  • Time Overrun Causes in Public Construction Projects in Saudi Arabia:
           Contractors’ View
    • Authors: Ibrahim Mahamid, Nabil Damidi
      Abstract: The time schedule in construction projects is one of the prime measures for project success. However, the construction industry worldwide is full of projects that were completed with significant time overrun. This problem is critical and has negative effects on construction parties in terms of growth in adversarial relationships, mistrust, litigation, arbitration and cash flow problems. This study aims at identifying the time overrun causes in public construction projects in Saudi Arabia from contractors’ viewpoint. To do so, 62 contractors from Northern Province of Saudi Arabia who are working on public construction completed a structured questionnaire survey. 35 time overrun causes were identified through literature review. The results indicated that the top affecting causes are: additional work, bid award for lowest price, changes in material types and specifications during construction, contract management, fluctuation of prices of materials, improper planning, inflationary pressure, lack of contractor experience, poor labor productivity, and rework.

  • An Empirical Study Summary on Integrated Building Commissioning for New US
           Federal Domestic Construction Projects
    • Authors: Bennett Varghese
      Abstract: Current management practices for federal domestic construction projects need to be modified to mitigate the negative effects newly constructed buildings have during the first few years of occupation. These negative effects include poor indoor air quality and poor performance of its tenants during the initial years of building occupancy. This empirical study focuses on the staff of the US Mission to the United Nations (USUN) as an off-site temporary facility was built for them in 2004 followed by a permanent office building in 2010. The newly constructed temporary facility exhibited indoor air quality deficiencies and the performance levels of USUN staff were also diminished during the initial years of occupancy. For the construction of the permanent building, the United States Department of State decided to employ a new project management practice of integrated building commissioning. Integrated building commissioning is the systematic, documented and collaborative process including inspection, testing and training conducted to confirm that a building and its component systems meet the requirement of the occupants and conform to the design intent. It involves the special expertise of the client government offices throughout the entire construction process by thoroughly integrating them within the networked process of a major construction project. The permanent USUN building yielded results that showed acceptable levels of satisfaction with the indoor air quality immediately after occupation and the performance levels of the USUN staff also increased comparatively in the initial years after occupation.

  • Re-engineering the Engineered Construction Organization
    • Authors: R. K. Pandit
      Abstract: The concept of organization as a basic information processing system to provide flexibility and adaptability in highly uncertain and turbulent construction environment was used to design a post-bureaucratic organizational structure particularly for construction industry. The different divisions/departments in the organization are developed as interacting information processing subunits generating and disseminating a continuous flow of data/information. In addition to proposing the efficient way of vertical communication for productivity improvement, the proposed model lays major emphasis on lateral information flow. Hence the coordination in the organization is the basis of reengineering it.

  • Influence of Recycled Coarse Aggregate on Properties of Concrete
    • Authors: O. J. Ameh, U. E. Edike
      Abstract: This study focuses on the influence of recycled coarse aggregate (RCA) on properties of concrete. Five different mixtures of RCA replacement comprising 0, 25, 50, 75 and 100% RCA were used. It was found that workability, saturated bulk density, compressive strength and flexural strength decreases with increase in RCA content in concrete. 100% manually RCA concrete passed the 17 kN/m2 compressive strength limit generally acceptable for concrete work of non-high strength requirement without additive. The research, therefore, recommends the use of recycled coarse aggregate concrete for residential and light commercial building projects bearing in mind that low-strength concrete is only appropriate for mild environmental exposures, and interior concrete protected from the elements. This development in recycled concrete technology would help to alleviate our losses through efficient reuse of recovered coarse aggregate from demolished buildings and infrastructure; hence, reducing waste and dung creation and thereby enhancing adequate environmental management.

  • Experimental Investigation of Mechanical Properties of Hybrid Fiber
           (Basalt and Steel) Reinforced Concrete
    • Authors: R. L. Shirale, Remya Muralidharan, Rupali Shinde
      Abstract: The paper reports experimental investigations on hybrid-reinforced concrete. The proportion of basalt fiber and steel fiber was 50% respectively of the total fiber taken as sample. Effect of fiber on various strengths of concrete is studied. Fiber content varied from 0 to 4% at an interval of 1% by weight of cement. Various considerations for investigation are compressive strength, flexural strength, split tensile and bond strength. Cube of size 150 × 150 × 150 mm for compressive strength, beams of size 500 × 100 × 100 mm for flexural strength, cube of size 100 × 100 × 100 mm, cylinder of 100 mm (Diameter) × 300 mm (height) were casted. All the specimens were cured for 7 and 28 days and tested subsequently. The workability is measured with the slump-cone test. The wet and dry density at 7 and 28 days is calculated. Relation between compressive strength and all other strengths is developed. A comparison of results of hybrid fiber-reinforced concrete with that of normal concrete showed significant improvements in the results of various strengths.

