BIM Modelling and Coordination

Our in-house BIM modelling team use the latest software available to model and coordinate our designed services with all other constants in the design team for a given project.

We have heavy invested in building our own Revit families to ensure that our designed services and accurate, allowing us to confirm floor and beam penetrations, set outs or clashes early in the design phase and to fully coordinate with all other services.

On complex projects we provide multiple printed views of coordinated services to assist the installing contractor and we can provide virtual 3D building fly-throughs.

On-Site Investigation and CCTV Service’s Locations 

Unless a site is a completely new Greenfields site - undertaking a detailed on-site services investigation is invaluable exercise. If any existing services are proposed to be reused as part of a new development, then we strongly recommend that they firstly be located and secondly the condition of the services is assessed to ensure that it is fit for purpose. 

Too often costing variations arise on existing sites when an existing drain or water main is found to be located under a new building or extension. Often when a service is assumed to be suitable but when the contractors on site locate it, they find that it is undersized, damaged or at an incorrect invert to be able to be used after all. 

Ground scanning, CCTV inspection and if necessary, excavation to confirm a drain invert are a very cost-effective solution to de-risk a projects contingency sum early on in the design phase. The Flow Consulting team personally undertake any required on-site investigation work and then accurately document those findings directly onto our design plans – providing design advice to mitigate risk if required in the concept design stage. 

Water Pressure and Fire Hydrant Flow Testing 

We have the staff and calibrated equipment to conduct hydrant tests. We carry out these tests with a comprehensive flow test report to determine what the available flow and pressure is from the hydrant main, to assist with consent and fire system design.

We liaise with local councils and/or Fire and Emergency in the Waikato area.
