FOR

THE IRVINE COMPANY


A. INTRODUCTION

It is the intent of this Irrigation Design Guidelines to provide the irrigation designer with the

required design information to design a complete irrigation system for all commercial

landscape properties designated as a part of The Irvine Company’s Investment Properties

Group portfolio, including but not limited to streetscapes, commercial properties, resort

properties and office properties while recognizing the need to use water as efficiently as

possible.

The guidelines and specifications contained in this section are intended to be used during the

design and construction of all irrigation systems owned, operated and maintained by the

Investment Properties Group or their designated representative.

All working drawing plans prepared for the construction of irrigation system shall be submitted

in a review process for conformance to the guidelines and materials specifications.

For ease of use by the designer, the irrigation design guidelines have been broken down into

both graphical and text document. Graphical information has been provided to aid each

irrigation designer in designing the irrigation system for any Investment Properties Group

property. When graphical information is not provided, the irrigation design shall use the

irrigation design criteria outlined in the text document for preparation of irrigation plans.

Prototype irrigation system designs are included for the primary street landscape setbacks in

Irvine Spectrum. Prototype irrigation designs are also included for the secondary streets street

landscape setbacks in Irvine Spectrum. Refer to Section 2 of this document for additional

information.

1. Graphic documents shall consist of the following:

a. Irrigation sprinkler legend and irrigation equipment legend.

b. Irrigation construction details.

c. Typical irrigation layouts of known Irvine Spectrum streetscape master association

common area conditions.

2. The text documents included herein provide back up and design information for the

graphic documents. Also included as a part of the design guideline portion of the irrigation

design concept plan are:

a. Final design assumptions

b. Statement of site conditions

c. Water use requirements

d. Water conserving design strategies

e. Approved irrigation materials and equipment list and irrigation design criteria.


Page 2

B. GOAL:

It is the intent of these guidelines to provide the consistency required to help ensure that

irrigation systems installed for the Investment Properties Group portfolio can be operated and

maintained with the same standard of water conservation. This can be achieved through

innovative irrigation design, construction and application. In addition, maintenance of irrigation

systems installed in accordance with these guidelines will prove to be easily performed, given

the general uniformity of components used throughout the Investment Properties Group

portfolio.

C. IRRIGATION DESIGN STANDARDS:

All the Investment Properties Group portfolio of on-site and off-site irrigation systems operated

and maintained by The Irvine Company shall be designed in accordance with these

guidelines. Under these guidelines where manufacturer’s names and catalog numbers are

given, it should be noted that only these manufacturer’s names and catalog numbers must be

used for the construction of all irrigation systems. The Irvine Company or their designated

representative shall have the sole right to accept or reject any product or material as an equal.

For on-site lots not owned, operated or maintained by The Irvine Company, the approved

materials and equipment list may be used as a guideline to the types of materials, which shall

be installed. Use of this list for on-site lots not owned, operated or maintained by The Irvine

Company is not mandatory and is not intended to be all-inclusive. Items, which provide the

general type of performance as items listed may be installed, as long as they are similar in

quality of construction and performance.

Any areas, which will be maintained by the City of Irvine, such as arterial street median

islands, etc., shall be designed and installed in conformance with the City of Irvine Standard

Plans.

All irrigation systems shall be designed utilizing irrigation materials conforming to the use of

recycled water and approved by the Irvine Ranch Water District (IRWD).

D. STATEMENT OF SITE CONDITIONS

1. PROPOSED WATER SOURCE AND DEMANDS:

a. Irrigation Water Source:

Where available, irrigation water shall be supplied from the Irvine Ranch Water

District’s off-site recycled water system. Irrigation water meters will be required to

accommodate anticipated irrigation water needs for both on-site and off-site landscape

area irrigation systems. Locations of irrigation water meters, if not already provided as

a part of the civil engineering water improvement plans, shall be determined by the


Page 3

irrigation designer and coordinated with the engineer of record for the project.

