will prevent segregation or loss of ingredients. The stream of concrete shall not be allowed to separate by permitting it to fall freely over rods, spacers or other embedded materials.

B. Unless otherwise called out in these Specifications or shown on the Drawings, the placement lift depth of concrete in walls shall be limited to two (2) feet or less to minimize surface defects such as air voids that can form on concrete surfaces. Lift depths shall be limited to one (1) foot if, in the opinion of Owner’s Representative, the quality of the finish is unacceptable at the two- (2- ) foot lift depth.

C. Concrete shall be placed so as to avoid segregation of the materials and the displacement of the reinforcement.

D. Concrete shall not be dropped more than five (5) feet unless confined by closed chutes or pipes. Care shall be taken to fill each part of the form by depositing the concrete as near final position as possible. The coarse aggregate shall be worked back from the forms and worked around the reinforcement without displacing the bars. After initial set of the concrete, the forms shall not be jarred and strain shall not be placed on the ends of projecting reinforcement.

E. Where steep slopes are required, the chutes shall be equipped with baffle boards or be in short lengths that reverse the direction of movement.

F. Concrete shall not be pumped through aluminum alloy pipe.

G. All chutes, troughs, and pipes shall be kept clean and free from coatings of hardened concrete.

Concrete vibrators for consolidating concrete shall be two and one-half inch (2-1/2") diameter “high cycle” vibrators with a frequency under load of eight thousand (8,000) to ten thousand four hundred (10,400) vibrations per minute (vpm). Concrete vibrators of lesser capacity are unacceptable for use in any part of the construction. Contractor shall have at least one standby concrete vibrator ready for use for every two (2) concrete vibrators in use during a concrete placement.

B. All concrete shall be thoroughly consolidated with internal vibrators as recommended in ACI 309 immediately after deposition. The concrete shall be thoroughly worked around the reinforcing steel, around embedded items and into corners of forms. Vibration shall be supplemented by spading, rodding, or forking to eliminate all honeycomb and voids around embedded items.

C. The vibrator shall be inserted vertically, allowing it to penetrate rapidly to the bottom of the lift and at least six (6) inches into the previous lift. The vibrator shall be held at the bottom of lift for five to fifteen (5 - 15) seconds. The vibrator shall be pulled up at a rate of about three (3) inches per second.

General Vang Pao Park Section 030000
February 2026 Concrete

030000-11
D. The vibrator shall be inserted so that the fields of action overlap. The field of action is approximately eight (8) times the vibrator’s head diameter. Thus for a two and one-half (2-1/2) inch diameter vibrator, the spacing of each insertion shall be approximately twenty (20) inches.

E. Vibration shall be stopped when the concrete surface takes a sheen and large air bubbles no longer escape.

F. Do not use a vibrator to move concrete horizontally.

3.4 OPENINGS AND INSERTS
A. Pipe sleeves, inserts for pipe connections, anchors, and forms for pipe holes shall be accurately placed and securely fastened to the forms in such a manner that the placing of concrete shall not alter their alignment or location.

1.3 DESCRIPTION - DEFINTIONS
A. “System Location” is the exact location of the system installation. The geographic coordinates are used to determine anticipated Solar Insolation.

B. “Solar Insolation” is the amount of solar radiation available at the geographic location. Properly designed systems will use the lowest minimum monthly average (typically December in the Northern Hemisphere) when calculating the Array size.

C. “Photovoltaic or PV” a method of converting solar radiation energy into direct current electricity.

D. “Lighting Profile” is the way in which the LED Luminaire is powered throughout the night accumulating to give the total energy used by the system. This is sometimes referred to as the dimming profile as luminaries can be set to dim the light output for a portion of the night to reduce the total energy load of the system.

E. “Photovoltaic Panel Tilt Angle” – The angle relative to horizontal, to which the PV panel is tilted while pointing towards the equator. Tilt angle influences the amount of energy that can be collected at a given location at specific time of year.

F. “LED Luminaire” is a complete lighting fixture housing solid state lights, lens optics, and heat sink.

G. “Luminaire Wattage” is the energy used by the luminaire to produce light. Used in the calculation of the system load.

H. “Light Distribution” are general IES classification for different types of optics used to project the light emitted from the LED. Each type projects the light in different ways which allows designers to optimize the light uniformity for a given area.

I. “Light uniformity” is how well the light from multiple luminaires is distributed over a given

J. “IES LM 79” – is a standardized test which measures total luminous flux, luminous intensity distribution, electrical power, efficacy (lumens per watt delivered), and color characteristics (chromaticity, CCT, and CRI) of the complete luminaire. This test must be done by an accredited independent laboratory.

K. “Color Temperature” – measured in Kelvin, denotes how warm or cool the color produced by the luminaire is. Typically, 3000k-4000K.

L. “Batteries” – how the energy produced by the PV array is stored for nighttime use to power the luminaire load.

M. “SOC” is level of charge of an electric battery relative to its capacity.

N. “Anti-Blackout” – Load management based on battery state of charge.

D. Do not excavate within drip line of remaining trees, unless otherwise indicated.

E. Where excavation for new construction is required within drip line of trees, hand clear and excavate to minimize damage to root systems. Use narrow-tine spading forks, comb soil to expose roots, and cleanly cut roots as close to excavation edge as possible.

