HomeMy WebLinkAbout2005 CON Jaynes Corporation - Library Construction Change Order #6CONTRACT CHANGE ORDER C/O Number: 006 TO (Contractor): Jaynes Corporation C/O Initiation Date: January 12, 2005 8530 La Mesa Blvd. Suite 306 Project National City Public Library La Mesa, California 91941 Contract No.: 1028 A Change Order is hereby recommended for the following work in the amount identified in this document: DESCRIPTION OF CHANGE: 1. ASI # 041; COR # 063: Revise Roof Assembly #2 to Coordinate with Structural Design.......$ 31,424.00 REASON FOR CHANGE: This roof area was designed to put the waterproof membrane under a topping slab so that mechanical unit installation and maintenance workers and materials would not damage the membrane and cause leakage into the library below. The topping slab approach also limits noise from the units from radiating down into the building. Architecturally, we are required to slope the topping slab to drain (1/4" per foot) which causes the top surface to be up to 13 inches thick over the structural slab. The structural engineer designed this area of open roof and covered mechanical penthouse for a four inch thick lightweight concrete topping over sloping insulation and the structural slab. This design approach saved a substantial amount of structural steel (both vertical and lateral) over designing for a much thicker slab and also offers the benefit of additional thermal and acoustical insulation for the history room and offices below. ASI No. 41 clarified that the slope would be created by a lightweight concrete topping (four inch maximum) over high density foam (where necessary), over protection board, over waterproof membrane, and over the structural slab. The contractor is entitled to a change in scope on this matter and the City does receive added value for this change. COST RECONCILIATION: $ 31,424.00 Costs were reviewed by the Construction Manager and the City and negotiated to the satisfaction of the City. The foregoing increase in price is in full settlement of all entitlements directly or indirectly arising out of this change. Construction Contract Accounting Summary: The Original Contract Amount $ 11,476,444.00 Net change by previously authorized Change Orders $ 124,433.00 Revised Contract Amount due to previous Change Orders $11,600,877.00 With this Change Order request the Cact amount increases by $ 31,424.00 $ 11,632,301.00 New Revised Contract Amount Change in Con ' - .

However in simple terms the building was designed to support four inches of lightweight concrete on top of the waterproofing membrane on the roof around the five air handlers. This concrete was specified to allow maintenance personnel to work around the air handlers without damaging the waterproofing membrane. During construction the of slope around the equipment was identified as an issue by the contractor. Architect Supplement Instruction No. 41 showed that foam needed be installed on top of the waterproof membrane, below the lightweight concrete to create positive drainage of the roof. This foam thickness varies from 0.5 to 9 inches. Each piece of foam is manufactured in the specific shape for this roofing system, which can be seen to be quite complicated. This information, though contemplated, was not shown on the original plans by the architect. Consequently the contractor did not include this foam in the bid. The change order is necessary for the integrity of the waterproofing system. J CEnvironmental Review (-Financial Statement X N/A Approved By: Change order number six is for $31,424. Funds are budgeted for this change order in the project account numbers 241-409-500-598-1583 and 24•-409-500-598-1583.
