Slide 1:INTRODUCTION

Slide 2:WHAT IS LOGISTIC

Logistics - ...the process of planning, implementing, and controlling the efficient, effective flow and storage of goods, services, and related information from point of origin to point of consumption for the purpose of conforming to customer requirements." Note that this definition includes inbound, outbound, internal, and external movements, and return of materials for environmental purposes. Logistics Functions - (classical) planning, procurement, transportation, supply, and maintenance. Logistics Processes - (classical) requirements determination, acquisition, distribution, and conservation. Acquisition Logistics - Acquisition Logistics is everything involved in acquiring logistics support equipment and personnel for a new weapons system. The formal definition is "the process of systematically identifying, defining, designing, developing, producing, acquiring, delivering, installing, and upgrading logistics support capability requirements through the acquisition process for Air Force systems, subsystems, and equipment.

Slide 7:LOGISTIC MANAGEMENT

These are all technologically feasible projects. But it is not only the technology that determines the result. Political policy, participation and permission procedures, land expropriation, environmental impact studies, costing, budgeting and price control, logistic efficiency and safety. These, as well as many other aspects, have to be taken into account early in the plan development of real estate and infrastructure projects. It requires engineers who master the process. Engineers, who oversee, analyze and predict all aspects of the design and execution of civil engineering projects. The master Civil Engineering and Management pays thoroughly attention to both technical and non-technical aspects of planning, design, realization and maintenance of civil objects and systems. You make your own tailor-made programme by choosing a selection from our 30 modules. Of course there are some restrictions also depending on your diplomas and experience. Deficiencies up to 20 ECTS can be resolved within the master program. Depending on the choices you make, you become a specialist in one of the following three domains:

Slide 8:?Water Engineering and Management This track focuses on the behavior and management of water systems like rivers, estuaries, coastal zones and seas. Students learn about both physical and social-economic aspects of water management. Different tools are shown to analyze long-term behavior and to evaluate the impact of human interventions on different functions of the water system. Attention is also given to the role of models and uncertainty in the decision-making processes. Example topics are flood protection, water retention, water quality management, bed form development in rivers and sea.

Slide 9:?Transportation Engineering and Management This track deals with the behavior, performance and management of traffic and transport systems. Students learn about engineering, socio-economic, spatial and environmental aspects of these systems and about various aspects of human behavior in respect to their potential use. Attention is paid to both transport planning and traffic management issues. Travel demand, infrastructural supply, maintenance, impacts, performance and control are studied in an interdependent context. Different tools are used to analyze traffic systems on different scales in space and time, and to evaluate the impacts of human interventions. Example topics are area wide dynamic traffic management, intelligent transport systems, urban transport, sustainable development, traffic monitoring and evacuation planning. From a methodological perspective attention is focused on modeling, strategic planning, data fusion, evaluation methods and dynamic optimization.

Slide 10:?Construction Process Management This track is focused on the development and delivery of infrastructure and real estate projects. Students learn about the analysis, design and control of the integral construction process, the functioning of construction process organizations and the coordination of the activities and roles of parties involved. The various sub-processes of the total construction process from conception to demolition are studied integrally. Plan development management at conceptual phase, public-private partnership, design management, sustainable building, risk analysis and management, IT and logistics as well as market and organizational forms are topics of courses.

Slide 11:CONSTRUCTION PLANT

Construction plant can be classified according to their functions as:- Excavating Hoisting Transporting Mixing

Slide 12:Excavating Factors in selecting Excavation plant:- The nature of the excavation to be performed The type of soil to be excavated The distances which the excavated spoil must be carried to transport The condition and gradients of the site Excavating plant can be divided into two types:-

Slide 13:a. Excavator It is an equipment to be based on which is a tracked or wheeled self-propelled machine consisting of a chassis carrying a revolving platform and a power operated jib or boom controlled by wire ropes, together with a driver�s cabin, and which is designed for a number of different excavating operations by changing the booms and buckets. An excavator can be rigged as:-

Slide 14:Face Shovel It is used for excavating against a face or bank, consisting of an open-top bucket or dipper with a bottom opening door, fixed to an arm or dipper stick which slides and pivots on the jib of the crane. It is suitable for excavating all clay, chalk and friable materials and for handling rock and stone. However, it is not suitable for surface excavation for which a skimmer is used. Backacter It is similar to face shovel except that the dipper stick pivots on the end of the jib and the dipper or bucket works towards the chassis and normally has no bottom door but is emptied by swinging away from the chassis to invert the bucket. It is mainly used to excavate trenches and occasionally used for the excavation of open areas such as small basements.

Slide 15:Skimmer This arrangement is similar to the face shovel except that in this case the bucket slides on rollers directly along the jib and thus has a more restricted movement. It is used for surface excavation and levelling in conjunction with transport to haul away the excavated material. Dragline It is usually fitted with a long slender boom or jib and the bucket, which in operation faces towards the machine and has no door, is supported by cable only as on a crane. It works from the side of the excavation at normal ground level and is used for excavating large open excavations such as basements when the depth is beyond the limit of the boom of a backacter.

Slide 16:Crand and Grab It consists of two hinged half-buckets or jaws pivoted to a frame which is suspended by cable from a long jib of an excavator. The grab is used for deep excavations of limited area on all types of soil except rock. Pile Driving and Drilling It is an excavator equipped with either hanging leaders which guide the pile and the hammer during driving, or a turntable through which the square drilling rod or kelly bar passes for drilling piles.