  • Adopting Appropriate Gradation in Design of Bituminous Concrete Mixes at
           
    • Authors: Mohamed Ilyas Anjum
      Abstract:   The MoRTH in India specifies gradation tables for preparing bituminous mixes with desirable range of aggregates passing for each aggregate fraction. Conventionally, the mix is designed by adopting midpoint of the specified range of aggregates passing, anticipating a satisfactory mix and avoid several trials required to arrive at the best gradation within the specified range.  In this approach, the aggregate shape factors expressed as combined index being the sum of flaky and elongation indices of aggregates in the mix, are determined using conventional instruments. The limitation is that the slot sizes available on instruments are not the same as the sieve sizes in gradation tables. In spite of this, the shape factors determined are still assumed to be approximately the same as those for the actual aggregates sizes, example available is 25–20 mm while size required is 26.5–19 mm. As such, an attempt was made to determine the shape factors for the actual aggregates sizes and ascertain if the midpoint gradation approach is still valid. Bituminous concrete mixes were prepared corresponding to the midpoint (MG) as well as the lower (LG) and higher (HG) limits besides the mid points of lower – mid point (LMG) and higher - mid point (HMG) gradations by using same aggregates. All the other materials and their properties were maintained uniform. The Marshall Test properties of bituminous concrete mix–grade 1, at these five gradations were compared. It was noted that the conventional midpoint gradation does not produce the most satisfactory mix.

  • Risks in Construction Industry of Mangalore
    • Authors: Rohan Maxwel Colaco, M.K. Nagaraj, T.P.M. Pakkala
      Abstract: The study of risks in construction industry is an open-ended experiment as not many references are available for comparison. The geographical divide of India poses a challenge to the construction fraternity due to varied factors of risks involved in construction activities and it is not possible to give a common risk matrix for construction projects in India. It invariably has to be divided into smaller segments and the geographical area has to be selected based on similarities in conditions. Nevertheless, when the study of a particular region is completed the model can be replicated in other regions to get the risks associated with construction activities in that particular region. Also the construction activity varies with type of projects, viz., public, private and public-private partnership projects. In the present study, the construction activity in Mangalore city is taken as the pilot sample. The private residential projects, viz., apartments, houses and commercial complexes are taken as the group under study. The risk associated with the above construction activity is obtained through a questionnaire survey and the outcome is studied.

  • Empirical Evaluation of Performance of Construction Management at-Risk (CM
           at-Risk) Project Delivery System With and Without Agency-CM
    • Authors: Abdul Khader Jeelani Shaik, Dr. Adel S. Al-Dosary, Dr. J. Karthikeyan
      Abstract: A project delivery system is a comprehensive process of assigning the contractual responsibilities for designing and constructing a project. Design-Bid-Build (D-B-B), Design-Build (D-B), and Construction Management at risk (CM-at-Risk) are the three principal project delivery systems. Agency CM is as a construction management system, and is a way to manage the process of construction. Agency-CM doesn’t take any performance risk in guaranteeing project cost, project schedule and project quality. Generally Agency CM is remunerated on monthly fee, lump sum fee or by the percentage of the project cost that has conflict of interest with the final project schedule and final project cost. Considerable amount of fee is paid to the Agency CM in order to improve the efficiency of the project. This necessitates a comprehensive investigation in to the performance of projects delivered with Agency CM and projects delivered without Agency CM. Agency-CM can be used with any type of Project Delivery system. This study is intended to evaluate the project performance metrics such as Project Cost, Project Schedule and Project Quality in Projects where CM –at - Risk Project Delivery System was used with Agency CM and Projects and where CM-at-Risk Project Delivery System was used without Agency CM. The study included literature review, designing a questionnaire, collecting data from 200 CM-at-Risk projects of which 100 projects where Agency CM was used and 100 projects where Agency CM was not used. Analysis of data pertaining to project performance metrics was done by using Statistical Product and Service Solutions (SPSS) statistical software. An understanding of this study may help an owner/client better select the most suitable Project Delivery System between the CM-at-Risk Project Delivery System with Agency CM and CM-at-Risk Project Delivery system without Agency CM.

