Adaptability of a new national building code to the building sector in Sri Lanka
(2024) De Mel, CD; Disaratna, V
Building Construction is one of the main economic activities where planning, designing, construction, funding and maintenance are included in completing a building project. Building controlling systems (BCs) have been identified as a necessary engine of global economic progress. Therefore, need arose to establish an important guideline for ensuring safe, innovative, energy and cost-effective building construction. Many countries utilize building codes to meet key requirements for health, safety, well-being, of people and the built environment. After facing many disasters Sri Lankans have understood the absence of a national building code. This study identifies six objectives after identifying the problem to examine the adaptability of a new National Building Code to the Building Sector in Sri Lanka. Lack of building code and awareness is noticeable as a gap in Sri Lanka and need for a National Building Code for building sector was significant. To address this gap as a problem, the researcher conducted qualitative research including semi-structured interviews to collect data and three main construction professions were identified, namely Chartered Architects, Chartered Engineers and Chartered Quantity Surveyors. Primary data collection method and a literature review as secondary data collection method. The respondents were identified by using the snowball sampling technique since the population is not précised and sample is limited to 12 participants in saturation. The data collected was analyzed by using manual content analysis. Research findings revealed the answers for the six research questions derived from the research objectives. The findings of the study reveals that, the Sri Lankan government will have to take major action in making awareness of the opportunities and challenges in future, to adopt a National Building Code to protect public health, safety, and well-being while lowering disaster risk and working towards a sustainable built environment. At the conclusion findings were presented as what is a building code ? Impact created by a building code, functions, opportunities created, challenges faced and recommendations to overcome those challenges were presented accomplishing the objectives.

Analysis of survival factors of subcontractors in economic recession
Misbah, ASM; Disaratna, V; Ganeshu, P; Nazeer, FS
Subcontracting is a term which means giving a portion of the work or obligations to another party called as subcontractor (SC) under a contract. This was used in several industries but in the construction industry, it plays a vital role to complete the project with a higher quality of output. In gross domestic product (GDP) calculation of the national economy, the significance of the construction industry is very high. When a country faces an economic recession, it has a direct impact on the construction industry and the stakeholders of that industry. A small number of researches was available regarding how the construction firms handle the external changes like economic recession. In this respect, this research analyses the key strategies used by the SCs when they face an economic recession. Purposive sampling method was used for data collection and a questionnaire survey was selected as the basic technique to collect data. The respondents were first asked about their profile and then about the effect of recession and survival strategies in economic recession. Relative Importance Index (RII) method was used to rank the effects and the strategies according to its importance given by the respondents. Findings of the research were that there are various strategies which are most important to the survival of subcontracting firms “Increasing the focus on forming relationship with main contractors”, “maintain goodwill to get additional financial support from bank”, “Implementing stricter site management to reduce material and time wastage”, “Implementing stricter financial management on company cash flow”, and “bidding for more projects that are within the firm’s resources and capabilities”. Finally, practicable suggestions were identified for SCs to survive in the construction industry during the economic recession period.;.

(Ceylon Institute of Builders, 2017-06) Udayangani, KDMS; Disaratna, V; Wimalasena, NN; Ranasinghe, U; Pilanawithana, NM; Sandanayake, YG; Ramachandra, T; Gunatilake, S
The concept of condominium has gradually increased as a solution for the housing demand in Sri Lanka through the past few decades. With the development of the condominium sector Condominium Management Authority of Sri Lanka was established as the governing body of both the private and public condominiums in country. The Apartment Ownership Law (AOL) was enacted as the regulation for the condominiums by Act No 11 of 1973. The Apartment Ownership Law has amended several times up to its last amendment in 2003. According to many writers there are many issues raised in the condominium sector and the provisions provided in the AOL are not enough to solve those issues in several situations. Furthermore, lack of research could be found about the gaps in Apartment Ownership Law of Sri Lanka. Therefore, this research study was conducted in order to find the gaps which exist in the Apartment Ownership Law of Sri Lanka. A comprehensive literature survey was carried out to find the theoretical background and Interview survey was carried out through experienced professionals in condominium sector as well as legal sector. According to the findings of the research there are gaps in provisions relating to many areas such as compulsory registration of condominium, common properties use and enjoyment, scattered housing properties, mixed development condominiums, developers obligations and sub management corporations. Finally, suggestions were made to rectify the identified gaps in AOL.

