STATEMENT OF WORK

Replace Pumps and Reconfigure Valves

UHHZ 060005

Revised: 30 April 2009 20 January 2009

Revisions and Amendments:

30 April 2009:

1. Concern: Due to the heavy materials contained in the sludge that is pushed through the existing piping and equipment, I was thinking that all demoed pipe and equipment would have to be triple rinsed before it could be recycled or disposed of. Is there any requirement or concern for possible hazardous materials? Should we add cost for handling this?

Response: Robins AFB adds no requirement to existing regulation. The pipes may be triple washed and recycled. Refer to spec 02050 Demolition and Removal sections 1.3.1.4, Tank and Piping Removal and Disposal Plan, and 1.3.1.5, Qualifications (Contractor Experience).

2. Concern: The SOW does not ask for the PLC to be replaced with a color monitor. Is the existing display board sufficient?

Response: The existing equipment shall remain in place. No upgrades to the monitor shall be made.

3. Concern: Item 2.9 of the Statement of Work dated 20 Jan 09 states “The existing PLC hardware shall be reprogrammed to operate similarly to the JWI filter press PLC and operate in RS Logic 500”. The existing hardware cannot be reprogrammed to meet those specs. We will need to rewrite the entire program; is that the intent of this statement?

Response: The scope of this project is to provide the facility with the use of the filter press in question. The contractor shall take all steps necessary for full completion of the project and operation of this press and rewrite the program as necessary.

Section 2.9 of this Statement of Work has been revised.

4. Concern: I do not see any LD’s mentioned. Will this apply and what would the daily amount be?

Response: Liquidated Damages are required for this contract. Please refer to the form that has been added to the solicitation.

5. Concern: Will it be possible to get existing or asbuilt drawings of the PLC control system?

Response: No asbuilt drawings or wiring diagrams of the existing PLC control system are available but will be required of the Contractor for the new system.

Please refer to section 2.9 of this statement of work.

6. Concern: Will it be possible to get a PLC logic diagram of the new controls to ensure total compliance on the program side from the equipment manufacturer or the base engineer?

Response: Refer to section 2.9 of this Statement of Work for contractor responsibilities. All work done on previous systems is copyrighted and will not be made available.

1. SCOPE OF WORK:

The objective of this project is to replace the sludge pumps, piping, valves, and other associated equipment that conveys sludge to the IMCO Filter Press in Building 352. The contractor shall provide all labor, materials, coordination, and supervision to remove all old equipment and install new pneumatic pumps, electronic actuators, pipes, and other supporting materials.

1.1 Period of Performance: 120 days

2. SPECIFIC TASKS:

2.1 Demolish the existing:

2.1.1 (2) 6”x6”x6” Tees on the influent line

2.1.2 Approximately 20’ of 6” steel pipes and pipe supports

2.1.3 (2) Screw pump and pump base mounts

2.1.4 (2) 6” to 4” reducers

2.1.5 (2) Sludge blow-off assembly with supports

2.1.6 (2) Pressure gauges

2.1.7 (2) 4” Butterfly Valves

2.1.8 (2) ¾” Sludge pressure relief return lines that run from the 6” lines connecting to the pump inlets on either side to the 4” pipe located just after the sludge blow-off assemblies.

2.1.9 Approximately 21’ of 6” steel pipes and fittings

2.2 Demo the return sludge line from fittings that connect it to the return effluent line to the tie in location on the 6” line influent line near the 6” valves. Place inline flanges on remaining ends as not to disturb flow or allow any flow to escape the system.

2.3 Demo three (3) designated pneumatic actuators that are located on the wall outside of the press room. All air lines will be removed and the remaining three (3) pneumatic actuators will be removed as they will be replaced with full electronic actuators. All wires and conduit, both air and power, not associated with the new actuators shall be removed. After removing the actuator on the pre-coat line, place inline flanges on either end on the exposed pipe in order to keep the sludge from the pipe feeding the press from escaping the system and properly seal the unused pipe.

2.4 The 2” galvanized waterline shall be removed along with the actuator and any wires or conduit that connect this actuator to the existing air or power supply.

2.5 Inside the room containing the filter press, the contractor shall remove the 3” pipe connecting the pre-coat tank to the press and any actuators, gauges, or drains on that line and place an inline flange on the opened pipe to contain its contents. All pneumatic actuators and wires or conduits pertaining to those actuators shall be demolished and replaced by electric actuators will all necessary fittings for full operation.

2.6 Installation of new materials:

2.6.1 6”x6”x3” Tee to reconnect the 6” line to the transfer pumps and allow a 3” discharge to run perpendicular to the line and parallel to the ground.

2.6.2 Install the Warren Rupp pump model S30 Filter Press skid containing both high and low pressure pneumatic pumps shown in drawing number 450.424.000 or skid containing pumps equivalent to the EH2-M high pressure and the S30 Metallic low pressure Warren Rupp brand pumps. All specifications must be the same.

2.6.3 A water tap shall be installed on the line prior to reaching the pump skid for flushing purposes. A tap shall also be placed on the existing water line along the wall so that line may be used as a water source for flushing the line.

2.6.4 Install all piping, fittings and gaskets, pipe supports, electronic actuators, and various valves necessary for the filter press to mimic the operation of existing presses in the plant.

2.6.5 The installed parts shall be constructed of the same or similar grade material as the original parts.

2.6.6 Once the installation of all components is complete, the system shall be tested for proper operation.

2.7 Clean, prepare, and paint all piping in the work area.

2.8 The existing dyke shall be demolished 12’ from the northern wall all the way past the 90° bend to the western wall. A new dyke shall form a 90° angle with the remaining dyke an run until it makes contact with the western wall effectively reducing the existing dyke by half of its original area.

2.9 The existing PLC hardware shall be reprogrammed to operate similarly to the JWI filter press PLC and operate in RS Logic 500. The program will have to be rewritten to achieve this objective. No asbuilt drawings of the existing system are available. Please provide 2 digital and 2 hard copies of the PLC Program with text file and 2 days of onsite operator training
