Item APPRAISAL OF APPLICATION OF VALUE ENGINEERING METHODOLOGY IN MECHANICAL AND ELECTRICAL SERVICES INSTALLATIONS(Penerbit UTM Press., 2015) Amuda Yusuf, Ganiyu; Sanni, Afeez O.; Olowa, Theophilus O.O.Value engineering (VE) is a structured team-oriented problem solving approach that can be applied throughout the lifecycle of a building project. However, the methodology is rarely applied in mechanical and electrical services (M&E) installations in buildings because clients are not aware of the potential benefits of adopting VE and different members of design team lack the requisite knowledge about VE methodology. As a result, a great deal of unnecessary cost is created due to the increasingly complex nature of M&E services in buildings leading to cost overruns and unhappy clients. The purpose of this study is to investigate the level of adoption of VE methodology in the design and installations of M&E services in buildings in Malaysian construction industry. The research method adopted is questionnaire survey to industry practitioners and inferential statistics was adopted for data analysis. Findings from the study show that, VE is not well appreciated in the industry and there is no structured approach adopted for its adoption for the procurement of mechanical and electrical services. Practitioners are of the opinion that implementation of VE could lead to: significant capital and life cycle cost savings in buildings generally; alignment of stakeholders and construction process improvement; improved client satisfaction, and shared understanding among key participants. An implementation framework was developed which emphasised on the need for early involvement of consultants and collaboration between the downstream supply chain for effective implementation of VE methodology on mechanical and electrical services.Item Barriers to Building Information Modelling Adoption in Nigeria(Department of Civil Engineering, University of Ilorin, 2017) Amuda Yusuf, Ganiyu; R.T., Adebiyi; T.O.O., Olowa; I.B., OladapoBuilding Information Modeling (BIM) adoption is still evolving in Nigeria and there are no many examples of its usage for project execution by industry practitioners. There is a dearth of studies on how barriers to BIM adoption can be overcome. Following the identification of barriers to BIM adoption from literature, an online survey approach was used to investigate the perception of Nigerian construction industry professionals on the significant barriers to BIM adoption based on a five point Likert scale from 1 “not at all a barrier” to 5 “extreme barriers”. Class means difference among professional group was used to identify barriers to BIM adoption and a discriminant analysis was used to established disagreement among the respondents. The result shows that, the various groups have equal mean discriminant function score on 16 barrier factors to BIM adoption, indicating agreement in the opinion of the groups on these factors. However, 5 items have the most significant predictive power in differentiating the professional groups from the standpoint of perceived barriers to BIM adoption. Implying that there is difference of opinion between the group on whether the 5 factors constitute barriers to BIM adoption or not. The factors in order of magnitude are: clients low level of awareness, lack of funding, poor power supply, legal uncertainty and lack of transparency. The barrier factors identified in this study will assist industry stakeholders in formulating appropriate strategies to overcome them in order to ensure successful BIM implementation. Findings from this study indicates the need for construction industry stakeholders to encourage practitioners to adopt BIM at various level for project execution.Item BIM Awareness and Adoption by Construction Organizations in Nigerian(Faculty of Engineering, University of Ilorin, 2018) Amuda Yusuf, Ganiyu; Adebiyi, R.T; Isa, Bala MuhammadBuilding Information Modeling (BIM) processes is gaining ground in the construction industry especially in the developed countries. Similarly, the professionals in developing economies such as Nigeria are expected to braise themselves with the current trend knowledge acquisition such as BIM. To ensure adequate planning for the construction industry adoption of BIM by professionals in Nigeria, it is important to determine the current level of awareness and adoption of BIM in the industry. Questionnaire survey was administered to construction industry practitioners to elicit information about their level of awareness and application of BIM. Descriptive analysis was used to analyze data collected from the survey. It has been established that the size of organization has effect on the transmission of information and knowledge from one level to another. As such the variables used in the analysis are the size of organizations‟, organizations turnover and industry professionals. Results of data analysis shows that the traditional Design-Bid-Build approach is still the most common approach and significant differences exist in the level of BIM utilization for projects among the professional group. Similarly, the design information exchange format utilized by various organizations