    In the site of a contract of developing and constructing a new International Airport

    Items to be executed are

    Cutting and Dozing

    Transportation of Surplus earth

    Bringing sand and spreading and leveling

    Procurement of Bitumen

    First to select excavator we need to know the types of excavator and functions.

    Excavators are heavy construction equipment consisting of a boom ,stick, bucket and cab on rotating

    platform (known as a house)The house sits atop an undercarriage with tracks or wheels. A cable

    operated excavators uses winches and steel ropes to accomplish the movements. They are a natural

    progression from steam shovels and often called power shovels .All movement and functions of a

    hydraulic excavator are accomplished through the use of hydraulic fluid ,with Hydraulic cylinders and

    Hydraulic motors. Due to linear actuation of hydraulic cylinders, their mode of operation is

    fundamentally different from cableoperated excavators.

    Excavators are also called a JCB (which is a proprietary name) or 360-degree excavators sometimes

    abbreviated simply to 360.Tracked excavators are sometimes called trackhoesby analogy to the

    backhoe.

    Hydraulic excavator capabilities have expanded far beyond excavation tasks with buckets .With the

    advent of hydraulic powered attachment such as breaker ,a grapple or an augur, the excavator is

    frequently used in many application other than excavation. Many excavator feature a quick coupler for

    simplified attachment mounting, increasing the machines utilization on the jobsite. Excavators are

    usually employed together with loaders and bulldozers. Most wheeled .compact and some medium

    sized (11 to 18 tonne)excavators have a backfill(or dozer) blade. This is a horizontal bulldozer-like blade

    attached to the undercarriage and is used for leveling and pushing removed material back in to the

    place.

    SHOVELS

    Excavators where the digging action is an upward motion are called front shovels or just shovels. The

    front shovel perform excavation by crowding the material away from the machine. They are mainly used

    for digging above the track level and loading the material into hauling units. Thus they are suitable for

    use in quarries for loading of blasted or short rocks. A typical modern shovel is depicted in the diagram

    A front shovel has the capacity to develop high breaking force. This is required as the material being

    excavated should be such that it will stand on its own almost at a vertical face. And normally such

    material are rocky in nature. Usually the front shovel are mounted on track base and have a slow

    traveling speed. The other basic parts of a shovel consist of the mount, cab, boom, stick and the bucket

    as shown in the figure below. The size of a shovel is indicated by the weight and bucket size.

    A front shovel has to be close to the material to be excavated before it begin excavating. When this is

    achieved, the bucket is lowered to just above the track level with the bucket teethes pointing into the

    material face. A crowding force is applied by hydraulic pressure to the stick cylinder and at the same

    time the bucket cylinder rotates the bucket through the face.

    The bucket will be fully filled if the height of the of the excavated material is right. If the material height

    is too low a second pass will be required. Then once the bucket is full it just tipped over to load the

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    4/27

    material into hauling units. Finally the material left on the pit floor will be excavated after the upper

    material is excavated.

    Back Hoes Description and Uses

    Initialy introduced in the United states as back-hoe.the hydraulic excavator is largely a European

    development .Line production in the 200 to 240 ton class is currently available from 3 to 4

    manufactureres .In the back hoe mode the hydraulic excavator can stand on top of a bench and load a

    truck spotted on the bench below.Due to the small swing angle cycle time is short resulting in high

    production.The life of hydraulic excavator is about 8 to 10 years.

    Excavators where digging action is a downward arch motion are known as backhoes or hoes and

    Even back shovels.Thus they are used to excavate below the ground surface or below the machine track

    Level.Back hoes being mounted on crawler tracks can also be mounted on a wheel base.

    Wheel mounted excavators are not specifically for bulk excavation but designed for mobility and general

    purpose works. The John Deere excavators and JCB excavators are the most well known examples of the

    wheeled based types. A typical modern back hoe and it's key components are depicted in the diagram

    below.

    Uses of back hoes

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    5/27

    These machines are suitable for excavating trenches, pits for basement and smaller machines can

    handle general grading work. It is a versatile machine in that it can perform both excavation and lifting

    works. Example in drainage works or utility works , the back hoe can perform the trench excavation and

    handle the pipes or culverts. Thus this makes the need for a second lifting machine unnecessary.

