Scope of Work for Design-Build Services

I. General A. Introduction

The Monongahela National Forest requests engineering and construction services for the construction of a water line extension into the Stuart Recreation Area. This project is contingent on Midland Public Service District (MPSD) completing the Proposed Kelley Mountain, Poe Run, and Shavers Fork Water Line Extension, up to where this project starts. Construction of this project shall not begin until Midland PSD’s Proposed Kelley Mountain, Poe Run, and Shavers Fork Water Line Extension is finished to their specified endpoint which is the starting point for this project.

The projected completion date of MPSD Proposed Kelley Mountain, Poe Run, and Shavers Fork Water Line Extension project is April 2020.

The Design Builder (DB) shall provide all equipment, acquire required permits, supplies, personnel, supervision, materials, quality control, and incidentals for the complete survey, investigation, design, fabrication, and construction of the work described.

The DB shall perform all work in a safe and conscientious manner.

B. Description of Work

The project includes the engineering and construction of approximately 2,100 linear feet of various size waterline including boring underneath the Shaver’s Fork River. Six (6) inch water line shall be installed underneath the river. Two (2) inch waterline shall be installed approximately 1800 linear feet to the end point in Stuart Recreation Area Campground. The Contractor is responsible pre-design, design, permitting, and construction required, including but not limited to; tying into the existing waterline, furnishing and installing waterline, casings, river boring, gate valve boxes and covers, meter services, disinfection and testing, and accessories to complete the project.

C. Location

The projects are located on the Cheat Ranger District of the Monongahela National Forest, Randolph County, West Virginia. The project begins near the Shaver’s Fork River Bridge on Old Rt. 33 and ends inside Stuart Recreation Area Campground (location map attached).

D. Pre-Bid Tour

A pre-bid tour is planned as shown below.

Generally, Brief Phone Discussions will involve no more then 3 – 4 different parties and have a duration of less than 1 hour. The party requesting the BPD shall be responsible for organizing and setting up the call. BPD's are considered incidental to the contract with no separate reimbursements.

3. Conference Calls (CC): Contractor's personnel familiar with the work and subcontractors when the subject matter involves discussion of subcontractor's work, shall participate in conference calls identified within the contract or agreed to by both parties. The contractor shall be responsible for organizing and setting up all conference calls identified. Conference calls will ordinarily involve several personnel from the Forest Service and other interested parties.

IV. General Project Requirements

A. DESIGN ANALYSIS

The design analysis shall be a bound assembly, in one or more volumes of functional and engineering criteria and design information. The design analysis submitted for review shall include all information, narrative descriptions, catalog cuts, product information, project scope, confirmation notices, computations and all previously made review comments with the DB's annotations as necessary to support and describe the design developed. It shall be in such detail as to permit complete understanding of the project design. When brand names or equal are used to specify a product the design analysis shall contain catalog cuts and other information in sufficient detail to clearly identify the product and its saline characteristics. When products are specified by standards and not by name, the design analysis shall identify at least two sources of products meeting the listed standards. The design analysis shall be prepared to present the data in an organized manner for:

1. Review, approval, and record purposes.

2. Future re-evaluation and modification of construction.

3. Review and acceptance of submittals.

Design Calculations. Calculations shall be computed and checked by separate individuals. The names or initials of these individuals will be indicated on the page or insert carrying the calculations. Presentation will be clear and legible with a tabulation showing all design loads and conditions. The source of loading conditions, formulas, and references will be identified. Assumptions and conclusions will be explained and cross-referencing will be clear. Software programs, such as Mathcad are the preferred method for presenting lengthy or complex analysis.

Use of Computer Programs. When computer programs are used, the design analysis should include a complete listing of the input and output data, and calculations necessary for preparation of the input data. Input should be annotated to facilitate a reviewer's verification of data. Computer output should be in a format that identifies results by proper column headings and line identification keyed to a sketch of the structure if necessary. Voluminous output data may be included in a separate volume or, output presentation may be limited to key sections or to typical results when output is repetitive. Results should be verified by a "ball park" hand analysis. The required level of verification is dependent on such factors as complexity of analysis, importance of results and level of confidence in the program. Approved computer programs will be those commonly used programs judged to be reliable and thoroughly debugged.

Other Data. Codes, manuals, special investigations and reports are to be considered and used as applicable.

Generally, font size less then 3/32” will not be accepted without prior approval. A drawing scale bar shall be provided on each sheet, for each of the different scales represented on that sheet.

At each of the intermediate submission stages, the drawings shall be provided in hardcopy and electronic as required in the Submittal/Delivery schedule. If the contractor is required to maintain a FTP site then copies of all documents shall be posted in PDF format.

Hardcopy drawings shall be provided in D size format unless half size is specifically requested. When requested, drawings shall be made available in AutoCAD, DWG format.
