I hold a degree in engineering. I offer Floor Plans, Elevation and 3D Models for residential construction along with quantity estimates. Ancillary billable services include desk research, tendering (obtaining multiple proposals), preparing comparative statements, verifying bills of quantities, reviewing contract documents, preparing lighting and plumbing schedules, coordinating with Architects, Designers and other stakeholders. Cost savings achieved through competitive bidding and/or negotiations come with premium price or gain-share.
