What we do

The discipline between ownership and the field.

Projects that end well share one thing: a team on the owner's side that has done it before, holding the budget, the schedule and the brand to account every week. That is the job.

01

Development management

Program definition, master schedule and master budget, consultant selection, brand and operator coordination, lender reporting.

02

Preconstruction & cost

Budget build-up from real quantities, value engineering that protects design intent, allowance strategy, GC and subcontractor proposal analysis.

03

Procurement & contracts

GC selection and RFP, GMP negotiation, owner-direct purchasing, logistics planning for remote and island sites.

04

Construction through opening

Site leadership, change and claims control, quality against brand standards, FF&E and OS&E coordination, commissioning and handover to operations.

Budget and proposal review, fixed fee.

Owners, lenders and family offices: before you sign a GMP or fund a tranche, we read the contractor's numbers the way the contractor does and tell you what is real. Two weeks, written report, fixed fee.

Wemhaner Development is built for owners who want senior people, not a staffing chart. Adam leads every engagement personally and brings a standing bench of specialists he has worked with across decades of hotel projects, assembled to fit each project's scope, geography and capital structure.
