Scope of Work Preliminary Engineering Design and Construction Cost Estimates Howland Dam Bypass Channel

Transcription

1 Scope of Work Preliminary Engineering Design and Construction Cost Estimates Howland Dam Bypass Channel The Penobscot River Restoration Trust (the Trust) is soliciting bids for conceptual and preliminary engineering design for the construction of a bypass channel for fish passage at the Howland Dam, located on the Piscataquis River in Howland, Maine. The Trust holds an option to purchase the dam and construct the bypass, if feasible. In order to exercise this option, the Trust must be prepared to file complete applications on June 1, 2008 with the Federal Energy Regulatory Commission (FERC), the Maine Department of Environmental Protection (DEP), and the US Army Corps of Engineers (USACOE). With this proposal, we are seeking engineering designs sufficient to inform these applications. The Penobscot Trust reserves the right to request final engineering design and construction administration services from the same consultant or consulting team hired for this preliminary portion of the design work, at the discretion of the Trust. Disclaimer: This RFP does not commit the Penobscot Partners to award a contract or to pay any costs incurred during the preparation of the proposal. The Penobscot Partners reserves the right to reject any or all of the proposals for completing this work. The Penobscot Partners also reserves the right to eliminate the need for the selected consultant to complete one or more tasks, pending the outcome of preceding related tasks or issues, and/or the availability of project partners to complete that task. Project Description The Penobscot River Restoration Project is concerned with several hydroelectric projects in the Penobscot River basin, which is located in central Maine between the Saint John River watershed (to the north), the Saint Croix River watershed (to the east), and the Kennebec River watershed (to the west). The Penobscot River has a drainage basin area of about 8,750 square miles and a length of 125 miles, north to south. The maximum width for the drainage basin is about 115 miles, making the Penobscot River the second largest in New England. The Trust intends to purchase and remove the Veazie Project (FERC No. 2403), and the Great Works Project (FERC No. 2312). At the Howland Project (FERC No. 2721), the Trust intends to decommission the hydroelectric facilities and construct a bypass channel to provide for unobstructed upstream fish passage. The Howland Project is located on the Piscataquis River, a tributary to the Penobscot that enters the system approximately 20 miles above the Milford Dam in Old Town. PPL Maine currently owns and operates these three projects. The Howland Hydroelectric Generating Facility (Howland Project) is located on Bridge Street in Howland, Maine. The site is approximately 500 feet upstream of the confluence of the Piscataquis River with the Penobscot River. The site is accessible off of Bridge Street from the County Road to the south of the site. The site includes the dam abutment that crosses the river, a

2 two-level brick and concrete generating building, and an electrical transformer substation enclosed by a chain-link fence, which is all south of the Piscataquis River and encompasses 1-½ acres. The building is believed to have been constructed around 1916 and currently houses all three hydroelectric generators. Some other portions of the site consist of gravel parking areas and building foundation debris, including concrete, bricks, and metal. The remaining upstream portions of the site are undeveloped as well as the remaining downstream portions. The site s topography is generally flat and slopes to the north and west towards the Piscataquis and Penobscot River. The elevation of this site is 150 feet NGVD. Project Facilities The Howland Dam was constructed in 1916 by the Howland Pulp and Paper Company. The Howland Dam hydroelectric facility is operated as a run-of-the-river facility, with inflow to the impoundment equal to the outflow from the dam and powerhouse. The Howland facility has a FERC license (FERC No. 2721). The Project dam is a concrete gravity design that was constructed on existing rock outcrop. The dam spillway is approximately 570 feet long and has an average height of nine feet, exclusive of flashboards. The dam was designed to carry 3-foot 9-inch high flashboards. The operating head for hydroelectric generation is about 17 feet, with flashboards in place. The upstream impoundment has a surface area of 270 acres, with a normal headpond elevation of feet (top of flashboards). The impoundment is approximately 4.7 miles long and extends from the dam to the upstream area of Doe Island. The dam consists of a foot long concrete cutoff at the north embankment of the dam, a 6-foot long left non-overflow abutment, a 570-foot long concrete spillway, an 85-foot long section containing gated spillway with four 9-foot by 9-foot steel roller flood gates and a abandoned fishway, a 20-foot long non-overflow section containing the exit of the upstream fishway and a 76-foot long forebay entrance deck located immediately upstream of the powerhouse. The Howland dam is also equipped with a fishway that was constructed by the Bangor Hydroelectric Company in The fishway provides limited upstream passage for anadromous and catadromous fish via a four-foot wide concrete Denil fishway with wooden baffles located adjacent to the powerhouse. The current fishway replaced the original pool and weir fishway which became inoperable in the 1930s. Downstream fish passage is provided through operation of the existing 5-foot 9-inch wide trash sluice located adjacent to the trashracks at the Howland project site. In 1993, downstream fish passage was enhanced by the installation of a 3-foot 6-inch deep bellmouth weir. In 1994, new trashracks with one-inch clear spacing were installed as a physical deterrent to migratory fish. The Piscataquis River is approximately 65 miles long and drains an area of 1,500 square miles. The largest lakes within the drainage include Sebec Lake (6,995 acres), Schoodic Lake (6,990 acres), and Seboeis Lake (4,096 acres). Together with the Pleasant River, these lakes account for 62 percent of the drainage area of the Piscataquis River basin. The average annual flow at the mouth of the Piscataquis River is 2,500 cfs.

