Estimates & Cost Planning
Independent project costing, scope review and budget guidance to help you understand what the project is likely to cost before major commitments are made.
Building Estimates & Cost Planning →Independent residential building consultancy for homeowners and owner-builders across Melbourne, the Mornington Peninsula and South-East Victoria, providing building cost planning, pre-build advice, tendering and project consultancy — with practical construction experience behind every decision.

RJD Building Consultants combines estimating, permit coordination, tendering and project consultancy with hands-on residential construction experience dating back to 1986.
The role is consultancy — helping clients understand cost, scope, sequencing and decisions — not operating as a volume residential building contractor.
Selected project images from Rob Dillon's residential building career. They show the construction stages, sequencing and site realities that inform RJD Building Consultants' advice today.
Some clients need a realistic cost before they commit. Others need help getting through permits, tendering and pre-construction. A smaller number want RJD involved throughout the build.
Independent project costing, scope review and budget guidance to help you understand what the project is likely to cost before major commitments are made.
Building Estimates & Cost Planning →Application coordination and liaison for Planning Permit and Building Permit processes, with additional Report & Consent applications where required by the RBS.
Planning & Building Permit Help →Trade scopes, quote requests, comparison of competing prices, procurement planning and practical advice before appointments are made.
Tendering & Procurement Services →Construction consultancy, coordination, cost monitoring, programme support, site attendance and reporting for selected owner-builder projects.
Residential Project Consultancy →Rob Dillon has worked in the building industry since 1986. After decades constructing residential projects and working directly with clients, trades, designers and consultants, his work has progressively moved into building consultancy and project coordination.
RJD exists to use that practical experience to help clients make better decisions before and during construction — without assuming every client needs the same level of service.
RJD Building Consultants is a consultancy service. Clients retain control of their project decisions and, where applicable, contract directly with their selected builders, trades and suppliers.

The first conversation is about where your project is now — not about forcing you into a large package. RJD can step in for one defined service or stay involved through construction where the project and client are a good fit.
Plans, site, permit status, budget and the problem you need solved.
Estimate, permits, tendering, pre-build coordination or a full consultancy engagement.
Clear deliverables, fees, client responsibilities and what happens next.
Use the advice as a stand-alone service or progress into the next stage when required.
RJD does not aim to run a volume portfolio of full-build engagements. Full Package Project Consultancy is accepted selectively so the projects taken on can receive direct involvement from Rob.
Pre-build consulting remains available separately, so a client can use RJD for estimating, permits, tendering or getting the project ready to build without committing to a full construction consultancy service.
Clear, defined fees for common pre-build services. More complex or additional consultancy work is charged at the published hourly rate unless otherwise agreed in writing.
Full Package Project Consultancy is offered by separate agreement and subject to project suitability and availability. The fee structure includes an $895 + GST non-refundable sign-up fee, a $1,795 + GST pre-start retainer credited in full against the final consultancy fee, and a flat consultancy fee equal to 5% of the GST-inclusive Approved Construction Cost. The 5% consultancy fee itself is GST-inclusive.
The aim is not to add another layer of paperwork to a residential build. It is to help the client see cost, scope, programme and decisions clearly enough to keep the project moving.
RJD Building Consultants provides consultancy and advisory services rather than residential building contracting.