Backflow preventers will not be required for irrigation systems carrying reclaimed

irrigation water. However a master valve/strainer assembly will be required at each

point of connection. In general, irrigation systems with water pressures greater that 80

PSI shall require pressure reducing type master valves. The need for a pressure

reducing master valve shall be determined by the irrigation design parameters as

determined by the irrigation designer. Include the irrigation system design pressure

and the pressure setting for the pressure reducing master valve on the drawings.

b. Watering Time and Peak Irrigation Demands:

Based on historic evapo-transpiration rate, the peak water requirement for irrigated

landscaped areas is anticipated to be approximately 1.5 inches of water per week

during the hot summer months. The irrigation system will be designed to apply this

weekly requirement in a (6) six-day period, with a maximum watering time of (8) eight

hours per day. This will allow irrigation cycles to be completed during the late night

hours when evaporation, site outdoor activities, vehicular traffic, pedestrian traffic and

blowing winds will be at a minimum. Unless otherwise approved by The Irvine

Company’s authorized design representative the water window shall be from 10:00pm

to 6:00am. Drip irrigation system shall be allowed to operate out side of the 10:00pm

to 6:00am water window.

c. As a part of the overall irrigation plan and as a part of these design guidelines,

information regarding irrigation point of connection sizes, mainline stub-out sizes and

peak flow demands in gallons per minute (GPM) plus additional preliminary irrigation

system statistics shall be determined by the irrigation designer and shall be provided

as a part of the irrigation design and shall be shown on the irrigation drawings. The

irrigation design shall not exceed any of the proposed design parameters without

written consent from The Irvine Company’s authorized design representative.

d. The peak irrigation demand shall be estimated by the irrigation designer using the

anticipated site design parameters. Changes in the site design parameters may affect

the estimated peak irrigation demand and recalculation of peak irrigation demands

may be required.

2. HISTORICAL EVAPO-TRANSPIRATION RATES:

a. Evapo-transpiration (ET) is the amount of water that evaporates from the soil and

transpires from the plants. Reference evapo-transpiration (ETo) is a standard

measurement based on a large field of four - to seven - inch tall, cool season grass

that is well watered. The historical twenty year high (normal) ET o as computed by

CIMIS Water Station #75 in El Toro, California is shown as follows:


Page 4

MONTH ETo MONTH ETo

JANUARY 2.2” JULY 6.2"

FEBRUARY 2.7" AUGUST 6.1"

MARCH 3.7" SEPTEMBER 4.7"

APRIL 4.5" OCTOBER 3.7"

MAY 4.6" NOVEMBER 2.5"

JUNE 5.4" DECEMBER 2.0"

Total "Historical" Year ETo average is 48.3”

b. This information shall be used by the irrigation designer to determine irrigation point of

connection sizes, mainline stub-out sizes and peak flow demands that may be required

prior to completion of the irrigation system design. Flow demands shall be shown in

gallons per minute (GPM).

E. WATER REQUIREMENTS

1. GENERAL:

a. The numerous factors which influence the water requirements for landscaping can be

grouped into three (3) categories.

1) Environmental Conditions - soil characteristics, natural precipitation, sun

exposure, slope aspect, wind, etc.

2) Planting Design - selection of species, grouping and placement.

3) Irrigation Systems – sprinkler type, precipitation rate, hydrozones, irrigation

scheduling, temporary system vs. permanent system, etc.

b. Environmental conditions are for the most part a given although some modification is

possible, primarily with soils. Planting design and irrigation system design are the two

areas where the greatest impact on water conservation can be made. Both plant

selection and irrigation design, are based on the given environmental conditions for the

site along with the added objective to create aesthetic beauty.

2. LANDSCAPE IRRIGATION ZONES:

a. Management and conservation of water used for irrigation of landscaped areas will be

realized through the division of all landscaped areas into distinct IRRIGATION ZONES.

The purpose is to maximize the efficient use of irrigation water by allocating more

water to areas where it will have the greatest impact--i.e., in the immediate vicinity of

high and medium high water use landscape areas such as turf areas --and less water


Page 5

to areas with medium water use landscapes such as shrub areas and low water use

landscapes such as slopes with drought tolerant plant materials.

b. The water requirement of each zone is determined to a large extent by the selection of

plant species used in each zone. Plants having similar water requirements will be

grouped together in the same zone-i.e., low water users in one zone, moderate water

users in another, etc. Each zone will be irrigated separately and with the most

appropriate type of irrigation system (low precipitation spray, standard spray, rotors,

sub-surface drip, etc.). In this way, the frequency and amount of water being applied

through irrigation can be carefully controlled so as to avoid needless over-watering that

results when plants that have both high and low water requirements are mixed

together. Following is a description and plant factors for some landscape irrigation

zones:

June .88 0.5 0.3 December .60 0.5 0.3

The final plant palette selection will determine the final plant factor. Changes in the

plant palette can cause adjustments to the actual water consumption of the landscape.