3 Current Project Operations The Howland Hydroelectric Project is operated as a run-of-river facility. The hydraulic capacity of the turbines is approximately 1,710 cfs. On an annual basis, this turbine capacity is exceeded approximately 47 percent of the time, while the capacity of the turbines and the gates (5,310 cfs) is exceeded approximately 16 percent of the time. The normal impoundment elevation is feet and is maintained when river flows are at or below the hydraulic capacity of the units and the gates. When river flows exceed the hydraulic capacity of the units and the gates, water spills over the flashboards. When the gates are closed and river flow is at 2,500 cfs (average annual flow), the impoundment elevation is When the water reaches a height of two feet over the top of the flashboards, the boards begin to fall. The total hydraulic capacity of the gated and ungated spillway is 55,100 cfs before the deck of the gated spillway The Trust intends to decommission the hydroelectric facility at the Howland Dam, and upon approval of the preliminary design by state and federal fisheries agencies, construct a fish bypass channel around the dam across land now owned by the town of Howland and occupied by several abandoned industrial buildings. That property has been the subject of investigation and clean-up by the Maine Department of Environmental Protection, and a Voluntary Remedial Action Plan (VRAP) has been completed by the town of Howland to allow for future use of the site (Campbell Environmental Group, Inc., 2005). Scope of Services The consultant shall provide detail on their approach, deliverables, and cost for each of the following tasks and subtasks: Task 1: Project Start-Up and Coordination Task 2: Site Investigation and Due Diligence Task 3: Engineering Analyses, Conceptual Design, and Preliminary Design Task 4: Construction Cost Estimate Task 5: Renderings These tasks are described in detail below.

4 TASK 1 PROJECT START-UP AND COORDINATION Task 1.1 Review Existing Materials The consultant shall familiarize themselves with the project site and all of the preliminary data and reports that have already been completed for the Howland project. These include 1 : Campbell Environmental Group, Inc Phase I Environmental Site Assessment, Old Howland Tannery Property, 20 Old County Road, Howland, Maine. Campbell Environmental Group, Inc Phase II Environmental Site Assessment, Old Howland Tannery Property, 20 Old County Road, Howland, Maine.

Prepared for: Natural Resources Council of Maine. Woodlot Associates Infrastructure and Natural Resource Identification: Veazie, Great Works, and Howland Dam Impoundments. Prepared for: HydroTerra Environmental Services. Reports for two additional studies that are nearing completion (shoreline survey and bathymetrysediment characterization) will likely be completed by the time the Notice to Proceed (NTP) for this work is issued. A revised 1-D hydraulic model for the Howland site and associated mapping will also be complete. These will be provided to the selected contractor and must be reviewed as part of this task along with the existing data and reports listed above. Identify data gaps or deficiencies that need to be addressed in order to successfully complete the engineering work needed. Document any data gaps or deficiencies in a letter report to be completed within 15 days of the issuance of the Notice to Proceed (NTP).

