Examining Life Cycle Costing Engineering Essay

Life Circuit Costing (LCC) is a method to establish the full total cost of possession. The total costs of possession are machinery and equipment, including its cost of acquisition, procedure, maintenance, change, and/or decommission (SAE 1999). Besides, this is a structured approach that addresses all the elements of this cost and may be used to produce a spend account of the product or services over its expected life-span. Common terms used to describe the consideration of all costs as associated with a built property throughout its life time are called Life Circuit Costs (LCC), Whole Life Costs (WLC), Cost-in-use and etc.

As Flanagan and Norman (1983) have defined the Life Routine Costing of a secured asset is the total cost of this asset over its operating life, including the original acquisition costs and following running costs. Another Life Cycle Costing described by Hoar and Norman is Life Cycle Cost of an asset as today's value of the full total cost of the asset over its operating life including initial capital cost, occupation costs, functioning costs and the cost or benefit of the eventual disposal of the asset at end of its life.

The cost planning is importance for a building project, if the price planning can't be effective unless the full total costs are believed. For example, both of the initial cost and future cost and using the present value and some formulation to determined. In a very constraint, the "Real Cost" should encompass the original acquisition costs and the operating costs of retaining costs of retaining and operating a building throughout its effective life include refurbishment.

Life Cycle Costs is make reference to as ultimate life cost or total cost, a method of cost prediction where the original constructional and associated costs and the annual jogging and maintenance costs of any building, or part of the building, can be reduced to a common measure. As a summary Life Cycle costing is an preliminary cost plus maintenance cost and planting cost.

2. 1. 2 Aspect of Life Routine Costing

Life Cycle costing is utilized as a design tool for the assessment of the expense of different design, materials, components and constructional techniques. Besides, it is a valuable guide to the custom in obtaining value for money for construction job client. Inside the construction project the life span Cycle costing normally is utilized by property professionals or designers to compare costs against the worthiness accruing from future rents for any aspect or part in development works.

The perform of the life span Circuit Costs can be allows building functions to be portrayed in terms of the expenses of repairing and renewing the finishing and fittings, lighting and servicing and of the labour needed in working the building. Besides, it can also be permit the huge selection of factors on which judgment is necessary to be reduced to an evaluation of an individual cost with the non-public assessment of the worthiness of the building.

Life Pattern Cost also known as Whole Life Costs is include thought some factors when making and specifying. The first factor is preliminary or procurement costs, including design, structure or installation, purchase or leasing, fees and charges. Second factor as future cost of operation, maintenance and repairs, including management costs such as cleaning, energy costs and etc. Third factor is future substitution costs, which including loss of revenue because of the non-availability. Fourth factor is future alteration and adaption costs, lack of revenue due to the non-availability. The fifth or previous factor is future demolition or recycling costs.

Whole Life Costs can be carried out at any stage of the task and not only during the procurement process. The potential of its biggest success is during procurement because of; make reference to the (Shape 2. 1) as below:

All the costs in the life span Pattern can be changed into present value (PV) by discounting techniques which makes it possible to combine all the expenses of the building. In perform of Life Routine, it will provide rationale for choice in circumstances where there are different means for achieving a giving thing. In any financial appraisal you need to not disregard the inevitable future maintenance costs essential for a building to perform its complete function. The expense of maintenance must have an impact on the true economic worth of your building in use.

The relative importance of first and working costs is inspired by financial interest of the client. A developer will not usually consider the running costs, for an industrialist will certainly influenced by the higher tax savings accessible for operating costs. Besides, an occupier could be more concerned with the total effect of the design upon the costs of owning and working the building.

2. 1. 3 Why Life Pattern Costing is very important?

The visible costs of any purchase represent only a tiny proportion of the full total cost of ownership. In many departments, the duty for acquisition cost and following support money are held by different areas and, subsequently, there is little if any incentive to use the concepts of LCC to purchasing insurance plan. Therefore, the application of LCC does have a management implication because purchasing systems are unlikely to apply the rigours of LCC evaluation unless they start to see the benefit resulting from their efforts.

