GDL Consultancy is a software studio focused on the construction industry. It emphasizes that its team comes from backgrounds in surveying, specialist contracting, and construction-related roles, rather than being a generic SaaS team pivoting into the construction market. Its first product, MarkMetric, is a browser-based PDF takeoff tool for construction estimators. It is used to measure quantities from construction drawings, calculate amounts, generate a Bill of Materials (BoM), and export PDFs with annotations and calculation details.
MarkMetric’s strengths are centered on the real-world complexity of construction quantity takeoff. First, it supports multi-drawing workflows, allowing quantities to be summarized and checked across a full drawing set instead of treating each sheet in isolation. Second, it supports multiple scales within a single drawing; examples in the source text include a site plan at 1:500 and detail drawings at 1:20, reducing the need to split files. Third, it offers supplier-aware price lists, allowing prices to be managed by supplier, project, and client, so the BoM can be priced more accurately and automatically.
The collected text does not disclose plans, subscription fees, a free version, or trial policy, nor does it specify payment methods. On deployment, the only confirmed detail is that it is a browser-based tool, meaning users access it through a web browser. It is not clear whether it is fully cloud-based, whether self-hosting is supported, or where data is stored.
Its main advantage is a clearly defined product focus: PDF takeoff, BoM generation, and quote defense for construction estimators. The team’s industry experience also adds credibility. Compared with general-purpose PDF markup tools, its support for multi-drawing workflows, multiple scales, and supplier price lists is closer to actual construction estimating processes. The downside is that public information is limited. There is little detail on third-party integrations, team permissions, audit trails, security and compliance, APIs, or support services, so procurement evaluation would require further discussion with the vendor.
MarkMetric is best suited to construction estimators, surveyors, technical teams, and specialist contractors—especially teams that frequently calculate quantities from PDF drawings and need to explain the basis for quantities and BoMs to clients or procurement teams. If an organization needs a mature project management suite, ERP integration, or large-scale permission governance, the available information is not sufficient to judge fit.
The text does not provide information on network accessibility from China, a Chinese-language interface, local payment methods, or local services, so china_access should be considered unknown. Chinese users should first test site and login availability, and compare it with alternatives such as 广联达, Autodesk Construction Cloud, Bluebeam, PlanSwift, and CostX.
