1.2 BACKGROUND

A. The Farmington District Office building was constructed in 2013 and consists of 30,000 square feet of floor area. It is a flat roof, steel-framed building with masonry and metal cladding, composed of a two-story open office area to the west and a single-story private office and public area to the east – the two-story open office area has an atrium that is open to a roof monitor that provides daylighting in the core of the building. The public portion of the building contains the entry lobby, reception area, and public restrooms, along with a Public Room and a Multi- Purpose

Room. The roof is accessible via a roof hatch and ladder located in the Mail Room.

B. Existing Mechanical Systems: The existing heating, ventilating, and air conditioning (HVAC) systems consist of two-stage rooftop mounted evaporative coolers with an underfloor air distribution system – most of the building has a raised floor system with an 18-inch deep plenum for air distribution. Two natural gas-fired modulating-condensing boilers have been installed to provide heat for the building, along with two hot water circulating pumps, air separator, and expansion tank. Fan-powered variable air volume (VAV) terminals with hot water reheat coils have been installed under the raised floor at the perimeter of the building, along with VAV and manual floor diffusers in the core of the building. The existing rooftop HVAC units are located in screened enclosures to the east and west of the central roof monitor.

HVAC SYSTEM IMPROVEMENTS

01010-2

The HVAC systems installed at the Farmington District Office have been problematic since construction on the building was completed. An abbreviated list of ongoing issues that have been experienced is as follows:

1. Even with remedial work completed at the end of the construction period, the underfloor air distribution plenum leaks supply air excessively, leading to comfort complaints due to lack of good air distribution.

2. The Multi-Purpose Room has been especially difficult to heat and cool properly. More generally, the entire east end of the building has been difficult to heat and cool properly.

3. The fan-powered VAV terminals and associated air filters located in the underfloor plenum are difficult to access for service and maintenance.

4. Dirt collecting in the floor diffusers is an ongoing maintenance issue. The dirt from people’s shoes causes both the manual damper and automatic damper mechanisms to jam and space temperature control suffers as a result.

5. Even with repeated investments and service contracts, the automatic control system (DDC

BAS or direct digital control building automation system) still does not operate correctly and requires manual operation and adjustment to achieve acceptable comfort conditions.

6. The two-stage evaporative cooling rooftop units require frequent maintenance and use an excessive amount of potable water for their operation.

7. The heating system failed during the winter of 2017/2018. District Office personnel had to be sent home due to the lack of heat, and the fix took time and was expensive. Repair parts for the boilers have been difficult or impossible to obtain in recent years.

8. The HVAC systems that are installed in the Farmington District Office are overly complex and are not standard, which has historically led to a lack of understanding on how they should be operated and maintained.

All of this affects employee and visitor comfort, along with limiting BLM maintenance staff productivity and effectiveness. Current energy use at this facility is also higher than it should be, especially considering that the facility has 67 kW of photovoltaic (PV) solar energy systems installed. Replacement of the existing HVAC systems with new high efficiency variable refrigerant flow (VRF) systems will improve occupant comfort, increase system reliability, and increase energy efficiency.

C. Existing Electrical Systems: The existing electrical system consists of a 1000A, 480/277V, three phase service. A 225 kVA dry-type transformer has been provided to power all of the 208/120V circuits in the building.

1.3 CLARIFICATION OF INTENT FOR EXECUTION OF WORK

A. The general intent of the contract is to leave as much of the existing building construction and furnishings in place as possible during execution of the Work. If the Contractor determines that more involved approaches to the work are required than what is described here, the Contractor shall state so in their proposal and include any additional costs in their bid prices. Specific clarifications of intent for the execution of the Work are as follows:

1. Systems Furniture: The intent is for the systems furniture in the open office areas to remain in place during the execution of the Work. Work surfaces (desktops) in

HVAC SYSTEM IMPROVEMENTS

01010-3 individual cubes may be removed as necessary for access. Furniture in private offices, conference rooms, etc. may be moved or removed as necessary for access.

2. Suspended Ceilings: The intent is to remove existing suspended ceiling tiles as necessary, but to leave the suspended ceiling grids in place as much as possible during the execution of the Work. If necessary, T-bar cross-pieces may be removed as necessary for access.

3. Gypsum Board Ceilings: The intent is to remove only as much of the gypsum board ceilings as necessary and to leave the ceiling joist structure in place as much as possible during the execution of the Work. The only modifications that should be required for the ceiling joist structure are any reframing required for the installation of ceiling-mounted fan coils and access doors.

4. Underfloor HVAC Equipment: The intent is to abandon the existing fan-powered VAV terminal units, ductwork, piping, conduit, and wiring in place below the raised floor. At the end of the project, the dampers in all unused floor registers shall be closed.

5. CMU Wall Openings: New cut and/or cored openings through CMU walls are small enough that no steel reinforcing should be required.

6. Protection of Existing Floors and Furnishings: Temporary floor protection (Ram Board or equal taped down to existing floors) shall be provided as necessary to protect the floors during execution of the work. Temporary protection (tarping) of furnishings shall be provided as necessary to protect furnishings during execution of the work.

CONSTRUCTION SCHEDULE

01320-1

SECTION 01320 – CONSTRUCTION SCHEDULE

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 the Government in monitoring the progress of the work, evaluating proposed changes, and processing the Contractor's monthly progress payment.

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 Government.

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 the 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.

01320-2

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.