F. IRRIGATION SCHEDULING

All irrigation scheduling shall be accomplished through the WeatherTRAK ETPRO2S-C-

SWM Smart Water Manager Series irrigation controller. The irrigation designer shall provide

all scheduling parameters and programming parameters as a part of the irrigation

construction document package. Construction documents shall instruct the Contractor to

provide the required set-up parameters for the WeatherTRAK ETPRO2S-C-SWM Smart

Water Manager Series irrigation controller. Set-Up worksheet for activation of the

WeatherTRAK ET ETPRO2S-C-SWM Smart Water Manager Series irrigation controller

shall be prepared by the Contractor. Irrigation scheduling parameters and programming

parameters shall be set for established plant materials based on the landscape and

irrigation construction documents. Irrigation scheduling parameters and programming

parameters shall be provided for all of the various landscape, environmental and irrigation

G. WATER CONSERVATION METHODS FOR IRRIGATION SYSTEMS

1. GENERAL:

a. State-of-the-art, weather based automatically controlled irrigation systems will be

utilized and designed into all of the Investment Properties Group landscaped areas.

Flow sensors and master valves shall also be provided to ensure water is applied

only when needed.

b. Irrigation systems shall be designed to include, but not be limited to the following:

1) Weather based irrigation controller with built in scheduling engine.

2) Connection to Internet Management services including daily ET updates.

3) Stainless Steel controller enclosures for mounting controllers including universal

radio remote ready connector.

4) Electric remote control valves.

5) Medium rotor heads, small spray heads, drip emitter and bubbler type heads.

6) PVC mainline and lateral line piping.

7) Gate valves.

8) Pressure reducing valve and Strainer assemblies for recycled water.

9) Backflow preventers for irrigation systems carrying potable water.

10) Low head drainage check valves for rotor heads and seal-a-matic feature on

pop-up type spray heads.

2. WATER CONSERVING IRRIGATION DESIGN APPROACH AND STRATEGIES:

a. Irrigation of the landscape should be divided into distinct zones. Irrigation zones

should be determined on the basis of types of plant material, climatic exposures, soil

type, and terrain. Specifically, irrigation zones should be designed according to the

following criteria:

1) Plant materials shall be separated into irrigation zones according to whether they

are turf, groundcover, shrubs, or drought tolerant plantings, etc.


Page 8

2) North and East exposures shall be separated from South and West exposures.

3) Areas with pronounced soil differences shall be separated from one another.

4) In general, high points shall be separated from low points (and drainage swales)

in landscape areas.

5) Sloped areas shall be separated from general landscape areas. (Slopes are

considered to be landforms with grades steeper than 3:1).

6) Top, toe and center of slope shall be considered separately.

7) Equal contours along slopes shall be grouped together, when possible.

8) In master association common areas, electric control valve systems shall not

extend beyond proposed lot lines. This will allow on-site developers to work and

construct within the confines of their property without disturbing the master

association common landscaped setback irrigation systems located on adjacent

properties.

b. The irrigation system shall be designed to prevent overspray or discharge onto non-

landscape areas.

c. The irrigation system shall be designed to meet the peak moisture demand of all

plant materials used within the design area. The irrigation cycle or cycles must be

completed within a given time period, during nighttime hours, when evaporation,

blowing winds and outdoor activities will be at a minimum.

d. As much as possible, irrigation water shall be applied at a rate, which does not

exceed the infiltration rate of the soil, and/or the system will be programmed to

prevent ponding and/or runoff.

e. The irrigation system shall be designed to minimize accidental damage and to

maximize pedestrian safety. In this way, water lost through broken sprinkler heads

and risers may be avoided.

f. Shrub sprinklers adjacent to roadways, pathways and sidewalks and in other guest

areas shall be pop-up type. Pop-up height will be 6" or 12" as may be required to

avoid interference from nearby plant material. Use 6” pop-up sprinklers with flat or

low angle nozzles to spray under shrub type plant materials where the sprinkler

spray pattern will be distorted by the shrub and where the height of the plant will be

maintained at a height of more that 12”. Use 12” pop-up sprinklers for ground

covers or other types of plant materials where the sprinkler spray pattern will not be

distorted by the plant material. The type of sprinkler required shall be determined by

the irrigation designer.

g. Due to site environmental conditions, slope conditions and unpredictable wind

patterns, especially during daytime hours during the plant establishment period, it


Page 9

will be necessary to establish sprinkler spacings. These spacings are considered

standard or normal in the industry. Maximum spacing of sprinklers will be as follows:

1) Short-range sprinklers with a spray diameter of 5 to 30 feet: spacing shall not

exceed 50% of diameter.