varied based on the size and turnover of organizations. On the level of awareness and understanding of BIM, the results shows that the size of organisations influences level of awareness and understanding of BIM among respondents.Item BIM INTEROPERABILITY AND INFORMATION STANDARDISATION(Nigerian Institute of Quantity Surveyors, 2018) Amuda Yusuf, GaniyuItem Critical Success Factors for Building Information Modelling Implementation(UTS ePRESS, 2018) Amuda Yusuf, GaniyuThis paper expounds the Critical Success Factors (CSFs) for BIM implementation and explore their ranking and underlying relationships. A total of 28 CSFs was identified from the review of previous studies on success factors. Survey questionnaire containing these 28 factors was used to collect data from industry practitioners in Nigeria. Benchmark metrics was developed to rank the success factors. The topmost five success factors for BIM implementation in order of importance are: standard platforms for integration and communication; cost of development; education and training; standardization (product and process); and clear definition and understanding of users’ requirement. Analysis of variance shows that significant differences exist in the pattern of rating for the topmost CSFs based on turnover. Factor analysis was further adopted to group the 28 CSFs into five components, using rotated component matrix method. The five components extracted are: (i) industry stakeholders’ commitment and knowledge of BIM, (ii) capacity building for technology adoption, (iii) organisational support, (iv) collaborative synergy among industry professional and (v) cultural orientation. The rankings of the CSFs have practical implication as it provides basis for refining the most significant factors that industry stakeholders should focus attention for successful implementation of BIM. In addition, the underlying relationships among the success factors identified in this study, will assist industry stakeholders to determine best strategy to adopt in implementing BIM at industry level.Item EFFECTS OF ENVIRONMENTAL FACTORS ON CONSTRUCTION PROJECTS TIME AND COST PERFORMANCE(Journal of Environmental Spectrum, 2015) Amuda Yusuf, Ganiyu; ADEBIYI, R. T.; BABALOLA, M. OThe delivery time and cost of a construction project is a key factor and source of concern to project stakeholders in the Nigerian construction industry. It is apparent that environmental factors are a major contributor to construction time and cost overruns. This study examines the influence of environmental factors on construction time and cost performance in Lagos state. A total of two hundred and forty-one (241) copies of questionnaire were administered on industry practitioners through convenience and snowballing sampling. A total of twenty-six (26) environmental factors were identified and grouped under six categories. The magnitude of the mean scores of each item was adopted to rank them in order of importance. The results of the study revealed that cost of government policy is the most significant factors affecting time overrun with a mean score of 4.7552 followed by project team commitment with a mean score of 4.4772. Similarly, instability in government and importation of materials and equipment are considered as the most significant factors affecting cost overruns. However, the significant factors identified from this study can be used as parameters for developing strategy for reducing the impact of environmental factors on on construction time and costItem Essential features of a building services standard method of measurement in Malaysia(Emerald Insight, 2015) Amuda Yusuf, Ganiyu; Sarajul, Fikri MohamedPurpose – The purpose of this paper is to examine the need to develop building service standard method of measurement (BSSMM) that would provide a home ground advantage and a framework for managing the cost of building services by quantity surveyors. Design/methodology/approach – A review of previous research on the rules of measurement was carried out. This exercise provides the basis for questionnaire design which was administered to quantity surveyors in Malaysia construction industry. Findings – The results indicated the need to develop BSSMM. In total, 23 variables were identified as essential features of such standard method of measurement. These variables were grouped into three categories and a priority ranking of them was carried out. The analysis revealed a strong agreement among quantity surveyors on the priority ranking of the essential features of the BSSMM. Research limitations/implications – Although, the research would assist industry stakeholders in developing BSSMM that reflects local and international best practices, there is need to further investigate how the rules of the BSSMM could be aligned with construction industry classification systems. Practical implications – The availability of information and computer technology (ICT) tools has transformed the traditional practices in the industry and offered values to quantity surveyors, but if quantity surveyors’ tools cannot be consolidated and incorporated into emerging ICT applications, then QS collaboration will be difficult, and the requirements for electronic data exchange will be impractical. Therefore, this type of standard method of measurement will facilitate cross-referencing and coordination between BoQ and other documents such as drawings, specifications and tender produced by other project participants and thereby lay efficient foundation for effective collaboration of quantity surveyors in BIM model. In addition, the BSSMM will not only comply with local industry practices, it will also be internationally compatible. Originality/value – Adoption of a structured format based on BSSMM to present building services cost information is essential in view of the increase in the value and complexity of building services in modern buildings. However, there is need to enhance quantity surveyors’ knowledge in the technology and cost management of building services so as to ensure the reliability of cost advice provided to clients. This goal would be partly achieved through education and training of Quantity Surveyors/Cost Consultants in the interpretation and use of the rules of an SMM.Item Evaluation of Risk Factors Impacting Cost and Time Performance of Mechanical and Electrical Services Installation in North Central Nigeria(Faculty of Environmental Design and Management, 2017) Amuda Yusuf, Ganiyu; Ranti, Taibat ADEBIYI; Theophilus Oluwarotimi, Olatunde OLOWA; Ibrahim, Babatunde OLADAPO; Lukman, Olarewaju OLORUNOJE; Soliu, IDRISMechanical and Electrical (M&E) services project are complex in nature and a number of risk arises at the design and installation stages resulting into poor cost and time performance. This paper identified and ranked the risk factors affecting cost and time performance of M&E services projects. Thirty risk factors identified from preliminary investigations were adopted as basis for a questionnaire survey to architects, engineers, quantity surveyors and project managers in North Central Nigeria. Initial statistical analysis produced 23 risks factors that would affect cost and time performance of M&E services projects and analysis of variance results show that no significant difference exists among the opinions of the professionals surveyed on the 7 risk factors. Factor analysis was adopted to classify the risk factors into five principal components namely, pre-contract risks, post contract risks, clients' related risks, procurement and external risks. The risk identification and ranking are good tools for assessment of risks related to M&E services projects. In addition, the classification of the risk factors can be used to establish important risk factors that require the attention of project participants. This will allow the client and contractor to understand the high-risk areas in M&E services projects and assign responsibility for those risks to the party or parties best situated to control them.Item FACTORS CONTRIBUTING TO NON-ADOPTION OF VALUE ENGINEERING METHODOLOGY FOR BUILDING SERVICES(Penerbit UTM Press, 2015) Amuda Yusuf, Ganiyu; Adebiyi, R. Taibat; Oyewumi, A. DamolaThe procurement of building services (BS) constitutes a great challenge in the construction industries of both developed and developing countries. Adoption of value engineering (VE) methodology could aid BS components selection at design and installations stages. However, the methodology is not appropriately used by the project team during design and installation of BS. Leading to overdesign, poor quality specification, lack of team work and unreliable budget estimate. The main objective of this paper is to determine the factors preventing the adoption of VE in the procurement of BS projects. A questionnaire was design to collect information on 18 generic factors contributing to non-adoption of VE. The questionnaire was administered to randomly selected practitioners in clients’, contracting and consulting types of organisations in Malaysia. The result shows that lack of understanding of VE by clients organisations, lack of request for the services, and inadequate time to conduct the study are the most important factors deterring adoption of VE for building services. The factors analysis of result for the 18 variables produced a four (4) factors result as: Non-involvement of stakeholders; education and traditional practice; resistance to change, and lack of experience about VE. It is essentially important for industry clients to understand the importance of adopting VE so as to ensure that time required for the study are pre-planned and budgeted for at project inceptionItem Factors Inhibiting the Adoption of a Uniform Pricing Mechanism for Building Services(intechopen.com, 2013) Amuda Yusuf, Ganiyu; Sarajul, Fikri Mohamed; Suhaila, Binti RemeliThis study describes an empirical investigation revealing the critical obstacles to the adoption of a uniform pricing mechanism for building services from the perspective of industry practitioners . A total of 157 questionnaires conducted on quantity surveyors (N=75), mechanical engineers (N=39) and electrical engineers (N=43) were collected and used for the study. T –test statistics was run to identify ten significant factors from a list of fourteen factors identified. Relative importance indices were computed for each factor from the perspectives