Dry-In and Weatherproof a Small Practice Structure

A. Finished-Project Specification

Scope: one completed dry-in and weatherproofing assembly covering every exterior wall elevation of the capstone shed structure, including WRB, one flashed and installed new-construction window, one flashed and installed prehung exterior door, all approved service penetrations, rainscreen and drainage components, the selected siding system, exterior trim, designated sealant joints, a completed exterior water-control inspection, and a formal envelope closeout and handoff.

• Window and door units: one specified new-construction flanged window and one specified prehung exterior door, with manufacturer-approved fasteners and shims.
• Rainscreen and siding: furring or drainage-mat material, insect screen, the selected horizontal lap or vertical board-and-batten siding stock, starter and corner components, and corrosion-resistant fasteners matching each system's schedule.
• Trim and sealant: approved exterior trim stock, designated sealant products, backer rod, and primer where required.
• Penetration hardware: approved boots, gaskets, mounting blocks, vents, and utility-block covers matching the penetration schedule.
• Documentation: one exterior water-control inspection record and one envelope closeout record for the capstone structure.

WRB and flashing continuity	Continuous shingle-lap coverage across every elevation, corner, and transition, with all seams and penetrations treated
Window and door installation	Level, plumb, square, operational, correctly flashed, and air-sealed per Projects 4 through 9
Rainscreen and siding	Continuous drainage and ventilation path preserved behind correctly exposed, fastened, and aligned siding
Trim and sealant	Trim installed with required reveals and clearances; sealant present only at designated joints with drainage openings left clear
Penetrations and vents	Flashed in shingle-lap order, supported, and operational without blocking drainage or ventilation
Inspection and closeout	Full exterior water-control inspection completed, every punch-list item corrected and reinspected, and envelope closeout record signed

E. Document Review, Readiness, and Sequencing Plan (Steps 1–6)

1. Obtain the capstone wall plans, window and door schedules, cladding elevations, WRB system, flashing details, rainscreen design, penetration schedule, and product instructions. Confirm the revision date of each document against the project's document-control log.
2. Confirm that the framing and roofing handoff records from Books 4 and 5 are complete. Verify the handoff record shows the required structural and roofing approvals before proceeding.
3. Inspect wall sheathing, structural connectors, rough openings, roof-to-wall transitions, foundation or floor-platform interface, and exterior access. Apply the Project 1 inspection method and issue an updated envelope-readiness decision for the capstone structure.
4. Prepare a complete material, tool, safety, weather-protection, access, staging, and inspection plan. Sequence the plan by elevation so each opened wall area reaches WRB-complete condition or is otherwise protected before the end of each work session.
5. Identify the selected cladding system for each elevation and document any approved transitions. Confirm whether each elevation uses the Chapter 12 horizontal lap system, the Chapter 13 vertical board-and-batten system, or an approved documented transition between them.
6. Correct authorized sheathing and opening deficiencies before covering the walls. Remeasure any corrected rough opening or wall area before proceeding to WRB installation.

F. Water-Resistive Barrier and Base Flashing (Steps 7–8)

7. Install base flashing and the WRB in bottom-to-top shingle-lap order. Apply the Project 2 course, corner, lap, and fastening method to every elevation.
8. Wrap corners, treat transitions, protect openings, and complete WRB seam and damage repairs. Apply the Project 3 seam-taping, penetration-treatment, and repair method before any opening is flashed.

G. Window and Door Installation (Steps 9–12)

9. Flash the window rough opening and install the specified new-construction window. Apply the Project 4 sill-pan flashing method, then the Project 5 setting, shimming, and fastening method.
10. Complete window flange flashing, head flashing, sill drainage, operation checks, and interior air sealing. Apply the Project 6 exterior flashing and interior air-seal method without blocking sill-pan drainage.
11. Install the exterior-door sill pan and set the specified prehung door. Apply the Project 7 sill-pan method, then the Project 8 setting, shimming, and fastening method.
12. Complete door jamb flashing, head flashing, threshold sealing, operation checks, and interior air sealing. Apply the Project 9 exterior flashing and interior air-seal method without blocking threshold drainage.

H. Penetrations, Rainscreen, and Siding Layout (Steps 13–15)

13. Prepare and flash all approved pipe, duct, cable, electrical, and fixture penetrations. Apply the Project 16 shingle-lap penetration-flashing method before the associated utility block or fixture is installed.
14. Install the approved rainscreen furring, drainage mat, base venting, and insect protection. Apply the Project 10 method across every elevation, preserving the drainage gap around openings, corners, and penetrations.
15. Establish siding starter, corner, opening, and course control lines. Apply the Project 11 layout method, confirming level, plumb, and drainage-opening protection at every reference line.

I. Siding, Trim, and Penetration Finishing (Steps 16–19)

16. Install the selected horizontal lap or vertical board-and-batten siding system on each approved elevation. Apply the Project 12 method or the Project 13 method as selected for that elevation, without mixing details across an elevation unless an approved transition is documented.
17. Install exterior window, door, corner, and transition trim in the required sequence. Apply the Project 14 method, preserving head-flashing projection and sill drainage at every opening.
18. Install exterior vents, utility blocks, and covers over completed penetration flashings. Apply the Project 17 method, confirming free movement of every damper, louver, or cover.
19. Apply designated sealant joints using approved joint geometry while preserving every drainage and ventilation opening. Apply the Project 15 method, sealing only the joints identified on the approved sealant schedule.

J. Full Inspection, Punch List, and Closeout (Steps 20–27)

20. Inspect each elevation during installation for laps, fastening, alignment, clearances, damage, and drainage continuity. Correct any deficiency found during installation before proceeding to the next layer on that elevation.
21. Complete the full exterior water-control inspection from Chapter 19. Apply the Project 19 inspection method to the entire capstone structure, using concealed-work photographs and records to verify covered details.
22. Prepare a punch list identifying location, condition, required correction, responsible party, and reinspection method. Include every deficiency found during the Step 21 inspection, whether structural, water-control, or documentation-related.
23. Correct every failed item and repeat the applicable inspection. Do not close out any punch-list item without a documented reinspection result.
24. Conduct approved localized operation, drainage, or water-control observations after product cure conditions are satisfied. Follow the defined protocol with interior monitoring and stop conditions; do not represent the result as proof the entire structure is watertight or airtight.
25. Clean the exterior, remove unauthorized temporary materials, and protect the completed envelope. Confirm the site is free of debris, cut-offs, and temporary flashing or covering materials before documentation.
26. Compile product records, measurements, photographs, concealed-work evidence, inspection results, corrections, maintenance requirements, and warranty information. Assemble the complete capstone documentation package referenced throughout this project.
27. Complete the envelope closeout and formally hand the dried-in structure to the mechanical and interior trades. Issue a pass, conditional-pass, or failed-envelope decision and record the responsible party for any remaining open item.