Impact of ineffective tendering processes on construction projects
(Ceylon Institute of Builders, 2018-06) Srimal, NAJN; Disaratna, V; Ganeshu, P; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
Tendering process is the method adopting in procurement for the selection of the contractor, who is responsible for carrying out the construction works. The tendering process is built up with several functions, performed by main tendering stakeholders. Certain substandard practices of the stakeholders during the tendering process create an ineffective tendering process. It directly results in adverse outcomes during the post contract stage of a construction project. Due to the high involvement of these ineffective tendering outcomes, the construction project is impacted adversely and may fail in fulfilling the project objectives effectively. The research investigated the impact of the ineffective tendering process to the construction project and it was equipped by questionnaire survey while the analyses are carried out in a specific analysis method developed for this research. Initially the research found the contribution of the substandard practices to cause the ineffective tendering process. Then the probabilistic impacts to the construction project were investigated through the probabilistic outcomes from the ineffective tendering process. Additionally, the research has brought some effective solutions to mitigate ineffective tendering process. The findings of the research indicated that the effect from the ineffective tendering process to the construction project can be mitigated by properly following the governing tender rules, adhering to good codes of conduct and ethics, managing the future risks during the estimating process by the bidders and maintaining better communication during tendering.

Impact of schedule compression on successful delivery of Sri Lankan construction projects
(2018) Wickramasinghe, BMSM; Disaratna, V; Samarawickrama, S.
Scheduling is the most critical aspect to be considered in construction planning. When the project is slipping over its planned schedule, delay becomes reality. Delays in construction is one of recurring problem that can challenge on successful delivery of projects. Also delays are subjected to generate a considerable amount of financial losses to the contractors. Accordingly, if such situation is encountered the contractors are usually compelled to accelerate the projects. Previous researchers have stressed schedule compression as a commonly used approach to expedite the construction to recover lost time due to delay or to meet revised deadline during an extended project duration. However, when expedite the project, though the time saved, other performance parameters are often sacrificed for the sake of remaining ahead of the schedule. Therefore, this research aims to explore the impact of schedule compression on successful delivery of Sri Lankan construction projects. To accomplish the aim, ten semi-structured interviews were conducted with experts including Quantity Surveyors, Contract Administrators, Project Managers and Engineers. Subsequently, the gathered information was analysed rigorously through content analysis and explored that, acceleration through schedule compression creates negative, positive and neutral impacts on project performance parameters in terms of cost, quality and health and safety.

Implementation of government policies in the construction industry: The case of Sri Lanka
(Istanbul Teknik Universitesi,, 2022) Mendis, APKD; Jayatunge, DASR; Disaratna, V; Perera, BAKS
Public policy system of the construction industry of a country will reflect the country’s economic, political, social, and cultural status. In any country, especially in developing countries like Sri Lanka, the success of government policies depends on their effective implementation. Thus, the aim of this study was to explore how construction related government policies could be effectively implemented to facilitate the development of the construction industry of Sri Lanka. The study used the qualitative approach consisting of 15 expert interviews and manual content analysis was used to analyze the empirical data collected through the interviews. The findings revealed that National Policy on Construction (NPC) formulated by the National Advisory Council on Construction (NACC) is the only construction policy implemented in Sri Lanka. NPC, which contains 18 policies applicable to both public and private sectors, is found to be sufficient for the effective operation of the construction industry for the time being. However, the proper implementation of the policy could be a challenge given the nature of the country’s construction industry. The implementation of the policies gets interrupted when there are financial issues, insufficient human and technical resources, political influence, poor delegation of authority, and ineffective leadership. If the recommendations made in the study to overcome the barriers for policy implementation could be implemented, the country’s construction industry would develop rapidly.

