The project is to remove and replace the EPDM membrane roofing system. Project includes removal and replacement of EPDM membrane, insulation board, and other roofing accessories as necessary. All materials to meet code and warranty. All work shall be performed in accordance with local codes, standards and enforcement.

Project Location: Lincoln Boyhood National Memorial Visitor Center. Park Address: 3027 E South Street, Lincoln City, IN 47552.

Description of Work: The Contractor shall furnish all personnel, equipment, tools, materials, supervision, and other items and services necessary to decommission, dispose of and replace the Visitor Center End Hall EPDM roofs and associated EPDM components. Work only to take place on roofs covering the Nancy Hanks Lincoln and Abraham Lincoln Halls of the Visitor Center.

Work only to include replacement of EPDM “gutter” portion of roofs. Roofing systems to be replaced are located at two separate sections of the building and located over the two end halls of the Visitor Center. Contractor shall start and finish roofing system replacement on one section before moving on to roof replacement of the other section. This requires all work from tear-off to installation be completed independently for one roof at a time. No work to take place on EPDM roof covering the cloister hallway, auditorium or office areas of the Visitor Center. Contractor shall limit foot traffic and install temporary walkway protection on existing EPDM roofing not being replaced. No work to take place on copper roof over end halls, except for necessary modifications to the outer 10 inch copper roof edge that transitions to EPDM. All work required by the project documents shall be accomplished by the contractor. Work must be performed to prevent damage to historic fabric of structure.

The Work includes the removal and replacement of the EPDM roof systems over the Visitor Center ends halls with a fully adhered 60 mil reinforced EPDM membrane system. Roof area replacement anticipated to be approximately 3,520 square feet. Work will include removal and replacement of existing EPDM roofing system to include; EPDM membrane, insulation board, limited roof decking as necessary, cast iron roof drain domes and clamping rings (4) and all necessary hardware and accessories to provide for a fully weathertight roofing system with a manufacturer's standard 20 year warranty. The new roof will include the addition of a protective cover board over the insulation board and below the EPDM membrane. All work to be performed according to manufacturer’s recommendations.

The intention of the Work is to not remove parapet capstones or copper roofing as both are in good condition. Copper parapet flashing and copper roof edge temporary modifications will be required as necessary to allow EPDM system removal and installation.

SECTION 01 32 16 – CONSTRUCTION SCHEDULE

PART 9 - GENERAL

9.1 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.

9.2 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.

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.

9.3 SUBMITTALS

A. Electronic Copies: All schedules and reports submitted shall be sent to the CO, 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 one digital (PDF) of baseline schedule, large enough to show entire schedule for entire construction period.

D. 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. Provide two paper copies and one digital (PDF).

E. Construction Schedule Revisions and Time Impact Analysis: For each Construction Schedule revision submit one digital (PDF) 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.

9.4 QUALITY ASSURANCE

A. The Contractor shall meet with the Contracting Officer on the day of the preconstruction conference to go over the following:

1. Review software limitations, content and format for reports.
