The study also showed that 4 of the 5 developers who were part of the study had used construction methods that were not certified. Advantages found in the study were that these alternative construction methods were cost-effective on the part of developers, enhanced speedy delivery, and some construction methods were found to be easy to maintain. The disadvantages were the inability of the houses to resist extreme weather conditions, structural defects such as cracks that are not easy to repair in some materials, poor workmanship, and structures that are not compatible to future extensions (Mgiba, 2007: 16).

2.4.1.2 Inadequate Material

According to Metri, 2005 supplier quality management includes fewer dependable subcontractors, reliance on suppliers process control, strong inter dependence of supplier and customer, purchasing policy, emphasizing quality rather than price, supplier quality control and supplier assistance in quality development. Materials are often a major source of quality problems and affect buyer satisfaction. Instead of relying on tools such as acceptance sampling to establish the quality of incoming materials and component parts, it is preferable for constructors to purchase from a more limited number of qualified or certified suppliers. …show more content…

From the time that a building's construction process is finished the process of decay starts slowly even though we caru1ot really see it but it is present. The Environmental factors and weathering are forces of nature which we as human beings cannot really control but we can try and design against them appearing and causing the buildings to deteriorate.

It introduces integration between both the design and construction teams in order to have an end built product of lower costs, higher quality, shorter time and efficient design. Constructability principles could be applied to small, medium, and large scale projects. They have a significant effect on the overall project performance in terms of cost, time and quality. The purpose of constructability principles is to identify design errors, unclear design aspects, features that could be difficult to implement or very expensive. Applying constructability to construction projects has proven many advantages to the construction industry. The value added of applying constructability to construction projects was the reason for the wide spread of constructability...

Case of the Proposed Jiminy Peak Wind Turbine

...1. Two commonly used methods of financial analysis are payback and present value. Payback determines the length of time for an investment to return its original cost (1). Using the assumptions stated below the payback of the Jiminy Nick wind turbine with a cost of about $3.3 million would return the investment in about four years time. Net present value summarizes the initial cost of an investment, the estimated annual cash flows, and expected salvage value, taking into account the time value of money (1). A NPV calculation for the scenario SED is reviewing equals $7,697,286 minus the investment costs of $3,318,000 totaling $4,379,286. The capital budgeting analysis reflects the assumptions stated in the case scenario that the initial investment cost and installation of the wind turbine is $3,900,000 and there is a grant available from the Renewable Energy Trust Fund in the amount of $582,000. A bank loan of $3,300,000 at 7.3% will be obtained leaving an $18,000 difference. The turbine will follow MACRS double-declining balance depreciation schedule for a period of five years including half-year depreciation in the first and last recovery years. Jiminy Peak has an income tax rate of 40%. The company has sufficient taxable income to benefit from any deductions and credits available, and the after-tax weighted average cost of capital of 6%. The turbine’s useful life is 25 years with no terminal disposal value. There will be $100,000 net cash inflow from extended operations and...

Flexible pavements structures comprise of more than one layer of different materials placed on a prepared subgrade. This type of pavement structure is known as an elastic layered system. This means that when a load is applied to the pavement the pavement will deform, but as soon as the load is removed the pavement will return to its original shape. However, at a certain point, the pavement will no longer be able to return to its original shape and as a result permanent deformation will occur in the form of rutting or...

As reported by Somerset College (2015) the College was founded in 1856 originally with its roots being in Science and Art. It eventually merged with the Technology School in the 1970’s and settled on the site the community are familiar with on Wellington road. One of the Colleges main aims is to create a College that produces students who are ready for the workplace. In September 2013 the new Industry Skills Centre was opened; this centre focuses on Automotive and the vocational Construction trades. A Colleges survival is dictated by student numbers which in turn links into funding, however a successful College will have quality teaching staff that have appropriate teaching qualifications as well as vocational experience. The Learning and Skills Development Agency (2005) published a research project centred on Recruitment and Retention of individuals with industrial experience. The paper speaks of good practice in retention such as professional development e.g. teaching qualifications, teaching pay initiatives, enhancing pay and flexible working. The aim of this report is to: establish why, after implementing the best practice cited in the LDSA report- Strebler et al (2005), is Somerset College unable to retain lecturers in Construction?

Contract Procurement Options

...have not changed significantly in the last 25 years, though time and cost overruns are still prevalent throughout the industry (Smith and Love, 2001). In a response to reduce the incidence of time and costs overruns, the disputes that may often arise, and the likelihood of project success, alternative forms of procurement method such as partnering and alliancing have been advocated (Love et al. 1998).
