PileCap

Take the guesswork out of deep foundation engineering.PileCap is a powerful structural engineering utility built for civil, structural, and geotechnical engineers. Designed specifically to streamline foundation analysis and layout workflows, the app automates the engineering verification matrix for both Driven Square Piles and Bored Cast In-Place Piles directly from your Android device.Simply input your layout parameters, applied vertical and lateral load combinations, structural safety factors, and geotechnical soil properties to instantly evaluate standard pile cap configurations (PC1 through PC6) against rigorous design standards.Key Features:Dual-Module Engineering Core: Full support for 400x400 mm driven square pre-cast piles as well as Ø 400 mm and Ø 500 mm circular bored cast in-place systems.ACI 318-19 Compliant Verification: Automated calculations running real-time, multi-equation punching shear stress checks (Section 22.6), size effect factors ($\lambda_s$), and one-way beam shear calculations (Section 22.5).Advanced Geotechnical & LRFD Matrix: Rigid-cap pile group reaction engine ($R = P/n \pm M_z \cdot x/\Sigma x^2 \pm M_x \cdot z/\Sigma z^2$) implementing service-level ASD geotechnical limitations alongside structural LRFD scaling factors.Dynamic SVG Structural Layouts: Instant vector graphic generation showing exact edge clearances (1.0D), pile center-to-center spacing constraints (3.0D minimum), pile cap boundaries, and pedestal anchor zones.Responsive State Architecture: Built using an immutable domain state model that recalculates and updates design telemetry instantly as you adjust structural loads.Transient Load Safeguards: Integrated protections against improper single-pile moment dissipation, complete with clear visual pass/fail indicator cards.Who is this for?Structural Engineers: Quickly evaluate foundation options or double-check desktop analysis output (such as Foundation 3D or SAFE) while on-site or during technical review meetings.Geotechnical Engineers: Verify pile reaction limits against site soil report parameters immediately.Project Managers & Field Inspectors: Instantly visualize required footprint dimensions and calculate structural concrete volumes ($m^3$) needed for standard configurations.Turn complex foundation parameters into clean, visual code compliance data.
