The Walton Mountain Site is located at 40° 21’ 15.9”, -106° 41’ 58.5” in Routt County, Colorado. The building shall have a finished floor that is nominally 12’ above existing grade. The shelter is to be used to house electronic communications equipment. All bidders have attended the mandatory pre-bid site walk and should be familiar with the site constraints. The selected bidder will be responsible for all means and methods to provide the State with a shelter that meets the requirements of this RFP. The State anticipates that the selected bidder will utilize a helicopter to transport materials to the site due to the difficulty of transporting materials on the access road. 4 2 GENERAL BID SPECIFICATIONS 2.1 The terms “The State” and/or “Purchaser” in this Request for Proposal (RFP) refer to the State of Colorado, Office of Information Technology. “Bidder” refers to the organization submitting proposals in response to these specifications. “Vendor” refers to the successful Bidder after award and execution of the Contract between the State and the Bidder. 2.2 The Vendor shall design, furnish and install a fully constructed shelter, support structure and ancillary equipment as described in this RFP. 2.3 The Vendor shall begin designing the shelter, support structure and ancillary equipment immediately after the project is awarded. Construction is anticipated to begin when the snow clears from the site for the season, approximately the end of May 2014. The State reserves up to five (5) business days to review each submittal as required by this RFP. Construction of the project shall be completed by August 31, 2014; all closeout documentation shall be completed by September 30, 2014. 2.4 These specifications do not include any proprietary items, which would preclude any equipment manufacturer from producing equipment to meet these specifications with the exception of the equipment in section 6.5.6.6. All mechanical ratings or any technically specified criteria contained within these specifications are currently being met by commercially available equipment. The fact that a manufacturer chooses not to produce equipment to meet these specifications, providing the above criteria are met, shall not be considered sufficient cause to adjudge these specifications as restrictive. Should any of the above criteria not be met within these specifications as to cause a portion of these specifications to be proprietary, The State should be advised immediately. 2.5 Jobsite safety and worker safety is the responsibility of the Vendor. 2.6 The Vendor shall not procure any materials, construct or remove any structure, or perform any design services prior to receiving a Notice to Proceed from the State. Any work or materials performed or acquired by the Vendor without a written Notice to Proceed from the State are done so at the Vendor’s risk and may not be eligible for compensation by the State. 2.7 The Vendor shall be responsible for the cost of labor and expenses incurred by the State and its consultants for any site visit that must be repeated due to the fact that the Vendor was not prepared for the site visit after scheduling the visit or Vendor failed to meet the requirements of the project Specifications, therefore requiring a repeat site visit, unless this fact was previously documented in writing prior to the site visit by the State. Costs will be based on reasonable rates. 2.8 The Vendor shall not leave hazardous materials, including fuels, oils, and lubricants unattended at the site at any time. Hazardous materials shall be removed from the site at the end of each workday or temporarily stored inside a locked and posted building until the following workday. Construction materials and supplies other than hazardous materials may be left unattended at the construction site at the end of each workday at the Vendor’s risk. 2.9 The State will entertain alternate proposals from the selected Vendor, but the bidder must provide a price for the scope of work as designed in this solicitation. 5 2.10 Colorado labor shall be employed to perform the work to the extent of not less than eighty percent (80%) of each type or class of labor in the several classifications of skilled and common labor employed on the Project. If the Federal Davis-Bacon Act shall be applicable to the Project, as indicated in Article 7B (Contractor’s Agreement 6.21), Modification of Article 27, the minimum wage rates to be paid on the Project will be specified in the Contract Documents. If a modular building is proposed as part of the bid it is considered materials and the 80% labor requirement does not apply. 6 3 WARRANTY AND CONDITIONS 3.1 Building as installed per these specifications shall be fully warranted by the Vendor against any mechanical or engineering defect for a period of at least 5 years from the date of installation.

It is imperative that communication downtime is minimized during the transition from the old shelter to the new shelter. To aid this transition, the State plans to run new feedlines from the rack location inside the new shelter to the existing antennae on the tower. The cutover will consist of moving the radios from the existing building to the new building, attaching the previously installed feedlines to the existing radios while concurrently exchanging the feedlines on the antenna from the old to the new. All necessary materials including, but not limited to, coax, connectors and mounting kits, will be provided by the State. Additive Alternate Number 1is to: Install new State provided feedlines, necessary hardware and connectors for all equipment listed in Table 2; Move radios from old building to new; Connect existing radios and antennae to new feedlines. Additive Alternate Number 1 will be complete when the radios, feedlines, and connectors are installed per the referenced standards and the system is operating properly.

To aid this transition, the State intends to perform a system cut over per the following: The microwave paths at this site are space diversity microwave paths with A and B transmitters; The A receiver operates on the top antenna while the B receiver operates on the lower antenna. To achieve the shortest possible downtime the state is proposing to turn off the radio B side receiver; Remove the B side antenna and replace with new like antenna (Table 3) and install new waveguide into new building and align the path with the spectrum analyzer; Shut down radio and remove from old building and install into new building hooking up the newly run waveguide to the A port leaving the B receiver off; Turn up radio and check operation. If operation is acceptable proceed with the following: Replace the existing A side antenna and waveguide installing new antenna and running new waveguide into new building and align the path with the spectrum analyzer; Shutdown radio remove newly attached waveguide on A port and move to B port and then attach the waveguide from the A antenna to the A port. Power up radio. This procedure is to be followed for each space diversity radio. All necessary materials including, but not limited to, coax, connectors and mounting kits, will be provided by the State. The old microwave dishes will remain the property of the State. The dishes shall be removed from the tower, placed in a location directed by the State and be in working condition. Additive Alternate Number 2 is to complete the work stated above will be complete when the radios, waveguide, and connectors are installed per the referenced standards and the system is operating properly.
