摘要

A quotation calculation device (100) comprises: a specifications acquisition unit (110) that acquires specifications information indicating the specifications for facilities attached to a building which are to be constructed; a construction example acquisition unit (120) that acquires construction example information including past specifications information indicating the specifications of past facilities attached to a building constructed in the past, and past cost information indicating the cost required when the past facilities attached to a building were constructed, the construction example acquisition unit (120) also acquiring construction example information in which the specifications indicated by the past specifications information are similar to the specifications indicated by the specifications information; a quotation calculation unit (130) that calculates, on the basis of the past cost information, a quotation of cost required to construct the facilities attached to a building which are to be constructed; a cost-reducing specifications item extraction unit (150) that extracts a specifications item which might reduce the quoted cost if the specifications indicated by the specification information are changed, on the basis of the past specifications information and the past cost information; and an output unit (190) that outputs quoted cost information indicating the quoted cost, and cost-reducing specifications item information indicating the specifications item extracted by the cost-reducing specifications item extraction unit (150).
