Residential Projects
2022: Residential Developments, Whangarei
See Portfolio Item 2.0: Residential Housing Development
Project: New build, offering Geotechnical and structural engineering design services. Concurrent development projects totalling 40 single and two-storey residential units. Original design fee apx $100k.
Role: Project Management, Design Coordination and Construction Monitoring
Project Management
- Tender preparation: Initial scoping and pricing
- Client negotiation and liaison
- Negotiation of variations totalling apx 50% of original design budget
- Design meetings and liaison with external design parties
Design Coordination
- Coordination of Geotechnical reporting and assessment
- Earthworks plans, cut/fill
- Coordination of Structural and Foundation Design
- Existing “standard” building templates existed however these templates were limiting, and majority structures had design changes that required structural verification.
- Repetitive work: created efficiencies through standardisation of design spreadsheets, and standard details
- Design of internal timber framing elements outside NZS3604, including:
- Floor and roof beams, lintels, stairs,
- Ribraft foundations for poor soil conditions
- Bridging piles (for civil services)
- Timber and concrete retaining walls up to 3.0m high
2022: Residential basement excavation, Wellington
See Portfolio Item 3.0: Concept Design & Constructability
Project: Alteration: Consultation for development of basement structure beneath existing 1960’s residential building.
Primary contact for all parties and effective project manager.
Existing concept design for basic concrete basement walls deemed not feasible for construction.
Project site on mountainside - extreme slopes. Soil excavation undermines the building and adjacent properties. Constructability was the main challenge; concept design revolved almost completely around constructability. Investigation into potential foundation systems, construction methodologies, consultation with piling contractors.
Role: Project management and Concept design
- Slope stability analyses
- Scala, borehole and CPT testing across site
- Methodology:
- Demolish front portion of structure, allowing plant access to building
- Install secant walls within existing structure
- Retains soil behind existing building and adjacent properties
- ECI with piling specialist.
- Utilise small piling rig to fit within building
- Demolish existing flooring and install steel beams
- Acting as both temporary propping, and permanent replacement for existing timber piles supporting structure above
- Finally possible to excavate soil beneath building
- Further constructability challenges regarding installation of drainage
- Utilise weepholes and internal drainage system
- Shotcrete to form basement walls
- Concept drawings done on Bluebeam
- Project put on hold due to financing issues after early contractor involvement. Construction was deemed too expensive. Expected to resume design in 2023.
