Heart of Doha in Doha, Qatar, earns LEED Platinum certification for design and energy efficiency; Groundwater Remediation System in Northern Illinois, reduces the level of ammonia in the influent from more than 1,000 parts per million to less than 1 part per million; 18th Street Substation in Birmingham, Alabama, gets two new 115-kV undergound pipe-type line segments.
Cherishing Ancient Culture in a Modern Oasis
Positioned in the city's historical center and adjacent to the state palace, Emiri Diwan, the 35-hectare Heart of Doha epitomizes DOHALAND's five pillars — Heritage and Culture, Innovation, Sustainability, Enrichment, and Environment — in a dynamic district designed to preserve Qatari culture in a community setting where people can live, work and play.
Launched on March 3, 2009, DOHALAND is led by the progressive vision of Her Highness Sheikha Mozah Bint Nasser Al-Missned, who mandated the creation of leading-edge urban living concepts\ that build on traditional Qatari architecture and design.
As the executive architect of phase one of five, Burns & McDonnell leads this LEED® Platinum and Gold design. Heart of Doha's architecture rediscovers Qatar's heritage with an emphasis on proportion, simplicity, space, light, layering, ornament and response to climate.
The interconnected buildings are oriented to take advantage of off-shore northerly winds, while colonnades and green spaces shade streets. To combat urban sprawl and dependence on car travel, the Heart of Doha will feature up to five subterranean levels with underground lanes for service and delivery vehicles, dedicated cycling lanes and a tram connecting the district to the rest of Doha. Other sustainable designs include maximized water conservation, energy efficiency and reduced carbon emissions.

Cleaning Water from the Ground Up
Burns & McDonnell has operated an extensive groundwater remediation treatment facility since July 2008, removing ammonia, phenolics and arsenic from beneath a former manufactured gas and coke plant site. The 10-acre treatment zone includes extraction and reinjection wells that pump contaminated water to and from the bottom of the aquifer. "The treatment method and operation and maintenance requirements are atypical," says Jeff Pope, manager of environmental services in the Burns & McDonnell Chicago office. "The process is an innovative application of sequenced batch reactors." They reduce the level of ammonia in the influent from more than 1,000 parts per million (ppm) to less than 1 ppm and phenolics from over 100 ppm to virtually non-detect. Arsenic is removed as part of the biomass sludge wasting process. The treated water is reinjected into the aquifer to enhance natural attenuation. Contaminant concentrations in the plume can vary widely across the site. Groundwater is treated in 7,200-gallon batches for about 8 hours each, creating the flexibility to treat varying concentrations. The process also requires comparatively large overall capacity of 160,000 gallons of equalization tanks and two 100,000-gallon reaction tanks. Remediation will be complete after three to four years.

Urban Power with a Pretty Face
Slow, steady load growth in downtown Birmingham created the need for a new substation. Alabama Power turned to Burns & McDonnell and a joint venture partner for engineer-procure-construct services to bring greater electric reliability to the densely developed area. The team installed two 115-kV underground pipe-type line segments tied into an existing underground line; 15-kV ductbanks between the new substation and existing overhead lines; and two overhead fiber optic circuits. "The combined business and residential area required more than your standard substation perimeter fencing," says Darin Penner, Burns & McDonnell project manager. "Because the neighborhood is near the University of Alabama-Birmingham, a decorative architectural wall helps screen the substation from public view." Street closures in the area were minimized to aone-lane reduction on the north and temporary closure on the east. "This 10-month construction effort will lead to greater electric reliability for our downtown customers," says Casey Allums, project coordinator for Alabama Power. "Taking elements underground and going the extra mile for the neighborhood resulted in a facility that meets our needs and the needs of nearby residents."
