SECTION 024119 - SELECTIVE DEMOLITION

PART 1 - GENERAL

1.1 SECTION REQUIREMENTS

A. Items indicated to be removed and salvaged remain on Government property. Carefully detach from existing construction, in a manner to prevent damage, and deliver to Government.

B. Submittals:

1. Predemolition Photographs: Show existing conditions of adjoining construction and site improvements. Submit before Work begins.

2. Work Plan: Submit a written work plan for Government review and approval before beginning any selective demolition. At minimum, the work plan shall address:

a. Truss Inventory: A marked-up drawing or schedule identifying, by location, each existing truss to remain, each to be removed as damaged, and each new truss location, based on the Contractor's field survey of actual conditions (no as-built drawings exist for this structure). This inventory shall reconcile with the truss quantities specified in the SOW Project Scope and Bid Schedule prior to demolition.

b. Phasing and Sequencing: Sequence of demolition and installation activities, including confirmation that demolition of existing trusses and roofing will not begin until the delegated truss design submittal required under Specification Section 061753 has been reviewed and approved by BLM, so the extent of time the structure remains without a complete roof/truss system is minimized.

c. Temporary Shoring and Bracing: A plan for temporary shoring, bracing, or other stabilization of remaining wall framing, posts, and adjacent trusses during removal of the existing metal roof and damaged trusses, addressing any loss of building stability while work is in progress.

d. Weather and Wind Contingency: Given that the original structural failure was wind-related, the work plan shall identify wind speed or forecast thresholds above which demolition or open-roof work will be suspended, and measures to secure loose materials, partially removed roofing, and exposed framing against wind during the course of the work.

e. Protection of Elements to Remain: Measures to protect the existing east end wall siding and any other existing construction not indicated for demolition, consistent with the Requirements for Building Reuse below.

f. Schedule Milestones: Proposed dates for demolition start/completion, coordinated with the Project Schedule in the SOW and with submittal approval milestones.

C. Government will occupy portions of building immediately adjacent to selective demolition area.

Conduct selective demolition so Government operations will not be disrupted.

D. It is not expected that hazardous materials will be encountered in the Work. If hazardous materials are encountered, do not disturb; immediately notify COR. Hazardous materials will be removed by Owner under a separate contract.
