A catastrophe is a natural or semisynthetic event that negatively affects life, belongings, support and industries. Sri Lanka is prone to natural catastrophes such as inundations, landslides and drouths. In December 2004 Sri Lanka was impacted by tsunami of unprecedented magnitude which affected the state really significantly. The coevals of solid waste as a consequence of catastrophes is a important job and direction of these wastes is really critical.

Research Aim

Aim of this survey is to place the station catastrophe constructing waste direction schemes and issues at regional degrees in Sri Lanka.

Research Aims

To reexamine the “ Building Waste Management Systems ”

Evaluation of catastrophes occurs during last 10 ( 10 ) old ages to place their behaviors at regional degrees.

Explore the edifice waste direction schemes adopted at selected regional degrees.

Critically evaluate and place the issues that arose when implement the station catastrophe constructing waste direction schemes at regional degrees.

To pull decision sing the station catastrophe constructing waste direction schemes and issues at regional degrees in Sri Lanka.

Research Methodology

Research design outlines the program from the research inquiry to decision. It deals with the logic scientific enquiry, scheme for proving the hypothesis or in interpretative work to understanding the phenomenon ( Tan, 2002 ) .

Literature Review

For this research, a comprehensive literature study will be carried out on natural catastrophes, catastrophe direction and post-disaster waste direction both in planetary and Sri Lankan context, through books, diaries, studies, newspapers and World Wide Web.

Case Study

After set up the research job through literature reappraisal, the following measure is the instance survey design. Harmonizing to Yin ( 1994 ) , a carefully design instance survey can increase the generalisability of the survey, which is one of the chief unfavorable judgments over the instance survey attack. Therefore, a particular attention will be taken to heighten the generalisability when planing the instance survey. The process which will be adopted in planing the instance survey including the designation of analysis method, specifying the figure of instances and choice of instances.

The intent of the instance survey is to derive in deepness understanding about the significance of the topic being studied, concentrating on procedure instead than outcome, on find instead than verification. Case choice is an of import facet particularly in instance survey method and it has to be based on the theoretical instance choice ( Yin, 1994 ) .

Case survey on station catastrophe constructing waste direction in Sri Lanka at regional degrees during last 10 old ages will be see for this research to derive in depth apprehension of waste direction schemes used and issues aroused at regional degrees. Three types of catastrophes such as inundation, landslide and Tsunami will be selected for this research which will be more frequent and critical catastrophes during last 10 old ages and two parts will be selected from each type of catastrophe which will be immensely affected among other parts.

Data Collection

Yin ( 1994 ) has identified six beginnings of informations aggregation under instance survey attacks, viz. ; paperss, archival records, interviews, direct observation, participant observation and physical artifacts. Out of these techniques, interviews will be used as the chief informations aggregation tool as, it is the most accessible and low-cost method when sing the fortunes which the research has to be carried out.

By and large interviews are three types as structured, semi-structured and unstructured. Structured interviews allow research workers great control over the sample of the respondents while semi-structured interview provides much more range for the treatment and recording of the respondent ‘s sentiment and positions ( Shajahan, 2004 ) .

Furthermore the information needed to be collected from organization/individual in this research is largely qualitative and drawn-out ; therefore it would hold been hard to roll up it utilizing standard questionnaire. Therefore, semi-structured interviews will to be the most suited method of primary informations aggregation for this survey.

Semi-Structured Interviews

This mean that the researches has the picks of excluding some inquiry in peculiar interviews, given the specific organisational context that is encountered in relation to the research subject. Furthermore, extra inquiry may be required to research the research inquiries and aims given the nature of the event within peculiar organisations ( Remenyi and Williams, 2003 ) . Semi-structured interviews have the flexibleness to let the research workers to so such alterations. For this research semi-structured interview will be held with stakeholders who involve in the station catastrophe constructing waste direction in Sri Lankan regional degrees.

Interviewees were selected from the top or in-between direction every bit good as field officers in both authorities and non-government organisations who involved the station catastrophe constructing waste direction procedure.

Datas Analysis

There are several methods to analyze qualitative informations such as textual or content analysis, mapping techniques and unite textual & A ; mapping techniques.

Contented analysis is a method of analyzing written, verbal or ocular communicating messages ( Cole, 1988 ) . It is used to find the presence of the certain words or construct within text or set of texts. There are fundamentally two attacks to content analysis. One attack is called as word based analysis or quantitative content analysis. It considers the frequence of word use.