Integrating enterprise resource planning system with lean concept to minimise waste in Sri Lankan construction industry – a theoritical review
(2019) Rasanjali, WA; Disaratna, V; Withanage, KT; Samarawicrama, S
Construction industry is currently facing severe challenge that producing high rate of waste at the end of the construction process. Lean philosophy has arrived and expanded over the various industries by providing an imperative solution for most of the challenges facing by the industries. Accordingly, construction industry accommodates lean concept to provide the modest output in the shortest possible time, while attaining maximum value and quality at reasonable cost. Enterprise Resource Planning (ERP) system is developed as an approach that integrates all business functions into a single process to enhance the efficiency of all activities by supporting organizations to uphold the competitiveness within the industry. ERP system affords accurate data of current performance in a single database with more transparency for the users who demands them. Construction companies used to adopt ERP system with the intention of enforce supply chain partnerships, enhance organizational flexibility, improve decision making capabilities and reduce project completion time and costs. The ERP system diminishes labour-intensive processes and eliminate the root causes for waste production in construction industry and already offers lean support in their software. This paper highlights the literature findings on the lean philosophy and synchronizes ERP system and lean principles in the course of lean ERP route. These basic findings will aid to assessing the possibility of integrating ERP system with lean principles in order to eliminate construction waste. Sri Lankan construction industry practitioners can directly use these findings of the research to eliminate the challenge of producing high rate of waste at the end of the construction process

Investigation of health and safety training requirements for large scale construction projects in Sri Lanka
(2023) Kumara, KRP; Disaratna, V
Construction industry is one of the most significant industries which makes a considerable contribution to the GDP. Currently a large number of employees are working in this industry and a number of fatal accidents taken place every year. Therefore construction is one of most hazardous industries in the country and more attention needs to be given to improve health and safety in this industry. Also, a lot of accidents taken place in construction projects are not reported. In the construction projects, enough competent safety professionals are not available to ensure the safe working environment. In Sri Lankan context people’s attitudes on health and safety is not in the satisfactory level and, to change the attitudes of the people a lot of improvements need to be made providing necessary training emphasizing the importance of the health and safety. This research focuses on the adequacy of health and safety training in large scale construction projects in Sri Lanka. The research followed a mixed method approach. A questionnaire survey and semi-structured interviews were used to gather the data. The questionnaire data was analyzed using statistical tools and manual content analysis was used to analyze interview data. The research revealed that training on health and safety conducted in large scale construction projects is not enough to meet the required level to maintain an accident free working environment. The different types of trainings such as first aid, work at height, fire, etc. are needed to be conducted to minimize the accidents generating in these projects. The research further revealed that to minimize this adverse environment, more attention needs to be paid and to do it successfully, enough budgets should be allocated.

(Istanbul Teknik Universitesi, 2022) Nisansala, MK; Shandraseharan, A; Perera, K; Disaratna, V
Errors in construction documents and records can have serious impacts on construction projects. These impacts are manifested mostly during the construction and post-construction stages of the projects. The errors in documents and records significantly affect the performance of quantity surveyors (QSs) working for contractors. Thus, the aim of this study was to investigate how the performance of contractor QSs could be managed using proper documents and records. A mixed approach was used to collect the required empirical data via a series of interviews and a questionnaire survey. The collected data were analysed using manual content analysis and relative important index, respectively. The results of the analysis indicate the documents and records that are significantly relevant to contractor QSs. Similarly, significant errors that can occur in those documents and records and causes of those errors also were identified. Finally, the solutions that could minimize the errors were identified and ranked according to their significance. The study findings revealed that the use of proper documentation and record management can enhance the performance of contractor QSs and ensure project success by controlling cost and time overruns.

