Investigating The Criticality Of Potential Causes Of Delay

Describe common practices to estimate the duration of project activities as well as real reasons that cause project delays.

My partners and I have made a list of areas that might cause the project delays or failure with their respective outcomes. We have listed the risk below that can prevent the project to finish on time.

Research is conducted to examine different points of views of the importance of performance outcomes in a construction project in Hong Kong. ANOVA was used to analyse the data relative to how the performances were measured. Performances were measured using a performance criteria starting with the most important first, which is time. Timely completion of a project would prevent loss of revenue and penalities to the contractor.

In step 3, the organized data gathered in step 2 is reviewed and analyzed, looking for factors which can be changed to in order to improve the situation. Moreover, we want to verify that problems identified, are most certainly causes to the problem. It is pointless to change a factor that has no direct effect on the problem. The tool that is most useful in step 3 is the cause and effect or fishbone diagram. Furthermore, statistical experiments can be used to correlate relationships between identified factors with the results in the form of scatter plots.

Though speeding the process is not always an option, it can aid in finding problems sooner and avoiding time delays later. "Another reason for reducing project time occurs when unforeseen delays—for example, adverse weather, design flaws, and equipment breakdown—cause substantial delays midway in the project. Getting back on schedule usually requires compressing the time on some of the remaining critical activities. The additional costs of getting back on schedule need to be compared with the costs of being late (Gray and Larson, 2003)."

Projects that have insufficient recourses from the beginning will cause stress among the construction professionals. This may create a better working environment, as it will allow employees to have an adequate workload as well as a suitable amount of work responsibilities. Besides this, there is a need to clarify what is expected from each employee in his or her position. Job instructions and goals must be explicit for professionals, in order to minimize unhealthy distress and increase efficiency.

can only be computed if there is a strong linear relationship exists between x and y

The BBC (2004) also suggested that the main cause of the delay in the project finalisation was due to the “production of detailed designed variations and the late supply of information during the construction process”. The deadlines which the project manager provided for the construction of the parliament building were very tight. The BBC (2004) argues that these deadlines did not reflect the complexity of the building which resulted in both architects and trade contractors failing to deliver critical foundations of the project therefore meaning the project timescale overrun. The project manager failed to realise the unlikelihood of the targets set being achievable and therefore failed to alter the timeline to reflect this.

Keeping all this in mind, builders have to work alongside clients to satisfy their project needs. Projects are also being built quicker because of the demand to occupy them instantly.

While describing the independent variables chosen, we have to consider that some are latent nature, meaning that the underlying concepts cannot be measured directly. In order to create a meaningful value for said variables, we carried out a factor analysis with the aim of extracting two factors. In our analysis we also included 3 dummy variables, one single variable and the usual control variables. A brief

1. Response Rate and Category: The main survey questionnaire was personally handed over to the respondents. It was distributed to 50 carefully selected construction industry professionals representing Clients, Contractors and consultants. Completed forms were requested to be collected later. Over a period of time after distributing the questionnaire, 38 responses were received and the composition of the respondents is given in Figure 2.

The aim of this analysis is to identify factors influencing labor productivity in building construction with attention on formwork operations and to understand its variations attributable in direct impact on labor productivity. This research focuses on determining the relationship between various attributes which effect labor productivity by collecting real time responses from job site. It is to be done by taking

The three topics listed above are all very important aspects that are included in all engineering and construction projects. These aspects are all handled in costs effective manners as well as with the ultimate safety in mind. Operating on the construction side of projects can be very dangerous, but today’s world has come a long way to ensure that safety is a top priority. The job site layout is an important step that is continuously changing throughout the entirety of the project. When choosing the site many aspects must be taken under consideration, including: structure size, location of adjacent roads, soil conditions, construction schedule, and many other aspects. Once a site is chosen the client must provide the contractor with proper parking, sanitary facilities, trailers, and material storage in order to keep the construction going at the scheduled pace. If any of these factors are missing from the job location site it can force the project to take longer and in turn cost more money to the client in most cases.
