4.0 STATEMENT OF WORK (SOW)

This document provides guidelines on the refurbishment process of the IRM office space

(154m²) located in Building#2, level 2. The improvements are required to accommodate the furniture layout shown in figure 2 (rOBO office will supply the new office furniture requested and approved by the head of the IRM section in Sao Paulo, Brazil). The current office furniture layout seats eight (8) IRM employees. The proposed office furniture layout will seat thirteen (13) local IRM staff (an increment of five additional employees).

Office space 2275 (Server room) will be reduced in size (from 34.76m² to 15.48m²) to accommodate room 2275 (Server room, 15.48m²) and room 2274 (19.28m²) in the same space.

Offices 2274 and 2275 will be divided by a non-loadbearing GWB wall (L1) with acoustic treatment and double gypsum board panels (double layer panels) placed on both sides of the wall to reduce vibration and noise levels (see wall L1 in figure 5). Office space 2273 (31.70m²) will remain with the same size but a different furniture layout to accommodate three additional workstations. Offices 2277 (13.34m²), 2278 (25.00m²), and 2279 (18.90m²) will remain with the same size and a small modification involving the office furniture layout in room 2279 (see figure

2). Light fixtures, power outlets, light switches, and computer drops shall be upgraded within the refurbished area as per guidelines covered in sections 4.5 (Electrical) and 4.6 (Telephone &

Computer Drops) to serve the new workstation furniture floor plan. Wall, ceiling, and window demolition required for room 2274 is covered in section 4.1 (Demolition). Dividing walls (GWB

L1 and L2 wall) separating rooms 2275, 2274, and 2273 (GWB L3 wall) is covered in section

4.2 (non-loadbearing walls).

Figure 2 – Architectural layout IRM office space (current vs. proposed).

This project also covers the replacement of floor and ceiling tiles within the IRM refurbished area (section 4.8 - Ceiling Tiles and section 4.10 – Floor Tiles). Upgrades of the existing HVAC system (rooms 2275) is covered in section 4.7 (HVAC). Further instructions on the IRM wall treatment and painting guidelines are covered in section 4.12 (Wall Paint).

Companies interested in the bidding process must check and confirm, during the site visit, if the measurements described in the SOW (figure 3) match the measurements computed in the job site. The information provided in the SOW (drawings and sketches) does not necessarily reflect the most updated as-built version of the job site conditions. Offerors may find small discrepancies between the information provided in this document and the existing infrastructure available in the IRM suite. Companies interested in the bidding process are responsible to verify, get familiar with, and confirm measurements, dimensions, and utilities running within the refurbished area prior from submitting the proposal.

It is also recommended the companies to attend the site visit and a conduct a preliminary site survey and site inspection in the refurbished area. The site survey will help the offerors to get familiar with the construction site and identify complexities, obstructions, or interferences that may affect the logistic of the job or cost of the project. The bidding companies should also identify and get familiar with the existing infrastructure fixed, hanging, running, or concealed inside the walls and ceiling (electrical conduits, air ducts, sprinkler heads, cable trays, smoke detectors, strobe/emergency lights, light fixtures, light switches, power outlets, electrical wires, dampers, announcers, cable trays, sensors, etc.). Companies will not be able to ask for additional funds or file a claim later during construction arguing ignorance, lack of knowledge, or insufficiency of information on the existing site conditions and on the utilities infrastructure.

That sord of a claim will be denied and ignored.

Figure 3 – Office dimensions in SQM (m²) – proposed floor plan.

Cost to replace, repair, demolish, remove, treat, sand, render, paint, move, and install items not covered in the SOW but verbally discussed and agreed upon during the site visit among the site visitors and the USCG will be confirmed on written after the site visit is over. The same guidelines apply to inquiries submitted, on written, by the due date and answered by the USCG via e-mail to all bidders. Items confirmed on written by the USCG will be considered part of the

SOW. It is the contractor’s duty to implement it in the job site and additional costs shall be addressed in the bid proposal.

Contractor will be responsible (and therefore should incorporate expenses related to labor costs) for assembling, disassembling, and transporting to designated areas, office furniture and equipment standing or stored within the refurbished area (tables, chairs, bookshelves, sofas, appliances, cabinets, printers, scanners, lamps, computers, files, boxes, dolly carts, etc.).

Samples of materials requested in the SOW must be submitted to the USCG with the technical specification or data sheet before the contractor procures or install any material or equipment in the job site. Contractor (offerors) shall proceed with the acquisition process only after review and approval from the USCG (CO or COR written approval).
