What is the advantage of dealing with grand engineering?
Grand Engineering has shown many examples of assisting clients in communicating from the initial design, through to the building phase. Making the experience more than just a design. We will assist you to find solutions where required to keep your project moving and minimise delays.
What’s the next step after receiving my completed architectural plans?
Contact Grand engineering to determine the type of construction you are looking to build and we will assist you with a geotech report, stormwater, and structural design solution.
Do I need a geotech report?
Yes . Your site will need a site specific geotech report for the engineer to review and complete the structural design that will best suit you site application. This will enable the engineer to complete the most economical design.
What type of piers are used in Engineering designs?
At Grand Engineering we adopt the most suitable pier solution to suit your site and application, there are different types of piers such as:
-
Concrete piers
-
Screw piers
-
Bucket piers
-
Timber piles
What stages do I need inspections during the build?
There are many different types of inspections. You will require inspections at different stages through the construction process: such as:
-
Pier inspections
-
Steel Reinforcement inspection
-
Structural steel inspections
-
Structural Timber inspections
Do I receive certification?
Once Grand Engineering completes the structural design you will receive the design certification. During construction Grand Engineering will inspect the works and issue you a certification as a result of the successful outcome of the structural inspection.
Does a concrete slab suit all sites?
A concrete slab can be used on many different site applications. When it comes to sloping sites, it may be more cost effective to consider other alternates. Grand Engineering can review your site to assist in your construction methodology.
What is required if I have a steep sloping site?
If you have a sloping site greater than 11% slope you will need to get a specific slope stability report that will advise the slope risk and the design advise that assists the engineer in the design.
What if I am building in a marine environment?
If you’re building within a marine environment the engineer will have to review all the Associated Australian Building Codes and ensure his design specifies the correct materials to meet the relevant codes.
What height does an engineer need to design my retaining wall?
Most councils will advise the height required that an engineer would need to design the retaining wall. Grand Engineering can assist you in completing a retaining wall design.
Does a driveway need to be designed by an engineer?
The driveway for your home is a structural component of your build and Grand Engineering recommend the driveway should be designed by a structural engineer.
What if I have a crack in my concrete slab?
Depending on the nature and the location of the cracking it could be something that is minor and is only aesthetic or it could be a major crack. Grand Engineering will assess the cracking and prepare a report of its level of severity.
When do I require a stormwater design?
When there is an increase in the roof area or the impervious area (eg: driveways, pathway etc) as a result of the proposed development. You will need a stormwater design by a qualified engineer to manage the excess water overflow on the site.
Do I need an engineer for a house extension?
The house extension is no different to a new build from a structural point of view, you will need to engage an engineer to complete a structural design, your extension may require a Structural Adequacy report on the existing structure prior to starting the design.
Does the wind effect my build?
The wind classification is completed in conjunction with the site specific Geotech report. The wind classification will be used by framing and roofing manufacturers. The wind classifications are: N1, N2, N3, N4,N5 AND N6
