SF30 Block 14 Description of Amendment

Notice ID: 15B61026Q00000002 Project Title: MCC San Diego - Replace Water Distribution Pump - Project 26Z6AK7 Location: MCC San Diego, 808 Union Street, San Diego, 92101

A. SOLICITATION QUESTIONS AND ANSWERS

The purpose of this amendment (0002) is to provide responses to vendor technical questions submitted to Solicitation # 15B61026Q00000002.

Q1. Isolation Valve Quantity - The SOW states that (2) new 4-inch isolation valves are to be installed. Field verification confirms (4) existing 4-inch isolation valves are currently in place. Please confirm whether all (4) valves are to be replaced, or only (2), and if only (2), identify which valves are included in the scope.

A1. Only 2 valves need to be replaced along with 1 check valve. Pump make and model shall be Grundfos, Hydro MPC-E 3CRE, 45-3-2, 3X460V - OR EQUIVALENT. Attached is the pump spec sheet.

Q2. Provide the clear car dimensions, door opening dimensions, and load capacity of the freight elevator serving the basement. This information is required to confirm that the new pumps, valves, and associated materials can be delivered to the work area via the elevator, or whether alternate rigging and access provisions will be required.

A2. Elevator Door:

Width 47 3/4 in

Height 83 3/4 in

Elevator Platform:

Length 78 in Width 48 in Height 83 3/4in

Max Cap 3000 LBS

Q3. Confirm that demolition is limited to the suction and discharge piping between each respective set of isolation valves, with existing piping outside those limits to remain in place. If demolition is to extend beyond the isolation valves, please identify the intended termination points.

15B61026Q00000002 / 00002 Page 3 of 3

A3. All piping from building down to the isolation valves will remain. All piping after isolation valves will need to be replaced.

Q4. Provide the exact model of the Hydro Multi-E 3 pump system required by the

Government, including the full model designation and configuration (individual pump model and size, horsepower, voltage and phase, design flow and head, manifold and connection sizes, and control/enclosure requirements). This is required to confirm the correct unit at submittal and verify fit within the existing footprint and connection points. If an approved equal will be accepted, please confirm.

A4. Pump make and model shall be Grundfos, Hydro MPC-E 3CRE, 45-3-2, 3X460V - OR

EQUIVALENT. Attached is the pump spec sheet.

Qty. Description

1 Hydro MPC-E 3 CRE 45-3-2

Note! Product picture may differ from actual product

Product No.: 99689041

Pressure booster system supplied as a compact packaged assembly certified and listed by UL (Category QCZJ – Packaged Pumping Systems) for conformance to US and Canadian standards.

Approvals:

NSF61/NSF372 – Drinking Water and Low Lead approval. OSHPD Seismic certification available on MPC E CR(CUE) systems.

All pumps are variable-speed pumps.

Each pump is equipped with an integrated variable-frequency drive motor (MLE motor).

- Hydro MPC-E maintains constant pressure through continuous speed adjustment of the pumps.

- The system performance is adjusted to the demand by starting and stopping the required number of pumps and through parallel control of the pumps in operation.

- Pump changeover is automatic and depends on load, operating hours and fault.

- All pumps in operation will run at equal speed.

The system consists of these parts:

- vertical multistage centrifugal pumps, type CRE 45-3-2

- rotating pump parts in contact with the pumped liquid are made of ANSI 304 stainless steel as standard and available as ANSI 316 stainless steel as an option.

Pump bases and pump heads are made of cast iron (Class 30) as standard and ANSI 316 stainless steel as an option.

The pumps are equipped with the service-friendly cartridge-type mechanical-shaft seal HQQE (SiC/SiC/EPDM).

- Inlet and outlet manifolds are made of 316 stainless steel.

- Base frame is made of 304 stainless steel.

- One non-return valve (check valve) and two isolating valves for each pump.

- Adapter with isolating valve for connection of diaphragm tank.

- Pressure gauge and pressure transducer on each inlet and outlet manifold.

Dry-running protection is standard with use of pressure transducer on inlet manifold.

- Steel operating panel with UL Type 3R (MPC E CRE) or Type 12 MPC E CR(CUE) enclosure rating, including main disconnect switch, all required fuses, motor protection, switching equipment and microprocessor-controlled CU 352.

Diaphragm tank is available as an accessory.

Pump operation is controlled by CU352 controller, specifically designed to control parallel operation of multiple pumps with the following features and functions:

- PID controller with adjustable PI parameters (Kp + Ti)

Qty. Description

1 - constant pressure at setpoint, independent of inlet pressure

- stop function (no flow shutdown)

- automatic cascade control of pumps for optimum efficiency

- selection of min. time between start and stop, automatic pump changeover and pump priority

- automatic pump test function to prevent idle pumps from seizing

- standby pump allocation capability

- redundant primary sensor capability

- manual operation

- proportional pressure control

- multisensor zone control with up to six zones

- differential pressure and temperature control using two separate sensors (that is outlet-inlet subtraction)

- secondary fallback sensor will revert to secondary (local) sensor upon primary (remote) sensor failure

- digital pulse water meter reading (log accumulated flow)

- forced pump changeover

- clock program

- soft pressure build-up

- external setpoint influence (via analogue input)

- emergency run (via digital input)

- password protection

- possibility of digital remote-control functions (via digital inputs):

- system on and off

- max., min. or user-defined duty range

- up to 6 alternative setpoints

- digital inputs and outputs can be configured individually.

Pump and system monitoring functions:

- minimum and maximum limits of measured values (flow, level, temp., etc.)

- built-in data-logging capability

- non-return valve (check valve) failure detection

- high system pressure protection

- low system pressure protection

- pump curve data loaded into controller to provide end-of-curve protection

- alarm log with the previous 24 warnings and alarms

- potential-free changeover switches for operation and fault