There are some major advantages of using Life Cycle Cost research.

Life Cycle Cost Research is gives an emphasis on a complete or total cost approach undertaken during the acquisition of a capital cost job or asset, alternatively than merely concentrating on the original capital cost only. In another words we can said Life Pattern Cost can be better awareness of total costs, the application form provides management with an improved awareness of the factors that drive costs and the resources required by the purchase. It's important that the price effective regions of the purchase. Also, awareness of the price drives will also identify areas in existing goods that would benefit from management participation.

Life Cycle Cost technique wills more exact forecasting of cost profile, the application of Life Pattern Cost techniques allows the full cost associated with a procurement to be believed more accurately. It contributes to upgraded decision making whatsoever levels, for example major investment decisions, or the establishment of affordable support policies. Additionally, Life Pattern Cost analysis allows more accurate forecasting of future expenditure to be applied to long-term costing diagnosis. For example, it will take into account the original capital costs, repairs, running and replacement costs and expresses these in comparable terms.

Benefit of evaluation of contending options in purchasing, Life Circuit cost is a technique allow for evaluation of rivalling proposal based on through life costs and the life span Cycle Cost examination is another to the majority of the service agreements and equipment purchasing decision. It is also a secured asset management tool which allows the operating costs of premises to be evaluated at repeated intervals.

Last benefits of Life Pattern Cost analysis is the performance will be trade-off against cost. In the purchasing decision cost is not the only real factor to be considered when assessing your options. There are other factors such as the overall fit against the necessity and the quality of the products and the levels of services to be provide. Life Cycle Cost analysis permits an expense trade-off to be produced against the differing qualities of the purchasing options.

Whilst there has been an emphasis after the use of Life Cycle Costing during the pre-contract period, its use can be increasing throughout every period of the building's life, as follows:

At inception. Life Circuit Costing can be used as an element part of investment appraisal. The approach is utilized to balance the associated costs of building and maintenance with income or rental values.

During the look stage. It is to evaluate the different design options to be able to determine their economical impact throughout the project's life. It really is frequently used alongside value management and other similar techniques. The approach focuses on those areas where financial benefits may be accomplished.

During the engineering stage. In this phase there are many different areas that may be considered for its application. It can be applied to the contractor's engineering methods, which can come with an influence upon the timing of cash moves and hence the time value of such repayments. The contractor is able to apply the rules to the purchase, lease or employ the service of of the construction place and equipment. Development managers and companies' surveyors have the ability to offer an input to the scrutiny of the design, if engaged sufficiently early in the project's life to be able to identify very existence cost implications of the design, manufacture and engineering process.

During the project's use and profession. It really is a physical asset management tool. Costs-in-use do not stay even or static throughout a project's life, and for that reason need to be reviewed at frequent intervals to determine their implications. Taxation rates and allowances will change and have an influence upon the facilities management guidelines getting used.

At procurement. The idea of the lowest sensitive bet price should be changed in the framework of whole life costing. Beneath the present contractual and procurement plans, manufacturers and suppliers are encouraged to supply goods, materials and components which ensure their lowest primary cost, often irrespective of their future cost-in-use. It is now accepted by many clients a larger emphasis should be placed upon the overall monetary performance of different components.

In energy saving. Expereince of living costing can be an appropriate strategy to be used in the energy audit of premises. The energy audit takes a detailed analysis and analysis of the premises, saving of outputs and other data, tariff documents and appropriate monitoring systems.

2. 1. 4 Problems in Assessing Life Cycle Costs

There are some difficulties when assessing the life span Cycle Costs approach. The first difficulty of effectively is when evaluating including the maintenance costs and working costs of different materials, procedures and systems in the buildings. Sometime for the person who has less experience, they will send the historical cost data to assess. The fantastic scarcity of reliable historical cost data and predicting the lives of materials and components is often fraught with dangers.

