accessories.C. Where new concrete is to be bonded to previously placed concrete, prepare existing surface by cleaning and

applying bonding agent in according to bonding agent manufacturer's instructions.1. Use epoxy bonding system for bonding to damp surfaces, for structural load-bearing applications, and

where curing under humid conditions is required.2. Use latex bonding agent only for non-load-bearing applications.

D. Where new concrete is doweled to existing work, drill holes in existing concrete and set steel dowels inepoxy bonding system in accordance with manufacturer's instructions including special inspection.

E. Grout solidly between column plates and bearing surfaces, complying with manufacturer's instructions fornonshrink grout. Trowel grouted surfaces smooth, splaying neatly to 45 degrees.


F. Interior Slabs on Grade: Install vapor retarder under interior slabs on grade. Lap joints minimum 6 inches.Seal joints, seams and penetrations watertight with manufacturer's recommended products and followmanufacturer's written instructions.

indicated on the drawings. Do not use sand.2. Not required where small sections of existing slabs are being removed and replaced.

3.03 PLACING CONCRETEA. Place concrete in accordance with ACI 301 and ACI 318.B. Provide concrete placing equipment including pump if required.C. Notify Architect not less than 24 hours prior to commencement of placement operations, when reinforcing

bars are in place for each pour in advance of closing forms and concrete placement. No closing of forms andplacing of concrete will be allowed until Architect/Engineer has observed structural concrete reinforcing inplace in forms. Corrections shall be made at Contractors expense.

D. Ensure reinforcement, inserts, and embedded parts will not be disturbed during concrete placement.E. Place concrete continuously without construction (cold) joints wherever possible; where construction joints

are necessary, before next placement prepare joint surface by removing laitance and exposing the sand andsound surface mortar, by sandblasting or high-pressure water jetting.

3.04 SLAB JOINTINGA. Locate joints as indicated on the drawings.B. Anchor joint fillers and devices to prevent movement during concrete placement.C. Isolation Joints: Use preformed joint filler with removable top section for joint sealant, total height equal to

CONSTRUCTION SEQUENCING

1. INSTALL SILT FENCE AND/OR OR OTHER APPROPRIATE TEMPORARY EROSION CONTROL DEVICES TO PREVENT SEDIMENT FROM LEAVING ORENTERING THE PRACTICE DURING CONSTRUCTION.

2. ALL DOWN-GRADIENT PERIMETER SEDIMENT CONTROL BMP'S MUST BE IN PLACE BEFORE ANY UP GRADIENT LAND DISTURBING ACTIVITY BEGINS.

3. PERFORM CONTINUOUS INSPECTIONS OF EROSION CONTROL PRACTICES.

4. INSTALL UTILITIES (WATER, SANITARY SEWER, ELECTRIC, PHONE, FIBER OPTIC, ETC) PRIOR TO SETTING FINAL GRADE OF BIORETENTION DEVICE.

5. ROUGH GRADE THE SITE. IF BIORETENTION AREAS ARE BEING USED AS TEMPORARY SEDIMENT BASINS LEAVE A MINIMUM OF 3 FEET OF COVEROVER THE PRACTICE TO PROTECT THE UNDERLYING SOILS FROM CLOGGING.

6. PERFORM ALL OTHER SITE IMPROVEMENTS.

7. SEED AND MULCH ALL AREAS AFTER DISTURBANCE.

8. CONSTRUCT BIORETENTION DEVICE UPON STABILIZATION OF CONTRIBUTING DRAINAGE AREA.

9. IMPLEMENT TEMPORARY AND PERMANATE EROSION CONTROL PRACTICES.

10. PLANT AND MULCH BIORETENTION DEVICE.

11. REMOVE TEMPORARY EROSION CONTROL DEVICES AFTER THE CONTRIBUTING DRAINAGE AREA IS ADEQUATELY VEGETATED.

GENERAL NOTES

1. IN THE EVENT THAT SEDIMENT IS INTRODUCED INTO THE BMP DURING OR IMMEDIATELY FOLLOWING EXCAVATION, THIS MATERIAL SHALL BEREMOVED FROM THE PRACTICE PRIOR TO CONTINUING CONSTRUCTION.

2. GRADING OF BIORETENTION DEVICES SHALL BE ACCOMPLISHED USING LOW-COMPACTION EARTH-MOVING EQUIPMENT TO PREVENT COMPACTIONOF UNDERLYING SOILS.

3. ALL SUB MATERIALS BELOW THE SPECIFIED BIORETENTION DEPTH (ELEVATION) SHALL BE UNDISTURBED, UNLESS OTHERWISE NOTED.
