Tender Estimation QS/15/40/16 Introduction This report has been written for Tender Estimate assignment in the 3rd semester. This report is mainly focused on study of the estimation in the construction industry. A Tender Estimate establishes the base line of the project cost at different stages of development of the project. A Tender Estimate at a given stage of project development represents a prediction provided by the cost engineer or estimator on the basis of available data. It is defined as that area of engineering practice where engineering judgment and experience are utilized in the application of scientific principles and techniques to the problem of Tender Estimate, cost control and profitability. The method of tender pricing process, the consideration while pricing, information required for pricing, factors affecting in making all in rates, preliminaries, suppliers quotation and the discount types are the main area covered in this report. Being the quantity surveyor, he is the one playing in monetary environment of the construction industry. The quantity surveyor mind is required not only for the estimating he will have to be able to forecast what will be happening in future. In estimating by means of norms any one can do or else computers can do. But the reason why still quantity surveyor is required he is going to analyze the situation where the adjustment to be made according to the situation. Those type of calculation have established. BTEC HND in Quantity Surveying Page 1 Tender Estimation QS/15/40/16 Acknowledgement I take this page to acknowledge most important people in my life. First and foremost I would like to gratefully acknowledge the enthusiastic Tender Estimation lecturer Mrs. Pabasara Kariyavasam of British College of Applied Studies (BCAS) for her valuable guidance and advice. She inspired us greatly to work in this project. Her willingness to motivate us contributed tremendously to this assignment. I would also like thank the authority of BCAS for providing us with a good environment and facilities to complete this module. Also, I take this opportunity to thank the Programme Manager Mr. Haseeb for offering this subject, Tender Estimation. This gave me a clear vision of what a Quantity Surveyor must do in future as his job. Finally, my honorable mention of thanks goes to my family and friends for their understandings and supports on me in completing this assignment. Without helps of the particular that I have mentioned above, I would face many difficulties while doing this assignment.

Decision making to computation Tender program information that requires in pricing other document to be submitted with the tender Collect necessary Pricing the tender Prepare Tender adjudication Tender Submission. Make the decision to accept tender application, this process initial step of a competitive tendering process in which qualified suppliers or contractors are invited to submit sealed bids for construction or for supply of specific and clearly defined goods or services during a specified time frame. Tender program –Contractor look at the tender to make a plan and sea that can activities enabling on time tender submission of tender. Collect necessary information that requires in pricing – In pricing contractor get the information about price lists, sent quotations and collect cost data about materials. Pricing the tender – Then use the information and start pricing the tender by building up unit rates, pricing the total BOQ and build up cost. Prepare other document to be submitted with the tender – Then contractor collect the document that need to submitted with the tender document like bid bond to requires value, method statements, work program, financial statements, previous work record, site organizations chart, site layout, sources of resources etc. Tender adjudication – However after contactor add mark-up percentage on to the cost and apply in BOQ to ready the tender document to submission. Tender Submission – After complete the pricing the BOQ, dully filled the form of tender, incorporate all necessary submittals specified in tender document, specially bid bond, submit the tender with required manner. And In order to prevent such a disaster, do not leave things to the last minute. Plan the process well and make sure that you allow for all potential problems, such as ensuring all files are safely stored and backed up and printers are working and have a sufficient stock of ink or toner. From above factors will influence in successful in tender submission. BTEC HND in Quantity Surveying Page 4 Tender Estimation QS/15/40/16 1.2. Identify the factors to be considered in pricing a tender Pricing a tender is a pricing construction operation usually spared throughout specified time period. cost of operation, therefore depend on some certainties and uncertainties as well behavior of these factors should be considered in conjunction with all aspects of the tender. finding from the examination of tender documents and information collected would be helpful in pricing the tender. The factors to be considered in pricing are; Types of contract – Lump Sum. Measure & Pay, Design and build Special condition or instruction given by client Price fluctuation Advance payment Payment structure Standard form of contract – SBD Form by ICTAD, FIDIC Construction period and maintenance period Location of site, Accessibility, Facilities available, Neighborhoods Nature of the workplace - weather, Ground condition Availability of material, Labour, Plant, Technology Construction methods Credit facilities from suppliers Stock of materials Sub contractors Method of measurement used in preparation of BOQ Imported materials BOI facilities BTEC HND in Quantity Surveying Page 5 Tender Estimation QS/15/40/16 Accommodation of workplace Rules and regulation-Local authorities, Government Taxes Extend of design information