2) Intermediate-range sprinklers with a spray diameter of 31 to 80 feet: spacing

shall not exceed 50% of diameter.

h. Sprinklers controlled by any one electric control valve shall have compatible

precipitation rates. The difference between high and low precipitation rates within

the same section shall not exceed 20%.

i. Anti-drain valves will be utilized to prevent low head drainage and loss of irrigation

water after system has been shut off.

j. The use of sub-surface or on-surface pressure compensating continuous self-

cleaning dripperline shall be considered as a design alternative to a conventional

irrigation system for curved or angular narrow planting areas, high traffic areas, high

liability areas, areas subject to vandalism and in high wind areas. Such areas could

include but should not be limited to parking lot planting islands, at-grade windows,

etc.

k. The designer shall note on drawings the following: “When vertical obstructions (props, street lights, trees, etc.) Interfere with the spray pattern of the sprinkler heads so as to prevent proper coverage, the irrigation contractor shall field adjust the sprinkler system by installing a quarter circle or half circle sprinkler head on each side of the obstruction so as to provide proper coverage. All adjustments shall be made at no additional cost to the owner. (Typical)”

I. IRRIGATION SYSTEM DESIGN PARAMETERS, ASSUMPTIONS & REQUIREMENTS

1. Per current Irvine Ranch Water District (IRWD) standards and the Investment

Properties Group requirements, a maximum irrigation water window of eight (8)

hours has been established for all landscape projects.

2. Irrigation design criteria and irrigation flow requirements shall be based on a

maximum of six (6) irrigation days per week.

3. In some cases, the landscape setback areas will be constructed prior to the

installation of the lot where the landscape setback areas point of connection and

automatic sprinkler controller will be constructed. In such cases, the landscape

setback area shall be temporarily connected to the on-site irrigation system. When

the landscape setback area automatic controller and irrigation water service

becomes available, the landscape setback areas that are connected to the on-site

irrigation system shall be disconnected from the on-site irrigation system and

reconnected to the landscape setback irrigation water service and control system.

4. Locations of roadway crossings, water meters and electrical services for automatic

controllers shall be coordinated by the irrigation consultant/designer with the

landscape architect, civil engineer and utility consultant and shall be noted on the

appropriate civil and utility drawings as well as the irrigation construction documents.

All automatic controllers shall be provided with 120-volt electrical service.

5. Irrigation equipment, materials, construction details, irrigation specifications and

typical design conditions shown elsewhere in this guideline shall be used for design

and construction all irrigation systems. NO OTHER EQUIPMENT, MATERIALS,

CONSTRUCTION DETAILS, IRRIGATION SPECIFICATIONS OR DESIGN

CONDITIONS SHALL BE USED IN CONNECTION WITH THE DESIGN OR

CONSTRUCTION OF ALL LANDSCAPE IRRIGATION SYSTEM UNLESS

SPECIFICALLY APPROVED IN WRITING BY THE INVESTMENT PROPERTIES

GROUP’S AUTHORIZED REPRESENTATIVE.

6. Irrigation sleeving and conduits will be required and will need to be considered

prior to construction of any roadway, driveway or paving that occurs prior to the

construction of the irrigation system and shall be shown on the irrigation

construction documents. These sleeves and conduits shall also be shown on

engineering drawings when appropriate. As design development of each project


Page 18

progresses, the need for irrigation sleeves and conduits should be addressed by

the irrigation designer for construction consideration.

7. Within those on-site developments where the master association common area

irrigation system construction has been completed, it will be the responsibility of the

on-site irrigation designer to ensure that its irrigation design includes a procedure for

modification of the existing irrigation system that will be disturbed due to the

installation of new on-site driveways or entry ways. All modifications shall reflect the

intent of these irrigation design guidelines.

