The purpose of water storage tanks is usually to meet peak demands, such as fire flows and times of the day when water use is high. There are a few items to consider when selecting a new water storage tank for your community or industry. Traditionally, it has been a common practice of many water
Before the start of any project, HR Green construction professionals verify that the design will fit the existing field conditions. In some cases, as such with making sidewalks ADA compliant, the application of design standards is the responsibility of the construction engineer.
The challenges to transportation project designers are more difficult today than ever. Right-of-way (ROW), easements, utility adjustments, and the ability to efficiently stage construction while safely maintaining traffic are critical factors to keep projects on track, especially in constrained urban settings. Add to the mix are a broad range of regulatory clearances that must be obtained in a sequential manner during the National Environmental Policy Act (NEPA) process to keep the project on schedule. These clearances are often based on conceptual and preliminary design that if not thoroughly developed during the location and route studies phase can lead to rework and schedule delays later in the project life cycle.
The use of 3-D Design tools aids engineers in evaluating designs and the conditions present that can create construction delays, cause expensive changes to the design or could affect long term maintenance costs if not adequately analyzed at key steps in the design process.
2015 has been a year of recovery for many communities. As the economy has steadily improved, leaders in local governments have moved from survival mode to planning for a more predictable future.
When a building is being constructed or modified, or an addition to an existing building is constructed within a community, municipal plan examiners will review the construction documents prior to issuing a permit. Building inspectors will visit the site at various times to ensure contractors are producing a safe and durable structure; adhering to the approved documents.
Keeping up with changes in state laws can be a full time job for municipal employees. The experts in HR Green, Inc.’s Governmental Services Business Line review and keep up with the changes in Building Codes and Code Enforcement.

The 2014 U.S. Department of Transportation (U.S. DOT) National Bridge Inventory database found that there are more than 2,000 fewer structurally deficient structures than there were in 2013. However, that means more than 61,000 structurally deficient bridges are still in need of significant repair.
Many industries have some level of wastewater pretreatment before discharging to the local Publicly Owned Treatment Works (POTW). In the food and beverage industry, pretreatment with Dissolved Air Flotation (DAF) is common to remove fats, oils and greases, along with associated Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). These food and beverage companies are in the business of making their products, not wastewater treatment. So, often times, selecting the right piece of equipment can be a challenge.
