Title: Price of Building Work


1
Price of Building Work
2
Item of Budget of Building Part
  • Numeral code of item (Classification of Building
    Constructions and Works)
  • Description of item
  • Measure unit
  • Amount of item in measure unit
  • Unit price in e.g. CZK per measure unit
  • Totally per item
  • Unit weight in tons
  • Weight in tons totally per one item

3
Standard classification of production
  • Standard classification of production is
    connected and compatible with the classification
    of
  • production of the EU. Subjects of classifications
    are
  • physical products (goods)
  • all industrial, agricultural, wood and other
    product sold by producer for the next use
  • works of production character (working
    activities)
  • works focused on the production of new tangible
    property or its part
  • services (activities)
  • activities not focused on the creation of new
    tangible assets, as services, repairs,
    maintenance
  • Main classifying element is a section signed by
    code of two numbers, then follow next
  • numbers specifying the subject of classification
    more directly group class, category,
  • subcategory.
  • For the building industry there is intended
    section 45 - Building works (works on new
  • structures, reconstructions, modernizations,
    repairs and maintenance)

4
Standard classification of production
  • Section 45 Building industry is classified in
    the following way
  • 45.1 Preparative works for realization
  • 45.2 Fabric - building and engineering
    constructions
  • 45.3 Building installations
  • 45.4 Internal building works, finishing works
  • 45.5 Lease of machines and equipment with stuff
  • 45.21 Construction works on fabric of buildings
    and engineering structure
  • 45.22 Roof construction, laying of roofage
  • 45.23 Construction on fabric of communications
    and airports
  • 45.24 Works on fabric of water constructions
  • 45.25 Specialized building works
  • 45.41 Parging works
  • 45.42 Building locksmithing and joinery
  • 45.43 Facing of walls, covering of floors
  • 45.44 Decorating, lacquering and glazier works
  • 45.45 Other internal works

5
Classification of Building Constructions and
works
  • Classification of Building Constructions and
    works (Trídník stavebních konstrukcí a prací
    TSKP) sorts partial results of building
    production building works and creates the base
    e.g. for the structure of budget that serves for
    the building construction price establishment
  • as a base of the sorting of building construction
    it was chosen the building section as a function
    part of a building object
  • Scheme of a code
  • 1. 2. 3. 4. 5.
  • Group of building sections
  • Building section
  • Kind of construction or work
  • Detailed characteristics

6
Overview of Groups of Building Sections
Number Title of group of building sections
0 General construction and works
1 Earthworks
2 Foundations, special foundations
3 Vertical and complete constructions
4 Horizontal constructions
5 Communications
6 Construction of surfaces, floors
7 Associated building production (handcrafts, installations)
8 Pipage, conduction
9 Finishing works, demolitions
Item budget
7
Data for the Budget Preparation
  • Documentation of building (drawings, design,
    technical report)
  • Technologic processes
  • Price catalogue of building works
  • Price catalogues of material for valuation of
    materials in specifications
  • Prices agreed with sub-suppliers

8
Costing Model (Formula)
  • Unit price of building work
  • Direct costs (DC)
  • Direct material (M)
  • Direct wages (W)
  • Other direct costs (ODC)
  • Machines and machinery (S)
  • Indirect costs (IC)
  • Overhead product costs (OPC)
  • Overhead administrative costs (OAC)
  • Profit (P)
  • Price totally

9
Costing Model Direct Costs
  • Direct material (M - determinable)
  • Number of item
  • Description of item
  • Measure unit of item
  • Norm of consumption
  • Purchase price of material
  • Item totally
  • Unit weight
  • Weight totally per item

10
Costing Model Direct Costs
  • Direct wages (W - determinable)
  • Code (number) of profession
  • Description of profession
  • Output in standard (man) hours (Nh)
  • Wage hour tariff (CZK/hour)
  • Item totally

11
Costing Model Direct Costs
  • Machines and machinery (S with determinable
  • Output)
  • Code (number) of machine (own company's
    classification)
  • Description of machine
  • Output in standard (machine) hours (Sh)
  • Tariff per Sh
  • Item totally

12
Costing Model Direct Costs
  • Other direct costs (ODC)
  • Payments to funds of social and health insurance
    from direct wages
  • Transport costs (realized by own car or bought
    transport services)

13
Costing Model Indirect Costs
  • Overhead product costs (OPC)
  • Includes all kinds of costs arising in the frame
    of production as a group of costs connected with
    realization of more activities (building works)
  • For example
  • Costs for bought services connected directly with
    production process (telephones, energy instead
    direct costs for machines)
  • Costs for consumption of overhead materials
  • Wages of foremen, site engineers etc. including
    payments into funds of social and health insurance

14
Costing Model Indirect Costs
  • Overhead administrative costs (OAC)
  • includes all costs connected with administration
    and management of company
  • For example
  • costs for bought services connected with
    administration of company (telephones, energy,
    leases)
  • costs for overhead material consumption
  • wages of workmen including payments into funds of
    social and health insurance
  • depreciation of long-term property

15
Costing Model Profit
  • Profit
  • assigned according to the
  • requirements of company
  • possibilities coming from situation on the market
  • Price totally DC (MWODCS) IC (OPCOAC) P

16
Price of Building Work calculation for
production unit (m.u.)
  • Costs for material per item in CZK
  • Norm of material consumption x purchase price of
    material
  • Cost for wages per item in CZK
  • Amount of Nh x wage hour tariff
  • Possible premium payments in from wage
  • Costs for machines per item in CZK
  • Amount of Sh x hour tariff of machine work
  • Other direct costs totally in CZK, payments into
    funds
  • ? Costs for direct wages x 0,35 (year 2006)
  • Overhead production costs in CZK tariff x basis
  • Overhead administrative costs in CZK tariff x
    basis
  • Profit in CZK tariff x basis

Calculation of Tariff per Sh
  • Costing model
  • Costs for purchasing and running (without
    fuelling or energy)
  • Annual depreciation
  • Annual costs for repairs and maintenance
  • Annual costs for moving with machinery
  • Costs per an hour of machine running (without
    fuelling and energy)
  • Annual costs for machine totally / Annual number
    of hours of machine running
  • Costs for fuelling or energy per an hour of
    machine running
  • Norm of consumption x Purchase price
  • Calculation tariff of machine (for building works
    price establishment)
  • Costs for purchasing and running Costs for
    fuelling and energy
