Caswydawnictwo

The Polish construction cost-index family used for contract indexation, sold as a subscription platform rather than as books. Components: KCOB (price catalogue for building objects), KCOE (energy objects), KCOD (roads), KCOK/KCOT (railway), KCOSZ/KCOZT (external networks and site development), plus the index/calculator layer — KWZC (Catalogue of Price Change Indices, valuation and projection), KWKZ, KWZ, KWO (reproduction value) and KKRI (investment realisation cost). The distinctive property is cadence and horizon: 'waloryzacja live' is updated weekly for the KCOB/KCOE/KCOD index families, and the current KWZC release (Q3 2026) carries published price projections forward to 2029. Delivered through a Centrum Kalkulacji of online calculators for every catalogue, so the indices are computable per object type rather than printed as bare percentage tables.

Type: not stated
Format: Tabular index series plus online calculators — quarterly and weekly index tables by object type and cost element, exposed through per-catalogue calculation tools on the CAS Platform, with an educational tier distributing watermarked files. Historically published in book form alongside the platform, so both a print edition and a digital series exist for the same vintage.
Volume: Not published as record counts; the series dimensions are the volume. Composition: five-plus object price catalogues (building, energy, road, railway, external networks/site development) each with its own index family, plus KWZC quarterly index-and-projection releases (current vintage Q3 2026, projected to 2029), weekly valuation updates for the KCOB/KCOE/KCOD families, and a calculator repository covering every catalogue (KCOB, KCOE, KCOD, KCOK, KCOSZ, KCOZT, KWZC, KWKZ, KWZ, KWO, KKRI). Bundled CASPACK packages exist for specific professions (budget units, property assessors), implying enough content to support segmented subscriptions.
Users: Not disclosed; a self-serve e-commerce account model (login/registration on the store, platform accounts created by email) with three seat tiers — Specjalista, Mały zespół, Duży zespół. Est. low thousands of accounts (inferred from the volume of book and platform SKUs, a network of partner bookshops in four cities, and a published list of named user segments including budget units and property assessors).
History: not stated
Update frequency: not stated
Growth: Active — current KWZC vintage is Q3 2026 with a live weekly valuation feed marketed as exclusive to the platform, product imagery refreshed in March 2026, a multi-tier seat ladder and promotional discount thresholds indicating an active commercial motion, plus an expert-meeting booking flow and reported research reports alongside the data subscriptions.
Launched: The publishing house predates the platform: the operating entity's KRS number (0000659441) and REGON (366393384) sit in the sequences assigned around 2016-2017, and CAS's construction cost catalogues have a long print history in Poland. The digital CAS Platforma subscription product is the newer layer, with site branding assets from 2024 and product imagery from 2026 indicating a recent re-platform. No explicit launch date is published.
