Fence Foundation & Wind Load Calculations
Budget: $30 – $250 USD
An HSIC-Class metal fence with an integrated gate is scheduled for installation on a rural site. I will supply the current drawings, material specs, and every standard that must be observed; your task is to verify the whole foundation concept and document the structural adequacy.
Scope
• Perform a full wind-load analysis on the fence and gate, using the design wind speed stated in the material I provide, then convert pressures into line and point loads.
• Check overturning, sliding, and bearing stability for each post footing and for the gate support structure.
• Size or confirm concrete footing dimensions, reinforcement, and embedment details.
• Summarise all safety factors, governing load cases, and reference clauses from the supplied standards.
Deliverables
1. Calculation report (PDF) with clear inputs, step-by-step formulas, and final utilisation ratios.
2. Editable spreadsheet or calculation sheet (Excel / MathCAD) so values can be updated later.
3. Mark-ups on the original drawing set showing any footing or reinforcement changes.
Acceptance criteria
• Load combinations match the provided code.
• Utilisation ratios ≤ 1.0 for all checks.
• Footing geometry fits the site constraints noted in the drawings.
Please indicate the software you intend to use (e.g., STAAD, Robot, SAP2000, hand-calc spreadsheet) and your typical turnaround time once you have received the design package.
The design must comply with SBC 301/304, BS 8110-1997, BS 1722 Part 10, and ASTM (A-53/C39) standards, utilizing criteria of 54 m/s wind velocity, 150 kN/m² soil bearing, C35 concrete grade, and a 1.5 safety factor against overturning and slip
Complete wind load calculations and load combinations shall be provided with reference to the adopted code.
Complete foundation stability calculations shall be submitted, including overturning, sliding, bearing, and uplift checks.
Foundation reinforcement details and material specifications shall be provided.
Typical sections/details used in the calculations shall be included in the calculation report with reference to the relevant drawings.
The structural design must adopts a minimum safety factor of 1.5 for overturning and slip (ULS)
Please include detail structural strength calculation for the adopted post. Show the utilization of the post
the soil bearing capacity of SLS and ULS increased the allowable soil bearing pressure which is taken as 150Kpa.
The design wind speed for the gate is considered as 54 m/s and for the foundation base design wind speed is 44 m/s which mis aligns togather, and does not meet the project design guidelines as per EPC contract. The design wind speed is to be 56.5m/s. epc to revise the calculations accordingly