In engineering team, the quantity surveyor will rely by himself understanding of the materials or component or possibly on manufacturer's data regarding relatively services. For instance, for the coloring show modifications and are influenced by kind of paint, variety of coats, condition of platform and level of preparation, amount of subjection and atmospheric conditions, it is barely to estimate the Life Cycle Cost for the factor.

The difficulties will appear also be based upon the individual. Owners' and occupiers' maintenance produces could also vary considerably. They could can wait or didn't not follow the specific plan to do maintenance activity which prepared by the manufacturer's technical specs. In the other hands, the types of payments will be calculated by initial, twelve-monthly and periodic requires knowledge of discounted cash techniques. For example, determined for the maintenance cost for elevator, need to using the near future cost changes into prevent value.

Besides, the federal government tax has bearing on maintenance costs and needs account. Selection of suitable interest levels for calculations regarding periods of up to sixty years is incredibly difficult.

Where projects should be sold as an investment on completion, your client may show little fascination with securing cost savings in maintenance and working costs. Where in fact the initial funds available to your client are severely restricted, or his involvement in the project is of quite short-term duration, little result that he can save large sums in the foreseeable future by spending more on the original construction.

Future costs can be damaged by changes of tastes and fashion, changing statutory requirements for the structures and the substitute of worn out components by superior updated items. Lives of different types of properties are difficult to forecast with correctness.

Practical Problems Which Affect Life Cycle Costing

Life Cycle costing study is to prepare a cashflow schedule for the building including all different user costs as they happen throughout the building's life. besides, its about time consumed for the requirement of the life span and maintenance information for the components and materials that need to be prepared.

Lives of creating components can be forecasted on the basis of observed scored of inability for existing structures. However, it often shows large differences in the maintenance profiles of relatively similar buildings.

Life Cycle Cost the key weakness is the top proportion of the development techniques and components in an average modern building and the gathered data becomes out of date or is no more appropriate as new components and materials are unveiled and perhaps more progressive designs produced.

Realistic life cycle costing profiles are extremely difficult to prepare. Many predictions and assumptions are of questionable validity. Changes in the basic prices of materials, components, labour and capital are difficult to forecast with reliability and will impact all individual costs.

Sophisticated cost models making use of many assumptions can be rendered invalid by changes in basic prices, unlikely to be homogeneous across different components. Changes in government policy have significant results on future needs and costs.

Social, monetary and technical changes are destined to have significant effect on the costs incurred throughout a building's life and are all unpredictable at the time of preparing the life span cycle priced at plan.

Emergency vehicle repairs and maintenance, arising from unforeseeable design faults or bad workmanship, constitute a significant proportion of maintenance costs, display a random routine in both timing and scope, associated disruption costs can only be assessed in an exceedingly approximate form. Foreseeable maintenance work such as cleaning and redecoration, the actual decision as to the timing of the work depends to a considerable amount on management policy.

Redecoration cycles vary significantly to meet changing tastes and styles, to implement a fresh colour pallette or on an urgent change of occupancy. Besides, the longer cycles can result from financial constraints leading to deferment of the repainting and increasing significantly the cost the eventual work.

2. 2 Hydraulic Elevator

2. 2. 1 Introduction

In the modern sense, an elevator is defined as a conveyance designed to lift people and material vertically. The conveyance should include a device to avoid it from falling in the event the lifting means or linkage fails. Elevators with such safety devices did not are present until 1853 when Elisha Graves Otis invented the elevator safety device.

Elevator is the approach of making use of the available elevator technology to fulfill the traffic demands in multiple and one purpose multi-floor properties. Elevator in the present day sense, is the procedure of applying elevators and the building interfaces essential for the vertical transportation of workers and material within structures. Services should be provided in the bare minimum practical time and equipment should take up at the least the building's space.

