LEED v4.1 BD+C — Construction-Phase Credits

LEED certification requires active participation from the construction team. The superintendent's role is critical for several prerequisites and credits during the construction phase. The LEED coordinator manages documentation and submittals, but the superintendent ensures field compliance.

Cross-Reference: For detailed credit-by-credit requirements, documentation checklists, and common pitfalls, see references/leed-construction-guide.md.

SS Credit: Construction Activity Pollution Prevention

Requirement: Erosion and sedimentation control plan conforming to EPA Construction General Permit OR local equivalent.

Cross-Reference: BMP installation and maintenance procedures are in field-reference/references/bmp-field-guide.md. This credit requires the BMPs to be installed AND documented per the SWPPP.

Documentation Required:

• SWPPP document (on-site copy)
• Weekly inspection logs with photos
• Corrective action records
• BMP maintenance logs

MR Credit: Construction & Demolition Waste Management

Prerequisite (MR Prerequisite): Construction waste management plan required for all LEED projects.

Credit Thresholds:

Waste Management Plan Requirements:

1. Waste streams identified: Concrete/masonry, wood, metals, drywall, cardboard, plastic, mixed C&D
2. Diversion strategies: On-site segregation vs. commingled recycling facility
3. Hauler certifications: Recycling facility documentation, diversion rate verification
4. Tracking method: Monthly weight tickets from haulers, diversion rate calculation
5. Reporting: Monthly diversion reports, cumulative project total

Diversion Rate Calculation:

Diversion Rate = (Total Recycled Weight) / (Total Recycled + Total Landfilled) x 100%

Example:
  Recycled: 85 tons (concrete 40T, metals 20T, wood 15T, cardboard 10T)
  Landfilled: 25 tons (mixed debris)
  Diversion Rate = 85 / (85 + 25) x 100% = 77.3% (qualifies for 2 points)

Superintendent Responsibilities:

• Enforce segregation on site (labeled dumpsters/bins)
• Verify hauler certifications
• Collect and file weight tickets
• Calculate monthly diversion rate
• Report to LEED coordinator

EQ Credit: Construction Indoor Air Quality Management

Requirement: SMACNA IAQ Guidelines for Occupied Buildings Under Construction (ANSI/SMACNA 008-2008) during construction.

Key Field Requirements:

HVAC Protection Protocol:

1. Before ductwork installation: seal all openings with plastic caps or tape
2. During construction: keep return air grilles covered
3. Use temporary filtration (MERV-8 minimum) at all return openings
4. Before occupancy: replace all filters with design-specified MERV rating
5. Document with photos at each stage

Construction IAQ Testing (Option 2):

• Conduct air quality testing after construction, before occupancy
• Test for: formaldehyde, TVOC, PM10, carbon monoxide, 4-PCH (for carpet)
• Testing must meet LEED thresholds (formaldehyde < 27 ppb, TVOC < 500 ug/m3)
• Flush-out alternative: 14,000 CF of outdoor air per SF of floor area

Low-Emitting Materials Tracking

LEED EQ Credit: Low-Emitting Materials requires tracking VOC content of installed products.

Tracking Process:

1. Collect product data sheets (PDS) and safety data sheets (SDS) for all interior products
2. Verify VOC content against LEED limits
3. Reject non-compliant products BEFORE installation
4. Maintain product tracking log with: product name, manufacturer, VOC content, area installed, date
5. File documentation for LEED submittal

MR Credit: Sustainable Purchasing — EPDs and HPDs

EPDs (Environmental Product Declarations):

• Third-party verified lifecycle assessment of product environmental impact
• Products with EPDs earn credit toward LEED MR Credit
• Types: Industry-wide EPD (generic), Product-specific EPD (verified by third party)
• Priority: Product-specific EPD with third-party verification = most credit value

HPDs (Health Product Declarations):

• Disclosure of product ingredients and health hazards
• Products with HPDs contribute to LEED Credit: Building Product Disclosure
• Superintendent should request HPDs from manufacturers at submittal stage

Superintendent Action Items:

• Flag submittal packages that include EPDs/HPDs (coordinate with LEED coordinator)
• Verify EPD/HPD documentation is filed with product data
• Track which products have EPDs/HPDs in material log

LEED Documentation Summary

SWPPP Administration

Permit Lifecycle

The SWPPP (Stormwater Pollution Prevention Plan) is required under the Clean Water Act for construction sites disturbing 1 acre or more. The NPDES Construction General Permit (CGP) governs compliance.

