Redrafting of existing building archived files into ACAD including some revised layout for the building interior; 1 story warehouse will be divided into 3 bays. South portion of the building will be redesigned to accommodate a food production facility on the main and second floor. The second floor will also have a few offices added. Also the exterior exit stair from the second floor will have to be relocated to accommodate a few changes to the exterior elevations to the North, South, and West of the buildings. Looking for a quick turn around on this project. More detail to follow along with attachments.

Aim The aim of the work is to identify modes of vibration of a component and the associated natural frequencies by different techniques and compare the values. 1. Finite element analysis Prepare a finite element model of the component and extract the first six modes of vibration and associated natural frequencies. You are recommended to use the finite element analysis software, ANSYS to undertake your analysis.You will need to measure the component to obtain its dimensions you will also need to find out what material it is made of. Provide a rationale for your model commenting on your assumptions and choice of constraints, elements, nodes, etc. Comment on each of the mode shapes. 2. Hand Calculations Carry out appropriate hand calculations to estimate the first few modes to confirm your finite element analysis results are sensible. You will need to reference the source of your calculations. 3. Experiment analysis The component will be excited by an impact hammer at different locat...

I am looking for a short report (max 2500 words) on the short (2-3 year) and medium term (5-10 years) future technology in HVAC (heating, ventilation and air conditioning) systems for residential purposes. The purpose of this report is to be used in conjunction with a feasibility study that we are using to determine whether to retrofit an existing HVAC system (approx. 10 years old) in a large UK home based on the currently available systems (eg. VRV / VRF) or whether to there is an imminent step-change in technology that would justify waiting. The report should outline the key differences between the existing technology (based on a conventional 4 pipe boiler+chiller+fan coil system), current technology and any anticipated changes or breakthroughs that may be on the horizon. An approximate comparison of relative energy and maintenance costs (using current technology as a baseline) would be informative. No details as to the location of the property in question can be disclosed as we ...
