When excessively wet soils are encountered during construction, synthetic geogrids and geofabrics can be used to improve soil separation and stabilization characteristics so construction projects can proceed.
Special inspections are confusing! Here are answers to the six most frequently asked questions regarding special inspection requirements, responsibilities, budgets and how they impact occupancy permits.
Weather patterns have changed, so we can’t just take it for granted that what we did in the past will work well now and into the future. Planning for the likely occurrence of several of Ohio’s “new normal” rain events during construction means engineering, budgeting and scheduling for temporary site drainage, de-watering operations, soil modification and soil stabilization approaches.
2017 Year in Review
The year’s most unusual projects, new services added, charitable organizations supported, and other notable GCI milestones.
Steel Inspection Tips for Every Building Owner and Contractor - October 2017
Steel inspection guidelines and tips that every contractor, building owner, and facility manager should know to help construct steel building components and implement preventive maintenance programs to reduce the risk of emergencies.
Welder Certification and Welding Procedures Qualification – October 2017 addendum
Maintain compliance and avoid schedule delays by making sure each welder’s welding performance qualification (WQTR) is AWS certified and the production companies, fabrication shops and field erection companies working on your project have qualified all welding procedures (WPS).
Revisions to Ohio UST Regulations, Vapor Intrusion (VI) solutions, and GCI’s expanded welding lab - June 2017
Any newly discovered Underground Storage Tanks (USTs), even on projects already under construction, must comply with the new rules published in September 2017. Plus, new passive vapor mitigation system option for new construction projects, and GCI completes new fully-equipped in-house welding laboratory for welder performance qualification (WQTR) and welding procedures qualification (WPS).
Vapor Intrusion Solutions - June 2017
Combined technologies treat chlorinated and other solvents at former manufacturing site redeveloped for residential use.
The Rise of Post Tensioned Construction - March 2017
Post-tensioned (PT) concrete construction is a method of reinforcing (strengthening) concrete or other materials with high-strength steel cables or strands. The PT method creates longer spans more efficiently than traditional reinforced concrete. Buildings can have larger interior spaces unobstructed by vertical structural supports, irregular or random loads can be accommodated, and longer spans can be achieved with less concrete and rebar material.
How to Fast-track FRA Inspections - November 2016
To provide timely inspections for clients, contractors and property owners, in 2015 the City of Columbus Inspection Department approved GCI to perform FRA inspections in lieu of the City’s inspectors.
What You Need to Know About Hot Weather Concrete - July 2016
Damage to concrete caused by hot weather can never be fully alleviated. So proper management of both construction practices and the concrete mixture are essential to minimize the effects of hot weather and prevent decreased strength, decreased durability due to cracking, and increased variability of surface appearance.
Making Space for One Million People - June 2016
Many of central Ohio’s new residents will live and work in buildings constructed on redeveloped sites and infill properties. Redevelopment reduces land consumption and increases the efficiency of infrastructure. But there are geotechnical and environmental challenges that developers, contractors and architects must consider when sites transition from one- or two-story structures to buildings with as many as 25 stories.
Downtown Columbus Redevelopment Projects - June 2016
This map shows recent Columbus sites that have been redeveloped from one- or two-story buildings to mid- and high-rise structures.
Cold Weather Masonry Practices & Protection - January 2016
Cold weather masonry construction may proceed at temperatures below freezing provided mortar/grout ingredients are heated and new masonry construction is protected from freezing ambient temperatures. Read more about recommended construction practices for cold weather masonry projects.
2015 Year in Review – December 2015
2015’s notable projects and milestones.
Tips for Staying in Compliance - October, 2015
Updates and compliance tips for Asbestos Containing Material (ACM) Surveys, Clean Water Rule revisions, and lead-based paint inspections. Plus, GCI approved to perform city of Columbus FRRA Inspections.
Heritage Cooperative Six-Day Continuous Concrete Pour - July 2015
With extraordinary preparation, a highly skilled crew and trusted partners, a lot can be accomplished in just one week. Take a look at the progression photos as 500 truckloads of concrete became a 14-story grain silo during a six-day continuous pour.
Concrete Facts Every Building Owner and Contractor Must Know - May 2015
Proper management of moisture and relative humidity must begin during building design and continue throughout the building’s useful life. Here are 10 essential moisture management factors that every general contractor, construction manager, building owner, architect, and property manager should know in order to properly manage risk, project schedules, and building maintenance.
Cold Weather Concrete Placement - January 2015
Construction projects needn’t stop due to freezing temperatures and winter weather, but appropriate measures must be taken so that cold weather concrete placement is successful.
Building Solid Foundations on Wet Soils - April 2014
How to use soil stabilization and soil modification to keep your projects on track despite wet site conditions.
Impact of the New Phase I ESA Standards & Funding Environmental Assessments and Cleanup Projects - January 2014
Review the five key changes that will affect how Phase I ESAs are conducted and the impact on projects. Plus, funding sources for environmental assessment and cleanup activities for a redevelopment project.
Special Inspection Requirements for Occupancy Permits - October 2013
Special inspections must be performed throughout the construction process to avoid the denial of occupancy permits, project delays and costly rework. Here are answers to the most common special inspections questions fielded by GCI staff.
Strategies for Hot Weather Concrete Pours - July 2013
pouring concrete during hot, dry summer weather creates unique challenges that must be properly addressed to avoid schedule delays and costly remedial actions. Here are strategies to help make sure the concrete pours on your project are prepared, finished and cured properly.
