TASK 4: CONSTRUCTION ADMINISTRATION

Provide the following construction administration services.

• Arrange, prepare for, and attend one pre-construction meeting with the County, contractor

and appropriate stakeholders designated by the County Manager to discuss the Project

construction; develop a Project schedule; review permits, plans and specifications;

identify concerns and issues; and establish lines of communication and contact people.

• Consult with the County and contractor as reasonably required and necessary with regard

to construction of the Project, assist the County issue interpretations and clarifications

during construction, and prepare work change orders as directed by the County, if

necessary.

• Attend three meetings with County and designated stakeholders.

• Upon receiving written notice from the County that the Project is substantially complete,

conduct a one-time comprehensive review of the Project, develop a list of items needing

completion or correction, forward said list to the contractor and provide written

recommendations to County concerning the acceptability of work done and the use of the

Project

perform final site observations in conjunction with the County, and assist the County in

closing out construction contract.

• Prepare and submit to the County and agencies as required a Project Completion Report

including the required agency Final Certifications along with the weekly monitoring

reports and as-built surveys.

TASK 5: CONSTRUCTION SURVEYS AND OBSERVATIONS

Provide the following construction surveys and observations. • Make visits to the site at intervals appropriate to the various stages of construction as

deemed necessary in order to observe as an experienced and qualified design professional the progress and quality of the various aspects of contractor’s work. Based on information obtained during such visits and on such observations, endeavor to determine in general if such work is proceeding in accordance with the Contract Documents and keep the County informed of the progress of the work. Provide a weekly progress report to the County summarizing the construction completed to date. The purpose of the visits to the site will be to better carry out the duties and responsibilities assigned to and undertaken during the Construction Phase, and, in addition, by exercise of these efforts as an experienced and qualified design professional, to provide for the County a greater degree of confidence that the completed work of contractor will conform generally to the Contract Documents and that the integrity of the design concept as reflected in the Contract Documents has been implemented and preserved by the contractor. On the other hand, we shall not, during such visits or as a result of such observations of the contractor’s work in progress, supervise, direct or have control over the contractor’s work nor authority over or responsibility for the means, methods, techniques, sequences or procedures of construction selected by the contractor, for safety precautions and programs incident to the work of the contractor or for any failure of the contractor to comply with laws, rules, regulations, ordinances, codes or orders applicable to the contractor furnishing and performing their work. Accordingly, we can neither guarantee the performance of the construction contracts by the contractor nor assume responsibility for the contractor’s

failure to furnish and perform their work in accordance with the Contract Documents. During such visits and on the basis of such observations, disapprove of or reject the contractor’s work while it is in progress if it is believed that such work will not produce a completed Project that conforms generally to the Contract Documents or that it will preju-dice the integrity of the design concept of the Project as reflected in the Contract Documents. The budget includes 30 site visits over the anticipated 120 day Contract Window noting this window includes mobilization, demobilization, downtime for weather, etc… during which no construction observations shall be made.

• Utilizing the survey data provided by the County in accordance with state and federal

standards, prepare and submit to the County and contractor a plan view drawing of the

dredging along with a delineation of areas that do not meet the Contract Documents.

Determine the amounts owed to the contractor and recommend in writing payments to the

contractor(s) in such amounts. Such recommendations of payment will constitute a rep-

resentation to County, based on such observations and review, that the work has

progressed to the point indicated, and that, to the best of our knowledge, information and

belief, the quality of such work is generally in accordance with the Contract Documents

(subject to an evaluation of such work as a functioning whole prior to or upon Substantial

Completion, to the results of any subsequent tests called for in the Contract Documents

and to any other qualifications stated in the recommendation). By recommending any

payment, we will not thereby be deemed to have represented that exhaustive, continuous

or detailed reviews or examinations have been made to check the quality or quantity of

contractor work as it is furnished and performed beyond the responsibilities specifically

assigned in this Agreement and the Contract Documents. Our review of the contractor’s

work for the purposes of recommending payments will not impose on us the responsibility

to supervise, direct or control such work or for the means, methods, techniques,

sequences, or procedures of construction or safety precautions or programs incident

thereto or contractor compliance with laws, rules, regulations, ordinances, codes or orders

applicable to their furnishing and performing the work. It will also not impose

responsibility on us to make any examination to ascertain how or for what purposes the

contractor has used the moneys paid on account of the Contract Price, or to determine that

title to any of the work, materials or equipment has passed to the County free and clear of

any lien, claims, security interests or encumbrances, or that there may not be other matters

at issue between the County and the contractor that might affect the amount that should be

paid. The budget includes three pay request reviews.

TASK 6: CONTINGENCIES

Due to the complex nature of the work involving marine surveys and environmental

permitting, it is anticipated that additional work may be necessary such as additional field

work, stakeholders meetings, or agency coordination. Further, the dredging may be extended

to include additional shoaled in channels requiring additional construction services. A

contingency budget is recommended for these circumstances. All scopes of work under this

task must be reviewed and approved by the County prior to conducting the additional work.

Note: Meetings, site visits and professional services outside the scope of services

budgeted for can be provided as Additional Services.