5 resources agencies, and regulators. Regular communication will be an important part of ensuring that this multi-partner project runs smoothly The bypass channel will be constructed across property owned by the Town of Howland. It is therefore essential that the contractor maintain open communications with the Town Manager and/or other designated representative to coordinate site access and other local concerns. It is also important for the contractor to present to town officials and/or the public at key points in the design process. The contractor will be required to make three formal presentations to the town one when a conceptual design has been completed, for input from town officials on aspects of the design that may affect town interests; and two during the preliminary design process. For the three meetings at which the town will participate, prepare appropriate visual displays photo or artist s renderings and/or scale models to assist the town in visualizing details of the design. These three meetings will also be used to obtain comments from the fisheries agencies. We anticipate the following meetings will be required: Project kick off meeting and site visit with Trust and partners (See also Deliverables List, Task 1) Initial planning meetings (See also Deliverables List, Task 1) o with fisheries agencies to discuss fish passage design parameters o with Town of Howland to discuss site planning. Conceptual design meetings (See also Deliverables List, Task 3, Meeting 1) o with Trust and partners o with fisheries agencies and Town of Howland Preliminary design meetings (See also Deliverables List, Task 3, Meeting 2 and Meeting 3) o with Trust and partners o with fisheries agencies and Town of Howland Permit application meetings with Trust and Kleinschmidt Associates (See also Deliverables List, Task 1) o Draft application o Final application Regular coordination via conference call with Kleinschmidt Associates, Trust, and partners TASK 2 SITE INVESTIGATION AND DUE DILIGENCE Task 2.1 Utility Location The consultant shall contact the local municipalities and utility companies, including DIGSAFE, to obtain any above- and below- ground utility mapping in, or near, the project work area. The consultant shall depict the locations of these utilities on the base map. If utilities are determined to be located within or adjacent to the roadway or planned work area, the utilities shall be depicted and labeled and their specific location (e.g., depth) identified on plans. Task 2.2 Topographic Base Mapping The consultant shall prepare 1-foot contour base mapping sufficient to support concept and preliminary engineering design plans and construction documents for the bypass channel and any needed dam repairs. The survey shall be referenced vertically to NAVD 1988 and horizontally to UTM Zone 19 NAD83. The topographic map shall have an accuracy of 0.5 feet or better and

6 be prepared and stamped by a professional land surveyor (PLS). (See also Task 3.4 Existing Conditions Plan.) Task 2.3 Resource Area Delineation All regulated resources in the vicinity of the project work area will need to be identified, delineated, and depicted on the project base maps. Notes on resources in the project area (e.g., FEMA flood zones) shall be added to the base maps, as needed for permitting purposes. The appropriate wetland delineation data forms shall be completed for inclusion with project permit applications being prepared by the Trust s management consultant. (See also Task 3.4 Existing Conditions Plan.) Task 2.4 Property Ownership Determine the property lines in the vicinity of the site and proposed staging areas for depiction on the base map and project plans. Determine the need for any easement or property transfer to construct the bypass channel at site. (See also Task 3.4 Existing Conditions Plan.) Task 2.5 Dam Inspection Perform an inspection of the Howland Dam for the purposes of determining its structural condition and identifying any upgrades or design modifications necessary to bring it into full repair and dam safety compliance. The inspection should consider the proposed bypass channel and potentially necessary site improvements to support it, and these considerations should be reflected in the inspection report recommendations. The dam inspection report should be submitted to the Trust and project partners within 45 days of the project kickoff meeting. Task 2.6 Geotechnical and Soils Investigation The consultant shall conduct a geotechnical investigation necessary to inform design of the bypass channel. We anticipate this will include borings along potential bypass channel configurations to determine depth to bedrock, soil and substrata permeability, etc. This task will also include geotechnical investigations to support other site improvements contemplated as part of the bypass channel and/or dam inspection recommendations. Review existing Phase I Environmental Site Assessment prepared by Summit Environmental for the Howland Dam and powerhouse as well as the Phase I and II Environmental Site Assessments for the Old Howland Tannery Property prepared by Campbell. Based upon review of these materials, and in consultation with the Maine Department of Environmental Protection (as required under the VRAP), prepare and implement a supplementary soils investigation plan, as needed, consistent with the requirements of the Voluntary Remediation Action Plan between the Town of Howland and the Maine DEP, in consultation with Maine DEP staff and the town of Howland. Any necessary soils investigations should include all physical and chemical analyses necessary to inform design and potential disposal needs. The results of the geotechnical investigations and any necessary supplementary soils investigations, including potential soil disposal management options, will be presented in a