1. Cover exposed roots with burlap and water regularly.

2. Temporarily support and protect roots from damage until they are permanently relocated and covered with soil.

3. Coat cut faces of roots more than 1-1/2-inches in diameter with an emulsified asphalt or other approved coating formulated for use on damaged plant tissues.

4. Cover exposed roots with wet burlap to prevent roots from drying out. Backfill with soil as soon as possible.

F. Also see Tree Protection requirements outlined on Construction Drawings.

RESTORATION
A. Restore damaged improvements to their original condition, as acceptable to the Owner.

B. Repair or replace trees and vegetation indicated to remain that are damaged by construction operations, as directed by the Owner.

1. Employ a qualified, licensed arborist, to submit details of proposed repairs and to repair damage to trees and shrubs.

2. Replace trees that cannot be repaired and restored to full-growth status, as determined by the Owner.

3.2 CLEARING AND GRUBBING
A. Install tree protective fencing around trees designated to be saved, prior to the start of demolition work. See Civil and Landscape Plans and Specifications. Install fencing as far from the trunk as possible to allow for construction of proposed improvements. Maintain fencing throughout duration of construction.

B. Use only hand methods for grubbing within drip line of remaining trees.

C. Do not remove trees, shrubs, and other vegetation indicated to remain or to be relocated.

D. The area above the natural ground surface shall be cleared of all vegetation such as trees not designated to be saved, roots, brush, grass, weeds, and all other objectionable material including buildings (footings, slabs, etc.), asphalt, concrete, curbs, mulch, headerboard, ramps, stairs, utility piping (including appurtenances), bike racks, fences/gates, site furniture, and similar materials, within the limits of construction.

E. All concrete and asphalt pavements and other existing improvements within the areas to be developed should be removed during site demolition. At the Contractor’s option, salvaged class 2 aggregate base material may be stockpiled for reuse.

F. Existing building foundations should be entirely removed below final subgrade in the building pad areas, and to a depth of at least three feet in areas outside the building footprints. The excavations beneath the planned building area should be backfilled with engineered fill. See also Section 312000.

G. The natural ground surface within the entire site, except within the tree protection zones, shall be grubbed to a depth necessary to remove all stumps, buried logs, roots over 2-inches in diameter, and all other unsuitable material. Stumps shall be removed to a depth of at least 24” below original grade.

H. Existing utilities designated to be removed that do not conflict with proposed improvements may be

abandoned in place. If they are abandoned in place, the utility shall be slurried and capped. Any portions of these utilities that conflict with the new improvements shall be removed.

I. All unsuitable material shall be removed from the construction area and disposed of properly. Comply with hazardous material abatement regulations that may apply.

3.3 DEMOLITION SEQUENCING
A. Permanent and/or temporary facilities may need to be installed prior to demolition to limit utility outages. Any planned and or necessary interruption of existing utilities shall be coordinated with the Construction Manager. A minimum of one week’s notice shall be provided before any such interruption.

3.4 STRIPPING
A. The upper soils containing grass, small roots, and other vegetation, to a depth of 4+/- inches, shall be stripped from and removed from the site. Deeper stripping may be required in localized areas to remove roots or other concentrations of organic material.

B. Dust control shall be performed by the contractor during all phases of the construction. Payment for the dust control work involved shall be considered included in the items of work and no additional allowance will be made therefor.

C. The Geotechnical Engineer will observe the clearing and stripping operations and recommend the maximum depth of stripping required and any additional excavation necessary due to contamination of materials or concentrations of vegetation.

D. All suitable stripped material in excess of those needed to backfill landscape and/or planter areas shall be removed from the project site and disposed of properly.

3.5 CLEARED MATERIAL
A. The objectionable cleared material including buildings (footings, slabs, etc.), curbs, mulch, headerboard, ramps, utility piping (including appurtenances), bike racks, fences/gates, site furniture, etc., shall be removed from the project site and disposed of properly.

3.6 STRIPPED MATERIAL
A. Excess and objectionable stripped material including asphalt and concrete pavements, grass/vegetation, etc. shall be removed from the project site and disposed of properly. Contractor is encouraged to recycle the existing aggregate base materials for use in hardscape areas only (nonbuilding).

3.7 EROSION AND SEDIMENT CONTROL
A. Install and maintain erosion control devices/measures, including, but not limited to drainage inlet protection, fiber rolls, silt fence, etc., until such time as all vegetative and hard surface improvements within their individual tributary areas are completed. Provide periodic maintenance of all such devices, and following completion of said improvements, remove and dispose of erosion control devices and repair surfaces to match final specified surface finishes.

B. Any areas where ground has been disturbed, and where final landscaping has not been installed, will require the installation and maintenance of erosion control devices by the Contractor, as generally noted in the Erosion Control Notes on the plans.

C. Additionally, the Contractor shall implement and adhere to the requirements of the Storm Water Pollution Prevention Plan (SWPPP), including, but not limited to, rain event inspections, storm water discharge sampling and analysis, vehicle/equipment maintenance, and cleaning, etc..
