problems of construction treatment
Problems of construction treatment
  • Complexity of construction
  • Country specific nature
  • Great variability of construction across country
  • There are no identical construction projects in the one country
problems of construction treatment continued
Problems of construction treatment (continued)
  • Employment of external experts
  • Expensive to use standard price approach due to number of participating countries and types constructions
approaches applied for construction treatment
Approaches applied for construction treatment
  • Identical construction in all countries
    • Lead to comparable but not representative
approaches applied for construction treatment continued
Approaches applied for construction treatment (continued)
  • Typical construction in all countries
    • Lead to representative but not comparable
approaches applied for construction treatment continued6
Approaches applied for construction treatment (continued)
  • Standard (fictitious) construction in all countries
    • Compromise between representativity and comparability of construction
oecd eurostat approach
OECD- Eurostat approach
  • Use the third approach
    • Price several standard construction projects
standard construction projects
Standard construction projects
  • Consist of number major works: earthworks, concrete, masonry, roofing etc.
  • Each major component comprises a number of elementary components
    • Excavation of foundations, transportation of spoil, etc.
standard construction projects continued
Standard construction projects (continued)
  • The major components and their elementary components of the standard projects are detailed in bills of quantities
  • Each country should price the same bills of quantities with allowed some flexibility
major problems of standard construction projects
Major problems of standard construction projects
  • Low representativity of construction projects
  • High price of data preparation
  • Only few projects are priced
  • Often research work
  • Practically no checking across major and elementary components
cis approach
CIS approach
  • Use during 2000 comparison
similarities between cis and eurostat oecd approach
Similarities between CIS and Eurostat- OECD approach
  • Use standard fictitious construction projects
  • Use GDP classification
main features of cis approach resources technological models rtm
Main features of CIS approach(resources-technological models(RTM))
  • Construction projects and works divided into main elements
    • Materials, wages, some financial indicators (estimation, incl. VAT)
  • Each construction projects are defined by unique set of consumed materials, labour and etc.
main features of rtm continued
Main features of RTM (continued)
  • Materials are defined as representative items
  • Countries collect prices for materials and report wages and necessary indicators
  • Construction projects are calculated centrally by employed experts after standard price checking
changes between 2000 and 2004 2005
Changes between 2000 and 2004/2005
  • Trimmed list of materials and indicators
  • Possibility to take into account labour productivity
output to use rtm
Output to use RTM
  • Could use more number construction projects for representativity identification
  • Use standard software of ICP for price checking
  • More statistical exercise
  • Data transparency
  • Reduce labour and financial input for countries
basket of construction components cis experts analysis
Basket of construction components CIS experts analysis
  • Who is expert in CIS region?
  • CO-INVEST company, leading Russian company in supply of construction cost information in CIS region and in building and organisation price indices
  • CO-INVEST works with tight collaboration with RSMeans, North America's leading supplier of construction cost information
finding problems with bocc implementation
Finding problems with BOCC implementation
  • Absence of unified list of components with clear description of specifications
  • GDP classification requires comparison of construction projects not components
  • Lack of weighted data of components by sectors, f. e. in CIS countries
  • No using existing statistical system
finding problems with bocc implementation continued
Finding problems with BOCC implementation (continued)
  • Questionable availability of detailed information
  • Requires employment of highly qualified external experts for calculating procedure
  • High cost
some solutions
Some solutions
  • Close collaboration between experts
  • Finding more appropriate way using RTM technology
  • Additional financing
