I've successfully delivered similar comprehensive MEP design packages for large-scale commercial developments, including detailed BIM coordination and construction documentation, ensuring seamless integration of HVAC, electrical, and plumbing systems. My approach prioritizes clash detection and constructability from the outset, mirroring the critical coordination you require. My technical approach involves leveraging Revit for all design disciplines (MEP, Fire Protection) and Navisworks for federated model creation and clash detection. I'll begin with schematic design, developing system layouts and equipment selections, progressing to detailed design with precise ductwork, piping, and conduit routing. Final construction documents will include detailed drawings, schedules, and specifications, all coordinated within the BIM environment. To ensure alignment, could you clarify the preferred level of detail for the BIM model (e.g., LOD 300, 350) and any specific energy modeling requirements for the HVAC systems? I'm eager to discuss how my expertise can benefit your project and would welcome a brief call to explore this further.

Hi, Bojan here, from Serbia. What matters most in completing your commercial building MEP with AHU and FAHU systems and smoke extraction is drawings and calculations that pass review and can be built as designed. I'm a senior CAD and design engineer with 8+ years of experience working with AutoCAD, Solidworks, CAD/CAM and Mechanical Engineering. With Revit, the real challenge is matching codes and site conditions. A common issue: finishing detailed drawings before the key design inputs are confirmed, so everything gets redrawn. My plan: first, confirm the design inputs, codes and site data. Then, prepare the calculations and drawings in Revit. Finally, check them against the codes and deliver editable files. I've done engineering design work in AutoCAD. A few questions to better understand the scope: 1. Which code or standard must the design follow? I set it at the start, so calculations pass review the first time. 2. Use one title block and template for all sheets? I'd recommend it, every sheet reads the same for reviewers. 3. Will the package support financing or permits? Then I format the report the way lenders and permit offices expect. I can start right away. Happy to go over the details here in chat and suggest the best approach. Looking forward to hearing from you, Bojan

With an extensive 20-year background in both theoretical and field experience, my practical knowledge in structural analysis meshes with my advanced skills in Revit Structure and AutoCAD. Additionally, my expertise in Bill of Quantities and Cost Estimation could be quite valuable for a comprehensive commercial MEP project, such as yours. Not only can I provide accurate calculations and construction documentation but also high-quality BOQs. In tandem with my engineering proficiencies, I possess a Diploma in AutoCAD & Interior Design which aligns well with your requirement for CAD coordination and detailing. Moreover, the fact that I'm just finishing my B-Tech in Civil Engineering indicates my familiarity and up-to-datedness with the subjects you require for this project. Although I'm new to commercial buildings design specifically, my experience extends to residential and institutional developments. This has given me the adaptability to learn quickly and deliver effectively for diverse projects. So, should you choose me, you'll not just be tapping into an experienced 20-year veteran but also someone eager to bring freshness and intelligence to this project which your smart city!
