More than a set
of numbers.
Founded in 2021, SJ Estimating House brings together an estimating team with more than nine years of industry experience. Our work supports the decisions that sit between a drawing, a supplier enquiry and a construction tender.
For New Zealand projects, that means understanding the agreed scope, reading the drawings alongside the specifications, and keeping assumptions visible. We work remotely with your team and tailor the handover to the way you price and review a project.
We do not replace the people making design, engineering or compliance decisions. We help them work from a clearer measurement and estimating basis.
