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 decreased 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.

FARMINGTON DISTRICT OFFICE CONSTRUCTION SCHEDULE

HVAC SYSTEM IMPROVEMENTS 01320-1

SECTION 01320 – 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 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.

HVAC SYSTEM IMPROVEMENTS 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.