of the practitioners so as to determine the most critical obstructive factors. The result shows that the five most important obstructive factors in order of significance are: (1) difficulty in the interpretation of the Standard Method of Measurement by design consultants (2) the late involvement of building services design consultants (3) quantity surveyors’ insufficient skill in mechanical and electrical services technology (4) drawings of services are often not ready for billing at the tender stage and (5) the lack of a generally accepted Standard Method of Measurement for mechanical and electrical services.Item IMPERATIVES OF ALIGNING MEASUREMENT STANDARD WITH INFORMATION CLASSIFICATION SYSTEMS(The Department of Architecture, Ahmadu Bello University Zaria-Nigera, 2016) Amuda Yusuf, Ganiyu; Taibat, Ranti Adebiyi; Ibrahim, Babatunde Oladapo; Soliu, IdrisThe automation of Quantity Surveyors (QS) traditional quantity extraction and estimating process is practicable in Building Information Modelling (BIM). However, the existing measurement standards used by Nigerian Quantity Surveyors (NQS) will not facilitate electronic information exchange among project team because it is not aligned with any local industry classification systems. This paper examined the need for the measurement standard used in Nigeria to follow local information classification system which could enable it coordinate with other local product information and naming conventions. The research method adopted is literature synthesis, cross-country comparison and analysis of the classification systems that were adopted as basis for developing measurement standards in selected countries. This was followed by open ended interviews to experienced QS working in clients, contracting and consulting organisations. Content analysis was used to analyse the interview questions. The study reveals that different countries adopted different classification approaches based on their country specific classification systems in developing their local measurement standards, which in turn aids electronic information coordination among project participants. It was also found that, NQS can develop a measurement standard that could provide basis for the development of local information classification systems. Such standards will promote electronic information exchange among practitioners, facilitate speedy comparative evaluation of alternative design solution; assist in ICT adoption by QS, promote the use of e-procurement of construction project, reduce pre¬construction documentation period, promote transparency in tender evaluation and promote QS ability to work with other project team members. The research suggests that the construction industry practitioners should collaborate and establish an industry-wide information classification systems that could provide basis for a common ICT platform for project team. Such standard should then form basis for measurement standard development by QS and specification documents by architect and engineers.Item AN INVESTIGATION INTO THE DESIRED ATTRIBUTES OF BUILDING SERVICES STANDARD METHOD OF MEASUREMENT IN MALAYSIA(University of Lagos, Akoka, Yaba, Lagos & Heriot-Watt University, Edinburgh, UK, 2014) Amuda Yusuf, GaniyuThe continuous increase in the value and complexity of building services has called for the need to present building services cost information in a structured format. There is therefore, a need to develop building services standard method of measurement (BSSMM) and determine the desired attributes in the context of the Malaysian construction industry. These attributes of a standard method of measurement were identified through secondary sources including cross –country comparison of existing standard method of measurement. A Stratified sampling approach was adopted to administer 400 questionnaires to the quantity surveyors in client contracting, and consulting organisations in the Malaysian construction industry These attributes were categorised into three and the results of questionnaire survey was adopted in ranking the variables. The survey result showed that, there is a need to adopt a standard method of measurement for building services. Further, there was agreement among quantity surveyors on the priority ranking of the desired attributes of the standard method of measurement for building services. However, for the standard to be acceptable, it must align with Construction Industry Classification Systems so as to lay an efficient foundation for automation of the estimating process.Item Perceived Benefits of Adopting Standard – Based Pricing Mechanism for Mechanical and Electrical Services Installations(JACEP, 2014) Amuda Yusuf, Ganiyu; Sarajul Fikri, MohamedCost is an important measure of project success and clients will expect a reliable forecast at the early stage of construction projects to inform their business decision. This study was undertaken to investigate the current practices in managing cost of mechanical and electrical (M&E) services in buildings. The perceptions of practitioners on the benefits of adopting Standard – Based Pricing Mechanism for M&E services as used for building fabrics and finishes was ascertained. The