2017 Brings in the New 2016 California Building Code

A New Code

2016 California Building Code

2016 California Building Code

On January 1, 2017, the State of California is adopting the 2016 California Building Code.  This affects the design and construction of new and existing buildings.  When and how the 2016 CBC will affect a specific building will depend on the local jurisdiction.

The 2016 California Building Code is based on the 2015 International Building Code.  Various California agencies add their own amendments to the 2015 International Building Code.  The 2015 International Building code is based on the following:

  • ASCE 7-10 including Supplement No. 1
  • ACI 318-14
  • AISC 360-10
  • AISC 314-10
  • TMS 402-13
  • TMS 602-13
  • 2015 AF&PA NDS
  • 2015 WFCM

The prior version of the building code 2013 California Building Code was based on the 2012 IBC.  Many of these code references to the 2013 CBC and the 2012 IBC have been updated.

California has its own amendments so that the 2016 CBC is a little different than the 2015 IBC.  For instance, the reference to the loading requirements of ASCE 7-10 Supplement No. 2 is added to the California Building Code.  Generally, most of the differences between the 2016 CBC and the 2015 IBC relate to school and hospital construction.

Free versions of the 2015 IBC2016 CBC, and other building codes are available.

Transitioning to ACI 318-14

One of the 2015 IBC references is American Concrete Institute’s Building Code Requirements for Structural Concrete and Commentary ACI 318-14.  ACI 318-14 has been completely reorganized from the previous ACI 318-11 edition.  Because of this reorganization, ACI has published free transition keys between ACI 318-11 and ACI 318-14, so that a designer can bridge the differences between the two editions.  These transition keys are in both English and Spanish.

Jax Kneppers Talks About Mobile Collection Technology at the 2016 AACE Annual Meeting in Toronto


Toronto SkylineJax Kneppers, President and CEO of Jax Kneppers Associates, Inc. and Imfuna, gave a presentation entitled “Mobile Collection Technology to Create Accurate Cost Estimates” at the 2016 AACE International Annual Meeting in Toronto, Canada, on June 27, 2016. The presentation was part of the annual event that spanned June 26 through June 29 that attracted cost estimators and engineers from all over the world.

Mobile Technology for Field Data Collection

The lecture focused on the following:

  • application of mobile technology for field data collection
  • database driven technology for efficient organization of data
  • advancing the professional practices by using cloud-based mobile collection technology
  • impact of mobile collection technology on the industry

Jax discussed the current practices of field data collection, which often use multiple devices such as digital cameras, dictaphones, note pads, drawings and tables, to capture different types of data. Using different  devices to separately capture dictations, measurements, notes, and photos made the entire process cumbersome. This is especially apparent when you start combining the massive amount of collected data from the different sources into a usable format. These current practices are laborious, time-consuming and inefficient.

The key to improve field data collection methods is technology according to Jax. With advances in mobile technology, one can consolidate the field tools into one device and noticeably improve the taking of photos and notes, and field sketching. Other advantages with using mobile technologies include better data resilience or integrity, and increased site mobility and safety.

Improved Inspection Efficiency

A comparison of time to complete common inspection activities between traditional methods and mobile technology methods showed an improvement of almost 64%. Since the data collected using the newer methods is digital, the speed in which reports, analyses and cost estimates were created dramatically improved.

The Team

The presentation was put together by Jax Kneppers, Dr. Borja Garcia de Soto, and Matthew Dick. Dr. Garcia de Soto has a PhD in Civil Engineering at Eidgenössishche Technische Hochschule Zürich, and has had extensive experience in civil engineering, project management, schedule analysis, cost estimating, BIM and forensic engineering. Matthew Dick is a construction consultant turned software developer at Imfuna and has a Bachelor of Science degree in Civil and Environmental Engineering from UCLA.

With a vast background in mechanical engineering, cost estimating, and forensic engineering, Jax Kneppers is the president and CEO of Jax Kneppers Associates, Inc (JKA) and Imfuna.

Analysis of Adverse Weather for Excusable Delays

Severe weather conditions are disruptive to construction. Contractors typically obtain time extensions for weather days beyond normal conditions. However, contracting parties often dispute the extent of weather-related time extensions. Typical industry contracts appear to overlook many important points that can provide an acceptable resolution. This paper classifies seven factors causing discrepancies in analysis of adverse weather for time extensions, namely, the definition of normal weather, weather thresholds, the type of work, lingering days, criteria for lost days, lost days equivalent due to lost productivity, and work days lost versus calendar days lost. An analysis of an actual weather-caused delay claim illustrates the impacts of those factors on the outcomes of the analysis. A contract should define anticipated weather delay days and their lingering days and provide threshold values for weather parameters to differentiate between predictable and unpredictable severe weather. The contract needs to direct how a time extension is granted in calendar days from work days lost and also address how a time extension is granted due to inefficiency caused by unusually severe weather. Future research may provide an appropriate mechanism for analyzing equivalent lost days to account for lost productivity.
