1.2 PROJECT NARRATIVE

A. The scope of work under this project includes replacing oil fired heating equipment with propane fired units and providing an above ground propane storage tank with vaporizer and underground distribution piping. The tank is sized for approximately six months of heating fuel requirement and one week of generator fuel requirement. It is assumed that the heating capacity of existing equipment is adequate to meet the building heating demand. Maintenance staff indicated that during peak winter, temperature in some portions of pipe gallery remains low and that affects the operation of pneumatic valves/controls. Some of the pipes are presently being heat traced to avoid operational problems. New propane fired infra-red heaters are proposed for the pipe gallery to enhance the temperature coverage. Additional scope includes replacing the fuel oil powered generator with a propane unit piped from the new above ground propane storage tank. One week of generator operation is accounted for in sizing the tank.

3 PART 3 EXECUTION

3 .1 IMPORT OF MATERIALS

A. Sources of rock, sand, gravel, earth, soil, or other imported natural material may be inspected for invasive non-native plants prior to acceptance. The contractor shall submit to the NPS Contracting Officer a list of proposed sources for import materials 30 calendar days in advance of importing material. The list shall also include the end use and any temporary storage requirements of those materials. NPS Natural Resources staff would inspect sources of materials that pose a risk, either by their end use or storage requirements, of allowing invasive non-native plants (also known as noxious weeds) to establish in the park. Materials may be rejected if non-native invasive plants are present at the source and seeds could be present in the material. At the discretion of the NPS Contracting Officer, potentially contaminated materials may be accepted if mitigating measures are implemented. Mitigation might include stripping the top 12 inches of source material, requiring fresh material stored less than 1 month, or sterilizing the material. Contaminated materials that contain fines and have an end-use on the surface would require sterilization before importing to the park. Import material shall be shipped directly from the source to the park without intermediary storage or staging. Shipping vessels shall be covered to prevent spillage or blowing of their contents while in transit. Materials must also be transported and stored such that they would not acquire invasive non-native plant seeds from adjacent vegetation.

B. The following is a list of import material sources within local region of Sequoia and Kings Canyon National Parks that have been used by past projects and inspected by the National Park Service. Utilization of one or more of these sources does not provide approval of the source and material but rather, the list is intended to provide contractors with information on sources that in the past have passed the NPS’s Natural Resource’s inspection. This may reduce contractors’ perceived risk that they may not have local knowledge of import material sources.

1. Lemon Cove Granite

2. Vulcan – Friant

3. Cemex – Lemon Cove

4. Vulcan - Sanger

3 .2 PROTECTION INSTALLATION

A. Provide temporary work limit fencing, tree trunk wrap, and tree barricades to protect existing trees, plants and critical root zones as directed by the Contracting Officer. Protections shall be in place before any excavation work or heavy equipment is allowed on site.

A. Only after all tree and plant protection has been installed, and the Contracting Officer has inspected and given written approval of the tree and plant protection, will the Contractor be allowed to begin excavation. All tree and plant protection shall be maintained throughout the duration of this project.

B. If any fencing, barriers, staking or marking, which designates protected areas, limits of demolition or work limits, is knocked down, moved or destroyed by the Contractor, the Contractor will immediately move the work operation to another area, wholly or in part, or suspend work operations, until the fence or other protection is repaired to the Contracting Officer's satisfaction at the Contractor's expense. Time lost due to such stoppage will not be considered basis for adjustment of completion date nor additional payment.

C. Parking vehicles and storing materials or supplies shall be confined to areas designated as staging areas on the plans or as specifically approved by Contracting Officer. Vehicle and material storage activities are strictly prohibited from protected and fenced sensitive soil and vegetation areas.

D. Fastening ropes, cables, or guys to existing trees and disposing of materials including, but not limited to paint, paint thinner, fiberglass materials, fiberglass thinners, concrete or cement residue, washings from cement or concrete mixers or any other material considered harmful by the Contracting Officer is prohibited anywhere in the project area.