Permit Cycle:

NOI Filed → Permit Issued → Construction Begins → Compliance Monitoring → Construction Complete → Site Stabilized → NOT Filed
  │              │                    │                      │                        │                  │              │
  │              │                    │                      │                        │                  │              └─ Record retention
  │              │                    │                      │                        │                  └─ Final stabilization
  │              │                    │                      │                        └─ Punch-out BMPs
  │              │                    │                      └─ Inspections, corrective actions, reporting
  │              │                    └─ Install BMPs per SWPPP plan
  │              └─ Post permit on-site (NOI receipt, SWPPP available for review)
  └─ Submit 14+ days before land disturbance begins

Key Terminology:

• NOI: Notice of Intent — filed with EPA/state before construction begins
• NOT: Notice of Termination — filed after final stabilization achieved
• CGP: Construction General Permit — the NPDES permit for construction stormwater
• Final Stabilization: 70% perennial vegetative cover OR permanent cover (pavement, buildings)

SWPPP Document Requirements

The SWPPP must contain:

1. Site Description:

   • Project location, size, and nature of construction
   • Existing site conditions and receiving waters
   • Sequence of major construction activities

2. Site Map:

   • Property boundaries and disturbed area limits
   • Drainage patterns and discharge points
   • BMP locations by construction phase
   • Receiving waters and buffer zones
   • Stockpile locations
   • Construction entrance locations

3. BMPs by Phase:

   • Phase 1 (Site Prep/Grading): Perimeter silt fence, stabilized construction entrance, inlet protection, temporary seeding
   • Phase 2 (Utilities/Foundation): Dewatering controls, concrete washout, material storage BMPs
   • Phase 3 (Vertical Construction): Dust control, material staging, waste containment
   • Phase 4 (Final Grading/Stabilization): Permanent seeding, sod, mulch, final inlet protection removal

4. Inspection Schedule and Procedures

5. Maintenance Procedures for Each BMP

6. Responsible Parties (SWPPP administrator, inspectors, emergency contacts)

7. Spill Prevention and Response Plan

8. Pollution Prevention Measures (concrete washout, chemical storage, equipment fueling)

Inspection Requirements

Standard Inspection Frequency:

Inspection Checklist Items:

Inspector Qualifications

The SWPPP inspector must be a qualified person who:

• Has knowledge of NPDES CGP requirements
• Can identify BMP deficiencies and required corrective actions
• Is familiar with the site-specific SWPPP
• Has authority to modify BMPs as conditions change
• Many states require specific certification (e.g., CPESC, CESSWI, QCI)

                        Document repair
                        in SWPPP log

Corrective Action Requirements:

1. Identify: Note deficiency during inspection (exact location, description, severity)
2. Document: Photo with date stamp, written description, severity rating
3. Repair: Initiate repair within 24 hours of identification (before next rain event if possible)
4. Re-Inspect: Verify repair effectiveness within 24 hours of completion
5. Log: Record corrective action in SWPPP inspection log with dates and photos

Record Retention

• Minimum 3 years after NOT (Notice of Termination) is filed
• Retain all inspection reports, corrective action logs, photos, weight tickets
• Some jurisdictions require longer retention (check local requirements)
• Digital records acceptable if properly backed up and accessible

Common SWPPP Violations and Penalties

State penalties may be higher. Some states have independent enforcement with additional fines. Many violations are discovered during state or EPA inspections triggered by citizen complaints or aerial observation.
