Do not allow coating to contact items to be embedded in concrete. Apply in compliance with manufacturer's instructions.

3.5

STRIPPING A. It shall be the Contractor's sole responsibility to remove the forms in such a manner that will assure complete safety of the structure. B. Formwork not supporting concrete, such as sides of beams, walls, columns, and similar parts of the work, may be removed after concrete has hardened sufficiently to maintain its integrity and not be damaged by form removal operation but not less than 24 hours of curing at not

less than 50 degrees Initiate and maintain curing and protection of concrete immediately after stripping of forms. C. Reduced stripping time for columns and walls, less than 12 feet in height will be considered when requested in writing. Provide adequate concrete strength curves, temperature data and curing procedures to substantiate adequacy of concrete age and conditions of requested stripping time. D. Do not remove formwork supporting members such as beams, slabs, and other structural elements until concrete has attained 75% of its 28-day compressive design strength but not sooner than seven (7) days. Determine compressive strength of in-place concrete by testing field-cured specimens representative of concrete location of members. Such field-cured specimens are in addition to specified testing requirements and are for the use of, and the responsibility of, the contractor and shall be at no additional cost. E. Reshore immediately after stripping slabs, beams and girders that support subsequent formwork. Keep reshores in place until the concrete has attained its 28-day compressive design strength and heavy construction loads have been removed, but not less than 14 days, unless otherwise noted on drawings.

CONCRETE PLACEMENT A. Preplacement Inspection: Before placing concrete, inspect and complete formwork installation, reinforcing steel, and items to be embedded or cast-in. Notify other crafts to permit installation of their work; cooperate with other trades in setting such work. Moisten wood forms immediately before placing concrete, where form coatings are not used. B. Coordinate the installation of joint materials and moisture barriers with placement of forms and reinforcing steel. C. General: Comply with ACI 301, ACI 304, ACI 308, ACI 318, and as herein specified. D. Jobsite Tempering: Place concrete within 1-1/2 hours after introduction of water to mix. Submit time stamped batching tickets upon delivery of concrete to job site. 1. Do not add water to ready-mix concrete unless the maximum design mix water content was not reached, in which case only the amount withheld can be added. Authorization of the addition of water can be done only by the Design Professional or the Special Inspector. The addition of water should be carried out only by the provider’s representative. 2. Concrete produced with high range water reducer may only be retempered with additional high range water reducer. E. Deposit concrete continuously or in layers of such thickness that no concrete will be placed on concrete which has hardened sufficiently to cause the formation of seams or planes of weakness. If a section cannot be placed continuously, provide construction joints as herein specified. Deposit concrete as nearly as practicable to its final location to avoid segregation. F. Placing Concrete in Forms: Deposit concrete in forms in horizontal layers not deeper than 24" and in a manner to avoid inclined construction joints. Where placement consists of several layers, place each layer while preceding layer is still plastic to avoid cold joints. G. Maximum height of concrete free fall is 4 feet. H. Concrete in columns and walls shall be at least four (4) hours old before horizontal members they support are cast. I.

Place vibrators to rapidly penetrate placed layer and at least 6" into preceding layer. Do not insert vibrators into lower layers of concrete that have begun to set. At each insertion limit duration of vibration to time necessary to consolidate concrete and complete embedment of reinforcement and other embedded items without causing segregation of mix.

K. Placing Concrete Slabs: Deposit and consolidate concrete slabs in a continuous operation, within limits of construction joints, until the placing of a panel or section is completed. 1. Consolidate concrete during placing operations so that concrete is thoroughly worked around reinforcement and other embedded items and into corners. 2. Bring slab surfaces to correct level with straight edge and strike off. Use bull floats or darbies to smooth surface, free of humps or hollows. Do not disturb slab surfaces prior to beginning finishing operations. 3. Maintain reinforcing in proper position during concrete placement operations. L. Cold Weather Placing: Protect concrete work from physical damage or reduced strength that could be caused by low temperatures, in compliance with ACI 306. M. Hot Weather Placing: 1.

Concrete Temperature Degrees Fahrenheit 95 90 85 80 75

Minimum Relative Humidity 70 60 50 40 30

The above Table is based upon a wind speed of 10 mph. For ambient wind speeds in excess of 10 mph, the Contractor shall follow the recommendations of Fig.2.1.5 of ACI 305R if the relationship of air temperature, wind velocity, relative humidity and concrete temperature indicate a rate of evaporation in excess of 0.2 pounds per sq.ft. per hour. In no case shall concrete have a temperature in excess of 95 d. F. be placed. 2. Cool ingredients before mixing to maintain concrete temperature at time of placement below 95 degrees F. Mixing water may be chilled, or chopped ice may be used to control temperature provided water equivalent of ice is calculated to total amount of mixing water. Use of liquid nitrogen to cool concrete is Contractor's option. 3. Fog spray forms, reinforcing steel and subgrade to maintain at ambient temperature before concrete is placed. 4. Use water-reducing retarding admixture (Type D) when ambient temperature exceeds 85 degrees or when other adverse placing conditions require. N. Construction Joints

SECTION 32 90 19 PLANTING: LONG TERM MAINTENANCE PART 1 GENERAL 1.1

SUMMARY A.

Museum Park is a public space owned and operated by the City of Miami, hereinafter referred to as “City”. Any and all contractors associated with this project are hereinafter referred to as “Contractor”.

B.

The landscape design objectives are to provide a variety of visually pleasing, accessible outdoor spaces for the public that reflect South Florida’s native ecology and provide the foundation for a diversity of uses and experiences. Twenty-two acres of park include spaces for formal and informal gatherings, exploration and discovery, peaceful relaxation and the excitement of active recreation. The emphasis is on native and drought tolerant species to reduce maintenance, but where simple, routine maintenance is required, the care and effort will bring a large return back to the city through this gift of nature and green-space to its residents.

C.

The maintenance levels have been classified as Schedule I and II. The Schedule I maintenance program has the highest level of maintenance requirements. The Schedule II maintenance program has moderate to low levels of maintenance. The scope-of-work for each Schedule of Maintenance is summarized in the table below:

Task Trash Pick-Up Hardscape Cleaning

Schedule I Daily Daily

Schedule II Daily Weekly

Irrigation System Checks and Repairs Mowing Edging and Trimming Shrub Pruning Mulching Weeding Tree Pruning, Hardwoods

Monthly

1 time every 2 months

42 cuts per year Monthly Twice Monthly Quarterly Twice Monthly 1 time every 2 to 3 years 3 times per year

N/A N/A Monthly Twice Annually Monthly 1 time every 3 to 5 years 2 times per year

Quarterly Monthly

3 times per year Quarterly

Tree Pruning, Palms Fertilization Pest Scouting and Treatment

D.

1.2

The specific areas which require Schedule I (highest level) of landscape maintenance include the Promenade, Garden Rooms, and all turf areas. The areas which require Schedule II (moderate level) of landscape maintenance include the baywalk areas and south parking lot.