  • A Comparative Study on Causes of Delay Incompletion of Construction
           Projects in Oman
    • Authors: Mohammed A. Chasib Al Mohsin, Ali Alnuaimi
      Abstract: The aim of this paper was to identify the problems resulting from the delays in completion of construction projects in Oman. A field study was conducted on a number of construction projects in Muscat area to collect data required for analysis. Two groups of projects were studied, the first group included projects constructed during the period 2007–2008 and the second group studied comprised projects constructed during the period 2009–2010. It was found that 40 per cent of the projects constructed during the periods of both groups have experienced delays in completion with slight differences in the length of delay between the two groups. Another finding was that the causes of delay are changing with the time in a pattern depending on different variables. Owner related causes were found to be the dominant reason for delay and contrarily the first to seek solutions.

  • Experimental Study on Fibre Reinforced High Performance Concrete with
           Silica Fume
    • Authors: Durai S, Boobalan S C, P. Muthupriya, R. Venkatasubramani
      Abstract: This paper presents the effect of silica fume and glass fibre in High Performance Concrete (HPC). In this study, High Performance Concrete mixes with silica fume of 0, 10, and 20% with addition of glass fibre of diameter 14 μ and 12 mm length at various percentages as 0, 0.3, and 0.6% by the volume of cement on M75 grade of concrete. The mix proportions of concrete had a constant binder of 0.26 and superplasticizer was added based on the required degree of workability. For each mix standard sizes of cubes, cylinders and prisms as per Indian Standards were cast and tested for compressive strength, split tensile strength and flexural strength at the age of 28 days. The addition of silica fume shows early strength gaining property and that of glass fibre control the cracking due to shrinkage. The results are satisfactory for the use of 10% silica fume and 0.3% glass fibre in producing High Performance concrete.

  • Diagnosis and Repair of Deteriorated Concrete Structures
    • Authors: Sanjay Gupta
      Abstract:  In India, we come across many old buildings needing major repairs or go early in to a state of dilapidation condition to make them unfit for occupation. The premature deterioration of structure is an economic burden not only on owners but also to the municipalities’ and nation as a whole. The longer life of structures enables better utilization of natural resources. Reduction in waste due to demolition enhances energy conservation. Such philosophy will be in harmony with the environment and help in achieving sustainability of system. It would also lead to benchmark standards of maintenance and upkeep of buildings. Of course, the buildings/structures should also be appropriately designed for resistance to natural disasters like earthquakes, cyclones, floods etc. This premature deterioration is largely due to poor construction or inappropriate design and/or neglect of timely repairs. Proper understanding of the probable causes of poor performance or faster deterioration of buildings especially concrete structures which constitutes a major part of the structures constructed till date is essential, so that precautionary measures can be taken by the designers, constructors, consultants and the owners. The details of the process, steps and the common methodology in the diagnosis and repair of deteriorated concrete structures are given here.

  • Influence of Mineral Admixture on Compressive Strength of Concrete
    • Authors: K.S. Radhika, K. Baskar
      Abstract: The current paper shows the results of an investigation focused on the effect of metakaoline (MK) and silica fume (SF) on the compressive strength of concrete. The aim of the study was to investigate the effect of concrete compressive strength containing different percentage levels of metakaoline and silica fume on fresh and mechanical properties of the concrete. Pastes containing 0%, 5%, 10%, 15% and 20% of metakaoline and silica fume concrete were prepared at constant water-cement ratio of 0.4 and cured in indoor climate of laboratory condition for hydration periods from 1 to 28 days. The work focused on concrete mixes having a fixed water-cement ratio of 0.4 and variable cement content for replacement levels. The results of this research indicate that as the proportion of metakaoline and silica fume increased, the workability of concrete decreased but the compressive strength of concrete containing silica fume and metakaoline was not reduced than the control concrete.

