Date: .? 1 1 1 1 0 EXHIBIT—B CSU Weather Station Installation PROPOSAL for the City of Fort Collins and Colorado State University Department of Atmospheric Science Background Colorado State University (CSU) has operated a weather station on the campus in Fort Collins for more than 40 years. The City of Fort Collins (City) will begin work on a transportation project in 2003 that will require the existing weather station to be moved to a new location near the old Fort Collins High School. The City is responsible for constructing the new station to the specifications set forth by CSU's Department of Atmospheric Science. DIAD Incorporated has been asked to support the construction and is thus providing a cost estimate to purchase the hardware and to build the new site. Project goals The new station should be installed as soon as possible because environmental data for an overlapping period from both sites is required in order to develop correlations between the two locations. It is anticipated that the original station will be dismantled in August of 2002. The tear -down of the original site is not included in this proposal. The environmental sensors used at the new site should be identical (wherever possible) to the instrumentation used at the original site. The hardware and instrumentation to be established at the new location include: • 10 meter meteorological tower, • RM Young 05103 wind sensor, • Vaisala HMP45C temperature and relative humidity probe with a 12 gill radiation shield, • Vaisala CS105 barometric pressure sensor, 600-1060 mbar, • A soil moisture sensing network that conforms to NRCS standards, • A soil temperature sensing network of twelve Type T thermocouples installed vertically from 4 inches to 10 feet. • Campbell Scientific CR10X data logger • Telecommunications equipment At the request of CSU, an optional 8-inch diameter, 0.01-inch tipping bucket rain gage is also included. The site will consist of a 10-meter meteorological tower set in concrete and enclosed by a four -foot high chain link fence. The distance between the fence and the tower must be at least 6 feet on all sides. DIAD Incorporated 1 2114102 All electronics, the data logger and telecommunications equipment will be housed in a weather resistant enclosure mounted to the tower. Meteorological sensors will be mounted to the tower and soil sensors will be placed in the ground within the fenced area. A Campbell Scientific CRtOX data logger will be used to collect and store data. CSU will monitor instrumentation and transfer data using a cellular digital packet data (CDPD) modem and wireless telephony using Campbell's native communication software (PC208W). Site development includes providing the required software and hardware to enable this link at the new weather station. The installation and configuration of software at CSU's Department of Atmospheric Science is not part of this proposal. Work Plan DIAD is proposing to supply and install the tower, data logger, telecommunications equipment, above ground instrumentation and soil monitoring instrumentation. DIAD will also be responsible to perform trenching, regrading, revegetation and fencing of the site. Scope of work Task 1 - Project management, site visits and site plan DIAD will assign a project manager to oversee the installation and acceptance of the new station. This person will be the primary contact between the City, CSU and DIAD and will coordinate all aspects of the project. The project manager will be responsible for ensuring project schedules and deliverables are met, that the lines of communication stay open and that the project is completed and accepted by the City and CSU. The City will assign a project manager who will be DIAD's primary contact. CSU will assign a project manager to coordinate both the scientific needs and the physical placement requirements of CSU. DIAD will conduct site visits as necessary to discuss the location of the new weather station and placement of weather and soil instrumentation. DIAD will develop a site plan, which will be approved by CSU Facilities, CSU Atmospheric Science Department and the City prior to construction. DIAD's project manager will facilitate this approval. Task 2 - Equipment order DIAD will order all the equipment needed to install the new station. A list of the primary required hardware components is shown in Appendix A. It includes a meteorological tower (Rohn), a weather tight enclosure for the data logger and electronics, a CR10X data logger with multiplexor, a CDPD phone modem, an RM Young wind sensor, Vaisala temperature, relative humidity and barometric pressure sensors, tipping bucket rain gage, soil monitoring sensors, a solar panel, a cellular phone antenna and batteries. The Rohn tower will be painted a flat, neutral color to minimize visual contrast. DIAD Incorporated 2 2J14/02 Note that the purchase of equipment and subsequent installation activities are contingent upon the final specification of the soil moisture array by CSU's Department of Atmospheric Science. Task 3 - Tower installation DIAD will hire an excavation subcontractor to dig the hole into which the tower base will be set. The tower base will be set into a concrete pad that will be adequately plumbed for sensor and electronic