    During excavation the penetration force in to the material being excavated is achieved by the stick

    cylinder and the bucket cylinder. The buckets can be selected depending on the type of material

    excavated. For easily excavated material wide buckets are used. When excavating rocky material or

    blasted rocks, a narrow bucket is used. In utility works, the width of the required trench is the deciding

    factor in selecting the bucket.

    Mini Excavator Description and Uses

    Mini excavators are small, compact machines that range in size from under 2000 kg to 6000kg (4409lb to

    13227lb) and with bucket sizes between 0.02m3 to 0.17m3 ( 0.026yd3 to 0.222yd3 ). Like their larger

    cousins, these excavators also consists of a cab, a boom arm, a bucket and mounted on top of crawler or

    wheeled base. Usually the machine is equipped with a backfill or bulldozer blade that attaches below

    the boom. This make it easy to refill and level the material after digging works without having to change

    attachments.

    Despite their size, mini excavators are extreme versatile. Machines in this class typically have digging

    depths from 6 to 8 feet and their relatively powerful hydraulic systems allow these machines to run a

    host of attachments, including hammers and breakers for light demolition work. Further more with

    retractable undercarriages, this allow them to contract to widths as small as 40 inches to get through

    tight areas. Then when the machine is in position, the tracks are expanded out to their working width.

    These traits, combined with their compactness, high maneuverability and easy transportation

    characteristics make them suitable for working in restricted surroundings. Thus these machines are used

    in utility, light demolition, home repair or renovation application. They however can also be used to

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    6/27

    complement bigger machines or even work in conjunction with them. As an example, a mini excavator

    can be paired with a wheeled based front shovel. Such pairing can be applied to jobs like the

    construction of a residential swimming pool. The mini excavator can dig while the skid-steer loader

    removes the material and loads it into a dump truck.

    Buldozers

    Although not usually employed as a primary excavator the Buldozer has considerable application in

    surface mining. The crawlermounted machine is more generally accepted and 70 Ton units are at

    present in operation but because of its mobility the rubber-tired bulldozer is increasingly finding

    application.For short hauls in severe conditions where scrapper operations would be difficult bulldozing

    can usually be adopted.

    Material Management

    1) In modern management, Time plays a great role. Right decision at right time is the needof hour. All the decisions are based upon the past data or information and as such with

    the change in technology and other developments, it is necessary that the decision be

    based on the latest information, for which a sound data processing system is called for.

    The materials manager who wishes to utilize a computer in the operation of his

    department does not have to understand its electronic intricacies. He should, however,

    know generally what a computer can do, what it cannot do and how his departmental

    procedures must be designated so as to be compatible with computer operation.

    Effective use of a computer offers a manager several significant advantages.

    Computing ability to process huge volumes of data rapidly. Freeing the personnel from routine clerical work and repetitive tasks.

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    7/27

    Enable departmental personnel to do more creative work. Immediate availability of much more complete data for use in decision making.

    The materials management activities which can be performed by computerized system

    are the same in all cases. They are

    Posting of inventory records. Computation of economic order quantities. Preparation of purchase requisitions. Preparation of purchase orders. Distribution of accounting charges. Automatic preparation of follow-up memos. Posting of delivery and quality records, by part and by vendor. Preparation of numerous operating reports for management. Auditing of invoices and preparation of cheque for payment of invoice.

    INTEGRATED MANAGEMENT INFORMATION SYSTEM :

    The system using computers can generate various types of information / reports depending on the

    requirements. Following list gives a list of few reports used in materials department. The list is only

    illustrative and not exhaustive.

    Long-term production schedule. Short-term schedule. Materials manual.

    Requirement of non-stock items from user departments. Information regarding lead time, supply position (shortages), price trends, anticipated

    price changes, etc.

    Production Schedule handed over to production department. Materials requisition from the production to stores. Materials supplied from stores to production. To and fro information between stores and inspection. Information regarding receipts from the stores. Date regarding issues from stores. Due dates of supply from purchase department. Information to purchase department for follow up of supplies. Purchase requisition to purchase department. Purchase order. Materials from suppliers to stores. Previous years consumption data.

    OPERATIONAL AND EXCEPTIONAL REPORTS :

    The following operational / exceptional can be obtained from the computer. Here again the list is not

    exhaustive.