The 2nd attack is analysing content by coding ( qualitative content analysis ) , which was adopted in this peculiar research. This attack overcomes, losing the context, which is major drawback in word base method and by happening similar knowledges under same construct.

For this survey, code-base content analysis will be really much suited, since the interviews were semi-structured, which had unfastened ended inquiries besides. It breaks seeded informations into sections with the intent of forming informations to do them easier to construe and to place construct ( Catterall and Maclaran, 1996 ) .


Title of Research: Hazards or factors impacting success in D & A ; B Projects

The Design and Build procurance system is one of the systems that advocated get the better ofing the insufficiency with the traditional procurance method. It is now, regarded by bulk of clients because it is offering greater assurance to clients. But nowadays it is traveling to cut down because there are several factors impacting to the design and physique undertaking.

Research Aim

To reexamine the “ Design and Build Procurement System ”

Explore the cardinal and Practice of design and construct procurance system.

To place the advantages and disadvantages of Design and Build.

Identify the factors or hazards in success of design and construct building contract.

To reexamine the hazard direction system

Examine factors or hazards affect in design and construct contract of client ‘s, contractor ‘s and end-user ‘s point of position.

Collect current informations from the United Arab Emirates building industry and analyse the informations and decision about hazard and their direction.

Research Methodology

Best methodological analysis is an of import to make the thesis research because it gives smooth map to make the clear analyze. The treatment begins with a ground for the pick of overall methodological analysis, followed by the pick of more specific methods.

Research design is the program for acquiring from the research inquiry to the decision. It deals with the logic if scientific enquiry, a scheme for proving hypothesis or in interpretative work, for the research in order to accomplish a successful completion. Harmonizing to Zhang ( 2004 ) Questionnaire study is an effectual, convenient, and economical fact-finding tool for obtaining informations and trying the sentiments of persons in spatially diverse locations in a comparatively short clip. Therefore, questionnaire study and few unstructured interviews will be selected as appropriate techniques to accomplish the purposes and aims for the research survey.

Literature Review

The literature reappraisal will be carried out chiefly utilizing books, diary articles, research documents, thesiss, World Wide Web, newspapers etc. The literature hunt will be made more specific and more focussed on, design and construct procurance system and hazard & A ; hazard direction system in the design and physique system.

Whilst transporting out the literature reappraisal much attention will be given to instill appropriate comprehensiveness and deepness ; asperity and consistence ; lucidity and brevity and effectual analysis and synthesis. The literature has been evaluated, analysed and interpreted in a mode to protect the above mentioned belongingss. The synthesis of literature reappraisal will give rise to research inquiries.

Data Collection

The manners of informations aggregation for this research will be through questionnaire study. There are two types of questionnaire study available these are ;

Open-ended Questions

Closed-ended Questions

Multiple pick Questions

Open-ended Questions

Open-ended inquiries are inquiries to which there is non one definite reply. Open-ended inquiries may be a good manner to interrupt the ice with a study, giving respondents an chance to reply in their ain words. The drawback to open-ended inquiries is that the responses are more hard to catalogue and construe. ( Fink, 2003 )

Closed-ended Questions

Closed-ended inquiries have a finite set of replies from which the respondent chooses. One of the picks may be “ Other. ” It is a good thought to let respondents to compose in an optional response if they choose “ Other. ” The drawback of closed-ended inquiries is that they are more hard to compose than open-ended inquiries. This is because the judge must plan picks to include all the possible replies a respondent could give for each inquiry. ( Fink, 2003 )

Multiple Choice Questions

Multiple pick inquiries allow the respondent to choose one reply from possible picks. This type of inquiries find out more inside informations than closed-ended inquiries and the consequences can be compiled more easy than open-ended inquiries.

In general, the questionnaire design for this research consist open-ended, closed-ended and multiple pick inquiries. For this research survey is seeking to get a just and balance response from a assortment of professionals with broad runing experience of the building industry, and for this ground, questionnaires were considered a more suited tool for this analyse due to the nature of information.


Title of Research: Hazard Management Practices of Road Undertakings

Risk Management in building undertakings has been recognized as a really of import direction procedure in order to accomplish the undertaking objectives in footings of clip, cost, quality, safety and environmental sustainability. This survey explores risk direction patterns in route undertakings in UAE with the position of a undertaking life rhythm.

Research Aim

The purpose of this survey is to place and measure the Risk Management patterns of route undertakings in United Arab Emirates with the consideration of project life rhythm.

Research Aims

Identify the types of hazard variables in route undertakings concurrence with the different stages of a undertaking life rhythm.

Identify and analyze the critical hazard factors in each stages of a undertaking life rhythm.