cabling. Conduit will be included in the concrete to run future permanent power and telecommunications cabling. The 30-foot tower will be assembled after the base is set. A weather tight enclosure (NEMA Type 4) will be mounted to the tower. The data logger, sensing electronics and telecommunication equipment will be housed inside the enclosure. A solar panel and 12 volt battery will supply power to the data logger and sensors. Task 4 - Data logger programming DIAD will modify the existing weather station program to be compatible with the new sensing and telecommunications equipment. The data logger program will be written with input from Nolan Doesken so that it meets the data collection needs of CSU. The CR1 OX programs will be bench tested by DIAD prior to installation in the field. Task 5 - Weather sensor installation DIAD will install the above ground weather instruments including the wind speed and direction sensor, air temperature sensor, relative humidity sensor and barometric pressure sensor. The wind instruments will be installed at the 10 meter level on the tower while air temperature and relative humidity will be installed on a separate post about five feet from the tower. The CR10X data logger will be installed inside the NEMA enclosure. All sensor inputs, multiplexor and the cell phone modem will be connected to the CR10X data logger. An optional 0.01-inch tipping bucket rain gage can be installed as part of this task. The cost of a rain gage is approximately $800 and includes the tipping bucket with 50 feet of cable and a leveling base. Task 6 - Telecommunications infrastructure Ultimately a telephone line connected to a COM210 modem will be used to communicate information from the CR10X data logger to CSU's Department of Atmospheric Science. It is our understanding that a phone line will not be available at the time of data logger activation, therefore a CDPD cell phone will be used as an interim backup to retrieve data. AT&T Wireless offers a plan for the CDPD option under their wireless data services. The cost of the plan ranges from $8 per month plus $0.06 cents per kilobyte up to $55 per month for unlimited usage. The equipment required includes a CDPD cellular digital modem, a mounting adapter kit, a directional (Magi) antenna and a 9 pin to RS-232 serial interface cable. DIAD Incorporated 3 2114102 CSU and the City will have responsibility to activate the appropriate service plan with the phone company. Note that these costs are not reflected in this proposal. Task 7 - Soil sensor installation All sub terrain instrumentation will be installed at the same time. DIAD will excavate and shore a 12-foot deep trench for the installation of the soil temperature and moisture sensors. The soil temperature probes and the soil moisture array will be installed at predetermined depths in undisturbed soil. Sensor cables will be routed underground through conduit, up through the concrete pad and into the NEMA enclosure to the data logger. The trench will be backfilled and compacted following the installation of the soil monitoring sensors. DIAD will remove any remaining fill and regrade the site to its pre - disturbed condition. Task 8 - Site fencing Site fencing will not take place until the soil monitoring network is installed. DIAD will install a 4-foot high chain link fence around the site. The fence will include 164 lineal feet of fencing and will have a 3-foot wide gate at one end of the enclosure. The gate will have the capability to be locked using a standard padlock. Task 9 - Site revegetation Site revegetation will not take place until the fence is installed. DIAD will plant dry land grass seed in the disturbed area of the site. Since the site does not have water currently available and cannot be watered because of the impact on the sensors, DIAD can not be responsible for ensuring that the grass seed takes root. Task 10 - Final documentation DIAD will provide the City and CSU with a report that summarizes the installation activities. The report will include an electronic and hardcopy output of the data logger program, instruction manuals for the installed sensors, general installation techniques, and location diagrams of underground components and cabling.

Note that equipment purchase and installation activities are contingent upon the final specification of the soil moisture array by CSU's Department of Atmospheric Science. The delay of these specifications may result in a project change order to address modifications to schedule and cost. DIAD will make every effort to expedite the installation of the new weather station. We will begin work and order equipment as soon as a contract is signed or written notice to proceed is issued from the City. The installation will proceed within the constraints of several factors including the delivery of hardware, the weather and the coordination of the proposed work with existing DIAD installation obligations that begin in March. The expedited delivery of the Rohn Tower and hardware from Campbell Scientific could take between 3 and 4 weeks. We will work as quickly as possible to get the hardware installed once it arrives. General Contract Terms DIAD's existing task order contract with the City will be used to complete this project.
