A floor plan is more than rooms and walls. Circulation, function, accessibility, and code requirements all influence how the layout comes together before the drawing set is complete. Talk to an Architect → dotecengineering.com
Planning an HVAC or building-systems project? Bring MEP design in early so loads, equipment, routing, and clearances can be coordinated in the drawings. Talk to an Engineer → dotecengineering.com
HVAC load calculations define the heating and cooling demand before equipment is selected.

Good HVAC design starts with the load, not the duct. Heating and cooling requirements help guide equipment sizing and the system layout before routing is coordinated in the drawings. Talk to an Engineer → dotecengineering.com
Electrical load calculations help size the power system around the building’s actual demand.

This month we covered civil site design, HVAC sizing, structural design, 2D/3D modeling, solar, and architectural design.
Which one do you want more of?
Great working with @Pristinebuilder on this project. DOTec supported the civil engineering design side, and we appreciate the trust in our team.
Thank you for the collaboration. We look forward to working together again.
Every project starts as an idea. DOTec turns early concepts into coordinated engineering drawings that move your project forward.

Doing a tenant improvement? Layout, egress, accessibility, code review, and permits all have to happen.
Which one usually gets left to the last minute?
Adding a mezzanine or rooftop equipment changes the structural load. The existing structure should be checked before the new load is added.

Retrofitting a plant? Accurate existing-condition data can be turned into as-built drawings and models so the new design fits what is actually there.