Identify the hazard response steps used for each hazard factor in each phase by undertaking parties.

Identify the barriers to put on the line direction pattern and the solutions to better the ability to pull off hazards.

Develop a hazard direction model for pull offing hazard in different stages of a route undertaking.

Research Methodology

A comprehensive literature study will be carried out by mentioning a scope of books, diaries, articles, thesiss and World Wide Web to place and measure the assorted hazard factors that associate with building undertakings, hazard response steps to each hazard factor and barriers to put on the line direction. The literature reappraisal will be used to place the definitions related to hazard and hazard direction, types of hazards and practical extenuation steps.

Delphi study will be carried out in order to place the types of hazard variables in concurrence with the different stages of a undertaking, every bit good as to gauge the degrees of significance of each hazard factor in the several undertaking stages, place the response steps for each hazard factor and place the barriers to put on the line direction. It will be carried out by giving a series of questionnaire with a feedback of old unit of ammunitions. The questionnaire will be designed based on the cognition obtained from literature reappraisal, interviews and treatments. In order to analyse the informations Relative Importance Index ( RII ) was adopted for this survey.

Kerzner ( 2001 ) has stated that Delphi method as adept judgement technique, giving one of the comprehensive surveying techniques used in placing hazard factors. Further Dey ( 2002 ) has stated that Delphi method is one of the effectual techniques in designation of assorted hazard factors and analysis tool, being used by research workers and practicians.

Delphi Technique

“ The Delphi technique is a method for the systematic aggregation and aggregation of judgements from isolated anon. respondents on a peculiar subject, through a set of carefully designed consecutive questionnaires interspersed with summarized information and feedback of sentiments, derived from earlier responses ” ( Chapman, 1998 ) .

The Delphi method is a mature and a really adaptable research method used in many research spheres by research workers across the Earth. The Delphi method is good suited as a research instrument when there is uncomplete cognition about a job or phenomenon ( Skulmoski et al. , 2007 ) .

The Delphi method can be characterized as a method for structuring a group communicating procedure so that the procedure is effectual in leting a group of persons as a whole to cover with complex jobs. Panel members remain unknown to one another and respond to a series of questionnaires. The iterative nature of the process generates new information for panellists in each unit of ammunition, enabling them to modify their appraisals and project them beyond their ain subjective sentiments ( Chan et al. , 2001 ) .

Fowles ( 1978 ) describes the undermentioned 10 stairss for the Delphi method:

Formation of a squad to set about and supervise a Delphi on a given topic.

Choice of one or more panels to take part in the exercising. Customarily, the panellists are experts in the country to be investigated.

Development of the first unit of ammunition Delphi questionnaire

Testing the questionnaire for proper diction ( e.g. , ambiguities, vagueness )

Transmission of the first questionnaires to the panellists

Analysis of the first unit of ammunition responses

Preparation of the 2nd unit of ammunition questionnaires ( and possible testing )

Transmission of the 2nd unit of ammunition questionnaires to the panellists

Analysis of the 2nd unit of ammunition responses ( Stairss 7 to 9 are reiterated every bit long as desired or necessary to accomplish stableness in the consequences. )

Preparation of a study by the analysis squad to show the decisions of the exercising

Delphi Method Design Considerations

While the Delphi method is flexible and superficially simple, many design considerations needs to take into history in order to successfully utilize the method. Ill applied like any other research method, the Delphi can give fishy consequences.

The figure of unit of ammunitions once more is variable and dependent upon the intent of the research. Delbecq et Al. ( 1975, in Skulmoski et Al. 2007 ) suggests that a two or three loop Delphi is sufficient for most research. In this research it was limited to three unit of ammunitions of Questionnaire Survey. The questionnaires are designed to concentrate on jobs, chances, solutions, or prognosiss ( Skulmoski et al. 2007 ) .


There are three research subjects selected in this study and each subject contains aim, aims, research methodological analysiss, informations aggregation, analysis and reading in relation to the purposes and aims of each subject. The first research subject is post catastrophe waste direction in building industry based on Srilanka. Literature reappraisal, instance survey, semi structured interview and code-base content analysis etc. will be used for achieve this research. The 2nd research subjects is hazards or factors impacting success in design and construct undertakings based on UAE part. Literature reappraisal, questionnaire study etc. will be used for achieve this research purpose. The 3rd and concluding research subject is risk direction patterns of route undertakings base on UAE part. Literature reappraisal, Delphi study ( three unit of ammunitions ) etc. will be used for achieve this research purpose.
