The mission of Hoque & Associates is to strive to build lasting client relationships through commitment, communication, innovation, and quality responsive service in order to establish and maintain its current standing as a premier provider of consultants.
Hoque & Associates, Inc. (HA) is a will-established firm composed of experienced professionals determined to bring the best quality product to the client. Now well into the second decade of operations, Hoque & Associates is proud to offer geotechnical consulting services, materials testing, quality control, quality assurance, and environmental engineering services. Hoque & Associates personnel apply collective expertise to meet a series of diverse challenges proposed by clients. By combining efforts in a true show of teamwork, personnel dedicate themselves to developing practical and cost-effective solutions to some of the most difficult of engineering challenges.
Hoque & Associates has completed several hundred geotechnical and materials testing projects in the Phoenix area, as well as all across Arizona. Hoque & Associates has the technical expertise, direct experience, range of qualified staff, and corporate commitment to successfully complete project work on time and within budget. Hoque & Associates is dedicated to pursuing innovative ideas and technology that can save clients money and time, while still adhering to the project objectives.
Hoque and Associates provides the services in the following areas:
Geotechnical Engineering and Field ExplorationIncluding sampling and field and laboratory soil testing; foundation analysis for dams, roadways, buildings and infrastructure; preparation of reports, including rock mechanics, slope stability and pavement section design.
Construction Materials Field and Laboratory TestingQA/QC field testing and inspection of common materials including soil/aggregate, concrete/masonry, asphalt concrete and special inspection of welding, structural steel and fireproofing.
HA has specialties in performing QA/QC field testing and inspection of liner materials for landfill construction and other liner installation.
HA has the capability of performing almost all types of soil testing. HA’s laboratory also perform testing for aggregates, cement concrete, masonry and asphalt concrete.
Stabilization of Inert Debris Landfill for Commercial DevelopmentHA has extraordinary experience in ground improvement especially with Deep Dinamic Compacton (DDC). DDC consists of dropping a heavy weight on the ground surface to densify (stabilize) soils or debris materials at depth. HA performs designing, monitoring, and performance evaluation services for stabilizing ground with the application of DDC. This type of stabilization reduces foundaton settlements, reduce seismic subsidence, permit construction on fills, densify garbage dumps, and induce settlements in collapsibloe soils. DDC helps reducing the environmental concerns related to overexcavation , materials hauling, and backfilling. Development on a debris landfill improves the property value at and arround the site and improves the whole community environmentally and aesthetically. HA’s example projects include: Tempe Market Place in Tempe, Rio Salado Commerce Park in Phoenix, and Dean Thomas Property. All these example projects were vacant land filled with inert (especially construction and demolition) debris after gravel mining. These sites have been stabilized with DDC for commercial developments (shopping mall, etc).
Vibration and Settlement MonitoringHA provide services on monitoring of vibration and settlement at existing structures during vibration or movement caused by construction of other activities in the vicinity of the structures.
The vibration monitoring devices include Minimate Plus Monitors manufactured by Instatel equipped with Raven CDMA Wireless Modem manufactured by Airlink Communications and triaxial geophone suplied by Geocon. The equipment facilitates remote sensing and data collection through cell phone modem telemetry and data collection software. These monitors have four channels with an external transducer to intercept any vibration or waves that pass through the media. The frequency response of the transducer is 2 to 300 Hertz and for higher frequency, the equipment has geophone to record such events.
The settlement monitoring basically consists of taking elevation readings of reference points of interests periodically during construction or settlement causing operations. The elevation readings are taken utilizing high precision survey equipment to monitor any minute change or movement.
Gamma-Gamma Logging and Crosshole Sonic LoggingHA is capable of providing services related to Gamma-Gamma Logging and Crosshole Sonic Logging to evaluate structural defects in existing deep foundations.
Gamma-Gamma Logging (GGL) is generally viewed as the most accurate non-destructive test method used to detect anomalies in Cast In Drilled Hole (CIDH) piles, known also as drilled shafts. Substantial drops in average bulk density readings from Gamma-Gamma tests are indicative of the presence of anomalies in the material surrounding the inspection tube. An anomaly is an unexplained change in the detected density homogeneity of the CIDH pile at a given depth, typically signaling contaminated concrete or a reduction in cross-sectional area. The anomaly is considered to be a defect when the intended performance of the pile is compromised by the anomaly. Structural, geotechnical, and corrosion concerns may all contribute to identifying an anomaly as a defect.
Crosshole Sonic Logging (CSL) is performed to further define the nature and extent of detected anomalies. Like GGL, CSL is a downhole NDE method that is utilized to determine the homogeneity of the concrete within CIDH piles. Instead of using a radioactive source to determine density in a tube, CSL is performed with high-frequency sonic pulses from a pair of probes located in two adjacent tubes. One tube contains a sonic emitter while the second inspection tube contains a receiver. By evaluating the time the sonic signal takes to traverse the distance between probes, the uniformity of the sonic properties of the intervening material can be determined.
Environmental AssessmentPhase I and Phase II environmental site assessment (ESA) associated with commercial real estate transactions and underground storage tank facilities.
Solid Waste EngineeringDesign and construction administration of pollution control systems including solid waste disposal facilities and liner systems for wastes and liquid impoundments.
Civil Design ServicesSite grading and drainage planning to comply with county and municipal requirements for land development including hydrologic analysis and preparation of site plans and drainage reports.