Slide 17:b. Tractor-based Equipment It is designed either as attachments to normal tracked or wheeled tractors or as machines in whih the earth-moving attachments and the tractor are designed as a single integrated unit. A tractor which is hydraulically operated can be rigged as:- Tractor Shovel This consists of a tipping bucket at the front attached by strong pivoted arms or booms to the frame of the machine. It is used for stripping top soil, excavating against a face, bulldozing and for loading spoil or loose materials. Trench Digger It operates on the same principle as a backacter excavator except that the bucket is controlled by hydraulic rams instead of cables and pulleys.

Slide 18:Scraper It is a large box or bowl with an open front and bottom cutting cutting edge, supported on a frame between two pairs of wheels and attached to a tractor from which the bowl is raised and lowered by cable or hydraulic power. It is used for surface excavation over large areas where the spoil can be disposed on the site and for bulk excavation over small areas. Bulldozer and Angle-dozer The bulldozer consists of a rectangular steel blade with renewable cutting edge set at right-angles or about 30 degrees to the direction of travel and attached by steel arms to the sideframes of a crawler tractor. It may be used for excavating natural soil or for moving loose soil or debris which it pushes forward as the ractor forces it ahead.

Slide 19:4.2 Hoisting This concerns with the handling of materials and components. Most building materials used in the erection of buildings are handled several times during the course of construction. The plant used for hoisting, primarily performs vertical movement. Mobile Cranes These may be either self-propelled or truck-mounted. They are suitable where on-site or between site mobility is a primary requirement or where the duration of job is short. It is widely used for the erection of low-rise buildings where a long reach is not essential and the machine can approach near to the building, and for the erection of low framed structures where the crane being able to move between the columns of the structures. For example: Self-propelled cranes, truck- or lorry-mounted cranes, telescopic jib cranes Stationary Cranes They are fixed firmly to some form of base at their working position. It can handle its maximum loads over a greater range of radius than mobile crane. For example: Derrick cranes, guy derrick, scotch derrick, monotower derrick, tower crane, climbing crane, rail-mounted or travelling crane, transportable tower crane, fixed jib slewing crane, portal crane

Slide 20:Hoists A hoist consists of a horizontal platform which is moved up and down vertical guides by a powered winch and is usually termed a platform hoist. It is used for materials lifting and passenger carrying which is useful for high-rise building construction. For example: Platform hoists and mobile platform hoists. Elevators These consist of a series of buckets fixed to a rotating belt or chain and are used for raising aggregates into the bins of weightbatchers. Elevators can work vertically but are usually set at an angle, according to the height of lift.

Slide 21:4.3 Transporting This implies horizontal movement primarily but it can involve some vertical movement too. Dumpers These are vehicles designed for the transport of materials which previously were usually carried out by wheelbarrows, such as excavated spoil, hardcore and concrete. It is faster and more economical than hand barrow and consists of a shallow tipping hopper or skip mounted on a wheeled chassis. For example: Power barrow, dumper, multi-skip dumpers, high discharge dumpers, dump truck Forklift Trucks It is essentially a powered mobile chassis on the front of which is a vertical frame or mast on which a pair of "forks", that is a pair of projecting tines, may be raised and lowered. It is basically used for handling unit or packaged loads which is a large individual component or smaller components packaged into suitable units.

Slide 22:Monorail Transporter This is a powered wagon or skip running on a single easily laid rail and is intended primarily to carry concrete from the mixer to the point of placing. It is generally used in otherwise inaccessible situations. Conveyors It is used for handling small materials such as excavated spoil from the point of excavation to the boundaries of the site for loading into transport, for concrete placing or for filling up aggregate bins in weigh-batchers. Concrete Pumps and Placers This consists of a pump which is mechanically operated by ram and placers pneumatically operated by compressed air. For example, mobile concrete pump.

Slide 23:4.4 Mixing A large amount of material must still be mixed with water, mainly concrete, mortar and plaster. The advantages of mechanical mixing over hand mixing, except for very small quantities, are greater economy, reduce the loss of cement and more accurate gauging of the water content. a. Concrete Mixers They are made in various types and sizes and are broadly classified as (i) batch mixers and (ii) continuous mixers. There are five types of batch mixer: Tilting drum Non-tilting drum Reversing drum, a form of non-tilting mixer Split drum Paddle mixers (a) pan (b) turbo (c) trough

Slide 24:b. Weighbatchers The batching of materials for concrete may be by volume or by weight. For example: weighbatcher incorporated with mixer, independent weighbatcher, mobile and semi-mobile weighbatcher c. Central Mixing Plant The concentration of batching and mixing operations in a single static plant instead of by a number of mobile mixers is often used on large, extensive sites. ��The main advantages of central mixing are:- An increased output by fewer machines and men is possible. In suitable circumstances it is more economicl than a number of separate mixers. Better quality control is possible The essential components of a central mixing plant are:- Adequate storage of aggregates at ground level Overhead aggregate storage bins to hold not less than an hour�s supply at maximum output Some means of storing and weighing the cement Elevated water storage together with some means of metering the water supplied to the mixer A mix or mixers Storage hoppers to contain the mixed concrete until fed into transport or concrete pump.