2. 2. 2 Benefit

Hydraulic elevator is common chosen by the client who using low climb building. It is cheaper to create, install and service, and since it has a decidedly better safety record than the other type of elevator, such as electric elevator. For the areas being contain the earthquake, hydraulic elevator has proven itself to be evidently the safer option, due to the threat shown by swinging counterweights and also because the automobile is suspended from the top of the hoist way. The amount below was show that the comparability for the way the construction basic safety perform in electric elevator and hydraulic elevator took place fire or earthquake.

Figure 2. 2 Electric Elevator and Hydraulic Elevator

Hydraulic elevator's jack assembly, by necessity, is located below the lowest floor. The jack is located in a casing, and while it will resist damage from smaller amounts of normal water seepage, total inundation by floodwaters will usually result in contamination of the hydraulic petrol and possible damage to the cylinders and seals of the jack. Salt drinking water can make it corrosive and can particularly damaging the hydraulic elevator. The hydraulic pump and reservoirs of the hydraulic elevator are also vunerable to water damage, nonetheless they may easily be located up to two floor surfaces above the jack as shown in Amount 2. 3 Float and Control Device to Control Cab Descent.

Figure 2. 3 Float and Control Device to Control Cab Descent

Some equipment common to all elevators will be ruined by flood waters unless guarded. The most obvious examples are the elevator cab. Depending upon the size of the cab and the types of interior materials used, a cab may cost between S5, 000 and S50, 000. Overflow harm, which can range between superficial to almost a complete reduction, can certainly be prevented by keeping the cab above floodwaters.

A hydraulic systems is they can simply increase the relatively weakened drive of the pump to create the stronger drive needed to lift the elevator car.

2. 2. 3 Negatives for Hydraulic Elevator

The problem is the size of the equipment. For the elevator car to be able to reach higher flooring surfaces, you have to make the piston longer. The cylinder needs to be a little bit longer than the piston, of course, because the piston needs to be able to collapse all the way when the car is at underneath floor. In short, more stories signify an extended cylinder. The issue is that the whole cylinder composition must be buried below underneath elevator stop. This means you have to dig deeper as you build higher. This is an expensive task with buildings on the few stories large. To set up a hydraulic elevator in a 10-account building, for example, you would need to dig at least nine reviews deep.

A hydraulic elevator is that they're fairly inefficient. It requires a whole lot of energy to raise an elevator car several stories, and in a standard hydraulic elevator, there is no way to store this energy. The power of position (potential energy) only works to motivate the fluid back to the reservoir. To improve the elevator car again, the hydraulic system has to generate the power yet again. The rope elevator design gets around both these problems.

2. 2. 4 Hydraulic Elevator Impact

Actually for just about any type of elevator system gets the maintenance requirements in its life routine. The maintenance cost is expensive for the owner, so that need to understanding the type and options that will always make elevator breakdowns or make the elevator should do repair works. For being discovers the most cost-effective ways for the owner is to keep carefully the elevator carrying out well and decrease the downtime and repair cost.

One of the most common, expensive and aggravating problems that always make the elevator malfunction is vandalism. The vandalism can demolish the appearance and hinder the operation of the elevator, even compromise safety of the elevator. While to prevent the vandalism in elevators can set up vandal-resistant interior and control panels in elevator cabs and making certain elevators are operating successfully. Besides, long wait times and long travel times will produce irritation that causes vandalism also.

Elevators operating defectively in an ailment of long wait time and long travel and there will be the warnings that the elevator control system is expanding problems. Average hold out times and elevator speed should be check and record frequently, for an example inspection make by every half a year. The inspection by compare enough time spent for waiting an elevator during optimum and off-peak cycles to set up a baseline or to the manufacturer's standards for such type of program of elevator. The age and overall condition of the elevator may cause with a mulfaction, for example faulty relay or problems appears will influence to be long put it off time and poor performance for an elevator.

