Workflow

Overview

CaseMark's TI Work Letter skill automates the drafting of Tenant Improvement Work Letter exhibits for commercial leases. It generates comprehensive, transaction-ready documents covering design approval processes, construction requirements, TI Allowance disbursement mechanics, and Substantial Completion standards — all aligned with your master lease terms.

Drafting Tenant Improvement Work Letters is one of the most time-intensive tasks in commercial leasing. Each exhibit requires careful coordination between lease terms, construction specifications, allowance calculations, and multi-phase approval processes. A single oversight in definitions or payment mechanics can lead to costly disputes during build-out.

CaseMark automates the entire TI Work Letter drafting process by analyzing your lease agreement, allowance terms, and base building scope to produce a comprehensive, transaction-ready exhibit. The AI ensures every section — from definitions and approval timelines to disbursement mechanics and Substantial Completion standards — is internally consistent and aligned with your master lease.

How it works

1. Upload your executed or draft lease, TI allowance terms, and base building specifications
2. AI analyzes lease terms and drafts a comprehensive Work Letter exhibit with all required sections
3. Review and customize definitions, approval timelines, payment mechanics, and construction requirements
4. Export the finalized Work Letter as DOCX or PDF, ready to attach as a lease exhibit

Questions

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

You'll need your executed or draft lease agreement, TI allowance terms (total amount, per-RSF calculation, eligible cost categories), and base building scope details. CaseMark uses these inputs to draft a Work Letter that aligns precisely with your lease terms.

Does the Work Letter include payment disbursement mechanics?

Yes. CaseMark generates detailed TI Allowance disbursement provisions including draw request procedures, lien waiver requirements, Over-Allowance payment obligations, and retainage terms. All payment mechanics are tied to the allowance structure you provide.

Can I customize the design approval timelines?

Absolutely. CaseMark drafts a four-phase design and approval process with standard review periods (10–15 business days), but you can adjust all timelines, resubmission windows, and approval conditions to match your transaction requirements.

How does the Work Letter handle conflicts with the master lease?

CaseMark includes a clear hierarchy-of-documents provision specifying which document controls in the event of a conflict between the Work Letter exhibit and the master lease, ensuring legal certainty for both parties.

Is the output suitable for institutional-quality commercial leases?

Yes. CaseMark's TI Work Letter includes institutional-grade provisions covering Substantial Completion standards, contractor insurance minimums, working-hour restrictions, lien protection, and building code compliance — all standard for Class A commercial transactions.

Can I use this for different types of commercial properties?

CaseMark's TI Work Letter skill adapts to office, retail, industrial, and mixed-use commercial leases. The AI tailors construction requirements, permitted use references, and base building scope based on the lease and property details you provide.
