CSIE has successfully completed over 250 data center/infrastructure projects, ranging from technology infrastructure requirement analysis to the design/build of technology facilities for multi-phase, and multi-year projects.

Due to the confidential nature of most of our government projects, majority of the case studies described are for commercial projects. The projects have been arranged in our service categories.

WMATA TIA

Overview

CSIE’s Electrical and Mechanical engineers and team leaders worked with GFP to advance WMATA’s Transit Asset Inventory and Condition Assessment Project (“TAICA”).  Phase I of the project consisted of producing an   initial   capital   asset   inventory and condition assessment to support the update WMATA’s Capital Needs Inventory (CNI) by the end of calendar year 2016.

Capital needs for the assets include in the assessment were determines over the ten-year period from 2016 to 2026 by determining each asset’s typical service life and year installed. GFP Team’s Subject Matter Experts (SMEs) in conjunction with WMATA’s SMEs established an expected typical service life for each asset type in years. A calculated “Next Renewal Year” was determined by adding the typical service life to the year installed subtracted by the current year. However, the calculated Next Renewal Year could be overridden by the assessor if they felt that the value calculated is not representative of the actual condition of the assets. The Remaining Service Life (RSL) was computed either from the Calculated Next Renewal Year resulted in 2016 or earlier, a “Deficiency” for that asset  was created,   which   could   also   be   thought   of   as   the   asset’s   backlog   of   capital needs. CSIE’s engineers completed surveys and assessments of over fifty stations, maintenance facilities, rail complexes and yards, and bus facilities.

Project Highlights:

Location: Various stations throughout the Metro System
Size: Varied by location

Key Project Elements

  • CSIE provided engineering services under the direction of the Gannett Fleming Parsons (GFP) Joint Venture as part of their GAEC Facilities contract
  • According to directions received from WMATA, the condition assessments were performed using a rating scale consistent with the FTA’s Transit Economic Requirements Model (TERM) format. TERM rates an asset’s condition on a scale of 5 (excellent), 4 (good), 3 (adequate), 2 (marginal) through 1 (poor)
  • To arrive at an SGR score for each facility, a weighted average was used based on each building system’s relative, typical replacement cost. This methodology has been documented in the overall condition assessment report.

Element Critical

Overview

CSIE provided an engineering evaluation of this data center co-location facility to correct an existing cooling deficiency and future cooling requirements.  CSIR recommended an improvement to the current refrigerated door solution, with an increased heat transfer and door capacity and additional redundancy. This technology would also be implemented in Element Criticals planned high density applications.

At the point of CSIE’s involvement the room was over heating and the refrigerant door solution was not able to neutralize the load. To compensate the client had added a 97-ton CRAC unit in the adjacent suite to capture the room over temperature conditions and keep the environment within control.  By implementing the recommendations, Element Critical was able to eliminate this CRAC unit and increase the leasable space within the room. With our successful modification CSIE provided a schematic design expansion to double the tenant’s IT capacity, rated at 30 KW per processing cabinet (over 500 KW) within their existing suite with liquid cooling supported for the application.

State of Bahia

Overview

The purpose of this high-level study was to assess existing conditions and make recommendations on improvements to achieve increased E-government, network, and IT capacities across several data centers in Salvador, Brazil. The data centers analyzed are owned and operated by the state of Bahia, and support various government agencies such as finance, security, and transportation. CSIE was tasked to perform site surveys on the three largest data centers and based on our findings, produce conceptual designs on each.

The conceptual designs addressed improvements to the physical space, mechanical, electrical and fire protection systems. These improvements took into account:

·        The existing state of the infrastructure

·        The mechanical and electrical capacities required to support projected IT hardware

·        The government’s desire that each data center have concurrent maintainability (Tier III)

·        The requirement that each data center would have the sufficient infrastructure in place to back up the other two data centers in the event of a disruption

CSIE was responsible for compiling the projected IT hardware based on interviews with data center stakeholders. These projections were translated to space requirements and mechanical and electrical loads, and CSIE’s architect and engineers developed conceptual floor plans, one-line diagrams, and riser diagrams accordingly. The narrative explaining these recommended improvements was accompanied by cost estimates for budgetary purposed.