    It is possible to get the following exceptional reports for managerial purpose.

    Items for which consumption is morel than the norms Items for which there is a supply shortage and anticipated price increase Items with stock level above maximum norms Obsolete items

    Computerization can be of great help to meet the following objectives of materials

    management.

    Accurate and speedy remittance of information to customers and suppliers, bills,statements, reminders, etc.

    Information for management for control purposes e.g. stock levels, inventory position,customers acceptance etc., etc.,

    Improvement of customer relations, vendor and employee relations, by timely accurateand relevant information and thro vendor analysis etc.

    Reduction of inventories to free the working capital. To increase profits at the same time giving better service by optimum scheduling,

    forecasting and optimizing utilization of traffic facilities, warehouses, machines, etc.

    To increase the productivity of materials and facilities.2)Lead time is the period between a customer's order and delivery of the final product. A small

    order of a pre-existing item may only have a few hours lead time, but a larger order of custom-

    made parts may have a lead time of weeks, months or even longer. It all depends on a number

    of factors, from the time it takes to create the machinery to the speed of the delivery system.

    Lead time may change according to seasons or holidays or overall demand for the product.

    Manufacturers are always looking for ways to improve the lead time on their products. Lead

    time can mean the difference between making the sale and watching a competitor sign the

    contract. If a company can deliver the product weeks ahead of the competition, it stands a

    better chance of receiving future orders. Because of this, management and labor teams

    routinely hold meetings to discuss lead time improvements.

    For a real world example of lead time in action, let's order a pizza. When you as the hungry

    customer decide on a preferred local pizza restaurant, you may have already considered such

    factors as speed and consistency. The selected restaurant must first receive your custom order,

    based on their pre-stocked ingredients. Once you've placed your order, the restaurant may tell

    you to expect the finished pizza in 45 minutes to an hour. This would be considered lead time.

    The restaurant bases this time on several factors: the time it takes to prepare the pizza, the

    cooking time, the availability of delivery drivers and the distance to your home.

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    11/27

    As the potential customer, you could still change your mind and place an order with a different

    restaurant known for its speedy delivery times. The same style of pizza may arrive in 30

    minutes. It's an identical product, but the lead time is different. This other restaurant may use

    prepackaged pizzas or hire more delivery drivers. There may be some limitations on delivery

    areas, however, or the pizza may not be cooked well. Sometimes a shorter lead time is no

    guarantee of overall quality. Lead times may also change according to the day of the week --

    demand may be higher on weekend nights, for example, creating a longer lead time.

    This is the challenge many companies face when attempting to improve lead time on a product

    line. Some processes simply take more time to create a high quality product. A custom order

    may require months of preparation before the factory is capable of mass production. It can be

    challenging to offer a competitive lead time to the customer while still maintaining quality

    control over production. Companies must remain realistic with their lead time estimates, but

    constantly strive to improve their manufacturing process and reduce lead times.

    3)Inventory control is concerned with minimizing the total cost of inventory. In the U.K. the

    term often used is stock control. The three main factors in inventory control decision making

    process are:

    The cost of holding the stock (e.g., based on the interest rate). The cost of placing an order (e.g., for row material stocks) or the set-up cost of production. The cost of shortage, i.e., what is lost if the stock is insufficient to meet all demand.

    The third element is the most difficult to measure and is often handled by establishing a "service level"

    policy, e. g, certain percentage of demand will be met from stock without delay. The ABC classification

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    12/27

    system is to grouping items according to annual sales volume, in an attempt to identify the small

    number of items that will account for most of the sales volume and that are the most important ones to

    control for effective inventory

    ABC analysis categories-

    There are no fixed threshold for each class, different proportion can be applied based on

    objective and criteria. ABC Analysis is similar to the Pareto principle in that the 'A' items will

    typically account for a large proportion of the overall value but a small percentage of number of

    items. Example of ABC class are:

    A items 20% of the items accounts for 70% of the annual consumption value of the items. B items - 30% of the items accounts for 25% of the annual consumption value of the items. C items - 50% of the items accounts for 5% of the annual consumption value of the items.

