I already have the architectural plans and elevations for a mid-size residential project. What I now need are the full Mechanical, Electrical, and Plumbing layouts completed so the drawings can move straight into construction. The blueprints should include full architectural details and specific features such as: - Electrical schematics - Plumbing layout - HVAC system plans Ideal skills and experience: - Proficiency in architectural design software - Experience in creating detailed blueprints - Knowledge of electrical, plumbing, and HVAC systems - Attention to detail and accuracy If you have experience delivering complete residential MEP sets and can demonstrate that in your portfolio, I’d be happy to hear how soon you can begin.
I need a skilled professional to draw up onsite mechanical MEP markups based on existing digital blueprints. The project includes: - HVAC systems - Ductwork layout - Equipment placement Ideal Skills and Experience: - Proficiency in MEP design and markup - Experience with HVAC systems - Strong understanding of ductwork and equipment placement - Ability to work from digital blueprints and ensure accuracy Looking for someone with a keen eye for detail and a strong background in mechanical engineering or related fields. Please provide samples of previous work.
I am fitting out a 5,200 sq ft unit that will operate as a clinic and I need a complete drawing package that the local health authority can approve without revisions. The scope begins with the architectural layout—every wall, door, and piece of furniture must be shown exactly as the authority requires—then moves straight into the full MEP design. First, I need the submission set that secures the clinic licence: floor plans, reflected ceiling plans, furniture layout, and any other sheets the authority checklist demands. Once that approval is in hand, we will move to the coordinated MEP package covering HVAC, plumbing, electrical, and the related ceiling modifications. All work has to follow the local health authority standards; familiarity with their usual comments and red-line...
I’m working on an ongoing residential project in the City of West Covina and need our current Title 24 California Energy Report (CF1R) brought up to the 2026 standards. The existing CF1R package is complete through the previous code cycle, and I already have all the underlying energy-efficiency measure data on hand. Your task is to revise the energy efficiency measures and the compliance documentation so the report aligns with the 2026 Title 24 requirements, including any newly adopted prescriptive or performance criteria. All utility data sections are already in order, so the focus will be on recalculating, re-narrating, and re-formatting the portions that reference measures such as envelope performance, HVAC, DHW, and lighting, then updating the corresponding compliance forms. De...

I need a mechanically minded partner who can step in every week to prepare complete HVAC design packages for single-family and multi-family homes. Each assignment will be billed hourly; this is steady, week-to-week work rather than a one-off project. What I routinely hand over are architectural plans and a brief on the climate zone and building envelope. From there, you produce: • Duct layout drawings • Piping schematics • Equipment placement plans All drawings must reflect a heat-pump system and meet the Florida Energy Code R405 method (or equivalent) for residential structures. Alongside the drawings I also rely on you for accurate load calculations—sensible/latent and peak demand—using accepted methods so the design is ready for permit submittal. ...
I need a digital twin that zeroes-in on my building’s energy performance. Right now I only have partial data—BMS exports, sub-metering on a handful of panels, and monthly utility bills—so the model must be able to start with what’s available, validate any gaps, then scale as more sensors come online. Primary improvement targets: • Heating and cooling systems • Overall energy consumption The twin should connect to the existing BIM (Revit) files, ingest the live and historical data, and run calibrated simulations—EnergyPlus or an equivalent physics-based engine is fine—so I can visualise real-time KPIs and generate “what-if” scenarios for retrofit ideas. I’m interested in clear, actionable outputs such as predicted savings...