Another one of the common causes of elevator malfunctions is overheating for the elevator's drive and control system. The elevator equipment found in places of the environmental conditions aren't ideal then the challenge will continually accrue. Hydraulic elevator control system is positioned in a specific basement area with little or even no ventilation or legislation of humidity, in other words not in a good environmental conditions. The heat should come from hydraulic pumps and solid-state adjustments during high-use period can easily make the room conditions to be increase to the stage where components overheat. The ways to avoid overheating can be use a dedicated coolant system. It is using the completely recirculated air which system can regulate both temperatures and wetness levels while keeping dirt and grime and dust particles out. Besides, if there have any existing ventilation louvers, entrances and other opportunities need to properly sealed when installing the machine.

Now a day the class of elevator is increasing, the power factor to be nervous about the problem of old elevators have the low power factor. Electric power factor is importance, as a result of way utilities invoice customers to be impose a penalty in the form of higher rates in the matter of low power factor. The higher of the magnetizing current, then the less circuit's capacity to provide current that does create a useful work. Low vitality factor can be result in the overloading circuits and needing to upgrade the system electricity lines.

Quality of electricity is delicate to buildings that happen to be filled up with computerized equipment. Interfere with the equipment or cause damage by any adjustment to the system voltage or the condition of the influx form of the alternating current. Common to the old elevator systems which using the motor generator packages, it factors behind the harmonic distortion to voltage and the current waveforms. These distortions are generated incidentally when the elevator drive uses vitality from the machine supplying it and harmonic distortions can disrupt the operation of sensitive electronic equipment. Besides, it can have problems with overheating, resulting in early failing when other motors are connected to the circuit.

Comprehensive planned maintenance program is importance to reduce the elevator breakdowns. The planned maintenance can eliminate many common problems for example like improper door procedure, inaccurate stopping and inoperative safeness devices. Inside the maintenance contract, need selection of coverage to be large, from the essential breakdown repair to full-service agreements including insurance against automobile accident claims. The agreement should need to include all the maintenance activities recommended by the manufacturer and all safety assessment required by the neighborhood jurisdiction and by the product manufacturer. The lowest cost of contract generally imply by fewer labour hours spent keeping or fewer parts being substituted, and fewer part to be maintenance, so it will result in the ore higher overall costs due to the faster deterioration of elevator components.

2. 3 Life Cycle Cost of Hydraulic Elevator

2. 3. 1 Introduction

Cost efficiency is a key component of designs and system with improved long-term performance. Life cycle cost analysis not only considers the "first costs" of any elevator, but also the long-term costs, including resources, functions, and maintenance. The guideline for Life Cycle Cost evaluation help the job teams assess the maintenance costs and procedure costs and used them to see planning, design, and construction decisions.

Life Routine Cost Analysis is a cost-based process, its goal is to recognize the most cost-efficient building design and development strategies over the life of the property. Life Cycle Cost Examination addresses values that can be stated in us dollars, not subject matter issues such as occupant comfort or environmental impact. The most cost-effective solution is not necessarily the most environmentally ideal choice. For example, a building system might consume very little energy but cost more than it will save you in energy costs. However, careful design choices that result in efficient use of energy and water often do produce long-term cost benefits.

Life Routine Cost examination is a way of evaluating the cost-effectiveness of job design decision. Life Circuit Cost analysis is comprehensive since it properly makes up about many task cost variables. Included in these are a wide variety of project costs, which include the engineering costs, working costs, maintenance costs, replacement unit costs, utilities and others. In addition they encompass the time value of money, including a project-specific discount rate, inflation, and cost escalations for a number of goods services.

The Life Cycle Cost research process or review involves to establishing aims for the examination, to deciding the requirements for assessing alternatives, to discovering and developing design alternatives, gathering cost information, and developing a life routine cost for every alternative.

