LANDSCAPES – SECTION 02312
Since landscape grading is aesthetic by nature, the work is subject to continual monitoring and modification during backfilling. Unless there is a separate bid item for landscaping, this work is considered incidental to other items of work, all costs are included in other bid items, and no separate measurements for payment are made. 02312: GRADING FOR LANDSCAPES
Pre-Inspection Existing features, such as trees, shrubs, curbs and fences, are protected. Line, levels, contours, and datum have been identified prior to beginning work.
Field Inspection Grading allows proper drainage. Embankment and backfill soils comply with specifications of Section 02056. Topsoil quality, sampling, submittals, and placement comply with all specifications of Section 02912. Refer to subsection (c) below. Vegetation is not damaged during construction.

Contractor has adjusted all heads and valve boxes to be plumb and flush with finished grade. Contractor has notified the Engineer 24 hours in advance of pressure testing the mainline. All pipes are bedded a minimum of 2". All connections have been properly tested for leaks before backfilling. Backfill material is comprised of native, excavated material, passed through a ½" sieve, and properly compacted. Repairs to the irrigation system or surrounding vegetation are done at no additional cost to the Department. Final inspection of the functional system with the Region Landscape Architect is scheduled through the Engineer. Any open trenches in the clear zone are barricaded overnight.

GROUNDCOVERS – SECTION 02932
During site inspection, ensure the placement area has been properly prepared to receive the plants. This includes verifying proper grade according to the plans, work has been completed in that area, the irrigation system is fully operational, and topsoil has been properly placed. Then the location of each plant should be staked or delineated according to the plans and approved by the Engineer. Of course, all plants should be healthy and maintained before and after planting. Plants should be free from disfiguring knots, sun-scald, frost cracks, abrasions of the bark, cracks in burlap-covered roots, and all forms of infestation and disease. Note problems in the daily log. After planting, ensure the plants are watered sufficiently within 24 hours of placement and maintained until final inspection. After inspection, all tags attached to plants should be removed, and the site should be tidy. 02932: TREES, SHRUBS AND GROUNDCOVERS

9.3 INCIDENTAL CONSTRUCTION
A) MOBILIZATION – SECTION 01285 Mobilization consists of the operations performed in preparation of work, such as equipment placement at the project site. While there are no specific inspection requirements for this item, the inspector should maintain an accurate record of the delivery and removal of equipment, materials, and workforce throughout the duration of the project in the inspector’s daily report. See the inspection preparation section of this manual for more information.
B) PUBLIC INFORMATION SERVICES – SECTION 01315 The contractor’s public information coordinator (PIC) is responsible for notifying the public of construction activities and maintaining contact with the Engineer and Regional Public Involvement Manager throughout the duration of the project. The PIC may not be the project superintendent. The PIC’s public information services duties include maintaining a local public information office, established working hours and days, and telephone availability. Inspectors should ensure the PIC has developed a database of stakeholder name and contact information and a method of distributing information. The PIC should also organize, participate in, and document public meetings involving the project when requested by the Engineer. Responding to public inquiries regarding project activities and schedules is also an important part of the PIC’s responsibilities. Payments for public information services are based on a percentage of project completion and paid in partial payments as the contractor provides the services. Weekly deductions in payments are imposed for failure to provide the services. While the Engineer and Regional Public Involvement Manager monitor and evaluate the PIC, inspectors should also note public involvement services in daily logs. 01315: PUBLIC INFORMATION SERVICES Database of stakeholder and contact information has been created. Public involvement services are effectively notifying the public.

CHAPTER 9
C) SURVEY – SECTION 01721 Survey inspection includes requirements for contractor verification of project control used to design the project before any staking is performed. Additionally, survey includes all work necessary to properly control layout and construction of project features and the generation of accurate “as-constructed” or “as-built” drawings. It is recommended that the field office maintain a clean copy of the contract documents regularly marked up with as-built information that can be used to verify the contractor’s as-constructed drawings. Prior to beginning work, the contractor should notify the Engineer of the accurateness of all specified tolerances of the horizontal and vertical controls. The correction of any survey errors discovered during construction is the contractor’s responsibility, as are the costs of overruns resulting from those errors. As surveying begins, ensure all work is done in accordance with the plans and specifications. Verify the placement of all reference stakes that identify stationing, and ensure that they are no more than 100 feet apart. Ensure that all survey and staking meets tolerances prior to beginning work, and the lay- out of the construction site is staked according to plans and specifications. The Contractor is responsible for costs incurred to relocate any utility more than once due to inaccurate or incomplete staking. All staking necessary for work must be maintained through- out the entire duration of construction, until acceptance of completion by the Engineer. After accepted project completion, all staking materials must be removed and disposed. If a “directed survey” is requested by the Engineer for any extra survey work or changes, the contractor should obtain prior written authorization from the Department before proceeding with that work. If the contract does not include a separate pay item for survey, the survey costs will be included in each item of work that requires it. No particular measurements for payment are required of inspectors beyond manpower and equipment notations in daily notes. 01721: SURVEY
Pre-Inspection Verification of project control received before any staking. Verify As-Constructed and As-built Drawings.
Field Inspection Survey and staking meets tolerances. Layout of construction site is staked according to plans and specifications. Verify reference stakes identifying stationing as per specification. Authorization and completion of a directed survey, if applicable.