Policy-level consideration on marginalised communities in the post-disaster context: A desk study
(Ceylon Institute of Builders - Sri Lanka, 2022-06-24) Mendis, APKD; Disaratna, V; Thayaparan, M; Kaluarachchi, Y; Sandanayake, YG; Waidyasekara, KGAS; Gunatilake, S
Natural disasters have a disproportionate influence on the lives of those impacted, with the most marginalised often bearing the brunt of the repercussions. As a result, marginalised communities should be expressly considered in post-disaster policy development. While the international community has adopted the concepts of resilience and inclusion, marginalised communities are frequently disregarded in post-disaster management. There is a dearth of literature on the engagement of marginalised communities in Sri Lanka's post-disaster context. Moreover, the policies to support the marginalised communities need to be reviewed to explore the extent to which such policies are implemented to benefit the disadvantaged groups in a disaster situation. Therefore, this paper aims to review the existing policies to improve the engagement of marginalised communities during the post-disaster context in Sri Lanka. To achieve the aim, a comprehensive desk study on significant global and national policies was carried out. Through the desk study, the policies and frameworks related to disaster management were explored in order to identify the inclusion of marginalised communities in the postdisaster context. The policies related to marginalised communities were further explored in order to identify the inclusion of them in post-disaster situations. Finally, the study confirmed that a refinement of the policies in the Sri Lankan context is crucial. Furthermore, as a way forward, the study suggested assessing the current level of implementation of existing policies as well as barriers to implementation in order to increase the inclusion of marginalised communities in Sri Lanka's post-disaster context.

Potential of implementing "window delay analysis" for road projects in Sri Lanka-claims consultants' perspectives
(2018) Maddumasooriya, GS; Disaratna, V
An increased number of disputes with regard to the additional times and payments in respect of the construction delay claims, are presently experienced by the road construction industry of Sri Lanka. The additional payment and time entitled to a claimant in respect of a delay, is generally computed utilizing an appropriate Delay Analysis Technique (DAT), the application and the outcome of which may vary from one another. Previous researchers have identified that the DAT namely “Window Delay Analysis Technique (WDAT)” was the most appropriate DAT that can be used for road construction projects in Sri Lanka, which was also the minimally used DAT out of several methods practiced in the country. Thus, the identification of the potential of implementing such highly recommended WDAT for road construction projects in Sri Lanka was of paramount importance, which was set as the aim of this study, which will also be towards the improvement of the practice of construction delay analysis in the country. In the view of above, the areas such as “benefits of WDAT”, “constraining factors for the implementation of WDAT”, and “studying the contemporary practice of delay analysis and willingness of the practitioners to undertake WDAT”, were explored as research objectives. A preliminary study carried out revealed that the awareness of construction community of the DATs was very low, which led the researcher to reach the Claims Consultants in Sri Lanka, who were supposed to be the most suitable resource persons on this subject area. Accordingly, this research problem was approached through the interviewing of four selected leading construction claims consultants in Sri Lanka, and by reviewing their eight sets of delay analysis documentations. WDAT was identified to be a versatile and practical approach of applying the delay analysis, rather than a primary method of delay analysis, which can be effectively applied in cases of complicated delay situations to resolve them successfully. The findings of this research revealed that the non-existence of a direct contractual requirement for its implementation, inherent limitations of applicability of the method, specific and compromised requirements of the claimants, the limited resources (budgets) of the claimant, the unawareness and the inexperience of the analysts, additional effort required on the part of the analyst, absence of prior preparedness and awareness, indirect discouragement of the analyst, and reluctance of the analyst to do his best, were the factors constraining the implementation of WDAT in Sri Lanka. The researcher ultimately realized that there is a potential for WDAT to be developed more as a separate area of expertise, which could co-exist as a support service to the general “construction claims consultancy services”.

