You get the schedule in writing before the first day on site
A price tells you what it costs. A schedule tells you who is on site, in what order, and when each stage finishes. We give you both, then run the job against them.

A civil engineer who has managed construction since 2011
Construction has been Founder Johnpaul Guminkiriza's passion since childhood, when he loved watching worthless-looking spaces become something magnificent. He is a member of the Project Management Institute (PMI). He started as a site engineer in his first year of university, rose to project manager and then director, and went on to found Jopie Construction Group, running building projects for government, consultants and private clients along the way. He holds a BSc in Civil Engineering and an MBA in construction management.
That is the discipline behind every Jopie job: a written scope, a realistic schedule, an honest budget, and one point of contact who keeps it on track, whether the job is a bathroom or a commercial fit-out.
