Template Date 4-10-20 | Page 18 of 45

• Fast track construction: 100% Complete DB Construction Documents affecting work to be constructed.

Purpose: Project schedule ensures adequate planning, coordinating, scheduling, and reporting of DB

Contractor’s design and construction activities. Project schedule will assist DB Contractor and

Contracting Officer to monitor work progress, evaluate proposed changes, and process DB Contractor's monthly progress payment requests.

Software: Latest version of Microsoft Project, Primavera Project Planner, SureTrak, or approved equal.

Schedule Development: Project schedule shall cover entire contract period. Late finish date is same as contract’s established completion date.

DB Contractor shall use Critical Path Method (CPM) with limited use of lead or lag durations between schedule activities. DB Contractor's project schedule shall consist of procurement activities (including mobilization, submittal, and fabrication and delivery of key and long-lead procurement items) and construction activities.

DB Contractor's project schedule shall consist of, but not be limited to, the following for each activity:

• Identify activities and numbers numerically (maximum 5-digit). Number activities in increments of 10.

• Concisely describe work represented by activity (maximum 48 characters). Avoid using non-standard abbreviations. Limit work related to each activity to one work trade.

• Activity duration shall be in whole working days with maximum duration 15 work days each, unless otherwise approved by Contracting Officer, except for non-construction activities including mobilization, shop drawing and sample submittals, fabrication of materials, delivery of materials and equipment, and concrete curing.

DB Contractor shall ensure project schedule includes own work and Subcontractor work.

Project schedule shall show sequence and interdependence of activities required for complete performance of work and shall be cost and resource loaded. DB Contractor shall ensure work sequences are logical and project schedule shows a coordinated work plan. Proposed durations assigned to each activity shall be DB Contractor's best estimate of time required to complete activity, considering scope and resources planned. Resource loading of each activity shall list personnel by labor category and equipment type, and capacity proposed to complete activity in duration shown. Include permit requirements and constraints. Consider and include seasonal weather conditions in planning and scheduling of work influenced by high or low ambient temperatures and wind and/or precipitation, to ensure completion of work within contract time.

Project Schedule Updates

Monthly updates: Monthly updates of project schedule shall be an integral part and basic element of estimate upon which progress payments shall be made under this contract. If, in judgment of Contracting

Officer, DB Contractor fails or refuses to provide schedule of values and complete schedule update or revision as specified hereinafter, DB Contractor shall be deemed to have not provided required information upon which progress payment may be made and shall be subject to retainage of a portion of the payment.

Template Date 4-10-20 | Page 19 of 45

Narrative: Include in report:

• Brief description actual progress made during update period.

• Actual and potential delaying activities.

• Impediments to progress.

• Issues related to inclement weather.

• Progress toward established milestones.

• Project float.

• Brief description of work anticipated to be performed in next month.

• Identify minor revisions to schedule for evaluation and accepted or rejected.

As work progresses, indicate Actual Completion percentage for each activity. If schedule update shows late finish date after contract completion date, at a minimum, include the following in narrative with submission:

• Known delays.

• Actions taken to get back on schedule.

• Pending modifications.

• Impediments or constraints affecting progress.

Progress Payments: Update currently accepted construction schedule monthly. If DB Contractor fails to provide monthly updates or revisions to currently accepted construction schedule, a portion of monthly payment may be retained until updates/revisions made.

Time Impact Analysis for Contract Modifications, Changes, Delays, and Contractor Requests

Requirements: When contract modifications or changes are initiated, delays are experienced, or DB

Contractor revises project schedule, DB Contractor shall submit to Contracting Officer a written time impact analysis illustrating influence of each modification, change, delay, or DB Contractor’s request on the contract time.

• Time Extensions: Activity delays shall not automatically mean an extension of contract time is warranted or due to DB Contractor. It is possible that modification, change, or delay will not affect existing critical activities or cause non-critical activities to become critical. A modification, change, or delay may result in only absorbing a part of available total float that may exist within an activity chain of the project schedule, thereby not effecting the contract time.

Time extensions will be granted according with terms of contract.

• Float: Float is not for exclusive use or benefit for NPS or DB Contractor. Extension of contract time is granted only to extent the equitable time adjustments to activity or activities affected by modification, change, or delay exceeds total (positive or zero) float available on a particular activity.

Template Date 4-10-20 | Page 23 of 45

Exotic Vegetation and Noxious Weeds: Prevent introduction and minimize spread of exotic vegetation and noxious weeds. Incorporate following procedures:

• Obtain fill, rock, or additional topsoil needed from a Government approved source.

• Use approved native seed and/or plants and revegetate areas disturbed by construction.

Vegetation Salvage and Revegetation Plan: Required for this project. For revegetation efforts, use approved native species and/or native seed and incorporate Park policies regarding vegetation and site restoration. Consider use of native species, plant salvage potential, exotic vegetation and noxious weeds, and pedestrian barriers. Policy related to revegetation will be referenced in NPS Management Policies

2006 (Section 9.1.3.2).

Special Status Species: To protect unknown or undiscovered threatened, endangered, or special status species, construction contract will include provisions for these discoveries. DB Contractor should contact Park for direction to evaluate special species at the site.

Visitor Experience: Incorporate following mitigation measures into action alternatives to minimize impacts of construction activities on visitor experience:

Air and Water Pollution Control: Air quality impacts are expected to be temporary and localized. To minimize these impacts, take following actions:

• To reduce tailpipe emissions, do not leave construction equipment idling longer than necessary for safety and mechanical reasons.

• To reduce construction dust, apply water to problem areas. Limit equipment to fenced project area to minimize soil disturbance and dust generation.

• Take necessary reasonable measures to reduce air and water pollution with material or equipment used during construction. Keep volatile wastes in covered containers.

• Storm Water Pollution Prevention Plan (SWPPP): Submit a SWPPP, according to applicable

State Water Resources Control Board's (SWRCB) requirements, to Contracting Officer for approval. (See Technical Requirements.) Before starting construction, DB Contractor shall implement approved SWPPP.