    Another recommended breakdown of ABC classes-:

    1. "A" approximately 10% of items or 66.6% of value2. "B" approximately 20% of items or 23.3% of value3. "C" approximately 70% of items or 10.1% of value

    ABC Analysis in ERP package

    Major ERP packages (SAP, Oracle, etc.) have built in function of ABC analysis. User can execute

    ABC analysis based on user defined criteria and system apply ABC code to items (parts). See

    detail at external link.

    Example of the Application of Weighed Operation based on ABC class

    Actual distribution of ABC class in the electronics manufacturing company with 4051 active

    parts.

    Distribution of ABC class-

    ABC Class No. of Items Total Amount Required

    A 5 % 15 %

    B 10 % 15 %

    C 85 % 10 %

    TOTAL 100 %100

    Using this distribution of ABC class and change total number of the parts to 4000.

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    14/27

    Uniform Purchase:-When you apply equal purchasing policy to all 4000 components, example weekly

    delivery and re-order point (safety stock) of 2 week supply assuming that there are no lot size constraints,

    the factory will have 16000 delivery in 4 weeks and average inventory will be 2.5 week supply.

    Application of Weighed Purchasing condition-

    point of 2 weeks supply, A class weekly delivery with re-order point of 1 week supply, total number of

    delivery in 4 weeks will be (A 200 x 4=800) + (B 400 x 2=800) + (C 3400 x 1=3400)=5000 and average

    inventory will be (A 75% x 1.5weeks) + (B 15% x 3weeks) + (C 10% x 3.5weeks)=1.925 week supply.

    6)The new age mantras of any business today are the customer knows best and the

    customer is always right. Businesses have grown and fallen because of the all important

    customer. While the customer is king, and businesses are geared towards serving their

    customers in every way possible, without a good supplier or supplier chain to sustain the

    business, the customer base will fast disappear. Hence the key to running and managing a

    business successfully means that you have a strong customer base and a stronger supplier base.

    So how do you decide if a supplier is good and trustworthy? Before answering that, let us begin

    with first understanding what defines a good supplier.

    A good supplier is one who can meet all customer expectations, with respect to delivery time,

    quality of goods and dependability.

    Therefore it is logical to infer then that a good supplier is one who meets theses qualities.

    However while the laws of commerce have remained relatively simple, the demands and

    expectations of the customer keeps evolving. And hence the role of the supplier has changed as

    well. Keeping in mind the expectations of the customer, the following list contains seven key

    characteristics of a good supplier:

    Timely delivery: A good supplier is someone who keeps up to timely delivery of goods and

    supplies. Delayed supplies leads to business losses to the immediate customer and in turn

    delayed delivery to the end customer. This also opens up avenues for other secondary systems

    like buffer inventories to keep the chain going in addition to increasing overall costs.

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    17/27

    Constant frequency of delivery (daily basis): If a supplier can keep to supplying goods at

    constant and smaller frequencies, then the cost advantage is supplemented. Meaning, if a

    product or part is found to be defective, then the time spent in replacing it is minimal as

    opposed to having to replace a whole carton or shipment of that item since the delivery is

    frequent and the supply chain is actively functioning. This is not only cost effective but is also a

    time and space saver.

    Reasonable price: Business owners and suppliers add the cost of purchasing materials for a

    product into its retail price making it costlier. A reduction in this cost will lead to a reduction in

    the cost of the product as well.

    Minimal paper work: From the placing of an order to the actual buying of an order involves a

    ton of paper work. A good supplier will find ways of reducing the amount of paper work

    involved.

    Quick response/ turn around time: The world of business is highly unstable, and often the gap

    between demand and supply can be hard to predict. A good supplier will always be prepared to

    meet such a contingency. Again a frequent and smaller quantity of supplies is the key to

    eliminating this gap.

    Inspection of goods: Inspection of goods is a time consuming activity for both the supplier and

    the buyer. However quality assurance of the goods can again reduce the time spent on

    inspecting the goods.

  • 7/31/2019 Asssignment Ncp 24 & 25 OF NICMAR

    18/27

    Taking care of wear and tear and transport damage: Transportation and delivery often

    involves a lot of wear and tear and a good supplier is someone who recognizes these limitations

    and takes proactive steps to help reduce or avoid the damage involved. The importance of a

    good supplier cannot be undermined and it can be said then that a business is as good as its

    suppliers.