7 report to the Trust and partners with the laboratory analyses attached. This report will be submitted within 45 days of the project kickoff meeting. TASK 3 ENGINEERING ANALYSES, CONCEPTUAL DESIGN, AND PRELIMINARY DESIGN Complete concept and preliminary (30-50%) engineering design plans of the Howland bypass channel in close consultation and coordination with the trust, its management consultant, state and federal resource agencies, regulatory authorities, and project partners. Regular design meetings should be conducted to ensure the transparency of this process and the full consultation with the interested parties. Under this task, the consultant shall develop conceptual and preliminary (30-50%) engineering plans using CADD software suitable for regulatory permitting and cost estimation. The Trust anticipates that the consultant will need to conduct the following tasks to develop the preliminary engineering plans. Task 3.1 Concept Designs Based on the work performed in Tasks 1 and 2, and paying particular attention to the preliminary hydraulic analyses and design considerations presented by MMI (2007), prepare three (3) alternative conceptual engineering design plans for review by the agencies, regulatory authorities, and project partners within 45 days of the project kick-off meeting (see Task 1). Attend two (2) meetings to present concepts designs and receive feedback. The first meeting will be with the Trust and project partners followed by a second meeting with the regulators. The intent of the meetings will be to receive feedback on the alternative conceptual designs and achieve concurrence with the Trust, project partners, and regulators on up to two (2) alternatives to carry through to Task 3.2. Task 3.2 Hydrology, Hydraulics, and Fish Passage Analyses A calibrated, HEC-RAS water surface profile model has been developed for the site and will be provided to the contractor. Mean annual, mean monthly, and August median flows have been estimated for the Piscataquis River at the site, as well as the Penobscot River below the Piscataquis confluence (the tailwater condition), based on long-term USGS gage records. These estimates will also be made available to the contractor. The contractor may need to develop flood frequency estimates for the Piscataquis River at the site using the long-term gage record at Medford, ME (USGS Gage No ). The HEC-RAS model can be modified and used to test proposed split-flow configurations that simulate the bypass channel concept designs. However, we are interested to have tail water attraction flows analyzed in detail and we understand that a computational fluid dynamics model that simulates the velocity vectors below the spillway near the bypass entrance is necessary to do so. The contractor should propose the most effective approach to model all aspects of the project site to best understand fish passage conditions in the bypass channel and attraction flow concerns in the tailrace. The contractor should demonstrate in their proposal not only capacity for the

8 necessary hydraulic modeling and analyses, but also experience working with fish behavior, particular fish behavior within and below fishways. Successful design of the bypass requires construction of a bypass channel that will provide suitable depths, velocities, zones of passage, and attraction flows for upstream and downstream for all of the target species Atlantic salmon, alewife, blueback herring, American shad, American eel, and sea lamprey throughout the migratory season. Careful attention to predicting how fish will behave in response to the bypass channel s design will be critical. Evaluate upstream fish passage in the proposed bypass channel across a range of operating flows from minimum flow conditions up to 9,000 cfs. Include an assessment of varying Penobscot River elevations and how these affect hydraulics within the bypass channel. Determine water depths, widths and velocities in the bypass across the full range of flows. Relate these hydraulic conditions to swimming abilities of target species Atlantic salmon, American shad, alewife, blueback herring, sea lamprey and American eel. Assess attraction flow conditions in the Howland Dam tailrace in relation to the proposed bypass channel entrance. Assess the need, and potential methods, to enhance attraction flow under high flow and other conditions using the existing powerhouse, flood gates, or other existing structures. Also assess the hydraulic conditions for downstream fish passage at the spillway and in the tailrace. Estimate water surface profiles and hydraulic parameters for the river and proposed bypass channel for flood discharges with 10, 50, and 100-year recurrence frequencies to understand proposed project performance under flood conditions and inform design. Analyze, and address in the design, the potential for scour or other impacts at upstream infrastructure under proposed conditions for the range of flow conditions. This will include, but not be limited to, an assessment of the two bridges most immediately upstream of the Howland Dam and an upstream pipeline identified by Woodlot (2007). Review Woodlot (2007) to identify other infrastructure likely to be affected by the proposed project and verify with a field inspection. Any necessary infrastructure retrofits should be identified and carried forward into the design. Results of the hydrology, hydraulics, and fish passage analyses for up to two concept designs will be summarized in a draft report. The report should describe all hydrologic calculations, input data (i.e., bathymetric data and cross sections), model assumptions and boundary conditions, model calibration, and hydraulic modeling results. Include detailed model results in appendices to the report with important summary results and graphics (e.g., water surface profiles, cross-sections) in the main body. The draft report should be submitted within 60 days of completion of Task 3.1 (Trust selection of up to two alternatives to be evaluated in this task). The consultant will present the results of these analyses at a meeting with the Trust and project partners and at a second meeting with regulators. Based on the input from these meetings, a preferred alternative will be chosen by the Trust and project partners and any necessary modifications to the preferred alternative will be made in the preliminary design phase. The draft hydrology, hydraulics, and fish passage analyses report will be finalized based on these revisions and submitted with the preliminary design plans as an attachment to the preliminary design report (See Task 3.4). Water surface profiles, and multiple cross-sections, for the river and bypass channel for the preferred alternative during expected low, normal, and high operating flows must be shown on the preliminary design drawings.