available Potential design changes by client Accuracy of the available cost data Competition in the market Estimator’s skill and estimation methods Tender validity period Description for some factors Payment of structure Since most construction companies are obtaining the capital from the bank loans. contractor has to know the payment structure from the client. Because client has to pay the bank loans payments and the interest as well. And the Progressive payments are a common billing procedure for construction projects, for instance. For example is a shipment that cannot be delivered all at once. The client is served by not having to pay an unaffordable payment up front, and by having a tool to keep workers motivated to complete the project. The project manager is served by having ability to pay worker wages and buy materials. We must conformed the payment dates. Location of Site, Accessibility, Facilities Available, Neighborhood The site at which the construction is carried out has a mass outcome on the cost. It is so, depending on where site is situated. So transport facilities, labor agencies, security services, local services like water, electricity are available or not. and neighborhood, if it is a residential area, work will not be allowed to be carried out at night time due to the noise. If there is a school, work shall have to start after school hours. BTEC HND in Quantity Surveying Page 6 Tender Estimation QS/15/40/16 Type of contract A construction contract is the warranty that the executed job will receive the specific amount of compensation or how the compensation will be distributed. There are a several types of construction contracts used in the industry, but there are certain types of construction contracts preferred by construction professionals. Construction contract types are usually defined; by the way, the disbursement is going to be made and specifies other specific terms, like duration, quality, specifications and several other items. So we should read the specification and drawing and decide the best contractor. BTEC HND in Quantity Surveying Page 7 Tender Estimation QS/15/40/16 1.3. Identify the sources and nature of information required for cost estimating Cost Estimate We need to considerations two primary factors when planning the project: budget and time. Cost estimates are necessary for accurate budget projections, which should eliminate most over runs. Human Resource Plan The information in the human resource plan useful for estimating costs includes the list of roles and responsibilities, personnel rates, and recognitions and rewards. Project Schedule An approved project schedule will give you the information about the resources needed to complete the project work. This information is crucial to make cost estimates. As you learned in the previous chapter, activity resources are estimated by performing the Estimate Activity Resources process. Therefore, the Estimate Costs process should be closely coordinated with the Estimate Activity Resources process, which in turn depends on the Estimate Activity Durations process because activity duration is determined for the given resources. Scope Baseline All three components of the scope baseline; scope statement, WBS, and WBS dictionary are useful in estimating the project cost. The scope statement will provide the costrelevant information, such as project and product acceptance criteria, assumptions and constraints, product description, key deliverables, and project boundaries around the scope. Enterprise Environmental Factors Enterprise environmental factors relevant to estimating costs include market conditions and published commercial information that will provide the cost of resources, including human resources, materials, and equipment. This will also provide the information BTEC HND in Quantity Surveying Page 8 Tender Estimation QS/15/40/16 related to the availability of products and services and their cost and rates. Supply and demand conditions can also influence the project cost. Organizational Process Assets This includes the organization's policies regarding cost estimates, cost estimating templates, and information from previous projects, including lessons learned. There are four common types of cost estimates are: Planning estimate: a rough approximation of cost within a reasonable range of values, prepared for information purposes only. Budget estimate: an approximation based on well-defined but preliminary cost data and Firm estimate: a figure based on cost data sound enough for entering into a binding contract. BTEC HND in Quantity Surveying Page 9 Tender Estimation QS/15/40/16 Task 02 Prepare standard rates for labour, construction plant and materials 2.1 Identify the factor to be considered when calculate all in rates labor, plants and material When calculating all in rates for labours Need to see the thing more than salary of a labor to find the all-in rate of labor but is apply for pavement labors only. Number of weeks or days per year Working hours Annual holidays per year Sick leaves per year Public holidays per year Inclement weather details Basic wage EPF, ETF Insurance scheme Tool money Accommodation Bonus Allowance Over time Extra payment for special skills When calculating all in rates for materials Transportation cost Purchased cost Transportation cost Distance to the site Residue wastage Quantity Unskilled hourly wage Discount Loading and unloading BTEC HND in Quantity Surveying Page 10 Tender Estimation QS/15/40/16 When calculating all in rates for plant Purchased price in plant Scarp value Repair and maintenance cost License and insurance Fuel usage details Lubricant usage details Operator cost Tire cost and life time Transport cost to site Deprivation Working hours Taxes BTEC HND in Quantity Surveying Page 11 Tender Estimation QS/15/40/16 Task 2.2 Calculate all in rate for the provided items. 1.