  • The Development of the Quality Assurance Approach in the Building
           Construction Industry; the Malaysian Context
    • Authors: Kenn Jhun Kam, Ahmad Hilmy Abdul Hamid
      Abstract: This paper reviews the quality assurance approach which may have a huge potential impact in Malaysia’s construction industry. Rather than the price of the product alone, it has been stated by many previous researchers that a better product quality will serve as an advantage in sustaining the competition that emerges in the construction market. Recently, quality has been identified as one of the basic requirements that the clients tend to look for. Buyers are becoming more educated and their expectation on high-quality products is increasing. The preference for product quality as one of the clients’ aspect of concern in completed buildings can be classified as one of the biggest investments of assets in their entire lives, for most clients. This phenomenon results in the Malaysian government introducing a quality system model – the quality assessment system in construction (QLASSIC) to promote the approach towards better quality delivery in the construction industry.

    • Authors: Islam Md. shafiqul
      Abstract: Design procedures based on current specifications do not always ensure required service life, mostly due to the environmental effect, error at the time of construction and underestimated cover properties at the time of design. Moreover, single-point value of any property does not provide rational support to the decision maker. Statistical resampling technique for each of the cover properties used to find out the service life of the structures is thus adopted. The results suggest the importance of the use of type of cement as a durability parameter which governs service life of RC structures.

  • Effect of Silica Fume on Recycled Aggregate Concrete
    • Authors: D. N. Parekh, Dr. C. D. Modhera
      Abstract: Use of recycled aggregate (RA) in concrete can be useful for environmental protection and in economical terms. Recycled aggregates are the materials for the future. It is a well-known fact that it gives a little lower strength than natural aggregate concrete. Though, if used up to 20% of replacement, it can give almost similar strength as that of natural aggregate concrete. Hence, it is necessary to improve strength of recycled aggregate concrete for higher recycled aggregate content. Silica fume is a very popular material used for strength improvement. Hence, popular mix of 1:1.5:3 was checked with different percentage of silica fume combination; 5%, 7% and 10% of silica fume was replaced with cement and 30%, 50% and 100% of recycled aggregates were replaced with natural aggregate and results were analyzed. Thus a total of nine trials were analyzed and conclusions were derived in detail.

  • TQM Need and Application in the Billing Process
    • Authors: Prof. Dr. S. S. Pimplikar, Anuradha A. Pore
      Abstract: This study investigates need for improvement in quality management by billing department, in the companies already certified for ISO and implementing measurement and reporting of cost of quality in the billing department. Its main purpose is to examine the gaps in the billing procedure that needs to close behind quality certification and the extent to which a firm can measure and report quality costs. A sample of 360 bills was selected at random from the department and contractor’s satisfaction for these bills measured. A questionnaire was developed and distributed to all the sample contractors. The most important uses of a quality cost report are: service cost information; quality cost planning; and targeting areas for process and service improvement. The main reason for not measuring quality costs is that the Indian construction industry, being always owner/client dominated, exhibits quality as the extensive use of non-financial measures and “quality” is not an inbuilt part of the firm’s culture. The contractor has to follow the directions of the client and scope of work and use of rights of contractors abide within the area limited by the client.

  • Assessment of Compressive Strength of OPC and PPC-Based Concretes Combined
           by Ultrasonic Pulse Velocity and Rebound Hammer
    • Authors: B. B. Das, S. K. Rout
      Abstract:  In this study, non-destructive tests were performed on ordinary Portland cement (OPC) and Portland pozzolana cement (PPC) based concrete specimens, namely the ultrasonic pulse velocity (UPV) and rebound hammer (RN). A relationship is thus established between the NDT values and the compressive strength. A statistical regression analysis was performed between the compressive strength with UPV and RN values to obtain a best-fit relationship and correlation coefficients. To take into account the possibility that the relationship thus obtained may result in a lesser fitted curve, adjusted correlation coefficients were taken into account. It was found that UPV results in more efficient prediction of compressive strength of concrete when the type of concrete is considered, while RN results in much better results when the type of concrete is ignored. However, combined UPV and RN values provided an improvement in the prediction of concrete strength and proved to be efficient and reliable closer to the actual measured strength. Further, the relationships obtained for PPC had higher correlation coefficients compared to OPC-based concrete specimens. The relationships established were also compared with other relationships from previous researchers and were found to be more consistent.

