I am laying out five vertical cylindrical tanks for oil storage and need a complete structural package for the circular raft foundations that will sit beneath each vessel. The design must be fully compliant with API 650 requirements for tank foundations, including all load combinations relevant to oil containment. At this stage I will forward the geotechnical report as soon as it is released, so please allow for one round of adjustments once the actual soil profile is known. Until then, work with clearly stated provisional assumptions, noting how they will be revised when the clay / sand / rock condition is confirmed. Deliverables I expect: • Sizing calculations and design notes (PDF + editable file) • Reinforcement layout, bar schedules and anchor-bolt plan in CAD (DWG) and PDF • Foundation plan and sections with all critical dimensions called out • Brief design summary highlighting API 650 clauses applied and any key checks (settlement, uplift, sliding, punching) I am happy with whichever analysis tools you normally use—SAFE, STAAD, Robot, hand checks—provided the method is transparent and traceable in the submission. Each raft must be ready for detailing and construction once the soil data is locked in.

Hello We read your requirement for a complete structural package for circular raft foundations supporting five vertical oil storage tanks under API 650 compliance. You mentioned the design must consider all oil containment load combinations. Our team has strong experience in structural design, foundation planning, and engineering calculations for complex construction projects. How would you like the provisional assumptions structured before the geotechnical report is released? We regularly prepare sizing calculations, reinforcement layouts, CAD drawings, and clear design documentation using professional analysis tools. Our team will deliver a transparent and traceable structural package ready for detailing and construction with revision support after soil data confirmation. Thanks

Having spent over a decade honing my skills in civil and geotechnical engineering, I'm both eager and qualified to tackle your Oil Tank Raft Foundation Design project. My extensive experience working with leading engineering firms in Pakistan, like NESPAK, has exposed me to a variety of design methodologies and analysis tools such as SAFE, STAAD, and Robot. Rest assured that I am well-versed in complying with the rigorous standards set by API 650. Moreover, my proficiency in software such as Civil 3D, AutoCAD, PLAXIS, and GeoStudio guarantees that I will be able to deliver the complete structural package you desire – whether it be reinforcement layouts or anchor-bolt plans – with exceptional efficiency and accuracy. My service doesn't stop at delivering designs; I'm also adept at creating clear, concise technical documentation that is crucial in ensuring hassle-free realization of any project. Your project's flexible provisional assumptions until the soil data can be confirmed will pose no problem for me. In fact, my academic background and teaching experience have trained me to rise above such challenges by being adaptable and proactive. I'm excited to discuss your project further and demonstrate why employing me for this undertaking would not only meet but exceed your expectations.

Hello, Thank you for sharing the details of your tank foundation project. I’m very interested in assisting with the structural design of the circular raft foundations for the five oil storage tanks. With experience in structural drafting and foundation detailing, I can prepare a clear and well-documented foundation package aligned with **API 650 requirements for tank foundations**. The design will consider all relevant load cases for oil containment, ensuring stability and structural reliability while remaining adaptable to the final geotechnical data. For this project I will provide: • **Foundation sizing calculations and design notes** with clearly stated assumptions for soil conditions • **Circular raft reinforcement layout**, bar schedules, and anchor-bolt plans prepared in **CAD (DWG + PDF)** • **Detailed foundation plans and sections** with all critical dimensions and reinforcement information • A concise **design summary** referencing the applicable **API 650 clauses** and key checks including settlement, uplift, sliding, and punching shear The initial design will be prepared using reasonable provisional soil assumptions, and I will include **one revision round** to update the calculations and detailing once the geotechnical report is available. All deliverables will be organized so the foundations can move smoothly into **detailing and construction once soil data is confirmed**. Best regards, Mohamed Fathy

Hello I’ve worked on tank foundation design and can prepare a complete structural package for the circular raft foundations in line with API 650 requirements and standard oil storage loading conditions. I’ll develop the design using clearly stated provisional geotechnical assumptions, then update the calculations and drawings once the soil report is issued, including one round of revisions. The final package will include traceable calculations, reinforcement and anchor-bolt layouts, foundation plans and sections, and a concise design summary covering the key checks for settlement, uplift, sliding, and punching. THank you.
