About us
Survey expertise from people who work on site
SJS Site Engineering provides experienced site engineers and surveyors to construction clients. The same people who set out and survey on live sites every day deliver our measured survey services.
We understand what designers, contractors and project managers need from survey data: accurate, clearly presented, delivered in the right format and on time. Every job is coordinated, checked and drawn by our own team.
Site-ready teams
Engineers used to working on live construction, highway and rail sites.
Right first time
Coordinated to OS National Grid, with independent checks on every survey.
Your format
CAD, PDF, point cloud or BIM, drawn to your standards.