methodology adopted for the study was semi – structure interview and questionnaire survey. Inferential statistics technique was used to analyse the data collected. The results revealed that, M&E services tender documents are often based on lump sum contract. Practitioners are of the opinion that the adoption of Standard – Based Pricing Mechanism (SBPM) could enhance the quality of M&E services price forecasts; ensure active post contract cost monitoring and control; encourage collaborative working relationship; enhance efficient whole life cycle cost management; improve risk management and facilitate an efficient tendering process. The study suggested the development of local Standard Method of Measurement for M&E services and proposed strategies to facilitate the adoption of SBPM as basis for forecasting contract price of mechanical and electrical services in buildings.Item PERSPECTIVES ON COST MANAGEMENT ROLES OF QUANTITY SURVEYORS' IN MECHANICAL AND ELECTRICAL SERVICES PROJECTS(Centre for Human Settlements and Urban Development, Federal University of Technology, Minna, 2016) Amuda Yusuf, Ganiyu; ADEBIYI, R. T.; Olowa, T.O.O.Mechanical and Electrical Services (M&E) is a complex system of buildings and their values constitutes a significant component of construction costs. The procurement is commonly based on lump sum and performance specification and there is lack of reliable cost information regarding elements of M&E services to guide project participants at the inception of building projects leading to inaccurate budget estimate, disputes, time and cost overruns. This study examined the cost management roles and functions performed by Quantity Surveyors (QS) on M&E services projects. The study was carried out using data from questionnaire survey to QS and services engineers in the North-Central geopolitical zone of Nigeria. Data analysis was carried out using t-test of the means to check the significance of the responses to the issues raised in the questionnaire. The results showed that the pre-contract cost management roles performed by QS is limited to the use of single purpose approximate estimating method, statistical method and historical cost information to advice clients' on M&E services project at this stage. At post-contract stage, QS prepare interim valuation, assessment of variations, claims and final account preparation. Quantity Surveyors missed the gap to effectively manage the cost of M&E services project, instead, single price approximate estimating methods based on historical cost information and statistical approach to establish indicative cost of M&E services project. Making it difficult for QS to offer reliable cost advice for comparative design solutions of alternative M&E components and installation. With the increase in the value and complexity of Mechanical & Electrical Services projects, industry clients should engage quantity surveyors to perform the full spectrum of their cost management functions on element of M&E services project. Quantity surveyors should also collaborate effectively with services engineers from the inception of M&E services project to enable them gain full understanding of the technology of M&E services components.Item Quantity Surveying Practice and Evolution of SD Building Information Modelling(College of Engineering and Environmental Studies, 2016) Adebiyi, R.T; Babalola, M.O.; Amuda Yusuf, GaniyuManual quantification by Quantity Surveyors (QS) from two dimensional drawings is complex and prone to human error because of technological and organizational problems. Building Information Modelling (BIM) is an emerging technology with potentials for automation of quantity take-off and estimating process. This study examines barriers to five dimensional (5D) BIM adoption by Nigerian QS. Purposive sampling approach was used to administer questionnaire to practitioners in construction, consulting and clients' organizations in Nigeria. A total of 53 validly completed questionnaire were returned and analyzed using Statistical Package for Social Sciences. The five most important barrier factors to 5D BIM adoption by QS are: lack of collaborative initiatives from industry stakeholders; problems of communication and data sharing among firms; lack of government support and clear roadmap for BIM implementation; BIM model is not compatible with traditional take-over estimating software tools; and non-alignment of current rules of Building and Engineering Standard Method of Measurement. The 5-dimensiona/ BIM have tremendous potentials to increase the communication efficiency and interpretation ability of quantity surveyors. However, there is need for construction industry stakeholders to formulate strategies to develop and implement information exchange system that can support collaboration.Item RISK FACTORS IMPACTING COST AND TIME PERFORMANCE OF MECHANICAL AND ELECTRICAL SERVICES PROJECTS(Faculty of Environmental Design and Management, 2017) Amuda Yusuf, Ganiyu; Adebiyi, Ranti Taibat; Olowa, Theophilus O.O.; Olorunoje, Lukeman O.; Idris, SoliuMechanical and electrical (M&E) services project is complex in nature and involves a large number of specialist organisations entering the project life cycle at different