  • The Relationship between Motives and Benefits on Adopting QLASSIC–CIS
           7:2006 in Malaysia Construction Industry
    • Authors: Kenn Jhun Kam, Ahmad Hilmy Abdul Hamid
      Abstract: This paper reviews on the building contractors motivating factors on adopting the newly imposed quality assurance initiative in Malaysia’s construction industry. The quality assurance initiative named Quality Assessment System in Construction (QLASSIC) – The Construction Industry Standard (CIS) – CIS 7:2006. It is introduced by the Construction Industry Development Board of Malaysia (CIDB). This QLASSIC system consists of a building construction standard where all the contractors must follow the specifications, if adopting this system in their construction project. The literature commonly categorizes motivation factors into two types –internal and external. Both types of motivation factors, related to the benefits on adopting the QLASSIC system, are put into this study. Further analysis will be done to determine the motives and benefits relationship behind the adoption of the QLASSIC system in the construction projects.

  • Tensile Capacity of Corroded Steel Section Strengthened Using Fiber
           Composite Wrap
    • Authors: Baskar Kaliyamoorthy, R. Anandapadmanabhan, M. Anand, V. Dwarakesh
      Abstract: Strengthening and rehabilitation of structures is a major concern for researchers in the civil engineering community in recent years due to the aging of structures and the need for effective methods of strengthening. Many researches are being carried out on strengthening of reinforced concrete structures using fiber composite materials. A very few researches are being reported on strengthening of corroded steel members using fiber composite materials. Since corrosion is an inevitable problem related to steel structures, especially in offshore oil and gas industry, it is very much essential to investigate the suitability of composite materials on structural steel section. In this present study, an experimental investigation is being carried out with 26 numbers of corroded steel coupon specimens with two different fibers – Carbon Fiber (CF) and Glass Fiber (GF). Strengthening was achieved by single and double layer wrapping of FRP to the steel plates and the tests were conducted. The test results show that FRP strengthening is capable of enhancing the tensile strength sufficiently provided adequate bonding is achieved.

  • Comparison of Provision for Escalation in Various Indian Construction
           Contract Forms
    • Authors: Nitin Balkrishna Chaphalkar, Sayali Shrikrishna Sandbhor
      Abstract: Contracts provide technical assistance for implementation of works. Disputes occur between the parties involved in the contract due to number of factors. Interpretation of escalation clause is one of the reasons for disputes which necessitate proper drafting of contract terms and conditions and its extensive study. There are various construction contract formats prevalent in India which differs from one another in their provisions. Uncertainty in the cost of works executed arises due to fluctuations in the costs of labor and materials which prevail due to changing economy. Therefore budgeting for cost escalation in the planning phase of projects is very important. This paper studies contracts, claims and disputes with special reference to escalation and compares the provisions for escalation in various construction contract forms. Legal cases of escalation related disputes and their respective awards given by the arbitrators have been studied. An attempt has been made to suggest policies in existing structure of clauses to improve the price escalation system and minimize occurrence of escalation disputes at the contract drafting phase in a construction contract.

  • Planning for Optimum Maintenance Cost in Water Treatment Plants in Baghdad
    • Authors: Mohammed A. Chasib Al Mohsin, Tareq A. Khaleel
      Abstract: The main objective of this paper is to develop model to reach breakeven point between periodic planned maintenance and emergency maintenance. Hence, intensifying periodic maintenance would lead to cost increased, accordingly the emergency maintenance should decreased and visa verse. The effect of this intensifying periodic maintenance on emergency maintenance is to be determined using simulation model based on data collected for 8 working water treatment plants. Many attempts have been seen to reach this point in Morocco and Australia, however , definitely the circumstances are different from firm to another and from country to another this paper is an another attempt to prove the ability to reach optimum point of  total maintenance cost. After much iteration the result will be optimum maintenance cost. The suggested model represents a flexible technique to reach the optimal point for total maintenance cost through the process of balancing between and periodic and emergency maintenance costs.

  • Removal of Adhered Mortar from Recycled Aggregates
    • Authors: Smitha Rakessh Yadav, S. R. Pathak
      Abstract: While recycled aggregates can replace natural aggregate in making concrete without compromising strength, it is imperative to appraise the quality of the former. Quality of recycled aggregates depends upon the composition and strength of concrete from which it is derived. Thus it is necessary to identify and evaluate significant parameters characterizing a typical recycled aggregate. Adhered mortar present on recycled aggregates has been observed to adversely affect the performance of aggregates in concrete, thus its removal without affecting the properties of aggregate is essential. In this work a comparative study of various methods for removal of adhered mortar content is carried out and an effective removal method feasible for use on field is proposed.