According to the principles of Life Routine Costing, the expense of ownership of any elevator is incurred throughout is very existence and will not occur at the point of acquisition. The shape below give a good example of a spend account showing how the costs vary with the time.

In some circumstances the removal cost will be negative because the item will have a resale value whilst for other procurements the removal, termination or replacing cost is extremely high and must be studied into consideration at the look stage.

2. 3. 2 Original Cost

Initial cost, sometime known as task cost or first costs, include both "hard" or construction costs and "soft" costs. The "hard" costs which include the labour costs, materials cost, equipment costs, furnishing costs and others. For the "soft" cost including the design fees, permit fees and more. Costs estimates and information from service provider, vendors and design groups may be used to develop project costs for Life Routine Cost examination alternatives.

In the Life Cycle Cost evaluation studies, the cost variations between alternatives are usually what is important, not the definite costs. The original costs just need to be developed for the components that differ between alternatives, all costs change must be captured to make a valid contrast. Design and other smooth costs should be determined and included in the Life Circuit Cost analysis calculations.

In providing services for a building there must be two cost concerns. One is the price tag on the initial building and the second is the go back from investment above the economic life of the building.

In elevatoring any building the cost-return factors start with the initial ideas. Many factors exterior to the building itself set up the criteria. It's very seldom that land is endless and that any type of building, low-rise or high-rise, can be chosen for confirmed site. Zoning rules must be complied with and the limitations of land use on a specific plot must be related to the building level. In areas where land use may be unrestricted, needs for auto parking and access to parking must be looked at. The cost of walking long horizontal ranges, in terms of your time consumed, should be compared with vertical travel by elevator.

In formulating the initial plans the foregoing alternatives are usually considered. As with any plan, the approaches taken may represent compromises since there is often more than one way to solve any problem. In elevatoring a building the ultimate result will generally be one of bargain between requirements of preliminary cost, space usage, service quality, and passenger-time-conservation.

2. 2. 3 Operating Cost

The functioning cost for hydraulic elevator can be viewed as as tool costs or the energy costs. For each types of energy service there's a cost per product of energy sent which will be billed to the building by regular or other specific period. The rates and models for these resources are listed below under the Life Cycle Cost Guidelines.

Energy estimating methods, usually the mechanical and/ or electric engineers over a design team will estimate the amount and rate of creating use. Essentially the most comprehensive and widely used method of doing these estimates included detailed hourly computer simulation of creating operations.

2. 2. 4 Maintenance Cost

Once an elevator is installed and operating, periodic maintenance is necessary, and, as its use goes on, replacement of putting on parts. Maintenance, which consists of ensuring the elevator is properly lubricated and operating, should take places as often as weekly in a heavily used set up, and less than monthly in a gently used service.

Replacement of minimal using parts such as deals on controllers is part of regular maintenance, and major replacements such as exchanging wire ropes will need to be done at periods from 8 to a decade, depending upon the utilization, condition, and design of elevator. Failures like the burnout of an electric motor, a bearing inability, or other repair items have to be corrected as needed.

Practically all elevator manufacturers give you a maintenance deal to provide maintenance treatment and needed alternative of their equipment. This manufacturer's maintenance comes in several varieties, the most attractive and highest listed being called full maintenance.

Elevator maintenance is billed at a monthly rate. The elevator companies depend on sufficient maintenance business each year to write off the price and also to make a go back on their investment in tools, manpower, inventory, training, and everything the incidentals to do business. There is absolutely no reserve built up to pay next year's expenditures. If one building does not require major replacement this season, it partially will pay for some other building that will. This approach suggests that if there is a tax benefits to building up a reserve for future replacements for a business, it could pay to set up with the elevator maintenance company to just purchase labour expended and keep maintaining a listing of needed parts and purchase major fixes as required.

