This presentation brought to you by Engineering General Practitioners (EGP) discusses some of the history and nuances of C2 capacities for post installed anchors in concrete within a NZ context. Robert Hudson from Python Fixings discusses the history and evolution of C2 testing protocols, common areas of ambiguity and misinterpretation and the application of C2 values in accordance with NZS3101:2006 among other topics. This topic is not well understood by many engineers and it is hoped that the presentation will help engineers understand what the values they use in design are actually representing.

How building surveyors can help general practice engineers with their projects, what services building surveyors can offer and how together a complete all-round service can be provided to clients. The presentation will discuss building forensics, the challenging landscape of expert witnesses, historical buildings and a case study of a pre-1991 strawbale house with no CCC. In New Zealand, building surveyors ensure the safety, compliance, and quality of buildings by providing services such as pre-purchase inspections, managing building consents, advising on building code adherence, and assessing conditions for property owners, lenders, and insurers. They are the "guardians of New Zealand's buildings," inspecting plans, monitoring construction, testing and monitoring property-related matters, and providing expert reports and advice on building issues. This talk will discuss the specific relationship that could exist between building surveyors and engineers.

This presentation outlines some of the engineering principles adopted when designing buildings from more ’natural’ building materials. The structural behaviour of the materials is discussed, the mechanics of their strength and stiffness, and the interplay of strength and stiffness with durability. Example projects will show various issues which need to be addressed during design, and show a variety of successful projects across New Zealand. The New Zealand Earth Building Standards will be discussed, and their interaction with other NZ codes. We will touch on the thermal performance of the materials, and discuss their sustainability credentials and carbon footprint calculation.

The Engineering General Practitioners (EGP) present this webinar on Gravel rafts versus Timber Piles, looking at financial cost and sustainability. Ian Watson, EGP committee member, shares with us his many years’ experience in designing houses and light industrial structures and this webinar follows his presentation at the recent SESOC conference. Many sites now call for SED foundations due to soft soils – peats, expansive soils, and liquefaction-risk soils. A common solution suggested by the Geotech. Report is a hardfill raft extending beyond the building platform, and in some cases 1m thick. Are there alternatives and how do we compare them on cost? How do they compare using sustainability comparisons? This presentation looks at two alternatives and proposes a working spreadsheet to assist designers’ approximate materials and construction costs, in order to make useful comparisons. The same methods are then used to compare sustainability outcomes.

This webinar is brought to you by the Special Interest Group for Immigrant Engineers (SIGIE). Presented by Andrei Tupaz, this webinar discusses how many IT professionals start their careers without a formal IT degree, developing skills through self-learning, personal projects, and hands-on experience. Reputable online resources and courses provide opportunities to gain knowledge and refine technical skills. Volunteer work, homelabs, and contributing to public codebases offer hands-on experience, while networking and peer collaboration foster growth and build valuable connections. This webinar explores how these approaches help to break into and advance in IT.

The Special Interest Group for Engineering General Practitioners present this webinar where Tony Stuart of Compusoft will present the way that SAP2000 can analyse and solve a pre-determined structural problem. This presentation follows on a previous look at SpaceGass. Tony Stuart specialises in the finite element analysis of structures of all kinds. He routinely advises other engineers throughout New Zealand on the correct use of analysis software in his role as the principal support agent for CSI software in New Zealand. Tony also has extensive experience in seismic assessment and retrofit of existing structures and was a contributor to the New Zealand Industry NLRHA Guidelines published by Structural Engineering Society New Zealand (SESOC).

This webinar is brought to you by the Special Interest Group for Engineering General Practitioners (EGP), presented by Vic Summerfield from Architectural Promotions Ltd, a company that offers technical support to engineers and architects. They specialise in presenting reputable building systems, materials and solutions commonly specified in design projects and newer ones that may not yet be included in the Codes. The material covered includes the engineering aspects of new Mitek products, Prolam timber, Metwood Aluminium Coatings, EPS panels, some insulation products, Northpine timber, Tru-Gard safety barriers, KLC cladding, rigid air barriers and Enveloped Eliment Insulation.

The Special Interest Group for Engineering General Practitioners (EGP) invite you to join this webinar that will focus on the software workflow for a simple problem suitable for EGP-type work. This webinar will demonstrate how the Space Gass structural analysis software program can be used to assess a structural problem, and how it can provide useful results. The identical problem shall be the topic of our July webinar, using SAP2000 software. Our presenter in Ben James who has around 15 years of experience as a consulting engineer with the last 3 years spent as the CEO of Space Gass. Prior to joining Space Gass Ben ran his own consultancy focused on high end architectural housing projects following stints at a range of Australian consultancies including AECOM. Ben has a Bachelor of Engineering Civil degree, as well as an Masters of Business Administration, both obtained in Australia.

This webinar brought to you by the Special Interest Group for Engineering General Practitioners (EGP) introduces some of the key challenges with access and boundary conditions for the design and construction of retaining structures, which include: - Where is the boundary and whose land does it retain? - How will the retaining wall affect ground movements in the future (above and below the retaining wall)? - How do we assess the stability of temporary slopes and batters required for retaining wall construction? - Geotechnical Investigations - how much do we need? - what is the correct surcharge for temporary and permanent cases?

This webinar delves into the specifics of soil testing methods and their practical applications in structural and foundation engineering. Our speaker, Andrew Holland, a Principal Geotechnical Engineer from HD Geo will guide you through the key techniques used in the field, including: - Dynamic Cone Penetrometer (DCP) Testing: Why use it, where it fits into practice - Shear Vane Testing: Best-suited soils and interpreting results. - Interpreting Soil Parameters: Estimating values for cohesion (c’) and friction angle (φ’) without a triaxial test. - Correlations between DCP and Shear Vane: Practical insights for foundations and retaining walls. - Terzaghi’s Influence: Where classical soil mechanics principles apply. - Dos and don’ts of testing in real-world situations. This session is perfect for general practitioners who want to deepen their understanding of soil testing and its implications for design and safety. Bring your questions! There will be time for live Q&A with Andrew at the end of the webinar. Andrew Holland is a Principal Geotechnical Engineer and Owner of HD Geo. Andrew has 22 years of experience in geotechnical engineering New Zealand and the UK. He has worked extensively on projects involving foundations, retaining walls, and geotechnical design.

The Special Interest Group for Engineering General Practitioners bring you this webinar presented by Mark Moppett. Small project's design can have loaded areas that can easily be missed. Have you folllowed through with each of the load types to and locations ensure all loads are transferred to the foundations? Even a house design can have some traps to watch out for. Find out more.

Part 2 of the webinar addressed basic design concepts and some typical construction challenges are highlighted. In addition, the proposed NZGS guidance document for Stepped Retaining Walls (currently under development) is briefly introduced and discussed after Martin's presentation.
