Frequently Asked Before Inquiring
Answers to common questions regarding our technical review process and reader communications.
Can I submit plans or tender quotes for review?
Yes. We welcome anonymized architectural blueprints and contractor tender schedules for empirical research. Our quantity surveying team uses real-world tenders to calibrate our 90-day cost benchmarks.
Do you recommend local builders in my municipality?
No. To preserve our strict commercial independence, we never recommend specific builders or accept referral commissions. Instead, we provide exhaustive contractor vetting frameworks you can execute yourself.
How do I submit an update to a building code reference?
Email our corrections desk with the article link, the relevant national standard citation (e.g. NCC or IRC clause), and your supporting documentation. Verified updates are logged in our public register.
Do you accept sponsored posts or paid links?
Under no circumstances. We enforce an absolute ban on sponsored articles, paid guest posts, and commercial backlink placements to safeguard the integrity of our engineering manuals.
