What construction price databases are
A construction price database is a catalog of unit reference prices, labor, materials and machinery, that serves to budget without having to negotiate each line item from scratch. In Spain there are several official databases, some of regional scope (like those published by construction institutes of various autonomous communities) and others of national scope, generated by technical entities in the sector.
No price database replaces an actual supplier and subcontractor quote: it serves as a starting reference for estimating and comparing, not as a fixed price that can be treated as good without checking against the local market at the time of contracting.
How frequently price databases are updated
Update frequency varies by database: some autonomous communities publish an annual edition of their price database, while others review it more frequently. National scope price generators typically update material prices more frequently, more volatile, than labor prices, linked to collective agreements that change less often.
Using a price database without checking the date of its last update is a common mistake: a reference price from two or three years ago can differ significantly from the actual current cost, especially in materials sensitive to market variations.
How to choose which price database to use
The choice depends on the autonomous community where the work is executed, if an official regional database exists, it is usually the reference most adjusted to that local market, and on the type of work: some databases are more oriented toward residential construction, others better cover civil or industrial works. For public tenders, it is advisable to check whether the specifications require the use of a specific price database before budgeting with a different one.
Combining more than one price database as a contrast, instead of relying on a single source, helps detect if a specific price is outdated or simply reflects a real market difference between territories.
Limitations of generic price databases
A generic price database does not account for specific conditions of each work: complicated access, working height, tight schedules or particular site conditions can increase a line item above the reference price without that meaning a budgeting error. The reference price is a reasonable starting point, not the final price that corresponds to any work with those characteristics.
Adjusting the reference price with real knowledge of the specific work, not just copying the catalog price, is what separates a reliable budget from a generic one.
How Bloqbase supports the use of reference prices
Bloqbase can help keep recorded the unit prices the builder usually uses, comparing them with external reference ones when it is advisable to check if an internal price has become outdated.
The software does not generate or maintain an official price database: that reference must be obtained from the corresponding regional or national sources and checked against the actual conditions of each work.
