Creator and maintainer
PlanCalq was created and is maintained by Carl Rogie Ortega. Carl is responsible for the product direction, calculator implementation, explanatory content and ongoing corrections published on PlanCalq.
PlanCalq does not present Carl as an architect, engineer, licensed contractor, electrician, plumber, quantity surveyor or other qualified construction professional. Calculator methods and guides are planning resources, not professional technical review. If a page is ever reviewed by a qualified professional, that review will be identified explicitly rather than implied.
Why PlanCalq exists
Home projects rarely stop at one calculation. Knowing that a room is 24 square metres is useful, but the next questions are usually how much material to buy, how much waste to allow, how the product is packaged and what the purchase might cost.
PlanCalq is designed around that planning journey. The calculators remain the core product: practical tools for paint, tile, flooring, concrete, landscaping, energy and other common project quantities. Supporting guides explain the assumptions and decisions around those tools rather than turning the site into a generic home-improvement blog.
Connected project measurements
My Project lets you save a room or project area in your browser and reuse its dimensions across compatible tools. Saved estimates can be viewed together as a project snapshot. In the current product, those measurements stay on your device unless a future feature clearly tells you otherwise.
How we approach accuracy
Calculator pages publish their calculation method, assumptions, worked examples and limitations so the result can be checked rather than treated as a black box. Product-specific inputs such as coverage, yield and pack size should be replaced with the values from the actual product whenever available.
PlanCalq avoids presenting a universal market price where local supplier pricing is more appropriate. Most cost tools therefore use prices entered by the user. The same principle applies to building requirements: universal geometry is kept separate from local codes, permits and professional design decisions.
Planning, not professional certification
PlanCalq focuses on quantities, measurements, material planning, energy estimates and costs. It does not replace an architect, engineer, licensed contractor, electrician, plumber, quantity surveyor or building official where the project requires professional design, safety assessment, permits or code compliance.

Corrections and contact
Useful tools improve when errors are easy to report. If you find a calculation problem or unclear assumption, send the tool name, the inputs you used and the result you expected to plancalq@gmail.com. General feedback and guide suggestions are welcome too.
