Example Reflection – Visualization

Challenge & Selection     During NIT Project Closeout Items-clearing,  I was transferred to Communications Pipeline  Division to handle the poor TETRA radio service coverage issues (pending SOW) in the Central Processing  Facility (CPF) area.  The challenge is complete the task knowing that photography is strictly prohibited in  the areas of implementation.  As quoted from Ms. Angela Myer’s in Module 1 video “Pictures and images  enable us to not only help people understand what it is we're trying to do, but to help really persuade  them in the worthiness of that particular idea, or the strength of, of that concept.”  Recognizing this  handicap, I relied heavily on the power of Visualization to communicate the full Design and resolution of  the radio coverage issue.  The Design exercise has maximized the use of on-site sketches, as-built  drawings, plant operation diagrams, to include available visual maps and publications.  These visual aides    were proven to be very effective during investigation and discussions of the coverage issue. The same  visualization materials facilitated the effective transfer of ideas during development and execution of the  corrective actions needed to achieve the goal of providing acceptable radio coverage in CPF plant areas,  particularly in the critical buildings and facilities.    Application     The task started with a joint-meeting with CPF plant personnel, local IT Support Group, Navy  Project Management Team (SAPMT) and Contractor/Consultant representatives.  During the meeting, the  Plant personnel identified the outdoor areas and buildings having poor service coverage and marked them  on the Plant Layout Diagram.  Using the same, sketches were also drawn on critical routes during  operations and maintenance.  The Contractor explained that the reduction of tower height .  (Note: The  RIC Communication Tower height was erected at 60 meters but its height later reduced to 47 meters due  to its close proximity to the nearby Khurais Airport runway.) and consequent reduction in transmit  antenna heights of RIC Communication Tower was the major cause of poor coverage in CPF area. This  conclusion was based on comparison between the coverage plots of the original height and the reduced  antenna heights of the RIC (Residential Industrial Complex) Communication tower.  The colored plots have  visually presented the extent of coverage as well as the quality of radio signals, at both heights, reaching  the CPF plant area.  In preparation for the next phase - which is of optimization, the marked buildings and  facilities including routes of interests are identified as coverage Targets. Optimization shall focus on  improving coverage in the Targets’ areas. Using antenna profile drawings, the Contractor described the  remedial actions to optimize the current antenna configuration such as re-alignments, re-directivity and   change of spacing.      Drive test data were collected in the Targets’ areas: before and after optimization. The data collected  were presented to the Plant personnel using printed drive test route maps.  Each data point in the map is  color-coded to represent the radio signal level received at that instant of the route.  Drive testing was  complimented by actual indoor call simulations inside marked Targets to verify the effectiveness of the  antenna optimization techniques applied.  Unfortunately, the optimized antenna configurations failed to  satisfy the Plant personnel’ service coverage requirements.    Consequently, the Contractor recommended the installation of a separate radio system inside the CPF  Plant area.  Using printed Plant Vicinity Plan Layout, the Contractor identified candidate buildings that can  serve the purpose.  Printed plot maps were shared showing the coverage of each candidate.  Existing  buildings were primarily chosen to minimize the tower-structural support requirements.  On-site visits

were conducted using architectural drawings of rooftops for reference.  After careful evaluation, it was  concluded that candidates’ rooftops were not high enough for effective antenna transmission.  In  addition, it was noted that there is no space on the rooftops that can structurally support the erection of  a small tower to meet the needed transmit height.    Finally, agreement was reached to erect a new communication tower beside the CPF Communications  building.  A Task Group was formed for this complicated job since Navy (SA) has no experience in  installing a new tower inside a Processing Facility in operation.  The complexity of this job involves the  methodical underground digging-excavation where complex networks of communication, water-,  electrical power-, upstream/downstream piping-, etc. encounters are most likely to happen.  Through  enough, optical fiber transmission ducts and underground utility systems were discovered during tower  foundation excavation works.  As a result, the tower foundation footings were re aligned accordingly.    The fifty-four (54) meter RIC Communication tower was finally completed construction on November,  2014 and the associated radio system was commissioned on January, 2015.  The transmit antenna,  mounted on top of the tower, have been tested to support the indoor radio service requirements inside  the critical buildings and facilities as well as the outdoor coverage in the CPF plant areas.  Improved  coverage along the security inspections routes beyond Khurais RIC and CPF areas was also attained during  tests.  Further verifications of the enhanced radio service coverage have recommended the elimination  of radio repeaters which were later decommissioned.    Effective Communication and applied Visualization Tools between the CPF Plant personnel, SAPMT, IT  Support Groups and Contractor representatives played a vital role in the successful Designing of Khurais  Radio Service Coverage Improvement.     In conclusion, (with minor changes) from a quote of Ms. Angela Myer’s in Module 1 video “Visualization  played a major role to play throughout the design process or the development process.”
