<br />8. ONLY CHAMBERS THAT ARE APPROVED BY THE SITE DESIGN ENGINEER WILL BE ALLOWED. UPON REQUEST BY THE SITE DESIGN
<br />ENGINEER OR OWNER, THE CHAMBER MANUFACTURER SHALL SUBMITA STRUCTURAL EVALUATION FOR APPROVAL BEFORE
<br />DELIVERING CHAMBERS TO THE PROJECT SITE AS FOLLOWS:
<br />• THE STRUCTURAL EVALUATION SHALL BE SEALED BYA REGISTERED PROFESSIONAL ENGINEER.
<br />+ THE STRUCTURAL EVALUATION SHALL DEMONSTRATE THAT THE SAFETY FACTORS ARE GREATER THAN OR EQUAL TO 1.95 FOR
<br />DEAD LOAJD AND 1-75 FOR LIVE LOAD, THE MINIMUM REQUIRED BY ASTM F2787 AND BY SECTIONS 3 AND 12-12 OF THE AASHTO
<br />LRFD BRIDGE DESIGN SPECIFICATIONS FOR THERMOPLASTIC PIPI=.
<br />■ THE TEST DERIVED CREEP MODULUS AS SPECIFIED IN ASTM F2418 SHALL BE USED FOR PERMANENT DEAD LOAD DESIGN
<br />EXCEPT THAT ITSHALL BE THE 75-YEAR MODULUS USED FOR DESIGN.
<br />9. CHAMBERS AND END CAPS SHALL BE PRODUCED AT AN ISO 9001 CERTIFIED MANUFACTURING FACILITY-

<br />IMPORTANT -NOTES FOR THE RIDGING AND INSTALLATION OF MC-45( CHAMBER SYSTEM
<br />t STORMTECH MC4500 CHAMBERS SHALL NOT BE INSTALLED UNTIL THE MANUFACTURER'S REPRESENTATIVE HAS COMPLETED A
<br />PRE -CONSTRUCTION MEETING WITH THE INSTALLERS.
<br />2. STORMTECH MC-4500 CHAMBERS SHALL BE INSTALLED IN ACCORDANCE WITH THE "STORMTECH MC-35001MCASM CONSTRUCTION GUIDE'-
<br />3. CHAMBERS ARE NOT TO SE SACKFILLED WITH A DOZER OR EXCAVATOR SITUATED OVER THE CHAMBERS.
<br />STORMTECH RECOMMENDS 3 BACKFILL METHODS;
<br />STONESHOOTER LOCATED OFF THE CHAMBER BED.
<br />■ BACKFILL AS ROWS ARE BUILT USING AN EXCAVATOR ON THE FOUNDATION STONE OR SUBGRADE.
<br />+ BACKFILL FROM OUTSIDE THE EXCAVATION USING A LONG BOOM HOE OR EXCAVATOR.
<br />4. THE FOUNDATION STONE SHALL BE LEVELED AND COMPACTED PRIOR TO PLACING CHAMBERS.
<br />5. JOINTS BETWEEN CHAMBERS SHALL BE PROPERLY SEATED PRIOR TO PLACING STONE.
<br />6, MAINTAIN MINIMUM V (230 mm) SPACING BETWEEN THE CHAMBER ROWS_
<br />7. INLETAND OUTLET MANIFOLDS MUST BE INSERTED A MINIMUM OF mm) 12" 300 INTO CHAMBER END CAPS.
<br />(
<br />8. EMBEDMENTSTONE SURROUNDING CHAMBERS MUST BE A CLEAN, CRUSHED, ANGULAR STONE MEETING THE AASHTO M43 DESIGNATION OF #3
<br />OR #4.
<br />9. STONE SHALL BE BROUGHT UP EVENLY AROUND CHAMBERS SO AS NOT TO DISTORT THE CHAMBER SHAPE. STONE DEPTHS SHOULD NEVER
<br />DIFFER BY MORE THAN 12" (300 mm) BETWEEN ADJACENT CHAMBER ROWS,
<br />10. STONE MUST BE PLACED ON THE TOP CENTER OF THE CHAMBER TO ANCHOR THE CHAMBERS IN PLACE AND PRESERVE ROW SPACING.
<br />11. THE CONTRACTOR MUST REPORT ANY DISCREPANCIES WITH CHAMBER FOUNDATION MATERIAL BEARING CAPACITIES TO THE SITE DESIGN
<br />ENGINEER.
<br />12. ADS RECOMMENDS THE USE OF'TLEXSTORM CATCH IT" INSERTS DURING CONSTRUCTION FOR ALL INLETS TO PROTECT THE SUBSURFACE
<br />STORMWATER MANAGEMENT SYSTEM FROM CONSTRUCTION SITE RUNOFF.
<br />NOTES FOR CONSTRUCTION EQUIPMENT
<br />1. STORMTECH MC-4500 CHAMBERS SHALL BE INSTALLED IN ACCORDANCE WITH THE "STORMTECH MC-35001MC-4500 CONSTRUCTION GUIDE".
<br />2. THE USE OF EQUIPMENT OVER MC-4500 CHAMBERS IS LIMITED:
<br />• NO EQUIPMENT IS ALLOWED ON BARE CHAMBERS.
<br />• NO RUBBER TIRED LOADER, DUMP TRUCK, OR EXCAVATORS ARE ALLOWED UNTIL PROPER FILL DEPTHS ARE REACHED IN ACCORDANCE
<br />WITH THE "STORMTECH MC-35001MC-4500 CONSTRUCTION GUIDE".
<br />• WEIGHT LIMITS FOR CONSTRUCTION EQUIPMENT CAN BE FOUND IN THE "STORMTECH MC-35001MC-4500 CONSTRUCTION GUIDE"-
<br />3. FULL 36" (900 mm) OF STABILIZED COVER MATERIALS OVER THE CHAMBERS IS REQUIRED FOR DUMP TRUCK TRAVEL OR DUMPING.
<br />T USE OF A DOZER TO PUSH EMBEDMENT STONE BETWEEN THE ROWS OF CHAMBERS MAY CAUSE DAMAGE TO CHAMBERS AND IS NOT AN ACCEPTABLE
<br />BACKFILL METHOD. ANY CHAMBERS DAMAGED BY USING THE "DUMP AND PUSH" METHOD ARE NOT COVERED UNDER THE STORMTECH STANDARD
<br />WARRANTY.
