Workflow

Overview

CaseMark's TI Work Letter skill drafts comprehensive Tenant Improvement Work Letter exhibits for commercial leasing transactions. The AI analyzes your lease terms, allowance structure, and building requirements to produce a detailed, deal-specific exhibit governing design approval, construction, and payment of tenant improvements.

Drafting Tenant Improvement Work Letters is one of the most time-intensive tasks in commercial leasing. Each exhibit requires careful coordination of allowance mechanics, multi-phase approval processes, construction requirements, and completion criteria—all while ensuring alignment with the underlying lease terms. A single missed provision can create costly disputes during build-out.

CaseMark automates the drafting of TI Work Letters by analyzing your lease agreement, allowance terms, and building rules to generate a comprehensive, deal-ready exhibit. The AI ensures all critical sections—from definitions and design approval to disbursement mechanics and substantial completion—are included and properly cross-referenced, letting attorneys focus on negotiation rather than document assembly.

Questions

What documents do I need to generate a TI Work Letter?

You'll need the executed or draft lease agreement, TI allowance terms (total amount, per-RSF calculation, eligible costs), and any building rules or contractor requirements. CaseMark uses these inputs to draft a comprehensive, deal-specific Work Letter exhibit.

Can CaseMark handle different TI allowance structures?

Yes. CaseMark supports various allowance structures including lump-sum amounts, per-RSF calculations, one-time allowances, and replenishable funds. The AI adapts disbursement mechanics and over-allowance provisions to match your specific deal terms.

Does the Work Letter include construction approval timelines?

Absolutely. CaseMark generates a multi-phase design and approval process with specific review periods for space plans, construction documents, and revisions. All timelines are customizable to match your transaction requirements.

How does the output handle the relationship between Substantial Completion and rent commencement?

CaseMark drafts Substantial Completion criteria that tie directly to your lease's rent commencement mechanics, including punch list procedures, certificate requirements, and any delay provisions that affect the commencement date.

Can I customize contractor requirements and insurance minimums?

Yes. The generated Work Letter includes sections for contractor qualifications, insurance minimums, working-hour restrictions, and building-specific rules. You can review and adjust all provisions before finalizing the document.

Is the output ready to attach as a lease exhibit?

CaseMark formats the Work Letter as a formal exhibit with proper lease cross-references, recitals, and conflict-of-terms provisions. After your legal review, it's ready to attach to the executed lease as a binding exhibit.
