3 Construction Price Survey Form 1. Form Survey respondent Country Date survey completed:.. Currency: Name:... Age:.. Qualification:... Employer:.... Position Type of employer: contractor consultant academic research.. Contact details: government.. other Telephone no:.. address:... [If there is more than one respondent, each should complete a separate form and indicate below thescope of their response.] The prices in this survey are relevant to: o Types of construction work: All/ Residential building/ Non-residential building/ civil engineering work o Regions: The whole country/..[indicate regions covered] 2. Purpose of the survey The purpose of this survey is to collect mid year national average prices as paid by contractors for resource inputs to construction work. The prices will contribute to the preparation of Purchasing Power Parities (PPPs) for construction as part of a worldwide exercise coordinated by the World Bank and called the International Comparison Program. PPPs are currency convertors (as an alternative to market exchange rates) that permit comparisons of construction volumes across countries to be made. 3

4 3. Sources of prices It would be helpful if the main sources of prices could be indicated for example, personal experience, manufacturers or agents price lists, sales invoices, published price books, etc. If all or most prices come from a single source, please indicate that against each resource heading; if there is a range of different sources, please insert items and sources as appropriate below each resource heading. Items Materials and products generally Sources Equipment hire generally Labour generally 4. Base date for prices Ideally, prices should be an average for the year A mid year price may be acceptable but please note if prices are seasonal. If the prices have a different base date, or if there is seasonality, please indicate that here and the likely adjustment factor to bring prices to a mid 2011 base. Base date (if different from above) Adjustment factor 5. General notes 1. The intention is to identify, and collect prices for, locally available, commonly used materials and products that are equivalent, if not identical, to the items described in the survey documents. The following notes are intended to assist in selecting and pricing the survey items. Item descriptions and s 2. Specified materials and products: Item descriptions in the survey are intended to provide a clear description of the item to be priced. There is, however, a tension between the tightness of the specification and the content of the item to be priced the tighter the specification, the more 4

5 country-specific it becomes. If a precise match to the specified material or product is not commonly available or used, the nearest commonly available and used equivalent should be priced and an appropriate note inserted in Column Proprietary products: Generally, item descriptions in the survey do not use proprietary names but respondents can provide proprietary names in Column 8 if that simplifies the note. 4. Detailed dimensions of materials: Generally, metric dimensions are stated in the survey documents but these can be replaced by Imperial or other dimensions if these are more common in the country. Detailed dimensions of material and products will vary, both between and within countries, for example the dimensions of bricks and blocks or timber sections. Survey respondents should select the nearest locally available and commonly used equivalent to the item described in the survey and where that varies from the survey description it should be noted in Column Units of measurement: Again, metric s are generally used in the survey documents but other s can be inserted. Alternative s of measurement can also be provided, for example, m2 for plywood is preferred but a price per sheet indicating the dimensions of the sheet (length and width) is acceptable; similarly, cement is indicated as per Tonne but per kg or per 50kg bag is acceptable. The items and s should be as normally used in the country. Preferred s are indicated in Column 4; alternative s should be inserted in Column 5 and, if any notes are required, these should be inserted in Column The s indicated for equipment hire are per hour but if other s are normally used, for example, per day or per week, these should be indicated in column 5. If the s are per day or per week, please indicate in Column 8, the typical numbers of hours worked per day or per week. It is assumed that equipment will be hired with an operator; if this is not the case, please indicate this in Column The s indicated for labour are per day but if other s are normally used, for example, per week, per month or per year, these should be indicated in column 5. If the s are per week or more, please indicate in Column 8, the typical numbers of hours worked per week, month or year. Prices 8. Prices provided should be those paid by construction contractors to their suppliers. In the case of materials and products, that will typically be the prices paid to manufacturers or intermediaries (agents or merchants), including all non-recoverable taxes; in the case of equipment, the rental charges paid to hire companies or internal hire rates; and, in the case of labour, the cost to the contractor of employing the workers. Informal payment arrangements for labour are common in construction - for example some payment is in the form of wages, subject to taxes and on which employers costs are incurred while other payments are in cash - and respondents should bear this in mind when determining what is an average wage. After each section in the survey, there is space for notes on pricing; it is important that these are completed by respondents. 9. Prices should be provide for items that are commonly available and commonly used in the country; they should not be provided for items that match the item description precisely if that involves pricing a special item, either not generally available or only available at a premium price. 5

6 10. The survey seeks annual and national average prices in national currency. Annual averages mean prices that are an average over the survey year (mid-year prices are acceptable) and that average different price levels across the country, across different site contexts and across different types and sizes of projects. The following notes are intended to help respondents select appropriate average prices for their country. Space is provided for notes on the basis of average prices. 11. Regional location: Construction prices can vary across countries, as a result of local resource and distribution costs, geographic, seismic or climatic conditions, local market conditions, etc, particularly in large countries and sometimes these variations can be significant. Respondents should consider the extent of regional variations when pricing items and make a judgement on what is a realistic national average. Space is provided for notes on regional location. 12. Site context: Construction prices can vary depending on detailed site conditions, for example, across constrained city centre sites, greenfield sites adjacent to urban areas and remote sites that are difficult to access. When pricing items, respondents should assume reasonable site contexts with good access. 13. Size of projects: The size of projects can influence the cost of resources, particularly materials and equipment large quantities and long periods of hire can reduce costs. Prices should be provided for medium-sized projects, that is, projects which are not unusually small or unusually large. Space is provided for note on the likely extent of price discounts. 6

They have usually received little or no formal training. Examples of tasks that they might undertake include loading and unloading materials, digging and filling holes and trenches, spreading gravel and related materials, cleaning and tidying sites and site facilities. [2] this group of skilled construction workers has received training in their trade comprising one or more of an apprenticeship, on the job training or training in a technical college or similar institution.