1.3 SUBMITTALS

A. Electronic Copies: All schedules and reports submitted shall be posted on the Contractor’s FTP

(or cloud storage such as Google Drive, OneDrive, etc.) website, 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 a copy of the baseline schedule, complete to show entire schedule for entire construction period.

D. CPM Reports: Concurrent with CPM schedule, submit copies of each of the following computer-generated reports. Format for each activity in reports shall contain activity number, activity description, 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 copies of 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 a copy 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

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

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

2. Verify availability of qualified personnel needed to develop and update schedule.

3. Discuss constraints, including work stages, work area separations, interim milestones, partial Government occupancy, and temporary relocation of Government personnel.

4. Review schedule for work of separate and concurrent Government contracts.

5. Review time required for review of submittals and re-submittals.

6. Review requirements for tests and inspections by the Government and/or by independent testing and inspecting agencies.

7. Review time required for completion, startup, and commissioning procedures.

8. Review and finalize list of construction activities to be included in schedule.

9. Review baseline schedule comments, and resolve issues and progress on incorporating them.

10. Review procedures for updating schedule.

11. Discuss reporting requirements, and establish a protocol for naming and transmitting electronic schedules.

B. Contractor's Schedule Representative: Before or at the preconstruction conference, designate an authorized representative to be responsible for the preparation and maintenance of the

Construction Schedule. The Scheduler shall have prepared and maintained at least 5 previous schedules of similar size and complexity similar to this Contract, demonstrating proficiency in the use of scheduling software. The authorized representative will be responsible for preparing the Baseline Schedule, all required updates, revisions, Time Impact Analyses, and preparation of reports.

1.5 COORDINATION

A. Coordinate preparation and processing of schedules and reports with performance of construction activities, and with scheduling and reporting of separate and concurrent Contractors.

B. Coordinate Construction Baseline Schedule with the Schedule of Values, list of subcontracts, Submittals Schedule, progress reports, payment requests, and other required schedules and reports.

1. In developing the Construction Baseline Schedule, ensure that the Subcontractor’s work at all tiers, as well as the prime Contractor’s work, is included and coordinated.

2. Secure time commitments for performing critical elements of the Work from all parties involved.

3. Coordinate each construction activity in the network with other activities and schedule them in proper sequence.

2.1 SCHEDULE OF VALUES

A. Break down each lump-sum bid item into component work activities used in the schedule, for which progress payments may be requested. The work activities broken out within the schedule of values shall be integrated into and made a logical part of the construction baseline schedule submitted under this specification. The total costs for the component work activities shall equal the contract price for that lump-sum item. The Government may request data to verify accuracy of dollar values. Include mobilization, general condition costs, overhead and profit in the total dollar value of unit price items and in the component work activities for each lump- sum item; do not include mobilization, general condition costs, overhead or profit as a separate item.

B. The total cost of all items shall equal the contract price. The Schedule of Values shall form the basis for progress payments.

C. An acceptable Schedule of Values shall be agreed upon by the Contractor and the Government before the first progress payment is processed.

2.2 CONSTRUCTION SCHEDULE REQUIREMENTS

A. Construction Baseline Schedule: Prepare Construction Baseline Schedule using a computerized, resource-loaded, time-scaled CPM network analysis diagram for the Work.

1. Develop and finalize Construction Baseline Schedule so it can be accepted for use no later than 30 days after date established for the Notice of Award.

a. Failure to include any work item required for performance of this Contract shall not excuse Contractor from completing all work within applicable completion dates, regardless of Government’s acceptance of the schedule.

2. Establish procedures for monitoring and updating Construction Baseline Schedule and for reporting progress. Coordinate procedures with progress meeting and payment request dates.

B. Construction Baseline Schedule Preparation: Prepare a list of all activities required to complete the Work. Using the preliminary CPM network diagram, prepare a skeleton network to identify probable critical paths.

1. Activities: Indicate the estimated duration, sequence requirements, and relationship of each activity in relation to other activities.

2. Critical Path Activities: Identify critical path activities, including those for interim completion dates. Scheduled start and completion dates shall be consistent with Contract milestone dates.

3. Processing: Process data to produce output data on a computer-drawn, time-scaled network. Revise data, reorganize activity sequences, and reproduce as often as necessary to produce the CPM schedule within the limitations of the Contract Time.

4. The Construction Baseline Schedule as developed shall show the sequence and interdependence of activities required for complete performance of the work. Ensure all

HVAC SYSTEM IMPROVEMENTS

01320-5 work sequences are logical and the Construction Baseline Schedule shows a coordinated plan of the work.

5. Resource loading of each activity shall include all personnel by labor category and equipment type and capacity proposed to complete the activity in the duration shown.

6. Consider seasonal weather conditions in planning and scheduling all work influenced by high and low ambient temperatures, wind, or precipitation to ensure completion of all work within the contract time.

7. Time Frame: Proposed duration assigned to each activity shall be the Contractor's best estimate of time required to complete the activity considering the scope and resources planned for the activity.

a. An early finish date may be shown but the late finish date must be the same date as the last day of the contract period. An early completion schedule must contain the following:

1) Insert an activity titled “Project Float” as a successor to the last activity in the early project completion schedule network.

2) Add a milestone titled “Contract End Date” as a successor to the activity

“Project Float”.

3) Add duration to the activity “Project Float” as required so the milestone

“Contract End Date” equals the last day of the Contract Period.

b. Contract completion date shall not be changed by submission of a schedule that shows an early completion date.

c. The Contractor shall limit use of lead or lag durations between schedule activities.

d. Project Calendars: Develop and incorporate the following calendars:
