Fire Alarm System Designer and Control & Automation Engineer with experience in 190+ U.S.-based fire alarm projects. I specialize in complete fire alarm system design for residential, educational, commercial, industrial, military, and specialized facilities, working in accordance with NFPA 72, NFPA 101, applicable ICC codes, project specifications, and manufacturer requirements. My experience includes complete fire alarm design packages, device layouts, floor plans, riser diagrams, wiring diagrams, battery calculations, voltage drop calculations, NAC and SLC circuit design, sequences of operation, and technical design reviews. I also have experience with specialized fire alarm applications, including linear heat detection using Protectowire and SafeCable, smoke control systems, smoke compartments, AOR systems, and two-way communication systems. I have worked with fire alarm systems and equipment from multiple manufacturers, including Siemens, Notifier, Fire-Lite, Gamewell-FCI, Farenhyt, Edwards, Kidde, Mircom, Monaco, Autocall, and Potter. In addition to system design, I currently perform technical reviews of fire alarm projects, identifying design deficiencies, calculation issues, coordination problems, and potential code compliance issues before project delivery. Services I can provide: • Complete fire alarm design and shop drawings • Fire alarm device layouts and circuiting • Riser and wiring diagrams • Battery calculations • Voltage drop calculations • NAC and SLC circuit design • Sequence of operations • Drawing revisions and redlines • Technical design review • AutoCAD and FireCAD drafting I am available for individual projects, overflow design support, and ongoing collaboration with fire alarm contractors, low-voltage integrators, and engineering teams. Note: PE/NICET stamps, professional seals, and AHJ approvals are not included in my services.

I am a German-qualified electrical engineer (B.Eng., Electrical Engineering - Energy and Information Technology) with more than seven years of experience in electrical MEP design for buildings. I work remotely as a design and BIM resource for MEP consultants, architects and contractors, producing complete and coordinated electrical documentation under the direction of your Engineer of Record. My day-to-day work covers power distribution, from service, feeder and branch layouts to load and short-circuit calculations, voltage drop, cable and conduit or tray sizing, panel schedules and single-line diagrams. On the lighting side I handle interior, exterior and egress lighting with illuminance calculations and layouts in DIALux evo. I also cover low-voltage and ELV systems such as telecom and data, fire alarm layouts, access control and security, together with earthing and lightning protection. What I hand over are full construction document sets with plan drawings, schedules, details, specifications and tender documents. I model in Revit MEP, run clash detection in Navisworks and exchange IFC. I am equally comfortable taking over incomplete or inconsistent drawings, checking them for code compliance, constructability and coordination conflicts, and reissuing a clean, buildable set. I work through schematic design, design development and construction documents, which corresponds to German HOAI phases 1 to 8, including as-built and revision documentation. I design to international standards and adapt to the code framework of each project, including NEC (NFPA 70), NFPA 72, IES, ASHRAE 90.1, IECC, IEC, BS and the European VDE, DIN and EN standards. Project experience covers hospitals and clinics, government and police facilities, offices, hotels, schools and industrial and logistics buildings, among them a police headquarters, a US clinic, a university hospital, an ICE rail depot, a steel production facility and a four-star hotel. Software I use daily: Revit MEP, AutoCAD, Navisworks, DIALux evo, Simaris Design, Caneco BT and PV*SOL. I work fully remote with fast turnaround, I am fluent in English and German, and I am available for one-off packages as well as ongoing overflow capacity.

I provide independent electrical design reviews for villas, residential developments, schools and other buildings. I help consultants, contractors and property owners check existing designs before procurement and construction, with clear calculation checks, annotated drawing comments and a prioritized review register. As a senior electrical engineer with experience in electrical design, supervision and consultancy, my focus is the engineering basis behind the drawings. My electrical review scope includes: • Load calculations, demand assumptions and panel schedules • Cable and circuit-breaker sizing and voltage-drop verification • Single-line diagrams and power distribution • Lighting and power layouts • Earthing and grounding arrangements • Consistency between drawings, calculations, specifications and bills of quantities • Electrical material submittals against project requirements For each finding, I identify the issue, its technical basis, the required corrective action and any information needed to close the comment. A follow-up review of the designer’s responses can be included in the agreed scope. This service covers electrical design checking. The applicable standards, local requirements, available documents and deliverables are agreed before work starts. Final design responsibility and statutory approval remain with the appointed designer and locally authorized engineer. B.Sc. in Electrical Engineering, University of Baghdad, 2003. Available for remote project-based and ongoing collaboration using AutoCAD drawings, PDF drawing sets and Excel calculation schedules. Send your drawing set and calculation package so we can define the review scope and deliverables.
