- TURNKEY, ONE-STOP-SHOP for new building construction and renovation Electrical Drawings and Specifications design that you can trust to be done accurately and thoughtfully the first time - DESIGNED OVER 1,500 ELECTRICAL DRAWINGS AND SPECIFICATIONS PACKAGES from start-to-finish for projects located across 17 different states - OVER 15 YEARS OF EXPERIENCE in electrical system design for new building constructions, renovations and modifications, including 9 years total of remote/satellite work - WORKED FOR THREE PROFESSIONAL ELECTRICAL ENGINEERING FIRMS located in California, Florida, and Georgia under direct supervision by and in collaboration with experienced Professional Engineers We all know that searching on these freelance sites means you have to sort through so many profiles, and that just a few simple questions are almost always at top of mind: 1) Does this person behind the profile have the actual expertise and experience needed to meet the high standards I have for this project? 2) Does this person communicate clearly and effectively, and is he/she accessible, available, and responsive to me? 3) Will it truly be worth it to farm out projects to a freelancer, or will the investment of my time and money be better served by just hiring someone in-house or maybe doing it myself, instead? Let me show you that I can deliver on all three of the above questions for your project and prove to you that you've made the right decision by hiring me to work remotely on your new building construction or renovation design documents. I'll design the Electrical Drawings and Specifications for each project from inception to completion or based on our specific, mutually agreed upon scope of work... Only a Professional Engineer's review, then seal, signature and date is required upon completion of the project. I'll, of course, communicate closely with you to ensure the design package is produced precisely and delivered in a timely manner, so that the entire design process meets the Engineer's, Architect's, and Client's highest expectations and so that each project's deadlines are met. I'll confirm that the design is in compliance with all applicable state and local codes and Authorities Having Jurisdiction. I'll join design team conference meetings and coordinate with other trades, manufacturer representatives and project decision makers, so clear communication happens. I'll meet project milestone deliverables and send progress set submittals, for reliable and accurate project execution. You can free up your time and offload the vast majority of the electrical design project to me, knowing that each project will be custom, individually tailored, and given the expertise, thought, and attention to detail that it deserves. I take a lot of pride in my work, and my constant goal is for that to be evident in the Plans I produce. **I can use my own extensive library of industry-recognizable Electrical and Low Voltage System CAD symbols, details, riser and one-line diagrams, schedules, general notes, etc. with corresponding drafting standards and Plan and/or Booklet Specifications... or I can quickly learn to adopt and use your firm's templates.

My name is Mohammed Abul Hassan. I have graduated at College of the North Atlantic – Qatar studying advanced diploma program in Mechanical Engineering Technology program. At present, i am pursuing Bachelor of Science in Mechanical Engineering at Qatar University. Most people in the world have some goals in life. My aim in life is to become a mechanical design engineer. After I graduated high school, I became certain that I will pursue my higher education in mechanical engineering. The reason to study mechanical engineering is that, when I was in high school I was interested in Applied Math’s and physics. I like to apply theory which I studied in physics to solve real life problems. As a result, I have decided to study mechanical engineering. Moreover, I want interested to build hand-working skills in mechanical engineering. For this reason, I study at College of the North-Atlantic Qatar which is Canadian technical college. I have completed my advanced diploma in Mechanical Engineering Technology (industrial maintenance). In this diploma, I have learned a lot of industrial maintenance for example- reliable center maintenance, how the power plant system works, how to do maintenance in machinery equipment’s etc. Moreover, in final year I have learned how to build product from scratch. In my capstones project I build a hydraulic book lifting trolley. At first, I have done to research for the need of project. After that I calculated and design the model in 3-D software Catia V5. After finishing design I fabricated the project using college resources such as welding, fastening etc. These all techniques of fabrication I have learned in my diploma program. From this project I am interested to make career in design and manufacturing. After completion Diploma, I progressed towards B.Sc. Mechanical Engineering Degree completion at Qatar University. As a Mechanical Design Engineer, I have design and fabricated numerous projects, some of them highlighted below: -The aim of project is to design and simulate a solar powered water distillation system for rural communities in Somalia. The system consists of the evaporator, condenser, and storage tank for salty water, storage tank for distilled water, filter, pump and solar collector -The aim is to design a greenhouse that maintains the required climate to grow to tomatoes in hot and arid environments such as Qatar. The required climate includes the temperature, relative humidity, ventilation and carbon dioxide, lighting and thermal radiation, and so forth. The design is meant to meet the conditions at lower energy consumption and initial and operating cost so that to produce tomatoes that will be used for resale at a reasonable price and make profit. The design should also be reliable, have back-up systems, and be maintainable. Growing tomatoes and other crops in Qatar’s environment is important to increase food resources and production. -Aim of project describes computational and experimental investigation on the response of thin wall structures for energy absorption of car crash boxes. In this project, the tubes subjected to quasi-static axial loading. Many different cross-sectional structures have been studies to find optimal configuration for energy absorption. Initially, the Finite Element Analysis (FEA) model has been developed for different structures. From FEA model, Specific Energy Absorption (SEA) and Peak force has been estimated for different cross-sectional structures. To verify these performance parameters, quasi-static axial loading has been performed experimentally. Both foam-filled and without foam on different cross-sectional structures are implemented to study their effects on the performance parameters. The study used the aluminum alloy as a material to investigate the ability of using aluminum alloy in the energy absorption structures since the aluminum has lighter weight.

Started working with CAD back in late 2010 at a fire alarm in Dallas Tx. There I re-drew the building layout from engineered drawings and designed fire alarm systems from a simple finish out to a complete install. I then started drafting for a family owned engineering company in Tulsa Ok. The company works in the gas and oil industry which as familiarized me in p&id's, panel layouts, instrumentations, as well as mechanical piping. I believe I have the skills to draft anything from scratch given dimensions and or specific details. I enjoy learning new things and the challenge to complete projects to the best of my abilities.
