    In comparison with the option of “flatten and rebuild buildings”, durability can be better achieved by extending the life spans of existing structures. Strengthening of structures results in less construction waste materials, reserves natural resources, minimizes adverse environmental effects, saves time, saves cost, etc. The structural behavior of reinforced concrete beams strengthened steel sheets has been determined in the undertaken research both theoretical and experimental. The main aim of our project is to highlights the best among the investigated strengthening techniques. The experimental work included complete research plan consists of 6 concrete cylinders and 9 concrete beams. Making concrete (6 concrete cylinders, 2 for each strength & 6 beams 2 of each strength, 3 for control sample 3 for steel sheet sample) with different strength properties (strength range 18MPa, 21MPa and 25 MPa).to have inadequate flexural capacity and the purpose is to increase it. Strengthening operation has been accomplished using concrete steel sheets with different configurations. The test variables included the type of strengthening flexural the technique of strengthening. As predicted, the strengthened beams exhibited different structural behavior upon loading up to failure. The beams strengthened with epoxy bonded steel sheets showed best structural behavior. Steel sheets bonded at the bottom of the beam can prevent the shear failure and recover flexural capacity while continuous steel plates bonded to bottom sides of the beam only delay the shear failure with increasing in flexural capacity. In conclusion, strengthening of Steel sheet beams can be effectively increase by 22% to the control beams achieved using practical techniques, which will increase the life spans of the beams and thus enhance the durability of existing structure.

    Minimizing clash related delays in building construction by adopting building information modeling
    (UMT.Lahore, 2020) Azhan Umer; Junaid Azhar; Nabeel Hassan
    Building projects involve complex processes, extensive planning and multiple stakeholders. Due to this intricacy, building projects are difficult to manage and often face delays. According to literature, major cause of these delays are clashes between various building elements, which typically take place due to lack of communication among different stakeholders. The recent advancement in information technology has introduced various tools to curb this problem. Building information modeling (BIM) is one of the emerging tool that has potential to reduce the negative impacts of these factors by providing better visualization, simulation and collaboration of design and information throughout the lifecycle of project. Despite all these advantages, underdeveloped countries are still far behind in implementing BIM in construction industry. In order to identify and highlight the potential benefits of BIM in local construction industry, this study investigated the benefits of BIM and how it can help in rectifying the most frequently occurring construction delays. Further, BIM was implemented and clash detection analysis was performed on an ongoing residential building project. The finding of the study, highlighted the importance of adopting BIM and its positive impact on building projects. It was also concluded that the clash detection analysis can help in reducing time delays. The construction industry must adopt BIM techniques to get the optimized cost and time for the project. This is first of its nature study in term of local construction industry

    Seismic analysis of underground water tank
    (UMT.Lahore, 2020) ZUBAIR UMER; MAKHDOOM REHAN; ARSLAN SHAHID
    The Underwater Water Tank has been a major and most important part of almost all projects. Due to the growing daily population, it is necessary to provide water for various purposes such as industrial use, agriculture, domestic use, for the purpose of drinking etc. Water conservation is best done by providing an underground water tank. This study investigates a well-made cement-backed land with a rectangular water tank under the quake's epicenter. Elemental dimensional finite elementary analysis and SAP2000 software were used to predict tank response. The parameters of the variable analysis considered are the aspect ratio (height of the tank to the maximum length) and the water level of the tank, while the size of the tank wall is considered to be constant. The transcendental and non-volatile masses are also represented by the spring weight model in the historical analysis of the period of earthquake recordings. In general, the results show that, there is a smooth increase in current and displacement of hydrostatic and hydrodynamic analyzes with a decrease in the factor ratio. The high migration time and hydrodynamic impact time are greater than the hydrostatic effects

