The Contractor's View of the Window Package

Contractors don't make windows — they buy them. Four tools that make the purchasing and coordination work.

1

Window Package Takeoff

From the architect's drawings, extract every window type, count, and size. Takeoff runs in 2-4 hours for a 30-window residential project, 1-2 days for a 200-window commercial build. Output: quantified schedule ready for supplier RFQ — not a rough guess.

2

Multi-Supplier RFQ Comparison

Send the same schedule to 3-5 suppliers, receive their quotes back in the same format, compare like-for-like on price, lead time, warranty, and performance. Normalises varying quote formats so you're comparing apples to apples — genuinely the biggest purchasing advantage in window contracting.

3

Cost Plan Integration

Window package cost feeds the overall cost plan with correct coding (NRM2 element codes in UK, CSI codes in US). Updates to window spec or size automatically reflow to cost plan. No more of the classic 'windows came in £40k over budget' because someone didn't update the cost plan after a design change.

4

Programme & Lead-Time Management

Each window has a supplier-committed lead time. The app builds a programme view showing when to order to meet target install dates. Alerts fire automatically if an order slips past the critical-path date — catching programme risk early, before it hits the site.

Frequently Asked Questions

Is this different from estimating software like Bluebeam?
Complementary. Bluebeam is great for general takeoffs and markup. Doorwin is specific to the window package — richer data per window (profile, glass spec, hardware), built-in supplier comparison, and the programme/lead-time view. Use Doorwin for the window element; Bluebeam for everything else.
Can we run multiple projects at once?
Yes. Projects are organised separately with per-project settings (client, site address, cost plan codes). A typical main contractor runs 3-8 live projects with Doorwin at once. Reporting rolls up across projects for procurement pipeline visibility.
Does it integrate with our construction management software?
Yes, with the main platforms. Procore, PlanGrid, BuildTools, and Asta Powerproject all have direct integrations. Window package data pushes to scheduling, RFIs, submittals, and procurement modules without re-entry. Custom integrations with in-house systems are possible via REST API.
Is it useful for smaller (£500k-£2M) projects?
Yes — arguably where it has the most value. On a £50M tower, the window package justifies a dedicated purchasing specialist. On a £1M housing scheme, the project manager handles procurement themselves — and Doorwin gives them the tools to do it without a dedicated estimator. Time saved per project: 15-25 hours.