Preliminaries The first sectional bill in a BOQ is preliminaries bill. Preliminaries are not included in the measured work items. But these items are necessary to carry out the measure work items. Preliminaries can be classified into two parts like fixed charges and time related charges. The cost of fixed charges are to be considered independent of duration of use. But time related charges are defined as works where the cost of which is to be considered as dependent on duration. The more the duration the more the cost. These make an important place in determining the cost of project. And this may vary from contractor to contractor. Some of the preliminaries are : List of drawing and other documents. Setting out for the work. Provision for performance bond. Temporary roads. Take necessary preservations. Sanitary and accommodation for employers. All risk insurance. Payment for local authorities. Provision for progress chart. Boards and signs Scaffoldings Site office, stores and vehicle yards Provision for first aid. Maintenance for public road. Temporary fencing Site safety Final clearance. Water for work BTEC HND in Quantity Surveying Page 16 Tender Estimation QS/15/40/16 Electricity for site activities Overhead cost Besides the “construction items” which have been priced (labor, plant & materials), the other items need to be priced in order to ascertain the tender price is overhead costs of the company. This is the most certain & easiest to estimate costs of all the costs. However, they causes more problems than any other costs. The definition for overhead cost is: Costs that support the production process in a Project but are not directly related to the production process (do not occur on site). Relate to off-site costs which must be recovered to maintain the head office & local office facilities. Company overheads can be two types indirect and general. Further classifications can seen through the diagram below. Fig.1.Flowchart of company overheads BTEC HND in Quantity Surveying Page 17 Tender Estimation QS/15/40/16 Indirect expenses (Project Overheads) Vary with & are caused directly by individual jobs but are not directly chargeable against specific phase of work. Example of project over heads are : Welfare fund payments, apprentice training, social security, workmen’s compensation, unemployment taxes, miscellaneous payroll - related expenses, direct supervisions, building permits, temporary buildings, sales taxes etc., Site staff salaries, Maintenance of site vehicle, Equipment’s for site office, Furniture for site office, Site stationeries, Site welfare facilities etc., Site services, Office furniture etc. Either added as percentage of estimated direct job costs - Suitable for contractors who perform same type of work all time, with stable work load. Normally expressed as overhead percentage of turnover. Company policy to be clearly understood Affected by market - Bad market conditions – scarce work, turnover drops General Overheads (Head office overheads) Can’t be charged directly to single job. Examples of such cost are:o Costs of maintaining office, rent, telephone, property taxes, interest, insurance, marketing material, office equipment; depreciation, salaries & cost of employment of directors & staff; Printing, stationery, postage & telephone; cars & other vehicle costs for office staff; advertising & entertainment; Finance cost & professional fees, Salaries and costs to employ directors and staff, Rental fees, rates and maintenance of office, stores and yards, Fuel and power charges, Cars and other vehicles cost for office staff, Solicitor fee, Office security, Consultancy fee, Welfare and medical facilities Contractors often think that overhead costs can be reduced by reducing prices on jobs. Very dangerous – overhead costs can only be reduced in the office. Reducing the price bid for a job cuts profit – not overheads. Price cuts come off the top – out of profits – while overheads go on forever. BTEC HND in Quantity Surveying Page 18 Tender Estimation QS/15/40/16 How the overheads are included in the project’s cost Either added as percentage of estimated direct job costs o Suitable for contractors who perform same type of work all time, with stable work load. Detailed separately in tender. o Cost identified and attributed directly to certain job (i.e. component of unit rate) o Varying workloads, different type of jobs. o % add‐on simply adds another element of uncertainty. Necessary to distribute overheads against each project currently involved in, in an equitable manner. Generally larger projects receive a larger percentage of overheads. Once annual overheads have been recovered, you can reduce costs or even omit from new projects.

