Condensate & Sanitary Drainage System – Dynamic Fittings + Typical Installation Details (Gulf/KSA Standards)
This post provides a complete resource pack for MEP draftsmen and site engineers working on sanitary drainage and HVAC condensate drainage systems in the Gulf region. You’ll get dynamic DWG fittings, typical installation details, and ready notes aligned with common KSA/Gulf standards, so you can produce professional shop drawings faster and with fewer errors.
What’s Inside
- Condensate Drainage System (HVAC): Traps, air breaks, slopes, insulation notes, and connection details from AHU/FCU drip trays to floor drains or manholes.
- Sanitary Drainage System: Layouts for waste (W) and soil (S) networks, venting approaches, cleanout spacing, and manhole tie-ins.
- Typical Installation Details (DWG + PDF): Floor drain assembly, cleanout detail, P-trap with access, pipe supports/hangers, backwater valve, grease interceptor (where applicable), and sleeve/penetration details.
- Dynamic Fittings (AutoCAD): Parametric bends, tees, reducers, wyes, traps, couplings, and victaulic-style components with size ranges (e.g., 15–300 mm) and flip/rotation controls.
- Isometric Views: Quick-reference isos showing slopes, invert levels, and vent take-offs to help junior staff understand coordination.
Key Highlights
- Gulf/KSA-aligned drafting notes: Clear text for slopes (e.g., 1%–2%), trap seal depths, and cleanout locations as typically accepted by local authorities.
- Annotation-ready blocks: Dynamic labels, callouts, and leaders included for rapid documentation.
- Layer & LTSCALE discipline: Suggested layers (e.g., DRN_W, DRN_S, DRN_V, HVAC_COND) and linetypes to keep drawings BIM/coordination friendly.
- Quality control checklist: Built-in QC notes to verify slope arrows, vent continuity, and trap priming (if required by spec).
Typical Details Included
- Condensate from FCU/AHU: Trap sizing table, air break to floor drain, insulation thickness note, and termination options.
- Floor Drain (FD) Assembly: Strainer/grate types, trap primer (if specified), waterproofing upstand, and connection to branch.
- Cleanout (CO) & Access: Wall/floor CO detail, recess cover, spacing guidance (e.g., at base of stack, every 15 m or per spec).
- Pipe Supports: U-bolts/clamps, hanger spacing guide, vibration isolation where connected to HVAC equipment.
- Venting: Relief vent at long branch, stack vent/vent through roof (VTR) detail with termination cap.
- Manhole/Inspection Chamber: Invert level callout example, benching and channel note, watertight cover.
How to Use the Dynamic Fittings
- Insert > Block and set Annotative = Yes for text-ready callouts.
- Use grips to flip/rotate and stretch to change nominal size.
- Keep system slope as property; arrows auto-update.
- All blocks use consistent insertion points to snap cleanly with polylines.
- Best-Practice Notes (Site & Shop Drawing)
- Maintain minimum 1:100 slope (1%) for small-diameter sanitary; verify spec for fixture branches.
- Provide trap seal protection (primer or deep seal) to avoid evaporation in hot climates.
- Avoid direct condensate connection to sanitary without air gap/air break per local authority requirements.
- Locate cleanouts at every change in direction >45°, base of stacks, and at regular intervals.
- Coordinate invert levels early with structural to prevent clashes and ensure gravity flow.
File Info
- Format: DWG (2018+), PDF (vector)
- Contents: Dynamic blocks, typical details, example isometrics, text styles, layer template (CTB guidance included)
- Sizing: 15–300 mm coverage for common fittings; metric units (mm)
Who Is This For?
- MEP draftsmen and junior engineers working in KSA/UAE/Qatar projects
- Contractors who need ready typicals for submittals
- Trainers/mentors helping freshers understand drainage coordination
FAQ
Q: Are these details approved by local authorities?
A: They follow common practice in Gulf projects; always align with the project specification and the authority’s latest regulations before submittal.
Q: Can I modify the dynamic fittings?
A: Yes—parameters are editable. You can add sizes, adjust labels, or remap layers as needed.
Q: Do the files include isometric examples with invert levels?
A: Yes, sample isos with invert callouts and slope arrows are included to guide your own drawings.
