纵横工程造价软件 is provided by 珠海纵横创新软件有限公司, founded in 2003, with a focus on engineering software, engineering training, and engineering cost services. Its official product lineup covers the 大司空 cost-estimation digital platform, cloud pricing, cloud quantity measurement, measurement/payment/settlement/final accounts, highway cost estimation, maintenance cost estimation, fixed bill of quantities, and highway quantity takeoff, with a strong focus on transportation, highway, and related engineering cost scenarios.
Its desktop cost-estimation software emphasizes preparing estimates, preliminary estimates, budgets, and bill-of-quantities budgets based on highway engineering quotas and local supplementary regulations. It supports template cloning, location-based search, enterprise quotas, BOQ price adjustment, parametric design, material price-difference adjustment, real-time calculation, cost review, and drawing-based quantity verification. Its quantity takeoff product can read Excel engineering quantity sheets and automatically calculate quota-based quantities and BOQ quantities. The fixed BOQ product is designed to reduce data errors caused by repeated Excel interactions and ensure consistency between the base tender price and the published BOQ. Cloud quantity measurement emphasizes dynamic full-process management from “preliminary estimate to measurement to final accounts.”
The official website explicitly lists “纵横大司空公路网络版 Free” and “Click here to use for free,” and also provides downloads for some learning editions. However, for the Professional Edition, Project Professional Edition, Tendering Edition, Multi-user Professional Edition, and others, it only shows downloads, version numbers, lock numbers, and encryption-lock upgrade notices, without disclosing specific prices, purchase methods, or subscription terms.
The advantages are its clear industry depth, covering high-frequency scenarios such as new highway construction, reconstruction and expansion, maintenance, bidding, BOQ fixing, and quantity takeoff; detailed updates to quotas, reports, and local versions; Excel/PDF import and export that fit traditional cost-estimation workflows; and a service network across 32 provinces, municipalities, and autonomous regions in China, plus a 24/7 hotline that strengthens delivery capabilities. The drawbacks are insufficient disclosure of enterprise SaaS information, such as permission models, data security, APIs, third-party integrations, and cloud deployment details; the desktop software still depends on Windows and encryption locks, and 纵横Z+ also states that it is not compatible with Windows XP and some Windows 7 systems.
It is suitable for users in highway engineering design, construction, project ownership, cost management, consulting, audit and review, supervision, and academic training, especially teams that need to comply with transportation industry quotas, local pricing rules, and fixed BOQ workflows.