Trade Discount vs. Cash Discount Discounts are a reduction on the price of the goods or services that are provided by the seller to the buyer. Discounts result in the buyer having to pay an amount less than the listed price for the products, and such discounts are usually offered for to encourage customers to purchase more of the company’s products or to ensure faster payment. The article discusses two types of discounts; trade discounts and cash discounts and explains how these two types of discounts are quite different to one another. Trade Discount A trade discount is an incentive provided to a customer to purchase more of a product. There are many types of trade discounts that include discounts for purchasing goods in bulk, discounts provided for new customers, discounts for customers that purchase goods repeatedly, year-end discounts, etc. The aim of offering a trade discount is to encourage the buyer to purchase a larger quantity. Trade discounts maybe offered as a dollar amount reduction from the quoted price or may be provided in the form of a percentage reduction. The trade discount offered will increase in size with the quantity of goods that are purchased; higher discounts are offered for a larger volume of purchases. The trade discount that is offered to one vendor may be different to another since the discount will depend on the type of goods and quantity purchased. Trade discounts cannot be recorded in accounting books. Instead, they are recorded as revenue (the amount that was provided as a discount will be reduced from total revenue). Ex: 1000 Birck @10 =10000 Discount5%= 10000x5/100 =500 Supplier code to contract Rs.10000 after give discount 5% so main contractor have to pay only Rs. 9500 BTEC HND in Quantity Surveying Page 23 Tender Estimation QS/15/40/16 Cash Discount Cash discounts are provided to customers either when a customer pays an invoice with a specific period of time, or when the customer makes a cash payment to the seller instead of using checks or credit cards. Cash discounts are stated in contractual agreements and are used to reward customers to make early payments on their invoice. This discount maybe printed on the invoice itself, and once the seller issues the invoice with a standard payment period of 30 days customers can refer to the discount details on their invoice and see how much of the total amount can be saved as a discount when early payments are made. Cash discounts are also used frequently for customers that pay cash instead of using credit cards. For example, gas stations offer discounts on the price for customers who pay in cash since gas stations can save on credit card processing fees when customers pay in cash. Ex: Total sub-contractor price=1000000 Discount5%= 10000x5/100 =50000 Sub-contractor price Rs.1000000 after give discount 5% so main contractor have to pay only Rs. 950000 What is the difference between Trade Discount and Cash Discount? Trade discounts and cash discounts are similar to each other in that they are both offered by the seller to the purchaser, and they both reduce the final amount that needs to be paid. The aim of a trade discount is to encourage customers to purchase a higher volume of the company’s product. The aim of a cash discount is to encourage the buyer to settle the invoice within a specific period of time, also for cash payments, instead of using checks or credit cards. While a trade discount is provided on the purchase of goods, a cash discount is provided at the time the payment on the invoice is made. BTEC HND in Quantity Surveying Page 24 Tender Estimation QS/15/40/16 Summary: Trade Discount vs Cash Discount A trade discount is an incentive provided to a customer to purchase more of a product. Cash discounts are provided to customers either when a customer pays an invoice within a specific period of time, or when the customer makes a cash payment to the seller instead of using checks or credit cards. A trade discount is provided on the purchase of goods, and a cash discount is provided at the time the payment on the invoice is made.
