Commissioning Scope

Commissioning (Cx) is a systematic process of observing and documenting that a building’s systems installation, calibration, and performance meets both the Owner’s Project

Requirements (OPR) and the design team’s Basis of Design (BOD). For this project the schematic design documents and narratives will serve as the OPR and BOD. In order to achieve the maximum benefit from the Cx process, it is recommended that Cx begin during the design phase of the project to provide quality control of documentation for the systems to be commissioned and continue through construction, acceptance, and post-occupancy. In accordance with Guiding Principles for Federal Leadership in High Performance and

Sustainable Buildings, the commissioning process is intended to achieve specific goals in each phase of the project.

DESIGN PHASE: Commissioning during design is intended to achieve the following objectives:

• Review 100% design development documents prior to start of construction documents phase.

• Review construction documents, including OPR and MEP BOD, at 100% submittals.

• Incorporate the Cx requirements into the project by issuing the Cx specifications.

Introduction

The Owner’s Project Requirements (OPR) document is used to articulate the most important goals and objectives of the project from the point of view of the owner. The OPR is a detailed collection of the functional requirements of a project and the expectation of the building’s use and operation. This document is intended for use by the owner, design team, construction team, operation and maintenance staff, future renovation teams, and anyone who needs access to the original project information. The OPR forms the basis from which design, construction, operation and acceptance decisions are made. Each item of the OPR may have defined performance and acceptance criteria. Those that can be benchmarked should have the benchmark defined in specific terms and measurement.

During the course of design and construction, the OPR is updated to reflect changes to the original project goals. Updates to the OPR during the design and construction process are primarily the responsibility of the owner.

This OPR is a precursor and companion to the Basis of Design (BOD) document that provides detailed information on how the owner’s requirements are to be met through the development of the design documents, and/or implementation during construction, and/or operation. The

BOD is developed by the design team to reflect the requirements as specified in this OPR.

To meet BLM requirements, the owner’s intent is for the completed Fire Station to be compliant with the five Federal Guiding Principles for High Performance and Sustainable

Buildings. Requirements and strategies outlined in this document are driven by that goal.

Overview of Project

The Bureau of Land Management (BLM) has a strong commitment to high quality building construction, including sustainable design. In 2006, the BLM furthered their commitment to sustainability by pursuing compliance with the Federal Guiding Principles for High Performance and Sustainable Buildings (GP’s or Guiding Principles) on all new building projects.

The project referenced in this document will be the new Fire Station for the Weaver Mountain

BLM site. It will be a statement of commitment to the environment and a showcase for the community and the public that BLM serves.

The building designers should pursue sustainable objectives both within and outside the

Guiding Principles whenever possible. BLM’s commitment to sustainability is consistent with the desire to have integrated design and construction that exceeds industry standards both functionally and aesthetically.

The following items are described in this OPR:

• Owner Requirements

• Environmental and Sustainability Goals

PLUMBING NARRATIVE

Executive Summary/Overview

Stage 1 Operations Building and Stage 2 Engine Bay will be served by a new 1-/4” domestic cold water service line connected to the existing 2” domestic cold water line that serves the existing Crew

Headquarters Building. The domestic cold water entry assembly will include the building shut-off valve, and an indoor water meter with pulse BAS readout connected to the BAS. Provide a new water meter with BAS readout connected to the BAS for the existing Crew Headquarters building.

Existing Site Conditions

• An existing well with a submersible pump providing potable water to the site.

• There is an existing 2” line from the well to (1) 3,000 gallon above ground storage tank.

There is an existing inline solids separator on the inlet side of the storage tank.

• The outlet of the storage tank routes to the pump house with (1) 1.5 hp pump with the discharge routed to (2) 119 gallon hydro-pneumatic well tanks. The outlet of the well tanks is routed to a sand/solids separator, 1-1/2” water meter and then to the existing building.

• The existing pump operates on a 40/60 psi pressure switch.

• The existing well is assumed to have enough capacity to accommodate the existing building, Operations Building and Engine Bay.

• The total domestic water gpm demand for the existing Crew Headquarters Building is 52 and for the new Operations Building (including the Stage 2 Engine Bay) is 57. Because the total staff population will not increase and will just be divided up between the existing Crew

Headquarters Building and the new Operations Building, the existing well pump shall remain and a “T” be installed off the existing 2” cold water line to serve the new Operations

Building.
