Finite Element Analysis (FEA) Report for Pedestrian Access Hatch Cover (MS + Stainless Steel)

Project Description We are looking to appoint an experienced Structural / Mechanical Engineer to carry out a Finite Element Analysis (FEA) and issue a formal calculation report for a recessed access hatch cover designed for pedestrian load only. The design is already completed. The scope of work is analysis and verification only, not design development. The access hatch is a large-format recessed cover, approximately 3000 mm × 3000 mm, fabricated using a combination of Mild Steel (MS) structural members and Stainless Steel cover plates. Scope of Work The consultant will be required to: Review Provided Design Data 2D / 3D drawings (DWG / PDF) Material specifications Section details and support conditions FEA Structural Analysis Create an FEA model of the access hatch system Apply appropriate boundary conditions and supports Perform linear static structural analysis Evaluate: Von Mises stress Maximum deflection Stress distribution Critical stress locations Load Case Definition (Pedestrian Load Only) Uniformly Distributed Load (UDL) Localized load (if required by standard) Self-weight (dead load) Compliance Check Against Applicable Standards Compare stresses and deflections against allowable limits Confirm whether the system is SAFE / NOT SAFE Provide utilization ratios where applicable FEA Report Submission The final report must include: Project description Applicable standards Material properties Load assumptions Boundary conditions Mesh details Stress & deflection results Color contour plots / simulation screenshots Summary conclusion confirming compliance Applicable Design Standards The analysis must comply with internationally recognized standards, such as: EN 1991-1-1 (Eurocode 1) – Actions on structures EN 1993-1-1 (Eurocode 3) – Steel structures OR BS EN 124 (for access covers – pedestrian class reference) OR ASCE 7 – Minimum Design Loads for Buildings (if using American standards) The engineer must clearly state which standard is adopted and justify load assumptions. Design Load Requirement (Pedestrian Only) This access hatch is NOT designed for vehicular traffic. Required Pedestrian Load (Minimum): Uniformly Distributed Load (UDL): 5.0 kN/m² (minimum pedestrian loading as per Eurocode / BS practice) Point Load (if required by chosen standard): Typically 1.5–2.0 kN applied at the most unfavorable location The consultant may recommend additional load combinations based on the selected standard. Hatch Description Type: Recessed access hatch cover Overall size: Approx. 3000 mm × 3000 mm Use: Internal / external pedestrian access Material: Structural frame: Mild Steel Cover plate / visible elements: Stainless Steel (grade to be confirmed) Support: Hatch supported on surrounding concrete / steel structure (details provided) Deliverables Signed & stamped FEA report (PDF) FEA screenshots / contour plots Clear statement of compliance Editable source file (optional but preferred) Software Requirements The analysis must be performed using recognized engineering software such as: ANSYS Abaqus SolidWorks Simulation STAAD / similar professional tools Required Freelancer Profile Structural or Mechanical Engineer Proven experience with FEA of steel structures Experience with access covers / hatches / plates Ability to work with Eurocode / BS / ASCE standards Previous FEA report samples preferred Important Notes This is analysis only – no redesign required All drawings and inputs will be provided after award Report must be suitable for consultant / client submission
