CENTRAL RENTON SEWER INTERCEPTOR RELINE & UPSIZE PROJECT
SUPPLEMENTAL WORK
SCOPE OF SERVICES
December 17, 2014
Per your request, this scope of services is furnished to the City of Renton (City). It summarizes
the supplemental engineering and related services to be performed by BHC Consultants, LLC
(BHC) and our subconsultant—Aspect (geotechnical engineering) in support of the City's
Central Renton Sewer Interceptor Reline and Upsize project.
This proposal is based on our understanding of the City's needs and requirements gained
during our meeting with you on November 17, 2014, as well as subsequent related discussions
and input.
Proposed Work Scope
The following efforts are anticipated.
• Task 008— Final Design and Preparation of Drawings and Technical Specifications
o Update drawings to reflect revised bid date - March 2015.
• Task 012—Project Management
o Documentation of additional work and preparation and execution of a contract
amendment and related efforts.
o Miscellaneous related project management including staff management, contracting,
invoicing, project progress/status reporting, etc. associated with the modified/expand
project and extended schedule.
o Communication and coordination with City staff, BHC staff, and others to exchange
information, provide assistance, discuss related issues, coordinate efforts, etc. asso-
ciated with the modified/expanded project and extended schedule.
*The budget assumes a limited, up to eight (8) calendar months, period ending no later
than August 30, 2015.
• Task 013— Support During Construction (New)
o Pre-Construction Conference —Attend a pre-construction conference. Contribute to
the agenda for the meeting and participate in the discussion of the technical aspects
of the project. BHC's Project Engineer will attend.
o Technical and General Project Support—At the City's request, assist with resolving
technical issues, questions, or problems, review and comment on select Contractor
submittals, clarifying or understanding the intended design and contract documents,
and reviewing proposals for changes in the work or design. As needed or appropri-
ate, provide supplemental instructions and/or drawings/sketches for clarification.
Provide related miscellaneous support and assistance during construction, including

tw
general communication and coordination with City staff and others to exchange in-
formation, provide assistance, discuss related issues, coordinate efforts, etc.
'Due to the difficulty in determining the extent of technical support that may
be desired/required during construction, a budget allowance of$5,500 has
been established for this task.
o Site Visit(s) During Construction - Make a site visit to review the work, and/or coordi-
nate with the City's staff and/or on-site construction observer. Once the work is sub-
stantially complete and ready for final inspection, attend a walk-through with the con-
tractor, City staff, and construction observer to support the preparation of a punch
list. For budgeting purposes, BHC's Project Engineer will attend up to two (2) site
visits/construction meetings for an average of four (4) hours each including prepara-
tion, travel, and attendance.
o Geotechnical Engineering Inspection/Testing Services - Provide for limited, on-call
geotechnical engineering inspection and/or testing services during construction to
verify that the soils or other materials being incorporated into the work meet the
requirements of the Contract Documents. Due to the difficulty in determining the
extent of services that may be required under this activity, a budget allowance of
$2,500 has been established for this activity.
o Record Drawings - Prepare record drawings for the project incorporating revisions to
the drawings as marked up on the contractor's record drawing set and as marked up
on the City inspector's record drawing set. An electronic copy on a CD and one full-
size set of the record drawings (printed on 22"x34" mylar) will be provided to the City.
The extent of work, which may be required under this activity, cannot be accurately
predicted, and therefore, a budget allowance of approximately $2,500 has been
established for this work.
Fee
Based on the attached hour effort estimate and related expenses, we estimate our fee for the
proposed supplemental engineering services and related efforts to be $18,423 which includes
$2,500 for a subconsultant and $155 for related reimbursable expenses. See the attached
Exhibit A (cont.) for further details.