Note: The irrigation consultant/designer shall verify if master association common

area irrigation construction documents have been completed. If so, refer to these

plans plus the engineer’s street improvement plans for locations of common area

irrigation systems including, irrigation water meters, mainline piping, control wiring

and communication cable between common area irrigation systems. Also review

locations of existing irrigation street crossover sleeving, which may have been

installed as a part of the street improvement plans.

J. PLAN SUBMITTAL AND APPROVAL

All working drawing plans prepared for the construction of irrigation systems for projects

owned, operated and maintained by the Investment Properties Group shall be submitted for

review and conformance to these irrigation guidelines and materials specifications. The

irrigation plans shall be submitted along with other project plans scheduled for submittal to the

Investment Properties Group for approval.

K. SUMMARY

These “Irrigation Design Guidelines for The Irvine Company Investment Properties Group”

incorporate the latest in water conservation technology and practices currently available to the

landscape and irrigation industry. By combining state-of-the-art computer technology and

advanced water conserving irrigation system designs, the Investment Properties Group

maintenance contractors and property managers will be able to meet the Investment

Properties Group’s goals to conserve water and maximize efficiency in the utilization of human

and energy resources through implementation of a total landscape water management

program.

The irrigation system shall be designed to maximize the efficient use of irrigation water by

allocating more water to those landscape areas of high impact and less water to landscape

areas of low impact.

The irrigation systems throughout The Irvine Company’s Investment Properties Group

portfolio shall utilize the latest in weather based irrigation control technology and water

conservation techniques including flow sensors that will help ensure that the correct amount of

irrigation water is applied to the appropriate landscape zone.

Begin dripper tubing layout 2” to 3” away from both hard surfaces; i.e., concrete sidewalks, curbs, asphalt, and/or undefined edges; i.e., shovel-cut headers. Mark tubing intervals on the ground with flags, paint, or some other markings that can be maintained throughout the installation.

2. Dripper tubing can be installed in one of the three (3) following methods:

a. Over-excavation: In small areas, where it technically feasible, over-excavate the entire area to a depth of 4” below finish grade. Plant all specimen trees and shrubs, 15 gallon size and larger, then place tubing at the row spacing interval indicated on the plans.

b. Pipe Pulling: In larger areas, where ground disruption is to be minimized, pneumatic tire, pipe pulling machinery shall be used. Potholes shall be used at the ends of each run for making connection to supply and exhaust headers of rigid PVC pipe or poly pipe.

c. Trenching: Hand or mechanically trench to the pipe depth indicated on the plans or in these specifications and backfill flush with finish grade. Avoid mechanically trenching within the dripline of existing trees. Hand-trench around existing tree roots when roots of 2” and larger are encountered. Remove all rock 1-1/2” and larger when excavating and remove from site. Do not backfill trenches with rock that will come in direct contact with tubing or rigid PVC piping.

3. Install underground piping horizontally and as level as possible to a minimum depth of 3” and maximum depth of 5” unless otherwise specified. Optimum pipe depth is 4”.

4. As much as possible, supply and exhaust headers shall be installed perpendicular to contours.

5. As much as possible, dripper tubing shall be installed parallel with contours.

6. Dripper tubing can be installed with the water outlets facing upward or downward. Place dripper outlets in such a manner as to form a triangular pattern between parallel tubing laterals. In irregular areas, some water outlets may end up too close to fix improvements and may have to be capped off with a dripper plug ring.

7. Connect dripper tubing to barbed fittings by pushing on and over both barbs until the tubing has seated against another piece of tubing or has butted against another portion of the barbed fitting. For water pressures in excess of the 45 psi, use stainless steel clamps as noted in paragraph 8, “Pipe Clamping” on all barbed fittings.

8. When design operating pressure exceeds 45 psi, stainless steel pipe clamps shall be used. Slip clamps over tubing before slipping tubing over insert barbed fitting. Place clamp between the first and second ridge of the barbed fittings and crimp the “ear” of the clamp tightly. Crimp the


IRVINE, CALIFORNIA


02810 - 29

“ear” twice to ensure proper seating.

9. Install a pressure regulator below grade, downstream, and in line with the remote control valve. Whenever possible, place the pressure regulator in the same valve box to allow for periodic inspection. Place the regulator with the arrow (molded into the side of the body) pointing in the direction of the flow of water. Provide straight piping on the outlet side of regulator for a dimension not less than three lengths of the overall body dimension.

