10

Verify concrete stresses in columns /

compare with in-situ concrete strength

Building Engineer is to verify in-situ

strengths of concrete and compare

with stresses in columns. Detailed

Engineering Assessment required for

building

11

floors

12

Cracking in beams

Hairline cracks to beam on

underside of 2nd floor

13

Cracking in beams

of 5th floor

14

Column in North West corner - confirm

vertical load path throughout building and

stress in column at ground floor level

15

Confirm Loadpath / Column Design

Building Engineer is to perform

detailed calculations and concrete

tests to prove column size; Column

to be reinforced if required

16

Vertical Load Path to Ground Floor

Transfer of loading through

building to external column

on northwest corner of

building

Column at corner is

triangular with different

dimensions to typical

column

Building Engineer to check

design of corner column and

transfer beam

Building Assessment to review if

this column is a key element and

as such should be provided with

a protective barrier.

What is impact of loss of

column?

17

Exposed reinforcement to slab overhangs in

future lift shaft and front elevation

18

Deterioration of Building

Structure

Deterioration of concrete

and corrosion of

reinforcement to slab

overhangs on lift shaft and

west elevation of factory

building

19

Remove demolition rubble from roof slab and

provide drainage/waterproofing of newly

exposed roof slab to prevent corrosion of

reinforcement

20

Removal of Demolition

Rubble/Waterproofing of Roof Slab

Demolition rubble to be

removed from the roof

Ensure that the recently exposed

concrete roof slab is provided with

drainage and waterproofed, at

locations where the slab has been

damaged, to prevent ingress of

water to the building structure

Priority 1(Immediate - Now)

Item 1 and actionsStructural drawings provided do not match the as-constructed structure

particularly with respect to column locations and the inclusion of building

movement joints.

• None required

Priority 2(within 4-months)

• Factory Engineer to prepare as-built structural drawings.

• A Detailed Engineering Assessment of the Factory is to be

commenced, see attached scope.

Priority 3(within 6-months)

• Produce and actively manage a loading plan for all floor plates

within the factory giving consideration to floor capacity and

column capacity.

• Detailed Engineering Assessment to be completed.

24

This Schedule develops a minimum level of information, Analysis and testing expected as part of a Detail Engineering Assessment.

The Building(s) have been visually assessed and it is deemed necessary that a detailed engineering assessment be carried out by a competent Engineering

Team employed by the factory Owner.

We expect that the following will be carried out:

1. Development of Full Engineering As-Built Drawings showing Structure, loading, elements, dimensions , levels, foundations and framing on Plan,

Section and Elevational drawings .

2. The Engineering team are to carry out supporting calculations with a model based design check to assess the safety and serviceability of the building

against loading as set out in BNBC-2006, Lower rate provisions can be applied in accordance with the Tripartite Guidelines following international

engineering practice, justification for these lower rate provisions must be made.

3. A geotechnical Report describing ground conditions and commenting on foundation systems used/proposed.

4. A report on Engineering tests carried out to justify material strengths and reinforcement content in all key elements studied.

5. Detailed load plans shall be prepared for each level showing current and potential future loading with all key equipment items shown with associated

loads.

6. The Engineering team will prepare an assessment report that covers the following:

• As-Built drawings including

• Plans at each level calling up and dimensioning all structural components

• Cross sectional drawings showing structural beams, slabs, floor to floor heights, roof build-ups and Basic design information of the

structure

• Highlight any variation between As-built compared to the designed structure

• Results of testing for strength and materials

• Results of geotechnical assessment and testing/investigation

• Details of loading, inputs and results of computer modelling

• Commentary on adequacy/inadequacy of elements of the structure

• Schedule of any required retrofitting required for safety or performance of Structure