9 Task 3.3 Sorting/Counting Facility Feasibility Some fisheries agencies have expressed a desire to include in the bypass design a trapping, sorting, and counting facility. This facility would be used to evaluate fish passage success, and, potentially, to prevent upstream passage of non-native fish species, particularly northern pike and black crappie. Determine the feasibility,of such a facility that must allow passage of all target species, but prevent passage of northern pike and/or black crappie. If feasible, include as an option in the preliminary design (Task 3.4) and provide estimated additional construction, operations, and maintenance costs (Task 4). The results of these analyses should be included in the design report described below. Task 3.4 Preliminary Design Using the information developed through the above tasks and in the work previously performed by others, the consultant shall develop preliminary engineering design plan sets suitable for regulatory review by the Maine Department of Environmental Protection, United States Army Corps or Engineers, Federal Energy Regulatory Commission, and local regulatory jurisdictions. The plans shall include scaled plan views, profiles, typical sections and all relevant supporting data. The plans shall include the following: Existing Conditions Plans. These plans shall include topography and spot elevations; titles of the adjacent roadways and water bodies; locations of soil borings; locations of known subsurface features; locations of utilities; and all drainage facilities and associated appurtenances in the project area. The plans shall also include wetland delineation flags and boundaries; titles of all regulated resource areas and their associated buffer zones (including the limits of the 100-year floodplain and flood zone); and property lines and related information compiled from existing town maps and records and results of Task 2 of this SOW. The plans shall include a base map for the project work area, as well as a broader, larger-scale map depicting the entire Howland Dam site and areas potentially affected by the project (e.g., staging areas). Excavation and Grading Plans. These plans shall depict the proposed work associated with constructing the bypass: channel design (slope, materials, elevations), sediment removal areas and disposal and/or stockpiling areas, bioengineering practices, and any grade control structures. Site access and limits of disturbance shall be depicted on this plan. Erosion and Sediment Control Plan. These plans and/or notes shall clearly indicate any inwater or land-based controls required for site stability and fulfilling regulatory requirements. Proposed Conditions Plan. This plan shall clearly depict the bypass channel, other areas of the site to be improved to support its construction (e.g., infrastructure retrofits as needed), and other project features (e.g., water control structures). Planting Plan. Note that all plant materials designated to be planted in the project area shall be native species. The draft plan shall include a summary schedule table indicating plant species, size, number, delivery type, spacing, and other requirements. The consultant shall also provide planting and seeding notes. Water Control, Temporary Diversion, and Dewatering Plan.

10 Construction Sequence. These plans or notes shall describe all work items and include equipment access and staging area needs. Profiles, Cross-Sections, and Typical Details. These figures shall address all pertinent work items and design features sufficient for permitting purposes. In particular, profile and crosssection views of bypass channel and any water control or grade control structures should be shown, including low flow channel, overbank floodplain grades, and expected water levels in bypass during low, normal and high operating flows and flood flows. The plans shall clearly depict the locations, and quantities, of wetland resource areas and potential project impacts to these areas and their associated buffer zones. Areas of proposed excavation, fill placement, water control and handling methods, and potential construction staging areas shall be shown. All requisite information for securing regulatory approvals shall be included in these plans. The consultant shall submit, within 60 days of Trust and partner identification of a preferred alternative (See Task 3.2), one (1) electronic and ten (10) hard-copy sets of the draft preliminary (30-50%) design engineering plans to the Trust and project partners for review and comment. A design report summarizing all data and analysis will also be submitted at this time (1 digital copy and 10 hard copies.) The consultant will present the draft preliminary design plans and report at a meeting with the Trust and project partners and at a second meeting with regulators. The consultant shall then, based on Trust and project partner comments, revise the plans and design report as needed and resubmit within 14 days of comment receipt. The consultant shall submit 1 electronic copy and ten (10) hard copies of the revised preliminary design plans and design report. The revised plans shall be stamped and signed by a Maine-licensed PE. TASK 4 CONSTRUCTION COST ESTIMATE The consultant shall compute preliminary quantities and prepare a preliminary engineer s estimate of probable construction costs for the bypass channel and any necessary additional site work to support its construction. These estimates shall accompany the draft and final preliminary engineering plans submitted to the Trust as described in Task 3.4. Provide separate cost estimates for the annual operations and maintenance cost for the bypass channel as well as the annual operations and maintenance cost of a fish trapping/sorting/exclusion facility. TASK 5 RENDERINGS Prepare two (2) renderings, or photo-renderings, of the preferred alternative. Views and method of rendering will be determined by the Trust and project partners once a preliminary design for the bypass channel has been selected.