(Ceylon Institute of Builders, 2016-07) Abiramy, S; Disaratna, V; Anuruddika, N; Sandanayake, YG; Karunasena, GI; Ramachandra, T
More than ever before, today’s global competition is driven by time. Many issues constituted problems for construction professionals, among them central issue is the time frame. Especially Quantity Surveyor’s day to day work involves management of activities and achievement of the short-term goals of the project. Therefore this study focuses on tactful time management for Quantity Surveying professionals practicing worldwide. Literature synthesis and preliminary survey were undertaken to establish the research problem of this study that emphasised lack of awareness and training among Quantity Surveyors on time management. Survey method was adopted whereby initially a preliminary survey was conducted among 10 Quantity Surveyors who are having vast experience in the field of study. Further questionnaires were distributed among 90 Quantity Surveyors and semi-structured interviews were conducted with 7 experts having specialised knowledge and experience in Quantity Surveying, Time management, Human Resource Management and Project Planning. The research findings acknowledged Quantity Surveyor’s roles and duties in a typical organization followed by critical activities that consume more time among the other duties such as preparation of final accounts and agreements and procurement and coordination of stakeholders etc. while dominant causes were lack of experience in Quantity Surveying practices and type and requirements of clients. The survey findings also offered possible techniques to maximise time management such as effective team work and Key Performance Indicators (KPIs) and identified barriers that could arise in implementing them. MANOVA test was carried out with the aid of SPSS tool, which verified the influence of type of sector, type of organisation, country of practise and managerial position employed on each factor. Further NVIVO software package was used to produce cognitive map to visualise the overall picture of study. Ultimately the solutions that emerged from the research findings were used to formulate guidelines to assist Quantity Surveyors achieving tactful time management in professional career - the aim of this research.

Sufficiency of the policies related to construction industry in Sri Lanka
(2020-11-06) Jayatunge, DASR; Mendis, APKD; Disaratna, V
Public policy on construction will reflect the economic, political, social, and cultural status of Sri Lanka. The construction industry in Sri Lanka has faced many issues in the recent past because of unsuccessful government policies. Therefore, an effective national policy for the construction industry has become necessary. Thus, the aim of this study was to examine the effectiveness of the existing construction policies. The empirical data required were collected by interviewing ten experts, who were selected using snowball sampling. The collected data were manually analysed using content analysis. The findings revealed that the National Policy on Construction (NPC), formulated by the National Advisory Council on Construction, which was set up under the Construction Industry Development Act No. 33 of 2014, is the only construction policy that has been formulated in Sri Lanka so far. NPC contains eighteen (18) policies applied for both the public and private sectors. Although according to the literature, policies in Sri Lanka change along with the change of governments, the study revealed that NPC, which has remained unchanged since its formulation in 2014, is still applicable in the country.

Tendency of Sri Lankan construction organisations in adopting enterprise resource planning systems
(Ceylon Institute of Builders, 2018-07) Silva, KGGDV; Disaratna, V; Dilakshan, R; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
The popularity of Enterprise Resource Planning (ERP) system is increasing in many industries. Many researchers have conducted studies on ERP in relation with construction industry as well. The observations of some of the researches were contradictory, while most of them are observing positive tendency among the contractors. Nevertheless, the tendency of Sri Lankan contracting organisations to implement ERP systems has not been studied. Hence, this research aimed to find the tendency of Sri Lankan contracting organisations to implement ERP systems. A mixed research approach along with an extensive literature review has been carried out to pursue the aim of this research. The concept of ERP has been identified along with the driving and restraining factors in implementing ERP system to contracting organisations. It has been identified that ERP system is popular among the Sri Lankan construction industry professionals since most of them at least heard about the system. Nevertheless, as per the conclusion, even though there is a positive tendency among global contractors to implement ERP system to their organisations, Sri Lankan contracting organisations are still lacking in confidence to implement the system.
