  • Identification and Prioritization of CSFS and Perception of the Stake
           Holders for Fast Track Construction Projects in Pakistan

    • Authors: Mustafa Sultan, Shahid Iqbal, Hassan Farooq
      Abstract: Construction industry is characterized by its unpredictability in terms of time and cost. Worldwide 85% of the projects suffer time overrun resulting in cost increase. Project management being a neglected aspect in Pakistan results in project time overrun. Many scheduling techniques are employed to regain the lost schedule, fast tracking is one such technique. Fast tracking is overlapping the project activities in order to reduce project duration with increased activity and project cost. Globally fast tracking has seen ages of practical implementation since 1960s. However being a newer trend in Pakistan, it is yet to witness maturity. Fast track projects opt for time and quality over cost and in fast track projects we accept the tradeoff between the high cost of buying time while maintaining quality. The main idea behind fast tracking is to overlap the activities which otherwise are executed in sequence. Particularly the emphasis is kept on overlapping design and the construction activities. After an extensive literature review a preliminary questionnaire containing 93 success factors was used for the pilot survey. After the pilot survey full scale survey questionnaire was prepared containing 45 success factors. The questionnaires were sent to a sample size of 63 comprising of the contractors, consultants and the construction clients. The data collected was analyzed using PASW-18 and MS Excel. After conducting the statistical tests the success factors were ranked in order of importance using RII and mean values. Keeping the mean value as the yard stick, success factors with mean value of 4 and above were identified and prioritized as the CSFs (Critical Success Factors). Similarly the stakeholder’s perception on the CSFs was also evaluated. At the end conclusions and recommendations were formulated. Keeping in view the research parameters, the research’s contribution is twofold, one to the local CI (Construction Industry) and other to R&D (Research and Development) community.

           Behaviour of Soil

    • Authors: N. Sathish, J. Donjayaraj
      Abstract: Sugar industries plays major role in the environment pollution. The organic effluent (spentwash) discharged by such industries is one of the most complex, troublesome and strongest organic industrial effluent having extremely high BOD and COD values. Assessment on the effect of sugar effluent application on inorganic pollutants (pH, EC, alkalinity, chloride and sulfate, TS and TDS) and organic pollutants (COD, BOD, TVS) were evaluated in laboratory experiment. The soil - pollutant interaction was critically analyzed and reported to explain the effect of sugar effluent on commercial (bentonite) and natural soil properties. The experiments were conducted under batch and continuous mode operation usingsugar effluent contaminated soil samples with highly clay and silt content. Application of sugar effluent improved the physical and chemical properties of soil by reducing the bulk density and increasing the water holding capacity.  The present study showed that the sugar effluent was highly loaded with organic pollutants along with harmful heavy metals which showed significant effect on soil quality and chloride, sulfate present in sugar effluent was reduced by adsorption of sugar effluent through the soil. In this investigation soil columns were developed, and effect of liquid limit, plastic limit and shrinkage limit under expansive and normal soil conditions evaluated of any of soils have been used. COD reduction was achieved ~20 to 48%. Keywords: Sugar Effluent, Physico-chemical behaviour, commercial and Natural soils, Soil – pollutant interaction, Atterberg limits.

  • Geotechnical and Geochemical Properties of Lateritic Profile on
           Migmatite-Gneiss along Ogbomosho-Ilorin Highway, Southwestern Nigeria