    (UMT.Lahore, 2020) Syed Mohd Shehzad; Muhammad Umair Tahir; Syed Mohsin Sherazi; Rana Asad Liaqat
    Floods are the most frequent, widespread and disastrous hazards of the world. Almost every year, Kalam River is affected by floods though its nature and impact differs due to complete different geographical and hydrological setting. This study aims to develop Hydrologic Engineering Centre’s Hydrologic Modeling System (HEC-HMS) model for Kalam River basin to analyze the effects of rainfall on surface runoff and peak discharges of the river and ultimately produce flood inundation levels to assess the flood risks in Kalam River. Being a rain-fed catchment, the flood discharges of Kalam River are highly affected by the extreme rainfall. A HEC-HMS hydrological model was set up in order to carry out the rainfall runoff analysis. HEC-HMS model gave the discharge values of each year by analyzing the precipitation values and Digit Elevation Model (DEM) of Kalam River basin. From these discharge values the flood risk of the region was estimated. Keywords:

    Compaction characteristics of soil mixed with plastic waste materials
    (UMT.Lahore, 2020) Syed Mir Wais Shah; Abdul Qadir; Fabiyan Naeem; Abdul Qadir Jillani
    Compaction of soil is commonly used in earthwork construction like soil sub grades for pavements, embankments/dams, backfills etc. The main purpose of compaction is to accomplish higher quality, lower compressibility, and lower penetrability of soil. Soils behave differently for the different combinations of unit weight and moisture content. While there can be positive impacts of compaction, compacted clayey soils can cause serious problems when they are in contact with water, e.g. soil swelling etc. Compaction control is the most economical way to avoid undesirable effects on the construction characteristics of soil and to get more quality of soil. Soil properties vary due to variation of soil parameters in the field. Therefore, it is exceptionally basic to examine the behavior of clay under changing parameters. This study is basically on placement conditions of plastic waste material (PWM) on varying percentages. This research work included the compaction of clayey soils and the performance of unconfined compression test of soil and California bearing ratio test. The laboratory testing on the sample of Narowal clay included particle size analysis, moisture content determination, specific gravity, Atterberg limits, compaction test, unconfined compression test and California bearing ratio test. All these tests were performed according to the applicable ASTM standards CBR value at 0% of PWM was 5 unconfined compressive strength was 202kpa after adding 0.5% PWM then CBR value was 6 and unconfined compressive strength was 300kpa, at 1% of PWM CBR value was 8 and unconfined compressive strength was 352kpa and after adding 1.5% PWM CBR value was more increased up to 10. So it’s also shows that addition of plastic waste material in clayey soil increases the value of CBR and unconfined compressive strength

    Sediment evacuation from tarbela reservoir
    (UMT.Lahore, 2020) Aaqib Farooq; Abdul Haseeb; Haris Miqdad; Muhammad Saad ul Hassan
    Tarbela is one of the world's largest water resource development projects. The Project is the capstone of the Indus Basin Treaty providing an improved supply of water to irrigated land in Pakistan as well as generating electricity and allow some control of floods. River Indus and its tributaries, namely Shyok, Gilgit, and Hunza carry significant sediments into the Indus river. Most of these incoming sediments are being trapped in the reservoir and deposited in the upper reaches of the reservoir. A part of the sediments escapes from the reservoir through the outlets while a huge amount of the sediments gets accumulated as a major delta. At lower sediment loads it is possible to manage these deposits by sluicing through the dam which can be achieved at times of high flows. However, at periods of repeated high flows, as will occur with Tarbela Reservoir flushing, the sand bars build up. In the power channel, the development of these sand bars across the entrance will create problems and result in a head drop. If the Tarbela reservoir is operated to draw more sediment out of the reservoir then turbines of Tarbela will be subject to greater sediment load. The analysis was carried out by HEC-RAS model , it was used to simulate different scenarios for flushing through the Tarbela dam. For this purpose the hydrological data including sediment inflow, outflow, 10 daily discharges from 1979 to 2017 was collected from WAPDA. The simulated and actual profiles in terms of sediment deposition, sediment outflow, and remaining capacity was calibrated and validated for the years 2009 and 2012 respectively. The longitudinal profiles, which provided an understanding of the rate of advance of the delta, the foresee slopes, and in which areas of the reservoir the incoming sediment is accumulated. The delta is estimated to arrive at the dam by the year 2033 and the sediment outflows start to increase (the average once the delta arrives is 100 MT with less amount of sand). Clearing sediment from around the intakes is unlikely to be of significant value as the area should be cleared more effectively by the sluicing effect of the discharge through the tunnels
