Understanding these common corrections and how to resolve them can streamline the approval process. What Are Typical Corrections Found in MEP Drawings? Common plan check corrections for MEP drawings frequently involve non-compliance with specific code requirements or missing details. These can include: Mechanical Systems: Issues related to HVAC system design compliance with the California Mechanical Code (CMC). Electrical Systems: Corrections based on the California Electrical Code (CEC) for circuit sizing and panel schedules. Plumbing Systems: Discrepancies in piping layouts per the California Plumbing Code (CPC). Energy Compliance: Adjustments for Title 24 Part 6 Energy Code requirements. How to Address Mechanical Plan Check Corrections? Common mechanical corrections require: Ensuring HVAC load calculations are detailed and align with CMC standards. Providing duct sizing and layout details. Including ventilation requirements under CBC guidelines. Address these by revising calculations and providing clear ductwork drawings. Addressing Electrical Plan Check Corrections Effectively Typical electrical plan corrections may demand: Confirmation of circuit loads and panel schedules matching CEC requirements. Specifications for grounding and bonding systems. Detailed lighting load calculations as per CBC Chapter 11B for accessibility. To resolve these, verify load calculations and add detailed specifications to plans. Resolving Plumbing Plan Check Corrections Plumbing corrections often involve: Adjustments to pipe sizing to comply with CPC standards. Ensuring correct fixture unit calculations. Properly detailing vent and trap details. Reviewing and accurately calculating fixture units and pipe layouts are essential steps. Real-World Example: City Building Department Correction Letter & Solution Let's explore a sample correction letter from the City of San Diego: The HVAC system must comply with CMC Section 403.2. Please update Sheet M-15 to reflect required ventilation changes. Electrical panel schedules shown on Sheet E-2 lack compliance with CEC Article 220. Revise to display actual loads. Plumbing fixture calculations on Sheet P-4 do not meet CPC Table 610.3 standards. Adjust and resubmit. The Engineering Solution Step 1: Our team recalculated ventilation requirements per CMC Section 403.2 and updated Sheet M-15 accordingly. Step 2: We verified and recalculated electrical loads and revised Sheet E-2 to align with CEC Article 220. Step 3: We adjusted fixture unit calculations on Sheet P-4 according to CPC Table 610.3 and resubmitted the details.