stages with different lines of relationships, responsibilities and risk management capabilities. Hence, a number of risk arises at the design and installation stages which results into poor cost and time performance in M&E services projects. This paper identified and rank the risk factors affecting cost and time performance of M&E services project. A total of 30 risk factors identified from preliminary investigations was adopted as basis for a questionnaire survey to industry practitioners in Nigeria. Mean response analysis was used to determined the probability and severity of the risk factors and risk impact scores was used to rank the relative importance of the risk factors. Analysis of variance (ANOVA) was used to investigate differences of opinions between respondents'. The study identified 23 risk factors (risk impact >3.5) impacting M&E service projects. Out of these risk factors, 7 has significant impact while the rest have moderate impact. The 7 risk factors in order of their significance are: high foreign materials content, poorly prepared tender document, late involvement of M&E engineers, non-involvement of specialist designers, government policy change, poor specification and poor coodination of design imputs. In addition, ANOV A results show that no significant difference exists among the professionals on these 7 risk factors. This suggests that the risk level of M&E services project is high. The identification and ranking of the risk factors has practical implication in M&E services project. The risk identification and ranking table is a good tool for assessment of risks related to M&E services at project inception. This will allow the client and contractor to understand the high risk areas in M&E services project and, where applicable, assign responsibility for those risks to the party or parties best situated to control them.Item Role of Building Services Quantity Surveyors in Managing Cost of Green Buildings(Advanced Materials Research, 2013) Amuda Yusuf, Ganiyu; Sarajul, Fikri Mohamed; Zakaria, Mohd Yusof; Mohd, Saidin MisnanThis study reviews the importance of green building and identified some popular rating tools available. The importance of green building requirements was also discussed. Significant cost factors in green buildings were described and methods of capturing and controlling the costs of building services by quantity surveyors discussed. The major barrier to effective cost control of green building have been identified as lack of a clear green design goal; midstream attempts to incorporate green; decentralized management of the green building process; lack of experience with green building; and insufficient time and funding. The study concluded that, it is essential for quantity surveyors to develop a cost management framework responsive to both client values and user requirements within the framework of sustainable development.Item Standard for uniformity in building engineering services price forecast(Taylor & francis Group, London, 2014) Amuda Yusuf, Ganiyu; S.F., MohamedEstablishment and implementation of a standard method of measurement for building engineering services can significantly improve the reliability of project cost estimates and cost control of the entire building project. Current practices in the formulation of building engineering services contract price, was determined and the factors that influenced the current practices established. The provisions of the current standard method of measurement in use in Malaysia were examined in relation to current building engineering services procurement and cost management. A total of 47 tender documents was reviewed in Southern Peninsular Malaysia. The research has allowed conclusion to be drawn as follows: there is no uniformity in the tender documents prepared by various consultants for the procurement of building engineering services. Standard method of measurement could be used as a basis for forecasting price of building services. Factors that influenced its non adoption include inadequate design information on building services and slow learning curve by practitioners.Item Towards developing Building Services Standard Method of Measurement in Malaysia(Taylor & francis Group, London, 2014) Amuda Yusuf, Ganiyu; Mohamed, S.F.; Yusof, Z.M.; Misnam M.S.Detail quantification and description of items of works based on standard method of measurement (SMM) are not adapted for building services precontract price forecasting by Quantity Surveyors (QS). However, with increasing value of building services in modem buildings, there is need for QS to manage its cost. The variables that prevent quantity surveyors from measuring building services in line with the provisions of an SMM were identified. It was also found that an SMM aligned with local information classification system is important to lay foundation for integration of SMM into model based automated quantity extraction and estimating. The method adopted for the study is literature review and synthesis as well as cross-country comparsion of existing SMMs. A conceptual framework was developed to guide industry stakeholders in developing building services standard method of measurement (BSSMM).