    • Authors: Okunlola I. A., Amadi A. N., Dindey A. O, Kolawole L. L.
      Abstract: Lateritic soils are very important in the construction industries and activities as construction material and foundation support for engineering structures in the tropical regions. This research tends to focus on the influence of position of horizon within the laterite soil profile and the resultant geotechnical and geochemical properties of soils developed over migmatite gneiss rock and also examine their suitability as construction and /or foundation material. A total of twenty three (23) soil samples and two rock samples were obtained from 8 different locations along Ogbomosho – Ilorin Highway, Southwestern Nigeria and considered under this study. The area is underlain by Basement Complex rock and migmatite gneiss is the most widely spread rock type. The laboratory test carried out includes specific gravity, grain size analysis, Atterberg limits (liquid limit, plastic limit, plasticity index and linear shrinkage), Standard proctor test, California Bearing Ratio (CBR), and Shear test. Geochemical analysis for major oxides and thin sectioning of rocks for petrological analysis was also carried out. The oxides are SiO2, Al2O3, Fe2O3, K2O, Na2O, TiO2, CaO and MnO while SiO2, Al2O3 and Fe2O3 constitute about 70-80 % of the soils chemical composition. Petrology reveal strongly foliated rock that composed of mafic mineral such as biotite, hornblende, and felsic mineral consisting of quartz and feldspar. Quartz, biotite and feldspar constitute about 77% of the minerals with quartz having 40% of the total mineral composition. The position of the horizon within the soil profile was found to have varying influence on the plasticity, moisture density relationship, CBR, and shear strength. This study showed that the influence of the parent rock on engineering properties and the position of the horizon within the lateritic profile determine the engineering properties and behaviour of residual soils.

  • Use of Water Pollution Index to Assess the Levels of Dissolved Organic and
           Inorganic Substances in Nworie River Owerri, Imo State Nigeria

    • Authors: Umunnakwe Johnbosco E., Nnaji; Austin O.
      Abstract: The use of water pollution index to assess the contributions of organic and inorganic parameters in the pollution level of Nworie River was studied in the month of October, 2014. An index represents the results of generated field data in a simple and generalised way by mathematically combining sets of values obtained. The pollution indices of water and sediment samples during dredging of the river in 2010 and in this present study were presented and comparisons made. This investigation surveyed the following parameters for both surface water and sediment samples: pH, Temp, Phosphate, Nitrate, Sulphate, Iron and Lead, while turbidity, conductivity, Alkalinity, Carbonate, Hardness, DO, BOD5 TSS, were included in surface water analysis. Three sampling stations along the stretch of the river were selected: Federal Medical center, Akanchawa Road and Egbeada and standard methods were adopted for their sampling and analysis. The result of the analysis indicates that turbidity and total suspended solids exceeded the standard limits for surface water, while iron exceeded that for sediments. A DO of 5.7mg/l shows that the river could sustain aquatic life. The results of the computed pollution index revealed that the index of organic parameters  was 0.42 while that of inorganic  was 0.34.During the dredging of the river in 2010 organic parameters had an index of 0.48 while inorganic had 0.30.For sediments, organic variables had a score of 0.08 while inorganic had 0.02 score. During the dredging in 2010, the index of organic parameters for sediments was 0.13, while for inorganic vsariables it was 0.053.The pollution indices strongly implicated pollution by organic wastes which were higher during the dredging of Nworie River. Keywords: Pollution index, organic, inorganic, Nworie River.

  • Geotechnical Application for the Design and Estimation of Amata-Lekwesi,
           Nigeria Open Mine

    • Authors: Aitsebaomo F. O., Ngerebara O. D., Teme S. C., Ngah S. A.
      Abstract: The need for a proper understanding of the subsurface geology of a place and the depositional pattern of what is to be mined is very important in establishing its mining trend especially if such deposits are not exposed at the surface. Eleven borings were made in the quarry pit and around the surrounding berm to depths of 25 meters at a sampling interval of 1.0m into the intrusive rock bodies using Slanzi rotary diamond coring rig. The depth range of the boreholes varies from 15.0 meters to 25.0 meters. Rock/Soil samples obtained from borings were subjected to both visual field examination and laboratory tests/analyses to guide in designing a mine system that is based on the geology, trending pattern and geotechnical properties of the rocks. The intrusive was observed to trend in the east-west orientation. However, north-south trends were also observed at certain sections of the mine/quarry. The values of the plunges of the intrusive were observed to be between 2o and 6o at the northern southern segments.
