Soil testing requirements can be prepared and reviewed for you project specifications. The review will ensure that all testing is in accordance with the latest acceptable standards and that the frequencies are in line with acceptable construction practices.
A complete Geotechnical and materials testing laboratory is operated at our headquarters. We offer a wide range of laboratory testing services including Triaxial Shear Testing, Consolidation Testing, Permeability Testing, soil index testing, moisture/density testing as well as many other tests.
Field monitoring and testing of soil fill materials using the Sand Cone and Drive Cylinder methods. The field density values are compared to the laboratory values for the soil and the Client is provided with real-time information as to the status of the fill material compaction.
Using ASTM methods our engineering staff will determine the suitability of the excavated foundation to meet the minimum load bearing requirements for your project.
Staff Engineers are trained and experienced in the subjective use of the Proof Roll method to determine road and parking lot subgrade and compacted base suitability for pavement placement. By using this investigative technique potential failures in the subgrade can be identified and repaired prior to asphalt placement.
Concrete testing reports are prepared or reviewed for your project specifications with regards to its requirements. The review will ensure that all concrete testing is in accordance with the latest acceptable standards and that the frequencies are in line with acceptable construction practices.
A review of the operations of a Ready Mix Concrete Batch Plant, by experienced employees, to ensure that the mix design required for your project is being produced.
Verify the concrete mix design for your projects, using our lab capabilities. If needed, we can provide a complete concrete mix design tailored to your specific project needs.
Field and laboratory testing services are provided for all types of mortar and masonry materials. In the field we can monitor flow and mold compressive strength cubes or build compressive strength prisms. In the laboratory we can determine the compressive strengths of the mixes.
With over twenty (20) American Concrete Institute (ACI) Grade 1 Field Testing Technicians on staff, testing ready mixed concrete as it is delivered to your project site is no problem. Tests such as slump, temperature, unit weight, entrained air content and molding of compressive or flexural strength specimens are routinely performed. Testing concrete as it is delivered to your project site is the first step to ensuring that the materials you are using will meet your project requirements.
The three testing methods range from the non-destructive Swiss Hammer and Windsor Probe, to the destructive methods of physically removing core samples from the body of concrete. The Swiss Hammer or impact hammer method provides the Client with an approximate strength of the concrete within 250 psi. The Windsor Probe is slightly more accurate and can determine the compressive strength of existing concrete within approximately 100 psi. The ultimate test to determine the compressive strength of hardened concrete is to physically remove core samples and have them tested in the laboratory for compressive strength.
Post tensioning of slabs will be monitored by trained staff engineers who will mobilize to your site. The engineer will observe all post tensioning operations and provide a detailed report outlining the cables pulled, the percent elongation and the pass/fail criteria.
Floor flatness and levelness is determined by using two (2) Dip Stick devices. Many manufacturing and retail facilities require this testing to ensure that the concrete floor slabs are within their project tolerances. The testing is performed as soon as the ready mixed concrete is capable of supporting the weight of the engineer. Should out of tolerance areas be identified the concrete contractor can re-finish the areas before the concrete is hardened.
A review will ensure that all asphalt testing is in accordance with the latest acceptable standards and that the frequencies are in line with acceptable construction practices.
A review of your Asphalt Batch Plant, by our engineers, to ensure that the mix design required for the project is being produced. If required we will obtain all samples required to verify the mix design and other criteria. These samples are then returned to the laboratory for detailed testing.
Our materials testing laboratory can verify the asphalt mix design for your projects. If needed, we can provide a complete asphalt mix design tailored to your specific project needs.
In the event of a pavement failure on your project, we can perform in-situ testing of the asphalt and the underlying base materials to assess the reason for the failure. This testing includes coring the asphalt and performing laboratory testing on the samples obtained as well as augering through the underlying base and sub base materials to determine the suitability of these materials for road base construction.
Since 2000, United Consulting has performed NPDES construction site inspection and monitoring services keeping in step with the NPDES permitting requirements since its inception. We take an active role with associations and groups that help guide the development of the industry such as the Council for Quality Growth, Consulting Engineers Council of Georgia (CEC) and the American Consulting Engineers Council (ACEC). Our NPDES certified professionals have years of experience solving NPDES construction issues in the State of Georgia enabling our clients to become compliant with local ordinances and Georgia laws and NPDES General Construction Permits.

Effective August 1st, 2008, the Georgia Environmental Protection Division (EPD) is re-issued the NPDES General Permits GAR100001, GAR100002, and GAR100003 for Storm Water Discharges Associated with Construction Activity. The following is a summary of the major changes to the new permits.
Sites that discharge storm water into an Impaired Stream Segment, or within 1 linear mile upstream of and within the same watershed as the Impaired Stream Segment, as listed on Georgia’s 2008 and subsequent 305(b)/303(d) List for the criteria of “Bio F” and/or “Bio M”, must satisfy the additional requirements of Part III.C of the new permits. Part III.C will not apply to construction activities for Stand Alone and Common Development projects if the NOI is submitted within 90 days of the effective date of the permits and will not be applicable to infrastructure projects if the NOI is submitted prior to January 1, 2009.
Total disturbed area for construction sites will be limited to no more than 50 acres at one time without prior written authorization from the appropriate EPD District Office. For Common Development projects with unsold/undeveloped lots, the Primary Permittee may submit a Notice of Termination only after all construction activities have ceased for a minimum of 90 days, final stabilization has been achieved, all secondary permittees have submitted NOT’s, and the site is in compliance with the permit. After submitting the NOT, the primary permittee shall notify the legal title holder or the purchaser of any remaining undeveloped lot(s) that they will become tertiary permittees under the permit and are responsible for implementing the requirements of the permit.
Important: All existing sites that have not yet submitted their Notice of Termination under the old permits are required to submit the new Notice of Intent within 60 days of the effective date of the new permits. Copies of the new permits, new NOI and NOT forms, and the current 305(b)/303(d) lists can be found on the Georgia EPD’s website