E. Do not remove, injure, or destroy trees or other plants without prior approval of the Contracting Officer.

SECTION 01 32 16 – CONSTRUCTION SCHEDULE

PART 1 - GENERAL

1.1 SUMMARY

A. This Section consists of Construction Schedule requirements including but not limited to the following:

1. Schedule of Values

2. Construction Schedule Requirements.

3. Construction Schedule Updates.

4. Time Impact Analysis.

B. Purpose: The purpose of the Construction Schedule is to ensure adequate planning, coordination, scheduling, and reporting during execution of the work by the Contractor. The Construction Schedule will assist the Contractor and Contracting Officer in monitoring the progress of the work, evaluating proposed changes, and processing the Contractor's monthly progress payment.

1.2 DEFINITIONS

A. Activity: A discrete part of a project that can be identified for planning, scheduling, monitoring, and controlling the construction project. Activities included in a construction schedule consume time and resources.

1. Critical activities are activities on the critical path. They must start and finish on the planned early start and finish times.

2. Predecessor Activity: An activity that precedes another activity in the network.

3. Successor Activity: An activity that follows another activity in the network.

B. Cost Loading: The allocation of the Schedule of Values for the completion of an activity as scheduled. The sum of costs for all activities must equal the total Contract Sum, unless otherwise approved by the Contracting Officer.

C. CPM: Critical path method, which is a method of planning and scheduling a construction project where activities are arranged based on activity relationships. Network calculations determine when activities can be performed and the critical path of Project.

D. Critical Path: The longest connected chain of interdependent activities through the network schedule that establishes the minimum overall Project duration and contains no float.

E. Float: The measure of leeway in starting and completing an activity.

1. Float: Float is not for the exclusive use or benefit of either the Government or the Contractor but is jointly owned.

2. Free float is the amount of time an activity can be delayed without adversely affecting the early start of the successor activity.

SEKI - 157070 013216 - 2

3. Total float is the measure of leeway in starting or completing an activity without adversely affecting the planned Project completion date.

F. Resource Loading: The allocation of manpower and equipment necessary for the completion of an activity as scheduled.

G. Fragnet: A partial or fragmentary network that breaks down activities into smaller activities for greater detail.

1.3 SUBMITTALS

A. Electronic Copies: All schedules and reports submitted shall be on the NPS Share-File system, provided in the native electronic file format. It is the intent of the Government to limit the number of printed reports to only those reports determined by the project team to be essential.

B. Schedule of Values: After contract award and before the Pre-Construction conference submit a schedule of dollar values based on the Contract Price Schedule.

C. Construction Baseline Schedule: After contract award and before the Pre-Construction conference, submit two paper copies of baseline schedule, large enough to show entire schedule for entire construction period.

D. CPM Reports: Concurrent with CPM schedule, submit three paper copies of each of the following computer-generated reports. Format for each activity in reports shall contain activity number, activity description, cost and resource loading, original duration, remaining duration, early start date, early finish date, late start date, late finish date, and total float in calendar days.

1. Activity Report: List of all activities sorted by activity number and then early start date, or actual start date if known.

2. Logic Report: List of predecessor and successor tasks for all activities, sorted in ascending order by activity number and then early start date, or actual start date if known.

3. Total Float Report: List of all activities sorted in ascending order of total float.

E. Construction Schedule Updates: On or before the 7th day preceding the progress payment request date, submit estimates of the percent completion of each schedule activity and necessary supporting data.

F. Construction Schedule Revisions and Time Impact Analysis: For each Construction Schedule revision submit two paper copies of a Time Impact Analysis. Each Time Impact Analysis shall include a Fragmentary Network (Fragnet), incorporated into the currently accepted Construction Schedule, demonstrating how the Contractor proposes to incorporate a modification, change, delay, or Contractor request.

1.4 QUALITY ASSURANCE
