Estimating, tender and WHS support for civil and regional contractors.

Project delivery

Estimates built from real production rates, programmes crews can actually work to, and supervision that picks up problems before they become costs. That comes from time on the job: Scott McGlashan has worked in civil, agricultural and infrastructure earthworks since 2009, as operator, leading hand, supervisor, final trim grader operator and project manager. He now leads DDES.

Who we work for

Councils and asset owners

Client-side project management and supervision for restoration packages and capital works.

Principal and head contractors

Extra estimating capacity at tender time, and a project or site manager for packages you've won.

Agricultural and private developers

Irrigation, water storage, access roads, hangars and on-farm infrastructure.

Smaller contractors

An experienced project manager or estimator for one job, without adding a permanent salary.

Scope first, then a fixed fee

It starts with a short scoping call. We then quote a fixed fee per stage where the scope allows, and confirm scope, deliverables and reporting in writing before any work starts.

Conflicts

DDES also advises contractors on tenders. We check for conflicts before every engagement and won't act for both the principal and a bidder on the same work.
