I will soon issue a full drawing package—over 1000 m²—for a new development in the Republic of Congo. If you are a full-case designer or Agency who can undertake the construction drawings of building structures, HVAC, and electricity, you can also contact me directly. At present, the project is going to start within 1 month, and we will start drawing construction drawings soon. If you are interested, please send me your quote structure. What needs checking • ONAT and other majors DRC licensed certification • Architectural, structural, HVAC, plumbing/water and electrical construction drawings. Key tasks • Spot and correct dimension errors, note inconsistencies, missing call-outs and clashes between disciplines. • Verify that every detail aligns with current local building codes and local zoning laws. • Flag any wording that might be unclear to on-site crews or municipal reviewers. • Deliver a marked-up PDF set plus a concise summary report so the design team can revise quickly. Expectations • Solid background in real-estate documentation or construction engineering. • Proven experience proofreading large, technical drawing sets. • Familiarity with Congolese or comparable regional regulations a major advantage. • Timely, transparent communication throughout the review cycle. When you apply, please focus on your past work history handling similar large-scale projects; sample pages or before-and-after mark-ups are welcome. I’m ready to start as soon as I find the right specialist or studio and will supply the full drawing set under NDA.

Hi, I’m very interested in supporting your project. With a background in mechanical engineering and multidisciplinary coordination, I can assist with the review and coordination of architectural, structural, HVAC, plumbing, and electrical construction drawings for large-scale developments. I have experience identifying dimensional inconsistencies, coordination clashes, missing annotations, and constructability issues across drawing packages, while maintaining organized markups and clear revision reporting. I can provide structured PDF markups, concise review summaries, and coordinated feedback to help your team move efficiently toward construction. I’m also comfortable working within international standards and adapting to regional code requirements and approval workflows. My quote structure is typically based on drawing volume, discipline scope, and review stages, and I’d be glad to discuss a phased workflow once the package is available. Looking forward to collaborating with you.

Hi Yupeng Z., Last week I did a similar project and I am confident to handle this really well. My Questions. 1) Do you need certification under ONAT/ONAC for Republic of Congo, or DRC bodies, and which codes should I check against (Eurocodes, NF C 15‑100, ASHRAE, local zoning)? 2) What formats will you share (Revit/IFC/DWG/PDF), and is there a federated BIM model for clash detection? My Suggestions. 1) Use a single issue log with IDs, priority, owner, and status so revisions move fast and nothing is missed. 2) Lock a discipline code matrix (Arch/Struct/HVAC/Plumbing/Electrical) up front to avoid rework and unclear notes. My Execution Plan. - Sign NDA and review 5 sample sheets to align on quality bar. - Confirm codes, stamping/cert needs, and drawing list by discipline. - Set up CDE, sheet index, and issue tracker. - Run dimensional, note, and scope checks in Bluebeam Revu. - Do Revit/IFC coordination and Navisworks clash tests across trades. - Mark up PDFs with clear tags; flag unclear wording and missing call‑outs. - Deliver a concise summary report with prioritized fixes and code refs. - Hold review call; apply second‑pass updates and close out. - Provide compliance memo and a clear quote structure (per‑sheet + per‑discipline cap).

Hello, this is Maksim. I’m very interested in supporting your Republic of Congo development project and can assist with multidisciplinary construction drawing review and coordination for architecture, structure, HVAC, plumbing, and electrical systems. I have experience reviewing large technical drawing packages and identifying dimension conflicts, coordination clashes, missing annotations, and constructability issues before submission or construction. My workflow includes cross-discipline checking, code/compliance review, and preparation of marked-up PDF sets with concise revision reports to help teams resolve issues efficiently. I can support: • Architectural and structural drawing review • HVAC, plumbing, and electrical coordination • Clash and inconsistency detection • Code and constructability review • Clear markups and summary reports for rapid revision cycles For large projects, I typically structure pricing either: Per square meter (for full drawing review scope), or Per discipline/package based on sheet count and complexity. I can also work under NDA and maintain organized communication throughout the review process. Please share the drawing package scope, expected timeline, and required disciplines, and I can provide a detailed quote structure and estimated turnaround. I look forward to discussing the project further.

Hello, ✔️ Will the review scope include IFC/code compliance coordination only, or also constructability/value-engineering comments across disciplines? ✔️ Are the drawings being developed under DRC standards only, or should international references (IBC, Eurocode, ASHRAE, IEC, etc.) also be coordinated during checking? I have experience reviewing large multidisciplinary construction drawing packages including architectural, structural, HVAC, plumbing, and electrical coordination for real-estate and commercial developments. I can systematically check dimensions, annotations, discipline clashes, code alignment, missing call-outs, and drawing consistency while preparing clear marked-up PDFs and concise revision reports for fast team updates. My workflow focuses on clean communication between trades and reviewer-ready documentation to reduce RFIs, approval delays, and site conflicts before construction starts. I can also support full construction drawing production and coordination for large-scale developments, including structural and MEP systems, with organized QA/QC procedures throughout the review cycle. I am comfortable working under NDA and maintaining responsive communication during fast-track project delivery.
