PART 1 GENERAL

1.1 SUBMITTALS

Government approval is required for submittals with a "G" classification.

Submittals not having a "G" classification are for information only. When used, a code following the "G" classification identifies the office that will review the submittal for the Government. Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES:

SD-01 Preconstruction Submittals

Salvage Plan; G

Documentation Of Utilities; G

1.2 WORK COVERED BY CONTRACT DOCUMENTS

1.2.1 Project Description

The work includes All labor, materials, and equipment necessary to complete the requirements in the contract drawings and specifications to deliver a complete and useable facility for the replacement of an existing

14.5 MG underground water storage tank within its existing footprint. The tank is approximately 612 ft in length and 162 ft in width.

There are 2 one-story historic brick buildings, M-6 McMillan Control House (North) and M-20 McMillan Flume Building, located on the roof of the existing clearwell that will be demolished. Following replacement of the clearwell, these brick buildings will be rebuilt in their current locations to match their historic exterior appearance. Reconstruction will be carried out in accordance with the Secretary of the Interior's Standards for the Treatment of Historic Properties, (36 CFR, Part 68). The North Clearwell Drain Valve Operator mechanism will be salvaged from building M-6, restored and reinstalled in an alternate location outside the building as indicated, along with an interpretive panel to be provided by others.

The work will include temporary relocation of existing utilities on the roof of the clearwell during construction and reinstallation following the replacement of the clearwell. The existing roof is covered with soil and grass, there is an existing access hatch on the west side of the clearwell to allow construction equipment to gain access into the clearwell.

Lateral bracing of the existing walls will be provided from within the tank to support them during installation of the new tank. This lateral bracing of the existing walls along with SOE micropile, columns, struts and whalers will all be a delegated design by the contractor after award.

After installation of lateral bracing the roof, columns, and floor of the clearwell will be demolished. Lateral bracing will remain installed until the new roof and floor have been installed.

The new tank construction will include a new concrete mat foundation, SECTION 01 11 00 Page 1 columns, walls poured against the existing walls, and roof. New concrete baffles will be installed in select areas to direct water from the tank influent to the tank effluent.

The work will include the installation of new influent and effluent concrete chambers, and a new concrete drain chamber, slide gates, and actuators (gate operators). A new process chemical and control system will be installed, and a new waterproofing membrane and landscaped grass roof will be installed over the new concrete roof and incidental related work.

1.2.2 Location

The work is located at the McMillan Water Treatment Plant on 1st Street, NW DC, approximately as indicated.

1.3 EXISTING WORK

In addition to FAR 52.236-9 Protection of Existing Vegetation, Structures, Equipment, Utilities, and Improvements:

a. Remove or alter existing work in such a manner as to prevent injury or damage to any portions of the existing work which remain.

b. Repair or replace portions of existing work which have been altered during construction operations to match existing or adjoining work, as approved by the Contracting Officer. At the completion of operations, existing work must be in a condition equal to or better than that which existed before new work started.

1.4 LOCATION OF UNDERGROUND UTILITIES

Miss utility does not provide utility location services at the site. The locations of utilities on the contract drawings are general and not 100% accurate, and must be verified by the contractor prior to construction.

The location and elevation of utility lines (live and abandoned) within 20ft of proposed construction or utility relocations shall be located by the contractor and shall be positively identified for exact horizontal and vertical locations before construction or utility relocation in these areas. The Documentation of Utilities shall be submitted to the Government in electronic AutoCAD files format for their use, and shall also be incorporated into the as-built drawings for the work.

Coordinate with the Government and provide notification 21 calendar days prior the start of utility location efforts.Obtain digging permits prior to start of excavation, and comply with Installation requirements for locating and marking underground utilities.

Scan the construction site with Ground Penetrating Radar (GPR), electromagnetic, or sonic equipment, and mark the surface of the groundor paved surface where existing underground utilities are discovered. In addition to verifying the elevations of utilities shown on the drawings, v erify the elevations of existing piping, utilities,and any type of underground obstruction not indicated, or specified to be removed, that is indicated or discovered during scanning, in locations to be traversed by piping, ducts, and other work to be conducted or installed. Verify elevations before installing new work closer than nearest manhole or other structure at which an adjustment in grade can be made.

SECTION 01 11 00 Page 2

1.4.1 Notification Prior to Excavation

Notify the Contracting Officer at least 21 calendar days prior to starting excavation work.

1.5 SALVAGE MATERIAL AND EQUIPMENT

Items designated by the Contracting Officer to be salvaged remain the property of the Government. Segregate, itemize, deliver and off-load the salvaged property at the Government designated storage area.

Provide a salvage plan, listing material and equipment to be salvaged, and their storage location, in accordance with section 02 42 91 REMOVAL AND SALVAGE OF HISTORIC CONSTRUCTION MATERIALS and 01 14 00 WORK RESTRICTIONS.

Maintain property control records for material or equipment designated as salvage. Provide a system for property control in the salvage plan.

Store and protect salvaged materials and equipment until disposition by the Contracting Officer.

A badged individual is required on site at all times when work is being performed.

1.3.1.3 No Smoking Policy

Smoking or the use of tobacco products within the clearwell is strictly prohibited.

SECTION 01 14 00 Page 3

Smoking is prohibited within and outside of all buildings on installation, except in designated smoking areas.

Discarding tobacco materials other than into designated tobacco receptacles is considered littering and is subject to fines. The Contracting Officer will identify designated smoking areas.

1.3.1.4 Food and Drink Policy

Eating and drinking is prohibited within the clearwell except for the consumption of plain water.

1.3.2 Working Hours

The existing buildings and their contents must be kept secure at all times. Provide temporary closures as required to maintain security as directed by the Contracting Officer.

1.3.5 Utility Cutovers and Interruptions

a. Make utility cutovers and interruptions after normal working hours or on Saturdays, Sundays, and Government holidays. All outages must be requested no less than 2 weeks in advance.

b. Ensure that new utility lines are complete, except for the connection, before interrupting existing service.

c. Interruption to water, sanitary sewer, storm sewer, telephone service, electric service, air conditioning, heating, fire alarm, compressed air, and water treatment processes are considered utility cutovers.

Such interruptions are further limited to the hours defined for the interruption. This time limit includes time for deactivation and

SECTION 01 14 00 Page 4 reactivation.

d. Operation of Water Treatment Plant Utilities: The Contractor must not operate nor disturb the setting of control devices in the McMillan Water Treatment Plant , including water, sewer, electrical, and steam services.
