Construction management.
What it is, how it differs from a general contractor, and why an open book puts you in control of cost and quality.
Construction Management
What is construction management?
Construction management is a transparent project-delivery method. Under the open-book agency model, you contract directly with each trade while the construction manager governs budgeting, procurement, scheduling, quality control and coordination — from the first drawings through to final completion.
How is a Construction Manager different from a general contractor?
A general contractor signs every trade agreement and gives you one price, with the margin and assumptions hidden inside it. A construction manager holds none of the trade contracts and takes no markup on the work; you hold each contract directly and see every cost. One model profits from the price; the other is paid to protect it.
What is the open-book agency model, and how does it protect me?
In the agency model you hold each trade contract in your own name and the practice earns nothing from the trades, so nothing is marked up and nothing is hidden. Every scope is competitively tendered, every invoice is yours in full, and nothing of consequence proceeds without your written approval.
Who holds the trade contracts, warranties and tax position?
You do. Every trade contract is signed in your own name, and the trade relationships, warranties and tax position remain yours to keep. The practice holds none of them.
How are trades selected and competitively tendered?
Each scope is tendered on a defined, like-for-like basis and presented to you as a true comparison, with a recommendation. You approve the selection. Competitive tendering on resolved drawings is what keeps the budget honest.
How do you control cost and schedule through the build?
From resolved drawings and competitive tenders we build a detailed budget and a working construction programme, then track both continuously — reporting cost against budget, identifying the critical path, and flagging issues while options are still open and inexpensive.
How are changes and change orders handled?
Nothing of consequence is committed without your written authorisation, and the cost record is reconciled continuously. Small revisions are not allowed to accumulate invisibly; you always see the cost and schedule impact before a change proceeds.
What does a Construction Manager actually do day to day?
Tender and award scopes, coordinate every consultant and trade, run and reissue the schedule, supervise quality on site, track and report cost, and govern change — one office accountable for the whole, rather than many parties each responsible for a fragment.
How is quality controlled and documented?
Through a single coordinator who reconciles the work of every consultant and trade, on-site supervision, and a documented record of cost, correspondence and approvals — so the project can be read, and audited, at any moment.
How is risk managed on a large or complex home?
Ambitious houses fail in the coordination, not the building. Resolved drawings before tender, competitive procurement, a single point of coordination, a programmed schedule, governed change and full documentation are the disciplines that keep a complex build on course.
