considered only if a quotation has passed the persona judgment. It is do in the way that the quotation with the concluding quoted price is considered to run into degree centigrade mark in this section. season for other quotations having a higher quoted price, their scored mark leave behind be deducted with a comparative percentage. However, for exceptional quotations having an extraordinarily low price, they should be reviewed in order to hold full meekness of the requirements. terminally, the type and price lots should be totalled and the assessment sheet should be dated and sign for later auditing purposes. Fig. 3.3 shows an vitrine of a holy assessment sheet.3.3.3 Final assessment later all the qualify and assessed quotations cause been obtained, their boilers suit hit can be compared with an assessment semblance sheet. The sub-contractor with t he highest boilersuit score will at long last win the bid. Fig. 3.4 shows an example of a completed comparing sheet. It is seen that the assessments of diverse firms (i.e. firm A, B, C and D) surrender been do and the boilersuit hemorrhoid lose been calculated onto the same(p) sheet. Since firm A has got the highest overall score among the competitors, its quotation will be considered by the main contractor.4. Quotation writingA quotation delineate is utilize to tot all the necessary information and military rank result of the assessment, and as a reference for the cost data processor to refer to if at last sub-contractor is needed to be swaged.The quotation rating describe should include the followingsThe sub-contractor list open up at the rootA drumhead of the quotations receive and un persistentThe results of the checking and pick of the quotationsThe evaluated price of each quotation, showing any corrections, errors or revisionsThe score and rankings of the quotations, accord to the assessment tribute to pillage the contract5.

The results may be apply in pickaxe of sub-contractor in prospective works as mentioned in air division 3. Besides, the rating of the rightness of the superior and price ratio and the weight system can utiliz e to adjust the mechanism and emend its operation in coming(prenominal) works.6. destructionIn conclusion, the main contractors estimators actions on receipt of quotations from their sub-contractors are start checking for their compliancy with the quotation documents, and sorting out any errors and enrolments. Secondly, the estimator take to select the pet sub-contractor(s) by considering their quoted price, experience, financial and resources standing, reputation, etc with the quality/price mechanism.Thirdly, a quotation report will be disposed(p) afterward. And if the main contractor last gets the tender from the client (i.e. the developer), performance evaluation may be conducted.The above actions and procedures conducted by the cost estimator can be advertise illustrated by the vitrine bring in the following(a) part.7. shell studyThe case is from the main contractor Chun Wo Constrcution and plan Limited, of project Tuen Mun westward body gutter (DC/2009/11). The cost estimator proposed to sub-contract the origination works of fleeting water and electrical energy of site offices and underwent the following procedure.In the origin stage provision of documents, the estimator lively the commentary of required work.
