1.13 Construction Observation, Inspection & Testing

1) All public construction associated with development may be inspected or periodically observed by a professional engineer licensed in the State of Oregon (or a qualified individual under his supervision) as required in the Developer City Agreement. City projects may be inspected by Director.

2) An engineer whose firm, or any member of the firm, has a corporate, partnership or any form of real property interest in the development for which the improvements are required cannot be designated engineer-of-record. The engineer-of-record's relationship to the project must be solely that of a professional nature.

3) These inspection and construction observation requirements are not applicable to individual sidewalk, driveway or service lateral permits for single residences. If the project scale is such that the retention of an independent engineer-of-record is not warranted, the Developer may request that the City provide these services. If the City agrees to provide these services, the Developer shall be responsible to reimburse the City for any costs incurred for these inspection and/or construction observation services.

1) Services provided by the City shall include:

a) Monitoring of work progress and performance testing as required;

b) The performance of administrative and coordination activities as required to support the processing and completion of the project;

c) The issuance of Stop Work Orders.

d) Operate all valves, including fire hydrants, on existing waterlines.

2) In addition, the City shall be notified a minimum of 72 business hours (3 business days) prior to the following tests and inspections so that a City representative may be present to witness the inspections or tests.

(1) Curb inspection;

(2) Subgrade testing or proof rolls;

(3) Base rock testing;

(4) AC pavement placement and testing;

(1) Mandrel testing of mainlines;

(2) Air testing of mainlines;

(3) Vacuum testing of manholes;

(1) Mandrel testing of flexible pipe storm drains;

(2) Video inspection of mainlines;

(1) Pressure tests;

(2) Disinfection.

1) The engineer of record must be registered to practice engineering in the State of Oregon. Material testing which is not performed by the engineer-of-record must be accomplished by a recognized testing firm or another registered engineer.

2) The following minimum activities are required of the developer's ,engineer-of record:

a) *Execute a form accepting responsibility (i.e. the Developer-City Construction Agreement);

b) *Attend preconstruction conference and ensure that approved construction drawings are distributed to contractor, subcontractors and utility companies.

c) Obtain and use a copy of City-approved construction drawings and specifications;

d) Coordinate to ensure that the City is notified 48 business hours (2 business days) before the start of construction or resumption of work after shutdowns, except for normal resumption of work following Sundays or holidays.

e) During construction immediately call to the City's attention all drawing changes, material changes, stop work orders or errors or omissions in the approved drawings or specifications. All changes shall be approved by the City prior to implementation.

f) *Maintain records which contain at least the following information and submit copies to the City on a weekly basis:

(1) Any Site Visits during the previous week

(a) Date and time of site visits

(b) Weather conditions, including temperature

(2) Statement of directions to change drawings, specifications, stop work, reject materials or other work quality actions;

(3) Public agency contacts or franchise utility contacts which result in drawing changes or other significant actions;

(4) Perceived problems and action taken;

(5) Final and staged inspections (notify & coordinate with City to allow City representative to attend during regular business hours);

(6) Records of all material, soil and compaction tests.

g) The engineer-of-record shall either; (1) provide all surveying services necessary to stake the project prior to and during construction and as necessary to prepare as-built drawings when the project is complete, or

(2) confirm that these surveying services are being provided separately (by the developer or by the contractor) under supervision of a licensed surveyor, all in conformance with City Standards.

h) Review and approve all pipe, aggregate, concrete, A.C. and other materials submittals to ensure their compliance with City Standards, and provide any submittal review comments to Public Works and/or the City Engineer;

i) *Approve all drawing or specification changes in writing and obtain City approval prior to the performance of the work;

j) Provide periodic construction observations of construction activities as required to ensure end products meet City specifications;

k) *Perform (or verify that they are performed) material, compaction and other tests required to ensure City specifications are met;

l) Periodically check that curb, storm drain work and pavement grades are in substantial conformance with approved drawings;

m) For pavement construction, perform the following stage construction observations and record the date that each is verified:

(1) Curbs are built to line and grade;

(2) Subgrade meets grade and compaction specifications;

(3) Base rock meets grade and compaction specifications;

(4) Leveling course meets grade and compaction specifications;

(5) Wearing course meets grade and compaction specifications.

n) For sanitary and storm drain construction, perform the following stage construction observations and record the date that each is verified:

(1) Sewers are installed to proper line and grade;

(2) Trenches are properly backfilled and compacted;

(3) Construction staking is adequate to ensure that the sewer is properly installed with respect to easement, right-of-way and property lines;

(4) Air testing and video inspections are performed according to standard procedures.

o) For grading, verify that the grading plan, as staked, will result in acceptable slopes along exterior property lines, proper onsite and offsite drainage, and erosion control.

p) File completed and accepted development agreement.

q) Submit final reproducible record drawings conforming to the requirements outlined herein.