10. Install the disc filter, horizontally level, below grade and before or after the remote control valve as indicated in the installation details. The position of the disc filter in the valve box shall be off-center to allow for removal of the disc element for periodic servicing. Refer to the installation details for the size of the valve box.

11. Install the air/vacuum relief valve below grade and at the highest elevation within each zone. Depending on the site conditions and tubing layout, more than one air/vacuum relief valve into a 1/2" x 3/4” SCH 40 PVC reduction bushing and thread this assembly into a 180° 2-way adapter tee with a 3/4” (MPT) outlet. Place the valve within a round valve box with a locking cover and a 1 cu. Ft., 3/4” gravel sump as noted on the details. Additional blank Techline tubing may be necessary when placing Techline dripper tubing on mounds or berms with more than a 3’ elevation difference. Blank Techline tubing shall be connected perpendicular to the dripper tubing with barbed tees from the lowest elevation of dripper tubing to the highest point of the mound berm where the air/vacuum relief valve is located. This air/vacuum relief lateral serves to collect and transport trapped air bubbles or relieve vacuum in lower elevation dripper tubing parallel to the dripper tubing located at the highest point in the system. Locate an air/vacuum relief lateral for each berm within the system.

12. Prior to backfilling and before connection of the line flushing valves, flush the entire system to remove any dirt or sediment that may have entered the system during the installation.

13. Install the line flushing valve horizontally level and below grade at the hydraulic termination point(s) in each system. Locate in a valve box with the dome-shape of the valve facing upward. Include a minimum of 1 cu. Ft. of 3/4” crushed rock in the bottom of the valve box per construction detail.

14. Prior to backfilling, open the remote control valve and operate each circuit to check for leakage around both barbed and threaded PVC fittings. Make necessary corrections to stop leaks.

15. Re-test those systems where leaks were corrected before commencing backfilling operations.

3.05 TEMPORARY REPAIRS

The Owner reserves the right to make temporary repairs as necessary to keep the irrigation system equipment in operating condition. The exercise of this right by the Owner shall not relieve the Contractor of his responsibilities under the terms of the guarantee as herein specified.

3.06 EXISTING TREES Where it is necessary to excavate adjacent to existing trees, the Contractor shall use all possible care to

avoid injury to trees and tree roots. Excavation in areas where two (2) inch and larger roots occur shall be done by hand. All roots two (2) inches and larger in diameter, except directly in the path of pipe or conduit, shall be tunneled under and shall be heavily wrapped with burlap to prevent scarring or excessive drying. Where a ditching machine is run close to trees having roots smaller than two (2) inches in diameter, the wall of the trench adjacent to the tree shall be hand trimmed, making clean cuts through. Roots one (1) inch and larger in diameter shall be painted with two coats of Tree Seal, or equal. Trenches adjacent to tree should be closed within twenty-four (24) hours; and where this is not possible, the side of the trench adjacent to the tree shall be kept shaded with burlap or canvas.

square inch and proven watertight prior to paving. 4. Sustain pressure in lines for not less than two (2) hours. If leaks develop, replace joints and

repeat test until entire system is proven watertight. 5. All hydrostatic tests shall be made only in the presence of the Owner's Authorized

Representative. No pipe shall be backfilled until it has been observed, tested, and approved in writing.

6. Furnish necessary force pump and all other test equipment. 7. When the irrigation system is completed, perform a coverage test in the presence of the

Owner's Authorized Representative to determine if the water coverage for planting areas is complete and adequate. The coverage test shall be accomplished using a contractor furnished radio remote receiver and transmitter to turn each control valve on to observe sprinkler coverage and then to turn the control valve off when coverage test of that system is complete. Furnish all materials and perform all work required to correct any inadequacies of coverage due to deviations from the Drawings, or where the system has been willfully installed as indicated on the Drawings when it is obviously inadequate, without bringing this to the attention of the Owner's Authorized Representative. This test shall be accomplished before any ground cover is planted.

8. Upon completion of each phase of work, the entire system shall be tested and adjusted to meet

site requirements. The contractor shall provide an irrigation water schedule for plant establishment as well as any subsequent schedule changes for review and approval by owner.
