Curious Civil Engineer

 Construction management: Road construction course This course is designed to expand your practical side of engineering knowledge. This course is concentrating on the construction of roads. Here you will learn how the road is constructed. The construction stages such as protection of existing services, clearing the area, future utilities, preparing the road subgrade, then placing different pavement layers such as sub-base, base course, and asphaltic courses. We will also discuss the types of asphaltic course and the common defects of asphaltic pavement, such as permanent deformation, fatigue cracking, and low-temperature cracking. Also, I will show a typical cross-section of road and road profiles and many other subjects. Enroll from here  Pile foundation design This course will discuss the design of pile foundations. We will learn the methods of calculating the pile bearing capacity. The bearing capacity for a pile consists of skin and end bearing resistance. Here you will understand

Project network is a graphical representation of project activities using arrows and nodes, the project should have unified start and end date, drawing this network required identifying for each activity the predecessors, duration for the completion of this activity and resources. The project network can be drawn using activity on arrow network and activity on node. construction management: concrete construction bridge construction:How to become a bridge engineer Activity on node network (AON) In this method, the node used to represent project activities, and the arrows between activity will be used to describe the relations between project activities. From figure 1, network one. We can notice that activity B depends on activity A only. in network 2, activity D depends on C and C depends on A and B. AON methods allow for representing lag and lead of activities on the relationship arrows that connecting different activities. Figure 1 construction ma

project network is a graphical representation of project activities using arrows and nodes, the project should have unified start and end date, drawing this network required identifying for each activity the predecessors, duration for the completion of this activity and resources. the project network can be drawn using activity on arrow network and activity on node. construction management: concrete construction bridge construction:How to become a bridge engineer Activity on arrow network (AOA) activity on this method represented by an arrow, while the nodes represent the start and end for activity, the lenght of area has no significant effects. figure 1 showing AOA network. in network number 1, activity B cant start before activity A completed. 5 and 10 represent the start and for the activity.  there some important point you should follow: Each activity should have a unique i and j, i will be placed inside the rear node while j at head node, i>j. it is re

lead is the process of acceleration of conducting successor activity by starting the successor activity before the finish of previous activity, this can be done if there are no physical or technical constraints on starting with successor activity before completion the precedent activity, this will occur in FS type of activities. an example of this is the fixing of formwork and casting of 50 columns for a building, fixing formwork required 4 days. instead of waiting for 4 days, to begin with, casting, we will start casting from day one. skilled engineers will always utilize all the available manpower and equipment. also, they will reduce the time of performing the job by overlapping the activities as much as possible without reducing the quality of the work.  Figure 1 construction management: concrete construction bridge construction:How to become a bridge engineer lag is the delay of successor activity after the completion of the precedent activity. lag represent

project activities are related to each other, different relationship link project activities, knowing the type of relationship of activities will assist the project team in providing efficient plans and properly utilizing available manpower and equipment, knowing the type of relationship required good experience for a similar type of work, as engineers we need to answer following question for each activity: what activities should finish before proceeding with this activity? what activities should be executed at the same time with this activity? what activities should begin after the completion of this activity?    construction management: concrete construction bridge construction:How to become a bridge engineer Let take an example of casting a building slab, concreting of building slab cant be done if we didn't place the reinforcement, similarly reinforcement cant be placed if we didn't install formwork and so on,  our activity is slab casting, before cast

The smallest unit of WBS is a project activity, project activity defined as any function or decision in the project that consumes time, resources and cost. project activity is a unique unit with a specified time, project activities can be divided into three groups based on the nature of the activity: Production activities: excavation, steel fabrication, formwork, and concrete casting activities are examples of production activities, production activities involve using of resources such as labors, equipment, and materials, production activity will have a specified quantity, resources time and cost. production activities for a project can be determined easily by studying project shop drawing and specifications. Procurement activities: this activity involves procuring the required materials and equipment for production activities, procurement activities will have a specific time, delaying of procuring required material will result in delaying the completion of production activities

Work breakdown structure can be defined as a hierarchical structure that designed to give a logical graphical representation and subdividing all work activities. Figure 1 showing a WBS, WBS can differ from a project to another. The full scope of the work will be placed at the top of the diagram, in figure 1 our full scope is to build a house, then we subdivide the works into small elements at each level of the diagram, in figure 1. we divide the works in the house into 3 categories: civil, plumbing and electrical. Then we subdivide civil into smaller work elements such as foundation, walls/roof, the lowest level of the diagram known as a work package. A list of work activities will be developed from the work package. Figure 1 construction management: concrete construction bridge construction:How to become a bridge engineer effective WBS will summarize the full scope of work and the responsibility for each work package, for example, for the work package foundati
