Calculul indicilor <strong>de</strong> cost în construcţii se faceutilizând elementele <strong>de</strong> cheltuieli şi pon<strong>de</strong>rile aferenteanului 2005. Sistemul <strong>de</strong> pon<strong>de</strong>ri utilizat în calcululindicelui <strong>de</strong> cost în construcţii se stabileşte separatpe fiecare categorie <strong>de</strong> lucrări, respectiv obiect. Caelement <strong>de</strong> pon<strong>de</strong>rare se foloseşte greutateaspecifică (structura) a fiecărui element <strong>de</strong> cheltuialăfaţă <strong>de</strong> total.Principalele elemente <strong>de</strong> cheltuieli sunt:- materialele (reprezintă valorile materialelor <strong>de</strong>construcţii);- manopera (reprezintă câştigurile salariale brutelunare în ramura construcţii);- echipamentele (reprezintă cheltuielile pentruutilajele proprii, precum şi cheltuielile cuutilajele închiriate);- transportul (reprezintă cheltuielile pentrutransportul materialului <strong>de</strong> la producător până lalocul execuţiei categoriei <strong>de</strong> obiecte <strong>de</strong>construcţii);- cheltuielile indirecte (reprezintă salariilepersonalului indirect productiv, cheltuielile <strong>de</strong>aprovizionare, <strong>de</strong>pozitare, cheltuielile cu regiaîntreprin<strong>de</strong>rii: chirii, energie, birotică,comunicaţii).Pe elemente <strong>de</strong> cheltuieli, indicii <strong>de</strong> preţ <strong>de</strong> tipLaspeyres folosiţi sunt:- Indicele preţurilor producţiei industriale pentrumateriale <strong>de</strong> construcţii (IPPI);- Indicele costului forţei <strong>de</strong> muncă în construcţii;- IPPI pentru utilaje <strong>de</strong> construcţii;- IPPI pentru mijloace <strong>de</strong> transport;- Indicele preţurilor <strong>de</strong> consum.Indicii <strong>de</strong> cost în construcţii sunt calculaţi ca mediepon<strong>de</strong>rată a indicilor <strong>de</strong> preţ ai materialelor <strong>de</strong>construcţii, ai utilajelor din construcţii, ai cheltuielilor<strong>de</strong> transport şi ai cheltuielilor indirecte precum şi aindicelui câştigului salarial nominal brut. Pon<strong>de</strong>rileutilizate pentru agregare reprezintă structuracheltuielilor în construcţii rezultată pe bazaanchetelor statistice specifice realizate cuperiodicitate <strong>de</strong> 5 ani (ultima realizată pentru anul <strong>de</strong>bază 2005).Indicii <strong>de</strong> cost în construcţii sunt calculaţi pe totalramură construcţii (secţiunea F CAEN Rev.2), peelemente <strong>de</strong> structură (lucrări <strong>de</strong> construcţii noi,reparaţii capitale şi lucrări <strong>de</strong> intreţinere şi reparaţiicurente) şi pe tipuri <strong>de</strong> construcţii (clădiri rezi<strong>de</strong>nţiale,clădiri nerezi<strong>de</strong>nţiale şi construcţii inginereşti).Indicii <strong>de</strong> cost în construcţii sunt provizorii şi serevizuiesc pe baza rectificărilor ce se efectueazăretroactiv <strong>de</strong> către întreprin<strong>de</strong>rile din eşantion, asupradatelor furnizate anterior <strong>de</strong> către acestea.The construction cost in<strong>de</strong>x is calculated using thecost components and weights corresponding to theyear 2005. The weighting system used in thecalculation of the construction cost in<strong>de</strong>x isestablished separately for each category of worksand objects, respectively. The specific weight(structure) of each cost component as against thetotal is used as a weighting element.The main cost components are:- material cost (represents the value ofconstruction materials);- labour cost (represents the monthly grosswages for constructions);- equipment cost (represents the expenditure forown equipment as well as for lease<strong>de</strong>quipment);- transport cost (represents the expenditurefor the transport of the material from theproducer to the construction site);- indirect costs (represent the wages of indirectlyproductive employees, supply expenditure,storing expenditure, enterprises maintenanceexpenditure: rents, energy, office consumables,communications).The price indices of Laspeyres-type used foreach cost component are:- Industrial production price in<strong>de</strong>x forconstruction materials (IPPI);- Labour force cost in<strong>de</strong>x in constructions;- IPPI for construction equipment;- IPPI for transport means;- Consumer price in<strong>de</strong>x.Cost indices in construction are calculated asweighted mean of construction materials priceindices, construction equipment indices, transportexpenditure and indirect expenditure as well as thegross nominal earnings in<strong>de</strong>x. The weights used foraggregation represent the expenditure structure inconstruction based on specific statistical surveyswith 5 year periodicity (the last one was for the baseyear 2005).Cost indices in construction are calculated per totalconstruction branch (CANE Rev.2 F section), bystructure elements (new construction works, capitalrepairs and maintenance works and current repairs)and by construction type (resi<strong>de</strong>ntial buildings,non-resi<strong>de</strong>ntial buildings and engineeringconstruction).Construction cost indices are provisional and arerevised based on rectification retroactively done bysample enterprises, on data previously provi<strong>de</strong>d.16
