Abstract: A computer-implemented method comprises storing a plurality of construction project specification documents in a data storage system. The method further comprises, for each of the plurality of construction project specification documents, extracting a plurality of blocks of text from the document, extracting formatting information for the document based on the extracted text blocks, generating a location descriptor for each of the text blocks based on the formatting information, the location descriptor indicating the location of the text block within the document, determining the type of text contained in each of the text blocks, and storing the location descriptor and the type of text contained in the text block for each of the text blocks.

Abstract: A system comprises a data storage system, data analysis logic, and user interface logic. The data analysis logic is configured to analyze the documents and to identify documents that satisfy search criteria received from a user. The user interface logic is configured to generate a user interface. The user interface logic is also configured to generate a plurality of charts for display to the user. The user can interact with the charts to specify modified search criteria. The user interface logic is configured to receive modified search criteria from the user via one of the charts and update the remaining charts to reflect the modified search criteria.
