Project Procurement And Pre Tender Method Statement Construction Essay

Project Procurement And Pre Tender system acting direction Construction EssayContract procural has an impact on pouch performance in terms of hails, sequence and lineament. During one of the briefing meetings at the pre-tender stage of a social structure project, your Director has interest in collaborative procurance mode and need your advice. In addition, your Director has multiple sends release on at the same time and therefore m whatever set offices. Critic eithery explain why collaborative procural would be just between the invest offices to your Director.Masterman, (2002) defined a procurement system as, the organisational structure adopted by the client for the implementation, and at time eventual(prenominal) operation, of a project.While Love (1998) adopted the definition much(prenominal) that,It is an organizational system that assigns ad hoc responsibilities and authorities to people and organizations, and defines the relationships of the various elements i n the social organization of a project.There has been an increasing recognition that the conventional (traditional) approach to thrust procurement is inadequate (Rowlinson, S. 1999). However, it has been noted that there are still comparatively few procurement systems for clients to choose from. Each procurement system that is forthcoming delivers project success to a variable degree (Bowen, 1997).In to geezerhood context, it back tooth be seen that clients satisfaction is seen to be largely dependent on the filling of the most appropriate procurement methodology, and failure to select an appropriate procurement approach is recognized as a primary ca drop of a project failure (Masterman, 1996). However, which procurement route to undertake for a feature project be it expression or infrastructure browses depends on the objective and requirements in terms of its functionality, cost, time and quality set by the client. While the selection of an appropriate procurement system i n an congenital part of the building run, it is unlikely that an ideal procurement system that satisfies is altogether criteria ordain be available to go steady success (Winter, 2005).There are many factors that influence the project performance and gouge procurement for sure has an impact on costs, time and quality. However the procurement system entirelyow influence whether the project will be a separated procurement system (traditional), integrated procurement system ( convention build and its variant), management lie system (management contracting, pull management), or collaborative arrangement (partnering, Early contractile organ Involvement, ECI, e-tender). Figure 1 below shows the various forms of procurement systems.CLIENT receive/inexperiencePROJECT MANAGEMENT TEAM OPTIONSIn-house/external/in-house external procurance TYPESSeparated/ (2) integrated/ (3) management oriented/ (4) collaborativeSeparatedSingle-stage/ successiveTwo-stage/accelerated(2) IntegratedDi rect founding BuildCompetitive design buildDevelop constructTurnkeyBOT(3) Management OreintedManagement contractingConstruction managementDeep Marine(4) CollaborativeE-procurementParterningECIThe various procurement options available reflect the fundamental differences in the al localization of risk and function to match the characteristics of different projects and client needs (Winter, 2005). When client select the shell of procurement system to be use, strategic consideration must be considered especi every(prenominal)y at the stage on deciding whether to appoint a designer (architect/ direct), integrator ( affirmer), manager (project manager) or a group of all 3 reverse ating collaboratively.Under this approach the client can use any of the systems from any of the early(a) categories either singly or in combination, or even a bespoke system of his/her own devising but with the choosen systems(s) being implemented within a specific ambit controlled by the client.Coll aborative arrangement (Partnering) as required by the theater director has some benefits especially for multiple sites and with many site offices running at the same time. The benefits of time, cost and quality is explained below. expediencys of time several studies have indicated that by use the partnering approach the largest benefit is from the design and management processes were the flow of randomness between all parties helps to reduce the design times as designers and avower understand and are more efficient in work together. It gives for fast-breaking project times as the selection process is eliminated which can be costly and time consuming. The project can have an early swallow on site, shorter construction times and lower risk of time overruns. However, employ strategic partnering is more beneficial as it can achieve a 50% time saving it firms use the correct management procedures.Benefit to Costs. As partnering assures sure in the projects in terms of design an d construction results in fewer cost overruns, reduce claims and litigations and the project cost as well as reduced. This is one of the important part of the project where saving some of the cost can add value to other important flora that may be required at the end of the project.Benefits to quality Partnering can certainly improve the quality standards in building and there are indications that as a result, there are reduced number of defects, hence little rework is required. This is again another important aspect of the project where quality standard not only make but improved. Effective partnering relationships will as well as benefits from the RD and innovative thinking which assist to improve productivity and quality.trade union movement 2As part of the pre-tender process for a contract petition document, for multi-storey building projects for various sites, you are required to write a pre-tender method statement. Prepare a pre-tender method statement that you will sub mit with your telephone document.Pre-tender method statement is one of the important parts in the pre-tender process. Method statement is a document detailing how a particular project or activity will be carried out. Its detail the particular risk or danger associated with the particular parts of the project. However an assessment of construction methods to be considered during the tendering is required. The objectives of preparing a method statement are as followsTo change managerial experience to be called upon during estimating, a demand is created for in governing body relation back to performance. Managers find it is necessary to bring down resources, quantities and time in society to contribute.To modify data concerning new construction techniques and methods of handling materials to be included in an estimate. The method statement may be developed from work mull over data and planning cycles prepared for an alternative plant and labour situation.To abide the plant re quirements for a project to be summarized for inclusion in the contract preliminaries or plant schedule.To ensure the output and duration of different methods and machines is practicalally matched.To give guidance to the estimator on specific on specific bill of items relating to plant and labour requirement in order that realistic rates may be built up.In this case study, a pre-tender method statement is to be prepared as part of the pre-tender process for a contract bid document for multi-storey building projects for various sites. conglomerate formats for method statement can be used like a pre-printed standard format that has been designed for repetitive works for familiar design such as in this case-study.Information that is required on method statement includes the operation or work stage. Each operation requiring abstract of plant or method should be listed in the method statement, for subject excavation work, formwork, concrete handling and placing, choice of plant for l ifting precast floors or erecting steelwork.Quality of work is also required where this is directly stir methods of construction, number of man- male monarchs and machineries. Realistic methods of construction together with constructive alternative and sequencing of trading operations should be outlined clearly.The summary of plant will assist in the preparation of the preliminaries plant element where an example is tabulated in the table below.S/NoOperationQuantitymethodSequence of operations whole kit and caboodle and laboroutputduration1 turn up over-site to reduce levels and aim to tip70 x 100 x (ave.) 450mm = 3150 m2Excavate using hydraulic forcefulness shovels.
