C.1.2 Project Description

C.1.2.1 Contractor must provide complete design and construction services and contract coordination and supervision, including but not limited to the management, professional design services, and construction necessary to meet the requirements of this contract within the established schedules.

C.1.2.2 Contractor must design and construct this project in accordance with the technical requirements identified and referenced herein.

C.1.2.3 Site Description

C.1.2.3.1 The U.S. Embassy in Juba is composed of two major site areas; the Office Compound (OC) and the Residential Compound (RC). The Compound Electrical Upgrade project involves electrical work at both embassy sites. The OC is located approximately .365 km west of RC. There are other ancillary areas such as the RC Annex, located across the street from the RC. All areas are located within the city limits of Juba.

C.1.2.3.2 The OC is a rectangular shaped site of approximately 1 hectare (2 acres). It is located on Kololo Road, north of the European Union Embassy. The main vehicle and pedestrian access to the OC are through a Compound Access Control (CAC) facility from a paved frontage road on the east, known as the “East CAC.” A separate vehicle service CAC connects to a dirt road to the west, known as “West CAC.” The OC has a number of mixed uses, including a USAID program office, Embassy functions and consular services. A number of support buildings occupy the OC, including an on-site cafeteria, vehicle maintenance shop, motor pool displace office, workshops and storage.

C.1.2.3.3 The RC is a polygonal shaped site of approximately 2.8 hectares (7 acres). Adjacent, and east of the RC, is the former Regional African Issue (RAI) compound, which abuts the RC east perimeter wall. Both the RC and RAI compounds are enclosed with opaque walls. The RAI compound topography is low-lying and prone to flooding being within a storm-water collection area. Access to the RC is provided via two CAC facilities, each on the west frontage road, one being close to the center of the west perimeter wall known as the “North CAC”, and the second being close to the southwest corner of the compound and known as the “South CAC”. A network of circulation roads within the RC provides access to mission housing. The RC contains housing structures provided in various forms including five ‘single family’ villas, and 28 efficiency residences. An on-site cafeteria provides catering for mission staff and a recreation building and swimming pool is centrally located on the compound.

C.1.2.4 Major Project Elements included in this contract.

C.5.1.7 Electrical Report

C.5.1.7.1 All Buildings (Additional Requirements)

1. Power Quality Study: The Contractor must monitor the utility electrical feeder to collect one week’s worth of power quality data using an energy monitoring device equivalent to a Power Sight PS3000 energy monitor. Obtain the energy-monitoring device for use in the study. If the utility feeder is not available, monitor the utility service at the existing embassy. If this is not practical, monitor a representative commercial building in the area of the site. Recorded data must include a continuous record of voltage magnitude on phases to neutral to determine extent of steady state variation of voltage magnitude and frequency and to create a record of outages during this period. A second similar energy-monitoring device must be used during this period to record the magnitude and duration of transient voltage spikes on one phase continuously. Record the worst spike observed by the energy monitoring device on a daily basis. Based on data gathered, provide a recommendation as to power quality mitigation measures to be employed for the facilities (e.g., voltage regulators, transient voltage surge suppressors).

2. Power Quality/Generators: The Contractor must provide a life cycle cost justification for equipment selection.

3. Design Calculations: The Contractor must perform a complete fault analysis to determine the fault level at transformers, feeder breakers and panelboards. This must be the basis for equipment selection and coordination of the tripping circuits of the protective devices.

Include motor contribution where appropriate. Since the USG has little control of the local utility system with regard to future expansion, the calculation must be based on an "infinite" source at the point of connection. If the initial calculation produces awkwardly high fault levels anywhere in the system that leads to expensive equipment, they must be reduced (in the following order) by using an actual source fault level at the utility connection rather than assuming an infinite source. This value must be obtained from the utility during the pre-design survey; Specifying higher-than-standard transformer impedances to reduce the fault current levels; using current-limiting fuses; or rearranging the distribution system to make use of smaller transformers and to increase system impedance (reduce available fault currents).

4. The Contractor must perform other studies/calculations that are required to insure satisfactory design including 1) voltage drop calculations on the longest and the smallest sized feeders that would provide for the largest potential voltage drop in the system; 2) load calculations that confirm the adequacy of the feeders and circuits and confirm the proper sizes of the switchboards, panels, and protective devices; 3) power factor studies to increase system capacity and provide for economic operation of the electrical system; 4) voltage transient studies to verify the proper operation of the electrical system; and a 5) short circuit and coordination study.

5. Engine Generator Sets: The Contractor must submit generator sizing calculations.

Submit a list of loads that must be connected to the generator and generator sizing calculations including compliance with the more stringent of OBO or local noise and air pollution standards.

6. Equipment Sizing: The Contractor must submit calculations to justify sizing of major equipment such as switchgear, main circuit breakers, and power factor correction equipment.

C.6 COMPLETION

Substantial Completion

"Substantial Completion" means the stage in the progress of the work as determined and certified by the CO in writing to the Contractor, on which the work (or a portion designated by USAID) is sufficiently complete and satisfactory. The activities that are required to be complete to achieve Substantial Completion are provided below:

● Completion of the elements of work as defined in the final design.

● Completion of all Division 01 requirements, including commissioning.

● Submission of final certified site surveys; test pit data and other field investigation data undertaken during the performance of the work.

● Submission of owner’s O&M manuals and warranties for gate motors

● Submission of as-built drawings for all construction.

Substantial completion means that the work is essentially complete and may be used for the purpose for which it is intended, and only minor items such as touch-up, adjustments, and minor replacements or installations remain to be completed or corrected which do not interfere with the intended utilization of the work and can be completed or corrected within the time period required for final acceptance.

The "date of substantial completion" means the date determined by the CO as of which substantial completion of the work has been achieved.

The Government shall have the right to take possession of and use the work upon substantial completion. Upon notice by the Contractor that the work is substantially complete (a Request for Substantial Completion) and an inspection by the Contracting Officer or an authorized Government representative (including any required tests), the Contracting Officer shall furnish the Contractor a Certificate of Substantial Completion, accompanied by the Schedule of Defects listing items of work remaining to be performed, completed or corrected before final completion and acceptance. Failure of the Contracting Officer to list any item of work shall not relieve the Contractor of responsibility for complying with the terms of the contract. The Government's possession or use upon substantial completion shall not be deemed an acceptance of any work under the contract.

Demobilization

At the direction of the CO, after substantial completion inspection the Contractor may be authorized to demobilize all equipment, personnel, materials and temporary facilities from the site according to the approved demobilization plan if there are no significant issues identified during the inspection. If the Contractor is not authorized to demobilize after the substantial completion inspection, the Contractor must not demobilize until after final acceptance.

Final Completion and Acceptance
