| BACKGROUND: |
In January 2013, a Task Order was issued to Hammond Engineering, Inc., on the Shadow Grove Stormwater Improvement Project, to include professional surveying and design services for this project.
Change Order #1, issued in February 2014, was for time only, adding an additional 545 days to complete the design, construction and as-built certification, which made the new completion date July 16, 2015. Just prior to bidding, the April 2014 storm event occurred.
Change Order #2, issued in April 2014, was an Additive Change Order, for $2,095.00, to compensate the design engineer for additional Subsurface Utility Engineering services. Upon completion of standard utility coordination, per the original scope, it was determined that more comprehensive services were needed to field-verify elevations of underground utilities. This included reallocation of remaining funds from other tasks within the project.
Change Order #3, issued in April 2015, an Additive Change Order, for $32,692.00, addressed damages caused by the April 2014 storm event and included work needed for the repairs and improvements to the Shadow Grove drainage project. Additional services included a current survey of damaged infrastructure and adjacent pond expansion parcels, with additional design to incorporate the repairs and stormwater facility expansion. This Change Order and the additional improvements are part of an application to FEMA for reimbursement.
Change Order #4, issued in December 2015, was an Additive Change Order, for $16,455.00, which added several design components to the plans. These additions included a base and alternate design for the outfall of the middle pond located at the end of Elcino Circle, structural design for retaining walls along a portion of the middle pond, additional surveying in the bottom pond south of Elcino Drive, and a sketch and legal for real estate acquisition to expand an existing drainage easement where it will completely contain the county ditch behind the homes along Shade Tree Circle. The alternate design was needed so the plans can be completed and ready for bid for either pond/outfall configuration, once the property issues are addressed on Elcino Circle. In consideration of the FEMA deadlines, these alternate plans were needed to keep the project moving. The additional surveying is needed to correctly depict changes the Road Division made during post-storm repairs in the lower retention pond. The legal description and sketch is needed to widen an existing easement so it will cover the entire existing county ditch.
This Change Order, #5, for an additional amount of $45,156.00, will provide structural engineering and drainage design services for the installation of sheet pile retaining walls along the extent of the middle pond on both sides to protect adjacent properties. Prior to this request, SIGMA Consulting provided cross-sections for the sheet pile retaining walls on a voucher. Since then, the scope of work has increased and in order to achieve a more sustainable product, additional design is required to accommodate drainage behind the sheet piles and also to provide for future downspout tie-ins. This work is part of an existing FEMA project and these additional design costs will be submitted for reimbursement. The state's representative (sub-grantee) has walked the site with county staff and has provided guidance on how the increased scope and Hazard Mitigation should be presented to FEMA for reimbursement. |