Maintenance contracts should include the costs of making safety and operational teats as may be required by governmental and insurance agencies. They do not include the price tag on making any changes to the gear either anticipated to obsolescence or as may be required by new laws, like the addition of your life-safety system. The rapid progress in elevator design and the changing flavor in architectural treatment can result in the necessity to completely modernize elevators at age 20 to 25 years. In fact, many buildings getting close to time 50 are considering their second era of elevator modernization.

Maintenance refers to the expenses incurred to keep building systems jogging properly. Maintenance cost was get into four cost categories, which is preventive, reactive, organized, and deferred. These data should be predicated on historical data provided by facilities procedures.

Preventive Maintenance

For the precautionary maintenance is boring, scheduled activity designed to keep something jogging at its best. This maintenance is conducted whether or not there are any issues with a system. It is made to prevent break-downs. Changing filter systems and lubricating bearings are types of precautionary maintenance activities.

Preventive maintenance costs associated with equipment and systems should be contained into Life Circuit Cost analysis computations.

Reactive Maintenance

Reactive maintenance is conducted in response to problems. If the supporter belt breaks, for example, a technician issues a work order to replace the belt and address any associated damage to get the machine running again.

Reactive maintenance is unpredictable. Theoretically, if systems are running smoothly and everything required preventive maintenance is performed, then reactive maintenance should be minimal. In practice, unplanned failures will arise and can require fixes.

For a job to retrofit an existing building that has ongoing reactive maintenance needs, the Life Cycle Cost examination base case will include these costs, and the alternative can model sensible and appropriate reductions.

Planned Maintenance

Planned maintenance is to make reference to larger-scale maintenance that's not addressed under precautionary maintenance. Planned maintenance is the replacing of building subsystems at the end with their useful lives.

Life Cycle Cost analysis calculations expressly include organized maintenance by means of replacing costs of equipment and systems. For instance, if enough time frame of a study is 30 years and an element of a mechanical system needs to be replaced every a decade, then the life routine cost need to include the price tag on that replacement at 12 months 10, year 20, and year 30.

Factoring system a component replacing costs into Life Cycle Cost analysis computations requires making a number of assumptions about the useful life of the items. These assumptions should be plainly stated and documented in order to be established by the correct participants of the job team. Where possible, building component replacing frequencies should be constant with those in the Annual Investment in Vegetable Assets evaluation performed as part of the total annual budget plan. For instance, the general direction predicated on that research for the elevators and conveying systems the common life cycle is 25 years.

Deferred Maintenance

Deferred maintenance signifies a backlog of prepared maintenance. It is to keep deferred maintenance to the very least, but at present deferred maintenance does can be found. Deferred maintenance is not considered in Life Cycle Cost analysis for new building. For renovation jobs, the deferred maintenance costs can be included in the base case. It ought to be addressed as appropriate for alternatives that reduce these maintenance needs in different ways, such as system or component substitution.

2. 2. 5 Other Relevant Costs

Service Costs

Services costs include items such as janitorial services, pest control, and elevator maintenance. Since these costs depend more on the programmatic elements of a building than on the structures, systems, and other components, they are typically not considered in Life Routine Cost analysis. However, they must be include if for some reason they differ among the design alternatives.

Remodeling Costs

Remodeling costs may or might not be use in Life Circuit Costs analysis, depending on specific building program. Typically they aren't include, but some systems or components specifically require them. It really is within the task team's discretion to choose whether and how to fully capture these costs.

End-of-Life Costs

Residual Value is made up in the end-of-life costs, suppose all building have zero residual value by the end of the study life. this assumption may change in the future, but in the interest of keeping the original Life Circuit Cost analysis studies as easy as possible, it'll be used consistently across studies.

In the other hands, demolition usually this cost is assigned to new task on a site. When the extent or character of the required demolition varies among alternatives, it is suitable to add these costs. For the hydraulic elevator will making use of this demolition can be when it was took place vandalism, who owns the elevator need to determined the expenses of demolition repair all the looks breakdown.
