Construct Ambulance Garage

Vision Statement

Provide a climate controlled two-bay garage with storage for parking two ambulances.

C.1. Introduction

C.1.1. Project Title

Construct Ambulance Garage.

C.1.2. Background

Because there are no current cost-effective alternatives for housing the EMTs and storage of the ambulances, it is necessary to construct an ambulance garage adjacent to the existing EMT facility, Bldg. 5454, to store the ambulances indoors. This will allow certain medical supplies to be stored within the ambulances, eliminate the need to leave vehicles running during hot and cold weather, reduce the risk of employee injury during cold, icy weather, and reduce the EMT response time for emergencies.

C.1.3. Summary of Work

C.1.3.1. Work will be performed at USAG Dugway Proving Ground (DPG), approximately as indicated. The exact location will be shown by the Contracting Officer (KO) or their designated representative.

C.1.3.2. Construct a two-bay, climate controlled ambulance garage adjacent to Bldg. 5454.

C.2. General Requirements

This section describes the general requirements for this effort. The following sub-sections provide details of various considerations on this effort.

C.2.1. Non-Personal Services

The Government shall neither supervise contractor employees nor control the method by which the contractor performs the required tasks. Under no circumstances shall the Government assign tasks to, or prepare work schedules for, individual contractor employees. It is the responsibility of the contractor to manage contractor and subcontractor employees and to guard against any actions that are of the nature of personal services, or give the perception of personal services. If the contractor believes that any actions constitute, or are perceived to constitute personal services, the contractor is to immediately notify the KO.

C.2.2. Project Management & Coordination

Positively identify all underground utilities work in the area IAW the excavation permit and approval letter and coordinate with all parties mentioned therein. The Contractor is responsible for maintaining all markings made during the utility investigation throughout the

Period of Performance (PoP).

C.2.10.2. Physically verify underground utility locations by hand digging using wood or fiberglass handled tools when any adjacent construction work is expected to come within three feet of the underground system. Use mechanical equipment when digging within 24 inches of a known utility is not permitted. If excavation is parallel within 60 inches to an existing utility, expose the utility by hand digging every 100 feet.

C.2.14.3.2. Record Drawings: The terms "drawings," "contract drawings," "drawing files,"

"working record drawings" and "final record drawings" refer to contract drawings which are revised to be used for final record drawings showing as-built conditions.

C.2.14.3.2.1. Revise 2 sets of paper drawings by red-line process to show the as-built conditions throughout the progress of the project. Keep these working as-built marked drawings current on a weekly basis and at least one set available on the jobsite at all times. Accurately and neatly record changes from the contract plans which are made in the work or additional information which might be uncovered in the course of construction as they occur by means of details and notes. Prepare final record (as-built) drawings after the completion of each definable feature of work as listed in the Contractor Quality Control (CQC) Plan (Foundations, Utilities, Structural Steel, etc., as appropriate for the project).

C.2.14.3.2.2. Information shown on the working and final record drawings shall include, but is not be limited to, the following:

In order that the location of these lines and appurtenances may be determined in the event the surface openings or indicators become covered over or obscured, show by offset dimensions to two permanently fixed surface features the end of each run including each change in direction on the record drawings. Locate valves, splice boxes and similar appurtenances by dimensioning along the utility run from a reference point. Also record the average depth below the surface of each run.

2) The location and dimensions of any changes within the building structure.

3) Correct grade, elevations, cross section, or alignment of roads, earthwork, structures or utilities if any changes were made from contract plans.

4) Changes in details of design or additional information obtained from working drawings specified to be prepared and/or furnished by the Contractor; including but not limited to fabrication, erection, installation plans and placing details, pipe sizes, insulation material, dimensions of equipment foundations, etc.

5) The topography, invert elevations and grades of drainage installed or affected as part of the project construction.

6) Changes or modifications which result from the final inspection.

7) Where contract drawings or specifications present options, show only the option selected for construction on the final as-built prints.

8) Systems designed or enhanced by the Contractor, such as HVAC controls, fire alarm, fire sprinkler, and irrigation systems.

C.2.14.3.2.3. Modify the record drawings as may be necessary to correctly show the features of the project as it has been constructed by bringing the contract set into agreement with approved working as-built prints, and adding such additional drawings as may be necessary.

These drawings are part of the permanent records of the project and will be returned to the Contracting Officer after approval by the Government.

C.2.14.3.2.4. Provide electronic copies of the record drawings in both PDF and AutoCAD 2010 compatible format. Only employ personnel proficient in the preparation of CADD drawings to modify the contract drawings or prepare additional new drawings. Additions and corrections to the contract drawings will be equal in quality and detail to that of the originals. Line colors, line weights, lettering, layering conventions, and symbols will be the same as the original line colors, line weights, lettering, layering conventions, and symbols. If additional drawings are required, prepare them using the specified electronic file format. The title block and drawing border to be used for any new final record drawings will be identical to that used on the contract drawings.

Accomplish additions and corrections to the contract drawings using CADD files. The Contractor will be furnished "as-designed" drawings in AutoCAD 2010 format. The electronic files will be supplied on compact or DVD disc. Provide all program files and hardware necessary to prepare final record drawings.

C.2.14.3.2.5. Color code changes as follows:

1) Deletions (Red) - Over-strike deleted graphic items (lines), lettering in notes and leaders.

2) Additions (Green) - Added items, lettering in notes and leaders.
